first)!
• If it works for you, that’s great
• Let’s be nice to each other
• You don’t need to read every word of every slide
• Let’s keep our contributions succinct and focused on
the topics or exercises I set
• Phones on silent. Snacks and drinks fine
This workshop needs you: share your Wisdom!
Part one: Climate
Science
A Quick Climate Quiz: let’s see what
you know
What are the benefits of a better activist
understanding of climate change?
Why Should Activists Understand Climate Science?
To improve understanding of
the problem amongst the
general public, media and
government
To help correct
misinformation that
exists in the public
sphere
It is important that we can
confidently answer and explain
our subject
Understanding science means we
can convey clear messages and
avoid confusing language
nuances
It helps us tell the truth
about the climate crisis
Using clear terms and language
can stop climate denial
arguments before they are raised
Good knowledge of the science
allows us to paint vivid pictures
and create interesting narratives
To give us credibility as activists
and show that we can be trusted
as speakers on the topic
To ensure that our talks, presentations, discussions,
debates are accurate and persuasive
A Climate 101: Natural Factors
that Drive Earth’s Climate
The Sun and its Cycles
• The sun has very small and subtle effects
on the Earth through an 11 year and 63
year cycle
If the sun was warming the Earth, we would see greater warming during:
days not nights, summers not winters, in the upper atmosphere not the
lower- The opposite currently the case.
Ocean Currents
Oceans can move heat to the poles and cause warming. We would see
the lower ocean warm faster than the surface. The opposite currently the
case
Volcanic Activity
Volcanoes release only 1% of
the CO2 that humans do. They
are too weak to cause current
warming
Particles from
volcanic eruptions
can cause
temporary cooling
Orbit and Axis tilt
variations
(Milankovitch
Cycles)
CO2 levels have been very low in the recent geological period so subtle wobbles in orbit have
driven our climate. If these cycles were still in control the Earth would be going into a period
of cooling not heating.
Reflective Cooling of Cloud and Ice Cover
(Albedo Effect)
Light surfaces reflect more of the Sun’s heat. Human warming is melting ice which
then adds to the heating by reflecting less energy back into space
The atmosphere has warmed so there is more moisture and thus more cloud cover,
which has contributed a slight cooling effect
How does the Greenhouse Effect Work?
The Greenhouse Effect: Keeping the Earth Warm
• Certain gases have the property of trapping heat in our
atmosphere
• Instead of the average global surface temperature
being -18°C, it is a much more ambient 14°C
• Water, carbon dioxide, methane and nitrous oxide are
all GHGs
The Greenhouse Effect was scientifically
demonstrated and quantified in the 19th
century by John Tyndall and Svante
Arrhenius
What determines GHG potency?
1) Heat absorption (of a single molecule)
2) Duration (in the atmosphere)
3) Quantity (in the atmosphere)
• Water vapour condenses from a GHG into a liquid at
Earthly temperatures, so is limited BY temperature
• Other GHGs must first warm the atmosphere to allow
larger amounts of water to stay as a gas and further
amplify the warming
Human-Caused (Anthropogenic) Warming
1. CO2 levels are rapidly building in the atmosphere (we measure it)
2. We know this CO2 is from our fossil fuels (isotopes tell us)
3. The Earth is warming (we’re measuring it)
4. The pattern of warming is exactly what we would expect from GHGs (and not natural
factors- see next slide
• Humans are emitting 40 gigatons of CO2 per year
• CO2 reabsorption is declining (we are destroying carbon sinks and CO2 emissions are
rapidly rising)

Earth’s climate Since the arrival of
animal life (650 million years ago)
Hot House Earth States
For most of the past 650 million years,
the Earth has been free of polar ice and
up to 9°C hotter than today
Higher levels of CO2 from volcanoes
or less photosynthesis trigger these
phases
Life can thrive during these periods, but
needs millions of years to adapt to them
Ice House and Snowball
Earth Events
Number of ice ages: around 7
Ice ages are the result of reduced
CO2 levels and greenhouse effect
due to increased weathering of
rocks and/or photosynthesis
Ice House: Frozen at the poles
Snowball: Frozen to the equator
Climate Change and Extinction Events
• The 5 mass extinctions saw temperature rises of 4-7°C over 20,000 to 200,000 year periods
• In each case there was 75-95% global loss of species
• Each time, biodiversity and climatic stability took millions of years to recover
There have been 5 mass extinctions
(which means at least 75% of species die
out)
Extinction event triggers: volcanoes,
asteroids and/or cosmic events
These triggers lead to: spikes in
atmospheric CO2 and tens of millennia of
climate change
The Holocene Extinction
In the 700 million year history of complex life on
Earth, the arrival of the “human super-predator”
is unprecedented in terms of climate and
biodiversity and it represents:
Between 1850 and 2150 humans could raise the Earth’s temperature by 5-10°C, resulting in civilisation collapse or
human extinction
• The fastest ever sustained rate of
extinction (200 species a day)
• The fastest ever sustained rise in
atmospheric CO2 levels
• Possibly the fastest ever rise in
temperatures
• The fastest ever rate of ocean
acidification
At current rates the sixth mass
extinction will have occurred by the
end of the century (75% by 2100)
How should we talk to people about climate science? What
are your tips?
Tips on Discussing Climate Science
• Capture peoples’ imaginations with excitement and passion.
• Be friendly and respectful; avoid combative arguments and telling people they are wrong.
