Temperature change in the Arctic is happening at a greater rate than other places in the Northern Hemisphere, and this is expected to continue in the future. As a result, glacier and ice-sheet melting, sea-ice retreat, coastal erosion and sea level rise can be expected to continue. USGS scientist Joan Fitzpatrick discusses a new report on past climate variability and change in the Arctic. (11:15) | Transcript/Links | Download directly (10.38 MB) (right-click to save) |

Today, the USGS released the first publicly available petroleum resource estimate of the entire area north of the Arctic Circle. This area has an estimated 90 billion barrels of undiscovered, technically recoverable oil, 1,670 trillion cubic feet of technically recoverable natural gas, and 44 billion barrels of technically recoverable natural gas liquids in 25 geologically defined areas thought to have potential for petroleum.

Sea ice, which is constantly thickening and thinning, plays an important role in the Earth's climate system. We sit down with USGS scientist Dave Douglas to discuss a newly developed modeling approach to estimate sea ice thickness—this is the only model based entirely on historic observations, and it was developed by scientists from the USGS and the Russian Academy of Sciences in Moscow.
