Study will anchor new IPCC climate change assessment
By Summit Voice
FRISCO — Just as thousand of delegates gather in Doha, Qatar for the UN’s annual climate talks, researchers are releasing a wealth of new observational data that verifies the output from existing climate models.
In recent example, a team of climate scientists from the Lawrence Livermore National Laboratory and colleagues from 16 other organizations compared simulations from 20 different computer models to satellite observations, finding that tropospheric and stratospheric temperature changes are clearly related to human activities.
“It’s very unlikely that purely natural causes can explain these distinctive patterns of temperature change,” said Lawrence Livemore National Laboratory atmospheric scientist Benjamin Santer, who is lead author of the paper appearing in the Nov. 29 online edition of the journal, Proceedings of the National Academy of Sciences. “No known mode of natural climate variability can cause sustained, global-scale warming of the troposphere and cooling of the lower stratosphere.” (more…)