• Minimise statistics, data and jargon
• When a record is broken, is it since: we started measuring with instruments, industrial times, human
civilisation began or since complex life arose on Earth? Be clear to stop confusion or unnecessary
fact challenges
• Talk about trends in climate/weather and record breaking events. Avoid citing single out-of-the-
ordinary weather events as evidence
• Talk about the speed of change over the amount of change (there’s been more CO2 and its been
hotter, but never so fast)
• When refuting a climate denial argument protect ego: “I can see how information X could lead you
to that conclusion…”
• Focus your arguments on the scientific consensus of man-made climate change i.e. the Green
house effect, human CO2 emissions, rising CO2 levels, the Earth is warming, current climate change
is CO2 driven
• Climate sceptics often uses facts and statements that are true (but out of context or
misunderstood) so start your response by agreeing. “You’re absolutely right”, “That is a really
interesting point you raise” or “ a great question”
• Avoid “”but no” or “that’s wrong” etc.
• The longer you can use the language of agreement, the longer your counterpart will listen
• Connect the abstracts of science to thinks people understand and use emotion
Classic denial science arguments:
1. It’s been hotter and there’s been higher levels of carbon dioxide in the past 4.5 billion years;
2. They grew grapes in Newcastle;
2b. What about the medieval warm period?
2c. There are glaciers that are currently growing
2d. There are glaciers that have retreated in the recent past
3. The Earth is in an Ice age and is due to go into a period of cooling
4. Ice core records for the last 800,000 years show that temperature rises came before the carbon
dioxide rises. Doesn’t this disprove the theory of climate change?
5. It’s natural not humans
6. Scientists use computer models which are inaccurate or speculative
7. Climate change is a scam that scientists are encouraging so they get funding
8. We need CO2 to feed plants so it is good for the earth
9. If water vapour is a greenhouse gas, why are we not worried about?
10. Climate change is just a theory
11. There’s nothing we can do about it
12. The idea that climate change is a serious threat to humans is an exaggeration
1. The Earth has indeed been much hotter with higher levels of carbon dioxide in the past 4.5 billion years and
life can thrive as long it has had millions of years to adapt through evolution. The speed of the changes
being experienced now are unprecedented and it is this speed and the inability of humans and the natural
word to respond that makes our current situation so dangerous
2. All of the changes referenced are local or regional temperatures. What matters is the overall global average
(mean)
3. The Earth is indeed in an ice age and until humans started releasing huge amounts of CO2 at a rapid rate,
we would have expected orbital cycles to take us out into a phase of cooling over the next 50,000 years.
These orbital cycles have now been overridden by the large increase in CO2 emissions. The last time there
was this much CO2 in the atmosphere, the north pole was ice free
4. During the last 2.6 million years, the levels of atmospheric CO2 have been very low and we have been in an
ice age. This has allowed cycles in the Earth’s orbit and tilt to be the primary driver of temperature changes
instead of greenhouse gases. Each time orbital cycles pushed the earth into a warming phase, soils and
melting ice released CO2, which then amplified the warming triggered by the orbital cycles. And this is why
warming has begun prior to CO2 rises during the Quaternary Ice Age.
Responses to These Arguments
5. Solar patterns, ocean currents, orbital (Milankovitch) cycles, cloud cover and albedo effect have all had
their effects measured and can be ruled out conclusively. Aside from rising global temperatures, warming:
poles, nights and winters are characteristic of greenhouse warming. Shrinking thermosphere, cooling
stratosphere and measured spectral characteristics of energy reflecting back into space, are all specifically
characteristic of greenhouse warming
6. Climate models are built from everything we know about the mechanisms that control the Earth’s
climate. They can be tested by running them over periods in the past to see if they accurately match the
records we hold over that time period. The predictions they are making have been broadly accurate and
if anything they have underpredicted the effects of rising CO2 levels
7. Concerns about human emissions have been around since Victorian times, climate science is funded
by a variety of sources all around the world, the science has been done by hundreds of thousands of
scientists from every country in the world, oil companies have more of a motive to distort the evidence,
oil companies themselves privately acknowledged the science as far back as the 1950s, the evidence is
thorough
8. There is plenty of CO2 for plants, just because a substance has positive uses, doesn’t mean that it can’t
have negative properties, we only want to prevent adding extra greenhouse gases to the atmosphere,
not take away that which was already there prior to humans
.
9. Water vapour is a condensable greenhouse gas. The Earth’s temperature poses a limit to how much water
vapour the atmosphere can hold. Only if another factor (such as CO2) drives up temperatures can the amount of
water vapour increase. When that happens it can then contribute to warming. Water vapour on its own cannot
drive temperature change
10. When we say “theory” in an everyday sense we imply an idea or guess. A scientific theory is an idea that can be
and has been tested to be true. Scientific theories underpin much of the modern world and are trusted without
question. When a new means of testing them arises, scientists will do so
11. It is true that a certain amount of warming is on its way due to greenhouse gases already emitted. Scientists
believe humans can reasonably adapt to 1.5 °C. Rises above this threshold will pose a serious threat to our
economies, societies and civilisation. Scientists, economists, many policy makers and social scientists have told us
that we can prevent climate change. The legislation, policy, taxation, funding and technological changes needed
are all clearly understood, beneficial and much cheaper than inaction. Climate change dangerous to human
civilisation will only happen if we choose not to act, rather than in all scenarios
12. Scientists have been careful to give conservative and well evidenced information to policy makers. Their
conclusions are some of the most thoroughly examined investigations that there have ever been. What is in fact
becoming clear is that rather than exaggerate, scientists conclusions have transpired to have significantly
understated/underpredicted Earth’s sensitivity to greenhouse gases and that dangerous climate change is coming
faster and more severely than was previously thought. Work done by scientists and academics have shown that
human civilisation is very sensitive and vulnerable to climatic changes. The more complex the civilisation the more
sensitive it becomes

Talking with People About Climate Change
Who might we be talking to about the Climate Crisis (Think
situations, relationship etc)? What are the challenges and
benefits of these different settings?
