October 2007 is Ninth Warmest on Record for Contiguous United States

Global Temperature Sixth Warmest on Record, as La Niña Continues

November 16, 2007

Temperatures in October 2007 were the ninth warmest on record for the contiguous U.S., and especially warm in the Northeast, where five states had their warmest October on record. The January-October 2007 U.S. temperature was the seventh warmest since national records began in 1895, according to scientists at NOAA’s National Climatic Data Center in Asheville, N.C. The global surface temperature was sixth warmest on record for October.

Precipitation was above average across the U.S., but not enough to quench the drought plaguing many parts of the country. At the end of October, 35 percent of the contiguous U.S. remained in moderate-to-exceptional drought, and unusually dry conditions contributed to destructive wildfires in southern California.

NOAA and other federal and state agencies have formed an expert drought group that has created an early warning system to detect drought and raise public awareness about why drought occurs and its affect on humans and nature, called the National Integrated Drought Information System. NIDIS was created in response to extended drought conditions over the past decade, with strong advocacy from the Western Governors Association and other groups.

The National Oceanic and Atmospheric Administration, an agency of the U.S. Commerce Department, is celebrating 200 years of science and service to the nation. From the establishment of the Survey of the Coast in 1807 by Thomas Jefferson to the formation of the Weather Bureau and the Commission of Fish and Fisheries in the 1870s, much of America's scientific heritage is rooted in NOAA.

NOAA is dedicated to enhancing economic security and national safety through the prediction and research of weather and climate-related events and information service delivery for transportation, and by providing environmental stewardship of our nation's coastal and marine resources. Through the emerging Global Earth Observation System of Systems (GEOSS), NOAA is working with its federal partners, more than 70 countries and the European Commission to develop a global monitoring network that is as integrated as the planet it observes, predicts and protects.
