Humans mostly caused 2006 record heat, NOAA says
Contributed by: Hank Lacey   on 8/30/2007

The National Oceanic and Atmospheric Administration, an agency of the U.S. Department of Commerce that conducts meteorological research, has concluded that about one-half of the record heat in 2006 was caused by human activities.

Based on preliminary data, 2006 was the warmest year in the 112-year record available for the lower 48 states.

NOAA's news release about the record left uncertain how much of the warmth was attributable to human-generated greenhouse gases and how much to other factors. 2006 was also a year in which the natural Pacific Ocean-based fluctuating weather event known as " El Nino" was active. The previous record year of 1998 was also an El Nino year.

"A timely science-based attribution statement is essential," the scientists wrote. "The question of climate change recently took center stage at both House and Senate hearings in which congressmen discussed their positions on how the Nation should address global warming. Policy and decision makers are requesting expert interpretation. They want to know why the climate is behaving as observed because such knowledge is a key input to informing their debates and responses."

The authors conclude that the record warmth in 2006 was caused mostly by human influence on the climate. By looking at observations and model assessments of the factors, they concluded that El Nino could not have been responsible for most of the warming and that human-generated greenhouse gases caused at least 50 percent of it.

They also concluded that 2007 offers a 16 percent chance of setting yet another record as the warmest in the U.S.

The research will be published in the September 5 issue of Geophysical Research Letters.