Reasons/arguments for not acting on climate change
There’s
nothing I can
do about it
It’s not happening
It’s natural
or beyond
our control
It’s already too
late
Climate
change is a
scam
Don’t want to give up
lifestyle or technology
Not
interested
Too stressed,
poor or busy
China
aren’t
doing
anything
Discuss in Groups
Exercise: the Polar Bear Problem
The imagery of environmentalism has been so long focused on pictures of sad
animals that it has been attacked for over sentimentality and failure to connect to
the human catastrophe of the climate crisis
In groups make a list of:
1. the issues that people
prioritise in their day to day
lives?
2. Things that make up a
person’s identitiy
How will climate change impact
on these things?
What factors
make a good
conversation?
What factors
make a bad
conversation?
In pairs, share a
climate
conversation that
went well and
then one that did
not go so well
• Did you both listen to each other’s points? (ensure that you listen to the other person)
• Was it a good time for you both to talk?
• Did you use positive or negative language
• Were either of you feeling tired, ill, hungry, sad, stressed, rushed, angry?
• Was there a positive outcome?
• Did you connect/bond with the other person?
• Did you lean towards agreement or disagreement
• Did you learn about each other?
• Did one person talk a lot more than the other?
• Did both people get to express their views and opinions?
• Did both parties get something out of the discussion?
• How did you feel at the end of a conversation?
• Did the conversation result in positive change?
A bad time to talk: Reasons why we might not start a climate
conversation
• Are you feeling, happy, confident, physically well and refreshed?
• Is the person in a rush or angry? (annoying somebody won’t usually encourage you to take on
board what you are saying)
• Is a person tired or unwell?
• Is it a good time of day (too early in the morning or late at night)?
• Is this a person you feel able to connect with effectively (think gender, social, cultural issues etc)?
• How important is it to talk to this particular person? Are you choosing the right battle?
• Is there a difficult relationship or bad history between you and this person. Are you the right person
to talk to this person?
• Do you feel safe?
• Is the setting or environment right to have this conversation?
• A poorly timed or conducted conversation might do more harm than good to the climate cause
What tips can help
us to have an
effective climate
conversation?
• Who is the person you are talking to? What matters to them? Show interest in them and learn about
them
• What do you have in common where can you connect as people and on the subject of the Climate
Crisis
• Listen to a person’s opinions. What do they think about the Climate Change or anything for that
matter?
• Don’t force the conversation straight to the climate crisis. Find out how the person’s day is and what
they are up to?
• Don’t attack, judge or blame. Start with what the person is doing right. Put emphasis on where you
agree
• Smile, share humour, compliment, focus on making sure that person is enjoying your interaction
• Mirror body language and tone of voice, but be mindful of body language, personal space and eye
contact
• Be humble, peaceful and apologetic as required, especially if your are disrupting somebody’s life
• Use “I” statements, share emotion and speak from the heart
• As a protester of activist, just having a positive interaction is good. Later on they will remember a positive
image to counter any media or public criticism
The Bottom Line:
As activists we need to
create positive
experience for
individuals we interact
with through listening,
empathy and our
constructive behaviour
• Avoid Blaming
• Holocracy
• Post consensus
• Non-violence
• Civil disobedience
• Sacrifice
• We only need 3.5%
In your groups can
you make one or two
points, views,
justifications or
scenarios that relate to
having climate
conversations and one
of these key concepts
and approaches
Defending Climate
activism: Unravelling
the Myths of the
Critics
Climate Activists are Alarmist
Meaning: The risk and danger of climate change has been have been exaggerated
for financial or other gain of as a sort of conspiracy theory
Responses:
• The scientists clear: this is the biggest threat to face our species this century
• This isn’t a crank theory, least 97% of scientists agree
• Yes I’m alarmed and for good reason
• If anything, scientific reports have chronically understated the problem. Current
climate change is decades in front of what the most pessimistic projections were
predicting
• Alarmism is a concept that spread to to try and attack the climate movement by
weaponizing the truth and turning it back on them
• We have a duty and need to tell the truth even if it is hard to hear
Imagine in World War Two if:
“Prime Minister Churchill! The Nazis are
planning to start a war in Europe!”
“Come on now. Don’t be so alarmist.”
Doom mongering makes people feel powerless
and scaring people doesn’t work!
• We’re not doomed, we just need to act
• There is nothing inevitable about the Climate Crisis
• We have to tell the truth and this is very serious
• People do respond positively and quickly to serious
emergency situations
• Fear and anxiety are powerful human emotions that
evolved to motivate us into action
• Shocking and scary images and information has been
used in all kinds of public information campaigns
• “Doom Monger” is a way of turning the truth into a
criticism, paralysing an effective strategy
• Extinction Rebellion has proved that stark messaging
is very effective
• Don’t stop scaring people, remove the reason for
them to be scared
Imagine in World War Two if:
“Prime Minister Churchill! The Nazis will take
over our country if we don’t do something!”
“Come on now. Stop scaring people.”
Going low carbon will damage our economy
The cost of climate inaction will
be greater than any other
economic cost humans have
ever incurred
No cost is too great
when the lives and
wellbeing of billions
of people and our
future civilisation are
at risk
The transition to a
low carbon
economy will
create many
millions of jobs
and generate
trillions of dollars
in savings in
health and security
It is wrong to pay
for our prosperity
with the lives of
our children and
future civilisation
There is no
economic
argument for
inaction or
acting too
slowly
There are no jobs on a
dead planet
Imagine in World War Two if:
“Prime Minister Churchill! The Nazis will take
over our country if we don’t do something!”
