Short-term weather fluctuations should not blind us from what long -term climate trends are telling us. Other unexpected aspects of complex system dynamics are the Butterfly Effect and the descendent benefit of epidemics.

•The intuitively obvious "solutions" to problems are wrong
(apt to fall into one of several traps set by the character of
complex systems.)
•Cause and effect are not closely related in time or space.
•Action is often ineffective because symptoms are treated,
not the problem.
-The cause of the problem is within the system.
•Conflicts arise between short-term and long-term goals.

3. BUTTERFLY EFFECT:
Precision in Initial Conditions Limits Weather
Predictability
MIT Prof Edward
Lorentz
1961

6. The Lorenz Attractor: wibbly-wobbly mess of the millenium. Three
simulation runs (red, green, blue) are shown; they start close together
but quickly spin off on different trajectories, demonstrating sensitivity
to initial conditions (weather).
Nonetheless, the trajectories quickly converge on an intricate
structure in the phase space, called an 'attractor'. The attractor
doesn't vary with initial conditions, but is instead a feature of the
Lorenz equations themselves (climate).

7. Long term stable attractor pattern looks like butterfly wings

8. Did chaos theory kill climatology ?
“Climate in a narrow sense is usually defined
as the average weather, or more rigorously,
as the statistical description in terms of the
mean and variability of relevant quantities
over a period of time ranging from months to
thousands or millions of years.” IPCC
NO! LONG TERM AVERAGES ARE PREDICTABLE

9. 1880-1980: 0.3 C TEMP INCREASE
1980- 2012: 0.55 TEMPERATURE INCREASE
(Hansen, J., Ruedy, R., Sato, M., and Lo, K., 2010: Global surface temperature change, Rev. Geophys. 48, RG4004.)
LONG TERM AVERAGES REMOVE THE SHORT TERM FLUCTUATIONS

10. CORRELTAION BETWEEN TEMP AND CO2 INCREASE. IS THERE A PHYSICAL
PROCESS LINKING TEMPERATURE INCREASE TO THAT OF GREENHOUSE GAS CO2?

11. Increasing CO2 gas density: 1. raises temperature of earth’s surface.
2. reduces temperature of the stratosphere.

12. WEATHER VS. CLIMATE
•Initial condition accuracy limits weather
predictions to days. After this predictions
become chaotic.
•Long term averages smooth out chaotic
fluctuations. Equivalently the “attractor” is
independent of initial conditions.
•Long term climactic averages aided by
physical understanding can be predictable.
•Similar to quantum theory of particles.

Weather Channel, said

is not rising significantly. The polar ice is increasing, not
melting away.

perspective?

14. • The Sept 2012 minimum area set a record low.
• Sept 2013, 2014 is larger but not climate trend changing.

Sea level rise is a proxy for

it is due to thermal

26. PAST COLD ARCTIC PRESENT WARMER ARCTIC
Higher pressure sub-tropic constrained the
low-pressure arctic
Lower pressure difference allows
waves of arctic air to invade the
South: Warmer & Colder Winters.
Cold Air Oscillates South from the Arctic
The Arctic is warming faster than the rest of our earth.
Therefore the temperature and the accompanying pressure difference that used to keep
arctic air up North comes South, bringing cold air to Atlanta & New Orleans.

27. The jet stream that circles Earth's north pole travels west to east. But when the jet stream
interacts with a Rossby wave, as shown here, the winds can wander far north and south,
bringing frigid air to normally mild southern states. http://www.npr.org/blogs/thetwo-

33. THE LONG TERM BENEFICIARIES OF SHORT TERM DISASTERS
THE BRIGHT SIDE OF THE BACK DEATH
The Bubonic Plague left its mark on the human population of Europe,
showing that what doesn’t kill you makes you stronger.
American Scientist vol. 102, pg 410-413, Nov-Dec 2014

34. Population dropped precipitously by a factor of 2 in 1348.
However, population had trippled from 1100 to 1300.

35. DESCENDENT BENEFITS
•Sharon DeWitte by examining cemeteries:
-A higher proportion of the population reached older ages
after the Black Death than before.
•Wages of labor rose due to higher demand.
•More land, food, and money for ordinary people.
• After 1492, Native American population plummeted
because they were not immune to European diseases.
-Advantage to European settlers in armed conflicts.

36. LONG TERM DESCENDENT BENEFITS
“God judged it better to bring
good out of evil, than to suffer no
evil to exist.”
Thomas Aquinas (1225–1274)

•Long term averages smooth out chaotic
