CLIMATE CHANGE: PERSPECTIVE,
SURPRISES, OPPORTUNITIES

• What is climate?
• Why does climate change?
• How fast does climate change?
• Have humans impacted climate?
• How small a change in climate is
important?
• Is recent climate change part of a
natural process or in a “new
state”?
• Where do we go next?
• What do we do next?

4pm: Dr. William Ruddiman
DID EARLY FARMING PREVENT
A NEW ICE AGE? THE ANSWER: YES!

• Greenhouse-gas trends in recent millennia differed
from those of previous interglaciations.
• Previously, they had always gone down; this time they
went up.
• These unexpected reversals in gas trends coincide
with the spread of agriculture.
• Conclusion: humans started interfering with (and
warming) climate thousands of years ago.
• Modeling experiments suggest these gas emissions
stopped the onset of a new ice age.
• CO2 levels then dropped significantly during the
cooling into the Little Ice Age (1200-1800 A.D.).
• Pandemics that killed tens of millions of people were
a major cause of these drops.
• As farmers died, forests reclaimed the land and took
up large amounts of CO2.
• So: pandemics were a significant factor in causing the
Little Ice Age.

7pm: Panel discussion with Drs.
Ruddimanand Mayewski moderated

THE TIGHTLY INTERLINKED
PROBLEM OF ENERGY

Energy is the fundamental limiting factor. Solutions to the energy-climate problem include: using less, greater efficiency, non-fossil sources, and (if carbon is sequestered) carbon-based
sources.