“I’m sorry but a war economy will cost too
many jobs.”
The climate movement is white and middle class
• It is appalling that austerity, poverty and zero hours contracts have left so many people
on the breadline that they have not the time or resources to explore or express their
views about the future of their planet
• Many minority groups still don’t feel safe to protest as they are still treated differently o
perceive so, by the police
• As a person of privilege, I am going to protest on behalf of those who are unable to or
feel unsafe to do so
Climate protesters tactics are causing
disruption to peoples’ lives
• The disruption caused by climate change will be millions of times greater. Billions will die, Billions more
will be displaced or impoverished
• It is tragic that 31 years (1988) after scientists warned the world of the threat that human greenhouse
gas emissions posed to our civilisation and the natural world, and after letters, petitions, marches and
lobbying, that successive governments has allowed us to come to the final threshold of the point of
dangerous climate change and failed to act. It is therefore tragic that frightened and concerned law
abiding citizens have been forced to use peaceful civil disobedience in order to safeguard the future
wellbeing of their children.
• The tactic of civil disobedience has been used many times to bring about
positive change
• In Britain there has always been an acceptance that doctors, nurses and
teachers can go on strike and cause economic disruption and even
personal suffering to secure better working conditions or pay
Climate activists are radicals, extremeists
and Anarchists
Extinction rebellion are extremists, radicals and
anarchists
XR protesters are
peace
organisation
assembled of
people from all
ages and all social
spectrum most of
who have never
had any dealings
with the law
Peaceful civil
disobedience is
legitimate tactic
used by many
groups who have
been
remembered
kindly and
vindicated by the
history books
The most extremist behaviour on this planet right now comes from the rich minority who
are putting the lives and wellbeing of billions and the future of our civilisation at risk, just
so they can get rich
In the face of the death of billions, the displacement of billions, social
and economic global collapse and the loss of most of the species on
Earth, driven by greed and consumption of a small minority, what could
be more understated than a pink boat and a few thousand protesters in
one city for a week
What about China? They are much
worse than us
• We live in the UK we must focus on our emissions
• The UK’s historical emissions and emissions per capita (when
offshore emissions are included) are both higher than Chinas
• A third of Chinese emissions are from the production of goods
consumed in other countries
• It is a good thing that in the UK we have the freedom protest
without fear of repression about an issue of such magnitude
But humans are so insignificant. How
Arrogant to believe we could change the
world so much!
The HIV Needle Experiment…
So Climate sceptics tell us we are so arrogant for
believing that something as small an insignificant could
have such a big affect on something as vast as Earth.
Let’s just see whether they really do believe that logic…
The difference in scale between a virus and a human is
greater than that between a human and the Earth. How
would you feel with this little needle of teeny tiny HIV
viruses?
The Shotgun Experiment…
Some people use the following statement to justify
inaction: “I don’t care what happens to humans. Just as
long as the Earth survives.” Let’s test how much they
really believe this opinion
What would happen if you put a loaded shotgun to their
head?
The shackles of soft denial: how arguments from the
right have been forced upon the climate movement
• People are turned off by doom/alarm/danger
• People feel powerless and feel unable to act
• Everybody knows climate change is a problem
• People can’t connect to problems that are distant
• The climate movement is too negative and problem focused
By repeating these arguments of those who have ideological and financial interest in
the hydrocarbon industry, we are doing their work for them!
The more these things are repeated, the more we make them true
The truth has been turned into a weapon used to attack the climate movement
People can’t connect to things that
are distant to them
We don’t have to be popular
We just have to win
Civil disobedience does not always breed popularity. In the US, the civil rights movement was vilified
by many people and only history vindicated the many who languished in jails. Scientific truth is on the
side of Extinction Rebellion. Be brave and keep going.
Tackling formal debates on climate change
There may be times where you will be called to formally debate or argue your
position on the climate crisis either in an interview, in court, in a university or
conference. How do you approach such a situation?
Rule number one: know your shit.
Stay in control of your emotions
If you don’t know, say so
Exercise: arguing against human-caused climate change
Being able to express your views with confidence and clarity is critically
important so in groups Prepare convincing arguments to advocate one of the
positions below. Use any information you have read or heard and be persuasive
and confident to convince us of your position. Use your phones to do some
research.
1. The Earth isn’t warming
2. The current warming is part of a natural cycle
3. There are too many uncertainties in the science to
say humans are causing the warming
4. Climate change science is being skewed by
scientists who want to get funding
5. The climate movement is alarmist misrepresenting
the science
Argument Tactics and Strategies
• Start a counter argument by agreeing with a part of what the other person has just said
• Acknowledge a good point or argument before breaking it down or re-contextualising it
• Adopt their language and terminology and use it to form your counter arguments
• Own critiques of your arguments/position and turn them around- bring them up first
• Find common ground and point it out where possible
• Make somebody feel good about themselves, feed their ego
• Build your counter arguments from the things they said and premises they use
• Mirror their body language and tone
• Avoid anger or aggression and point out that use of personal language or anger is the sign is a
sign of a weak argument- If an argument is valid it will be so with reason only
• If your opponent gets angry or aggressive, wind down the conversation or diffuse before
continuing the discussion
• “Know thine enemy”-research the arguments against your position well
• Practice arguing against your own position
• Show/indicate to the other person that you appreciate the discussion, conversation or discourse
• Get the other person to agree to individual premises of your argument before presenting it in full
• Disguise the final point to are planning to make in a given statement
• Ask lots of clarifying questions

Extinction Rebellion: Talking about climate change

  • 1. Defending Climate Science and Activism UNDERSTANDING AND COMMUNICATING THE CLIMATE EMERGENCY
  • 2. From Northern Monkey to Climate Junkie: a speaker introduction
  • 3. Workshop • Better understanding and communication of climate science • Thinking about climate conversations • Explaining, promoting and defending XR and climate activism • Winning formal debates
  • 4. • Let everybody’s opinions, views and skills be shared today • This workshop needs your participation • Please ask lots of questions (just pop your hand up first)! • If it works for you, that’s great • Let’s be nice to each other • You don’t need to read every word of every slide • Let’s keep our contributions succinct and focused on the topics or exercises I set • Phones on silent. Snacks and drinks fine This workshop needs you: share your Wisdom!
