Global Warming, No … Little Ice Age, No … Climate Change?

NPR, hardly the bastion of the anti-global warming crowd had the following article.  Now it could be a case of we don’t know what we don’t know; but it seems we should find out more before we spend billions to try to change what we don’t understand

The Mystery of Global Warming’s Missing Heat

  Some 3,000 scientific robots that are plying the ocean have sent home a puzzling message. These diving instruments suggest that the oceans have not warmed up at all over the past four or five years. That could mean global warming has taken a breather. Or it could mean scientists aren’t quite understanding what their robots are telling them.

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 Willis 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. So the buildup of heat on Earth may be on a brief hiatus. “Global warming doesn’t mean every year will be warmer than the last. And it may be that we are in a period of less rapid warming.”
