GLOBAL WARMING IS A HUGE ISSUE AND ITS NOT A LOCAL PROBLEM , NOT A NATIONAL ISSUE BUT ITS A GLOBAL ISSUE AND HAS AFFECTED THE CLIMATE OF THIS WORLD.
BE CAREFUL!
2. The Main Culprits For Global Warming
Water Vapour (H2O)
Carbon Dioxide (CO2)
Methane (CH4)
Ozone (O3)
3. Some Facts
• Human population x 4 in 100 years
• It took 10000 generations of human beings to
reach 2 B
• We have tripled that in less that one lifetime
4. Temperature goes up melting ice caps
• Before the warming:
Kilimanjaro, 1970
• After the warming:
Kilimanjaro, 2000
5. Temperature goes up melting ice caps
• Before the warming: Nepal,
1978
•
After the warming: Nepal,
2004
6. Temperature goes up melting ice caps
• Even more obvious from
space, this pictures of the
North Polar cap from
NASA show a melting of
25% in 25 years:
7. Graphical Data
•
At the end of 2002, the concentration of carbon dioxide was just
above 370ppm.
•
This is probably the highest in at least 400,000 years
8. Graphical Data- Carbon Footprint
• Every country bears its share of responsibility, The USA
being number one.

9. Some Facts:• The number of category 4 and 5 hurricanes has almost
doubled in the last 30 years.
• Malaria has spread to higher altitudes in places like the
Colombian Andes, 7,000 feet above sea level.
• The flow of ice from glaciers in Greenland has more than
doubled over the past decade.
• At least 279 species of plants and animals are already
responding to global warming, moving closer to the poles.
10. The Consequences of sticking to ‘Business As
Usual”
• Global sea levels could rise by more than 20 feet with
the loss of shelf ice in Greenland and Antarctica,
devastating coastal areas worldwide.
• The arctic ocean could be ice free in summer by 2050.
• Heat waves will be more frequent and more intense.
• Droughts and wildfires will occur more often.
