Ocean Cooling

Not by Fire but by Ice

New data shows vast ocean cooling

17 Aug 06 - The world's oceans cooled suddenly between 2003 and 2005,
losing more than 20 percent of the “global-warming” heat they'd absorbed over 
the previous 50 years. That's a vast amount of heat, because the oceans hold
1,000 times as heat as the atmosphere. The researchers say the heat was likely
vented into space, since it hasn't been found stored anywhere on Earth. The
startling news of ocean cooling comes courtesy of the new ARGO ocean
temperature floats being distributed worldwide.

John Lyman, of NOAA’s Pacific Marine Environmental Laboratory, says the
discovery of the sudden ocean coolings undercuts faith in global-warming forecasts
because coolings randomly interrupt the trends laid out by the global circulation

Lyman says the sudden ocean coolings particularly complicate the problem of
separating natural temperature changes from man-made impacts on the Earth's
temperature. The impact of human-emitted CO2 has been assumed to accumulate
in a straight-line trend over many decades. Meanwhile, since the 1980s, the Earth's
ice cores, seabed sediments and cave stalagmites have revealed a moderate,
natural 1,500-year climate cycle linked to solar irradiance. Temperatures jump
suddenly and erratically 1 to 2 degrees C above the mean at the latitude of
Washington, D.C., and New York City for centuries at a time, and more than that
at the Earth's poles. 

What does this ocean cooling mean? I don't know yet. What I do know, is that it should prove beyond all reasonable doubt that the process of ocean warming/ocean cooling is not driven by humans.
