David Archer, Ph.D. - University of Chicago
Using results from models of the atmosphere/ocean/sediment carbon cycle,
the impacts of fossil-fuel CO2 release will be examined including the
effect on climate many thousands of years into the future, rather than
for just a few centuries as commonly claimed. Prof. Archer will explain
how aspects of the Earth system, such as the growth or melting of the
great ice sheets, the thawing of permafrost, and the release of methane
from the methane hydrate deposits in the deep ocean, take thousands of
years to respond to a change in climate. The duration of our potential
climate adventure is comparable to the pacing of climate changes in the
past, which enables us to use the geologic record of ...

In 2005, coral reefs across the Caribbean were damaged by a massive
bleaching event. This occurs when water becomes too warm for coral, and
they expel their colourful algae. A Canadian climate
scientist at the Woodrow Wilson School of Public and International
Affairs at Princeton University, Dr. Simon Donner, is trying to understand how greenhouse
gases might be implicated in such events. He's found that weather
leading to coral-destroying bleaching is ten times more likely with
current greenhouse gas levels, and such events will become far more
frequent in future climate scenarios.

This week, the report of the Intergovernmental Panel on Climate Change,
Working Group II, was issued. Unlike Working Group I, which focused on
the mechanisms of climate change, this report looks at how climate
change is affecting our planet right now. Ice is disappearing earlier in
the spring, trees are budding earlier, and extreme weather events are
causing more outbreaks of disease, than 20 years ago. This report
summarizes the latest in effects of climate change, as well as offering
suggestions for ways to adapt to the changes. Linda Mortsch is a Senior
Researcher with the Adaptation and Impacts Research Division of
Environment Canada, and was the lead author for the North American
chapter of the report.
