PEEC program considers effects of climate change

-A A +A


Chick Keller will delve into the important topic of climate change and what to expect in the future. Keller will give an overview of recent research on climate change and then open up a discussion about how to deal with some of the issues. 

The program starts at 7 p.m. July 10 at PEEC and no advance registration is required.

With the recent latest release of the science of climate change by the Intergovernmental Panel on Climate Change (IPCC) and the Obama administration’s accompanying assessment for the United States, this is a good time to look at what is now known about how much warming and drying the world is likely to experience in the next 50 years. 

Considerable effort has gone into explaining the ‘hiatus’ in warming that has lasted at least 12 years. There have related studies that suggest the warming will be less than previously expected, but the exact amount is still under study. 

Climate models seem to be over estimating the sensitivity of climate to increases in so-called greenhouse gases, and they might not be capturing correctly either natural ocean variability or cloudiness and dust/aerosol cooling. 

Finally, there is considerable interest in the continuing rapid decline in Arctic sea ice and its possible effect on weather at lower northern latitudes.