  • 6. A Quick Climate Quiz: let’s see what you know
  • 7. What are the benefits of a better activist understanding of climate change?
  • 8. Why Should Activists Understand Climate Science? To improve understanding of the problem amongst the general public, media and government To help correct misinformation that exists in the public sphere It is important that we can confidently answer and explain our subject Understanding science means we can convey clear messages and avoid confusing language nuances It helps us tell the truth about the climate crisis Using clear terms and language can stop climate denial arguments before they are raised Good knowledge of the science allows us to paint vivid pictures and create interesting narratives To give us credibility as activists and show that we can be trusted as speakers on the topic To ensure that our talks, presentations, discussions, debates are accurate and persuasive
  • 9. A Climate 101: Natural Factors that Drive Earth’s Climate
  • 10. The Sun and its Cycles • The sun has very small and subtle effects on the Earth through an 11 year and 63 year cycle If the sun was warming the Earth, we would see greater warming during: days not nights, summers not winters, in the upper atmosphere not the lower- The opposite currently the case.
  • 11. Ocean Currents Oceans can move heat to the poles and cause warming. We would see the lower ocean warm faster than the surface. The opposite currently the case
  • 12. Volcanic Activity Volcanoes release only 1% of the CO2 that humans do. They are too weak to cause current warming Particles from volcanic eruptions can cause temporary cooling
  • 13. Orbit and Axis tilt variations (Milankovitch Cycles) CO2 levels have been very low in the recent geological period so subtle wobbles in orbit have driven our climate. If these cycles were still in control the Earth would be going into a period of cooling not heating.
  • 14. Reflective Cooling of Cloud and Ice Cover (Albedo Effect) Light surfaces reflect more of the Sun’s heat. Human warming is melting ice which then adds to the heating by reflecting less energy back into space The atmosphere has warmed so there is more moisture and thus more cloud cover, which has contributed a slight cooling effect
  • 15. How does the Greenhouse Effect Work?
  • 16. The Greenhouse Effect: Keeping the Earth Warm • Certain gases have the property of trapping heat in our atmosphere • Instead of the average global surface temperature being -18°C, it is a much more ambient 14°C • Water, carbon dioxide, methane and nitrous oxide are all GHGs The Greenhouse Effect was scientifically demonstrated and quantified in the 19th century by John Tyndall and Svante Arrhenius What determines GHG potency? 1) Heat absorption (of a single molecule) 2) Duration (in the atmosphere) 3) Quantity (in the atmosphere) • Water vapour condenses from a GHG into a liquid at Earthly temperatures, so is limited BY temperature • Other GHGs must first warm the atmosphere to allow larger amounts of water to stay as a gas and further amplify the warming
  • 17. Human-Caused (Anthropogenic) Warming 1. CO2 levels are rapidly building in the atmosphere (we measure it) 2. We know this CO2 is from our fossil fuels (isotopes tell us) 3. The Earth is warming (we’re measuring it) 4. The pattern of warming is exactly what we would expect from GHGs (and not natural factors- see next slide • Humans are emitting 40 gigatons of CO2 per year • CO2 reabsorption is declining (we are destroying carbon sinks and CO2 emissions are rapidly rising)
  • 18.
  • 19. Key Climate Science Terms • (Climate, thermal, carbon etc) Forcing: • Climate sensitivity: • Amplifier: • Positive feedback: • Negative feedback: • Tipping point: • Proxy record: • Albedo: • Paleoclimate
  • 20. Earth’s climate Since the arrival of animal life (650 million years ago)
  • 21. Hot House Earth States For most of the past 650 million years, the Earth has been free of polar ice and up to 9°C hotter than today Higher levels of CO2 from volcanoes or less photosynthesis trigger these phases Life can thrive during these periods, but needs millions of years to adapt to them Ice House and Snowball Earth Events Number of ice ages: around 7 Ice ages are the result of reduced CO2 levels and greenhouse effect due to increased weathering of rocks and/or photosynthesis Ice House: Frozen at the poles Snowball: Frozen to the equator
  • 22. Climate Change and Extinction Events • The 5 mass extinctions saw temperature rises of 4-7°C over 20,000 to 200,000 year periods • In each case there was 75-95% global loss of species • Each time, biodiversity and climatic stability took millions of years to recover There have been 5 mass extinctions (which means at least 75% of species die out) Extinction event triggers: volcanoes, asteroids and/or cosmic events These triggers lead to: spikes in atmospheric CO2 and tens of millennia of climate change
  • 23. The Holocene Extinction In the 700 million year history of complex life on Earth, the arrival of the “human super-predator” is unprecedented in terms of climate and biodiversity and it represents: Between 1850 and 2150 humans could raise the Earth’s temperature by 5-10°C, resulting in civilisation collapse or human extinction • The fastest ever sustained rate of extinction (200 species a day) • The fastest ever sustained rise in atmospheric CO2 levels • Possibly the fastest ever rise in temperatures • The fastest ever rate of ocean acidification At current rates the sixth mass extinction will have occurred by the end of the century (75% by 2100)
  • 24. How should we talk to people about climate science? What are your tips?
