Pass the road salt.
In fact, 80 percent to 90 percent of global warming involves heating up ocean waters. They hold much more heat than the atmosphere can. So (Josh Willis at NASA's Jet Propulsion Laboratory) has been studying the ocean with a fleet of robotic instruments called the Argo system. The buoys can dive 3,000 feet down and measure ocean temperature. Since the system was fully deployed in 2003, it has recorded no warming of the global oceans.
"There has been a very slight cooling, but not anything really significant," Willis says.
