Mystery of the 'Missing' Global Warming
October 23, 2013 10:33 AM EDT
Have you heard the one about how global warming stopped in 1998? Its been called a pause, a hiatus, a slowdown and a siesta. Above all, its a red herring, and it isnt difficult to find where some of the missing heat has gone.
First, in case you havent been paying attention: 97 percent of climate scientists agree about global warming and its man-made causes, now with 95 percent certainty, according to a report this month by the IPCC, the worlds most authoritative body of climate scientists. Greenhouse gases trap heat, which melts ice, raises seas and floods cities; this fundamental equation is not in doubt.
What has raised a few eyebrows recently is that temperatures on the surface of Earth have increased at a slower rate since 1998 than in previous decades. Scientists have largely chalked this up to the short-term variability of climate. However, climate skeptics have taken the surface-temp slowdown acknowledged by the IPCC to mean that global warming itself has stopped -- that somehow the physics has changed.
It hasnt.

The warming at the oceans surface layer may have slowed a bit, but ocean temperatures in aggregate have continued to rise unchecked during the so-called hiatus, according to the IPCC. Thats important because while the atmosphere accounts for just 1 percent of planetary heat, the oceans carry 93% of the stored energy from climate change (melting ice and warming continents make up the rest).
In fact, there is mounting evidence that deeper regions of the ocean, down to 2000 meters, are absorbing heat faster than ever, Trenberth said in a phone call. His research shows the oceans began taking on significantly more heat at around the same time the surface warming began to slow in 1998. His widely cited work was published just after the cutoff to be included in the IPCC report.
The irony, says Trenberth, is that when the surface of the planet is unusually sweltering, the Earth actually radiates more heat into the atmosphere, in effect slowing the long-term warming of the planet. And in hiatus years, when the surface is cooler, the Earth absorbs more of the suns heat deep the oceans, slowly cooking the planet. What you see isn't always what you get.
Ocean temperatures are just one of many independent lines of evidence showing that climate change continues to speed ahead on an alarming course. Need more? Look to the seas that are rising faster than previously anticipated, the imbalance of energy measured entering and exiting the upper atmosphere, and the melting glaciers and permafrost. I could go on.
