Climate Change May Magnify Toxic Chemical Dangers

A draft summary of the Intergovernmental Panel on Climate Change's latest report on the impacts of global warming does not address the added possibility that climate change could magnify the havoc wrought by long-lasting and pervasive toxic chemicals.

new study highlights how global warming may affect the movement and levels of chemicals such as organochlorine pesticides in the environment, as well as how a changing climate might weaken the ability of animals and humans to tolerate those chemicals.

The reverse is also addressed:  Greater chemical exposures could hamper a polar bear's or human baby's ability to handle extreme temperatures, severe storms, lack of food or other hazards of climate change.
