Prehistoric Climate Provides Clues to Future Changes Quick look:
More accurate predictions of future climate and improved understanding of today’s warming are possible with new data from the first comprehensive reconstruction of an extreme warm period. Past warm periods provide real data on climate change and are natural laboratories for understanding the global climate system. USGS scientists Harry Dowsett and Marci Robinson discuss this research and implications.
