Temperatures in September 2007 were the eighth warmest on record, hot enough to break 1,000 daily high records across the United States, according to scientists at NOAA’s National Climatic Data Center in Asheville, N.C.

The heat also helped spread the worsening drought to almost half of the contiguous U.S., with conditions across the Southeast, Mid-Atlantic and Tennessee Valley hardest hit. The global surface temperature was the fifth warmest on record for September, and the extent of Arctic Sea ice reached its lowest amount in September since satellite measurements began in 1979, shattering the previous record low set in 2005.

Global Highlights

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.
