Climate Indicators Agree that the Planet is Warming

Aug 4, 2010; 7:16 PM ET

Scientists from NOAA's National Climatic Data Center analyzed data on 37 climate indicators, but concentrated on ten indicators that the study says are especially revealing, according to the National Geographic article.

The ten indicators

--Humidity

--Sea-surface temperature

--Sea ice cover

--Snow cover

--Glacier cover

--Ocean heat content

--Lower atmospheric air temperature

--Sea level

--Temperature over land

--Temperature over oceans

All ten indicators point to a marked warming over the past three decades, with the most recent decade being the hottest. Records were kept since the 1880's.

This is the first time scientists have put data from climate indicators together in one place, according to the article.

The NOAA report which was published in the American Meteorological Society (AMS) is different from other climate publications, because it is based on observed data, not computer models.

"It's telling us what's going on in the real world, rather than the imaginary world," said Kevin Trenberth, a senior scientist at the Boulder, Colorado-based National Center for Atmospheric Research.

And even with real-world data, "the theory with regard to global warming is still incomplete"--especially since the atmosphere is so complex, Trenberth cautioned.
