Hangouts On Air October 10, 2012, to Discuss Climate Insights from Geologic Data:

Hangouts On Air to discuss the role of geologic data in climate research following the recent publication of our paper in the journal Science, in which we use geologic data to assess hypotheses about past climate change in western North America. What do geologic data tell us about climate change during Earth's history? How do scientists use geologic data to test the reliability of climate models? Can geologic data be used to gain insights about possible future climate change?

Here is a summary of the paper:

We analyze geologic data from the land and ocean to try to understand what formed the large lakes that extended across the Great Basin of western North America at the end of the last ice age. We find that the geologic data are consistent with a tropical source for the moisture, suggesting that the lakes were maintained by enhanced storms from the tropical Pacific and/or the Gulf of Mexico. This work is an example of how scientists use geologic observations to understand climate changes that have occurred during Earth's history.
