====The Arctic and other high latitude areas (SAP 1.2)====
On January 16, 2009 (the last business day of the Bush Administration), USGS released ''Past Climate Variability and Change in the Arctic and at High Latitudes''.<ref>[http://www.climatescience.gov/Library/sap/sap1-2/default.php CCSP, 2009.] {{webarchive|url=https://web.archive.org/web/20090706025403/http://www.climatescience.gov/Library/sap/sap1-2/default.php |date=2009-07-06 }} Past Climate Variability and Change in the Arctic and at High Latitudes. Alley R.B., [[Julie Brigham-Grette|Brigham-Grette J.]], Miller G.H., Polyak L., and White J.W.C. U.S. Geological Survey, Washington, DC. 270 pp.</ref> According to the USGS press release,<ref>[http://www.usgs.gov/newsroom/article.asp?ID=2109&from=rss_home U.S. Geological Survey, Office of Communication] Arctic Heats Up More than Other Places, January 16, 2009</ref> the report shows that:
* The Arctic has recently been warming about as rapidly as it has ever warned throughout the entire record of past Arctic climate.
* The loss of sea ice during summers over the last few decades is highly unusual compared to the last few thousand years. Changes in Earth's orbit alone would have increased summer sea ice.
