As July continues to sizzle in much of the United States, a new U.S. report says the 2000-2009 decade was the Earth's warmest on record and "global warming is undeniable."

About 300 scientists from 48 countries contributed to the 2009 State of the Climate report (http://www.noaanews.noaa.gov/stories2010/20100728_stateoftheclimate.html) released Wednesday by the National Oceanic and Atmospheric Administration.
The report focused on 10 indicators of a warming world, seven which are increasing and three declining. Rising over the decades are average air temperature, the ratio of water vapor to air, ocean heat content, sea-surface temperature, sea level, air temperature over the ocean and air temperature over land.
Indicators that are declining are snow cover, glaciers and sea ice.
"The temperature increase of one degree Fahrenheit over the past 50 years may seem small, but it has already altered our planet," said Deke Arndt, co-editor of the report and chief of the Climate Monitoring Branch of the data center.
"Glaciers and sea ice are melting, heavy rainfall is intensifying and heat waves are more common," he says.
Last month was the warmest June on record and this year has had the warmest average temperature for January-June since record keeping began, NOAA reported last week.