  • 25. Tips on Discussing Climate Science • Capture peoples’ imaginations with excitement and passion. • Be friendly and respectful; avoid combative arguments and telling people they are wrong. • Minimise statistics, data and jargon • When a record is broken, is it since: we started measuring with instruments, industrial times, human civilisation began or since complex life arose on Earth? Be clear to stop confusion or unnecessary fact challenges • Talk about trends in climate/weather and record breaking events. Avoid citing single out-of-the- ordinary weather events as evidence • Talk about the speed of change over the amount of change (there’s been more CO2 and its been hotter, but never so fast) • When refuting a climate denial argument protect ego: “I can see how information X could lead you to that conclusion…”
  • 26. • Focus your arguments on the scientific consensus of man-made climate change i.e. the Green house effect, human CO2 emissions, rising CO2 levels, the Earth is warming, current climate change is CO2 driven • Climate sceptics often uses facts and statements that are true (but out of context or misunderstood) so start your response by agreeing. “You’re absolutely right”, “That is a really interesting point you raise” or “ a great question” • Avoid “”but no” or “that’s wrong” etc. • The longer you can use the language of agreement, the longer your counterpart will listen • Connect the abstracts of science to thinks people understand and use emotion
  • 27. Classic denial science arguments: 1. It’s been hotter and there’s been higher levels of carbon dioxide in the past 4.5 billion years; 2. They grew grapes in Newcastle; 2b. What about the medieval warm period? 2c. There are glaciers that are currently growing 2d. There are glaciers that have retreated in the recent past 3. The Earth is in an Ice age and is due to go into a period of cooling 4. Ice core records for the last 800,000 years show that temperature rises came before the carbon dioxide rises. Doesn’t this disprove the theory of climate change? 5. It’s natural not humans 6. Scientists use computer models which are inaccurate or speculative 7. Climate change is a scam that scientists are encouraging so they get funding 8. We need CO2 to feed plants so it is good for the earth 9. If water vapour is a greenhouse gas, why are we not worried about? 10. Climate change is just a theory 11. There’s nothing we can do about it 12. The idea that climate change is a serious threat to humans is an exaggeration
  • 28. 1. The Earth has indeed been much hotter with higher levels of carbon dioxide in the past 4.5 billion years and life can thrive as long it has had millions of years to adapt through evolution. The speed of the changes being experienced now are unprecedented and it is this speed and the inability of humans and the natural word to respond that makes our current situation so dangerous 2. All of the changes referenced are local or regional temperatures. What matters is the overall global average (mean) 3. The Earth is indeed in an ice age and until humans started releasing huge amounts of CO2 at a rapid rate, we would have expected orbital cycles to take us out into a phase of cooling over the next 50,000 years. These orbital cycles have now been overridden by the large increase in CO2 emissions. The last time there was this much CO2 in the atmosphere, the north pole was ice free 4. During the last 2.6 million years, the levels of atmospheric CO2 have been very low and we have been in an ice age. This has allowed cycles in the Earth’s orbit and tilt to be the primary driver of temperature changes instead of greenhouse gases. Each time orbital cycles pushed the earth into a warming phase, soils and melting ice released CO2, which then amplified the warming triggered by the orbital cycles. And this is why warming has begun prior to CO2 rises during the Quaternary Ice Age. Responses to These Arguments
  • 29. 5. Solar patterns, ocean currents, orbital (Milankovitch) cycles, cloud cover and albedo effect have all had their effects measured and can be ruled out conclusively. Aside from rising global temperatures, warming: poles, nights and winters are characteristic of greenhouse warming. Shrinking thermosphere, cooling stratosphere and measured spectral characteristics of energy reflecting back into space, are all specifically characteristic of greenhouse warming 6. Climate models are built from everything we know about the mechanisms that control the Earth’s climate. They can be tested by running them over periods in the past to see if they accurately match the records we hold over that time period. The predictions they are making have been broadly accurate and if anything they have underpredicted the effects of rising CO2 levels 7. Concerns about human emissions have been around since Victorian times, climate science is funded by a variety of sources all around the world, the science has been done by hundreds of thousands of scientists from every country in the world, oil companies have more of a motive to distort the evidence, oil companies themselves privately acknowledged the science as far back as the 1950s, the evidence is thorough 8. There is plenty of CO2 for plants, just because a substance has positive uses, doesn’t mean that it can’t have negative properties, we only want to prevent adding extra greenhouse gases to the atmosphere, not take away that which was already there prior to humans .
  • 30. 9. Water vapour is a condensable greenhouse gas. The Earth’s temperature poses a limit to how much water vapour the atmosphere can hold. Only if another factor (such as CO2) drives up temperatures can the amount of water vapour increase. When that happens it can then contribute to warming. Water vapour on its own cannot drive temperature change 10. When we say “theory” in an everyday sense we imply an idea or guess. A scientific theory is an idea that can be and has been tested to be true. Scientific theories underpin much of the modern world and are trusted without question. When a new means of testing them arises, scientists will do so 11. It is true that a certain amount of warming is on its way due to greenhouse gases already emitted. Scientists believe humans can reasonably adapt to 1.5 °C. Rises above this threshold will pose a serious threat to our economies, societies and civilisation. Scientists, economists, many policy makers and social scientists have told us that we can prevent climate change. The legislation, policy, taxation, funding and technological changes needed are all clearly understood, beneficial and much cheaper than inaction. Climate change dangerous to human civilisation will only happen if we choose not to act, rather than in all scenarios 12. Scientists have been careful to give conservative and well evidenced information to policy makers. Their conclusions are some of the most thoroughly examined investigations that there have ever been. What is in fact becoming clear is that rather than exaggerate, scientists conclusions have transpired to have significantly understated/underpredicted Earth’s sensitivity to greenhouse gases and that dangerous climate change is coming faster and more severely than was previously thought. Work done by scientists and academics have shown that human civilisation is very sensitive and vulnerable to climatic changes. The more complex the civilisation the more sensitive it becomes

  • 32. Talking with People About Climate Change
  • 33. Who might we be talking to about the Climate Crisis (Think situations, relationship etc)? What are the challenges and benefits of these different settings?
