By Deborah Zabarenko, Environment Correspondent WASHINGTON (Reuters) - Climate policymakers and scientists need to look beyond global warming emissions of carbon dioxide and take the loss of stratospheric ozone into account, researchers said on Thursday.

The keys to understanding future climate change may be locked in rocks and sediments that act as records of conditions millions or billions of years ago, the National Academy of Sciences said yesterday.
