A new method to assess the Nation's potential for storing carbon dioxide in rocks below the earth's surface could help lessen climate change impacts. The injection and storage of liquid carbon dioxide into subsurface rocks is known as geologic carbon sequestration. USGS scientist Robert Burruss discusses this new methodology and how it can help mitigate climate change. (5:44) | Transcript/Links | Download directly (5.25 MB) (right-click to save) |

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. (7:08) | Transcript/Links | Download directly (6.62 MB) (right-click to save) |