  • 34. Reasons/arguments for not acting on climate change There’s nothing I can do about it It’s not happening It’s natural or beyond our control It’s already too late Climate change is a scam Don’t want to give up lifestyle or technology Not interested Too stressed, poor or busy China aren’t doing anything Discuss in Groups
  • 35. Exercise: the Polar Bear Problem The imagery of environmentalism has been so long focused on pictures of sad animals that it has been attacked for over sentimentality and failure to connect to the human catastrophe of the climate crisis In groups make a list of: 1. the issues that people prioritise in their day to day lives? 2. Things that make up a person’s identitiy How will climate change impact on these things?
  • 36. What factors make a good conversation? What factors make a bad conversation? In pairs, share a climate conversation that went well and then one that did not go so well
  • 37. • Did you both listen to each other’s points? (ensure that you listen to the other person) • Was it a good time for you both to talk? • Did you use positive or negative language • Were either of you feeling tired, ill, hungry, sad, stressed, rushed, angry? • Was there a positive outcome? • Did you connect/bond with the other person? • Did you lean towards agreement or disagreement • Did you learn about each other? • Did one person talk a lot more than the other? • Did both people get to express their views and opinions? • Did both parties get something out of the discussion? • How did you feel at the end of a conversation? • Did the conversation result in positive change?
  • 38. A bad time to talk: Reasons why we might not start a climate conversation
  • 39. • Are you feeling, happy, confident, physically well and refreshed? • Is the person in a rush or angry? (annoying somebody won’t usually encourage you to take on board what you are saying) • Is a person tired or unwell? • Is it a good time of day (too early in the morning or late at night)? • Is this a person you feel able to connect with effectively (think gender, social, cultural issues etc)? • How important is it to talk to this particular person? Are you choosing the right battle? • Is there a difficult relationship or bad history between you and this person. Are you the right person to talk to this person? • Do you feel safe? • Is the setting or environment right to have this conversation? • A poorly timed or conducted conversation might do more harm than good to the climate cause
  • 40. What tips can help us to have an effective climate conversation?
  • 41. • Who is the person you are talking to? What matters to them? Show interest in them and learn about them • What do you have in common where can you connect as people and on the subject of the Climate Crisis • Listen to a person’s opinions. What do they think about the Climate Change or anything for that matter? • Don’t force the conversation straight to the climate crisis. Find out how the person’s day is and what they are up to? • Don’t attack, judge or blame. Start with what the person is doing right. Put emphasis on where you agree • Smile, share humour, compliment, focus on making sure that person is enjoying your interaction • Mirror body language and tone of voice, but be mindful of body language, personal space and eye contact
  • 42. • Be humble, peaceful and apologetic as required, especially if your are disrupting somebody’s life • Use “I” statements, share emotion and speak from the heart • As a protester of activist, just having a positive interaction is good. Later on they will remember a positive image to counter any media or public criticism
  • 43. The Bottom Line: As activists we need to create positive experience for individuals we interact with through listening, empathy and our constructive behaviour
  • 44. • Avoid Blaming • Holocracy • Post consensus • Non-violence • Civil disobedience • Sacrifice • We only need 3.5% In your groups can you make one or two points, views, justifications or scenarios that relate to having climate conversations and one of these key concepts and approaches
  • 47. Meaning: The risk and danger of climate change has been have been exaggerated for financial or other gain of as a sort of conspiracy theory Responses: • The scientists clear: this is the biggest threat to face our species this century • This isn’t a crank theory, least 97% of scientists agree • Yes I’m alarmed and for good reason • If anything, scientific reports have chronically understated the problem. Current climate change is decades in front of what the most pessimistic projections were predicting • Alarmism is a concept that spread to to try and attack the climate movement by weaponizing the truth and turning it back on them • We have a duty and need to tell the truth even if it is hard to hear
  • 48. Imagine in World War Two if: “Prime Minister Churchill! The Nazis are planning to start a war in Europe!” “Come on now. Don’t be so alarmist.”
  • 49. Doom mongering makes people feel powerless and scaring people doesn’t work! • We’re not doomed, we just need to act • There is nothing inevitable about the Climate Crisis • We have to tell the truth and this is very serious • People do respond positively and quickly to serious emergency situations • Fear and anxiety are powerful human emotions that evolved to motivate us into action • Shocking and scary images and information has been used in all kinds of public information campaigns • “Doom Monger” is a way of turning the truth into a criticism, paralysing an effective strategy • Extinction Rebellion has proved that stark messaging is very effective • Don’t stop scaring people, remove the reason for them to be scared
  • 50. Imagine in World War Two if: “Prime Minister Churchill! The Nazis will take over our country if we don’t do something!” “Come on now. Stop scaring people.”
