New Study: Carbon dioxide unlikely to cause rapid climate change

June 21, 2011

This new study  will surely roil the waters of the climate change debate in the coming days and weeks:

There have been instances in Earth history when average temperatures have changed rapidly, as much as 10 degrees Celsius (18 degrees Fahrenheit) over a few decades, and some have speculated the same could happen again as the atmosphere becomes overloaded with carbon dioxide.

New research lends support to evidence from numerous recent studies that suggest abrupt climate change appears to be the result of alterations in ocean circulation uniquely associated with ice ages.

“There might be other mechanisms by which greenhouse gases may cause an abrupt climate change, but we know of no such mechanism from the geological record,” said David Battisti, a University of Washington atmospheric sciences professor.

The research was done by an international team from Norway and the US and was supported by the US National Science Foundation and the Norwegian  Research Council.  It should be noted that this only addressed rapid climate change; greenhouse gasses are still responsible for slower, more subtle climate changes that are important to address.