  • 51. Going low carbon will damage our economy The cost of climate inaction will be greater than any other economic cost humans have ever incurred No cost is too great when the lives and wellbeing of billions of people and our future civilisation are at risk The transition to a low carbon economy will create many millions of jobs and generate trillions of dollars in savings in health and security It is wrong to pay for our prosperity with the lives of our children and future civilisation There is no economic argument for inaction or acting too slowly There are no jobs on a dead planet
  • 52. Imagine in World War Two if: “Prime Minister Churchill! The Nazis will take over our country if we don’t do something!” “I’m sorry but a war economy will cost too many jobs.”
  • 53. The climate movement is white and middle class • It is appalling that austerity, poverty and zero hours contracts have left so many people on the breadline that they have not the time or resources to explore or express their views about the future of their planet • Many minority groups still don’t feel safe to protest as they are still treated differently o perceive so, by the police • As a person of privilege, I am going to protest on behalf of those who are unable to or feel unsafe to do so
  • 54. Climate protesters tactics are causing disruption to peoples’ lives
  • 55. • The disruption caused by climate change will be millions of times greater. Billions will die, Billions more will be displaced or impoverished • It is tragic that 31 years (1988) after scientists warned the world of the threat that human greenhouse gas emissions posed to our civilisation and the natural world, and after letters, petitions, marches and lobbying, that successive governments has allowed us to come to the final threshold of the point of dangerous climate change and failed to act. It is therefore tragic that frightened and concerned law abiding citizens have been forced to use peaceful civil disobedience in order to safeguard the future wellbeing of their children. • The tactic of civil disobedience has been used many times to bring about positive change • In Britain there has always been an acceptance that doctors, nurses and teachers can go on strike and cause economic disruption and even personal suffering to secure better working conditions or pay
  • 56. Climate activists are radicals, extremeists and Anarchists Extinction rebellion are extremists, radicals and anarchists XR protesters are peace organisation assembled of people from all ages and all social spectrum most of who have never had any dealings with the law Peaceful civil disobedience is legitimate tactic used by many groups who have been remembered kindly and vindicated by the history books The most extremist behaviour on this planet right now comes from the rich minority who are putting the lives and wellbeing of billions and the future of our civilisation at risk, just so they can get rich
  • 57. In the face of the death of billions, the displacement of billions, social and economic global collapse and the loss of most of the species on Earth, driven by greed and consumption of a small minority, what could be more understated than a pink boat and a few thousand protesters in one city for a week
  • 58. What about China? They are much worse than us • We live in the UK we must focus on our emissions • The UK’s historical emissions and emissions per capita (when offshore emissions are included) are both higher than Chinas • A third of Chinese emissions are from the production of goods consumed in other countries • It is a good thing that in the UK we have the freedom protest without fear of repression about an issue of such magnitude
  • 59. But humans are so insignificant. How Arrogant to believe we could change the world so much!
  • 60. The HIV Needle Experiment… So Climate sceptics tell us we are so arrogant for believing that something as small an insignificant could have such a big affect on something as vast as Earth. Let’s just see whether they really do believe that logic… The difference in scale between a virus and a human is greater than that between a human and the Earth. How would you feel with this little needle of teeny tiny HIV viruses?
  • 61. The Shotgun Experiment… Some people use the following statement to justify inaction: “I don’t care what happens to humans. Just as long as the Earth survives.” Let’s test how much they really believe this opinion What would happen if you put a loaded shotgun to their head?
  • 62. The shackles of soft denial: how arguments from the right have been forced upon the climate movement • People are turned off by doom/alarm/danger • People feel powerless and feel unable to act • Everybody knows climate change is a problem • People can’t connect to problems that are distant • The climate movement is too negative and problem focused By repeating these arguments of those who have ideological and financial interest in the hydrocarbon industry, we are doing their work for them! The more these things are repeated, the more we make them true The truth has been turned into a weapon used to attack the climate movement
  • 63. People can’t connect to things that are distant to them
  • 64. We don’t have to be popular We just have to win Civil disobedience does not always breed popularity. In the US, the civil rights movement was vilified by many people and only history vindicated the many who languished in jails. Scientific truth is on the side of Extinction Rebellion. Be brave and keep going.
  • 65. Tackling formal debates on climate change There may be times where you will be called to formally debate or argue your position on the climate crisis either in an interview, in court, in a university or conference. How do you approach such a situation?
  • 66. Rule number one: know your shit. Stay in control of your emotions If you don’t know, say so
  • 67. Exercise: arguing against human-caused climate change Being able to express your views with confidence and clarity is critically important so in groups Prepare convincing arguments to advocate one of the positions below. Use any information you have read or heard and be persuasive and confident to convince us of your position. Use your phones to do some research. 1. The Earth isn’t warming 2. The current warming is part of a natural cycle 3. There are too many uncertainties in the science to say humans are causing the warming 4. Climate change science is being skewed by scientists who want to get funding 5. The climate movement is alarmist misrepresenting the science
  • 68. Argument Tactics and Strategies • Start a counter argument by agreeing with a part of what the other person has just said • Acknowledge a good point or argument before breaking it down or re-contextualising it • Adopt their language and terminology and use it to form your counter arguments • Own critiques of your arguments/position and turn them around- bring them up first • Find common ground and point it out where possible • Make somebody feel good about themselves, feed their ego • Build your counter arguments from the things they said and premises they use • Mirror their body language and tone
  • 69. • Avoid anger or aggression and point out that use of personal language or anger is the sign is a sign of a weak argument- If an argument is valid it will be so with reason only • If your opponent gets angry or aggressive, wind down the conversation or diffuse before continuing the discussion • “Know thine enemy”-research the arguments against your position well • Practice arguing against your own position • Show/indicate to the other person that you appreciate the discussion, conversation or discourse • Get the other person to agree to individual premises of your argument before presenting it in full • Disguise the final point to are planning to make in a given statement • Ask lots of clarifying questions
