It’s hot. A number of North American cities have set record-high temperatures. But this is summer and that’s not indisputable evidence that man’s use of fossil fuels is overheating the planet. No matter what the Democrats say, how much the media nag, and how loudly zealots screech, the issue is not settled. There’s still enough doubt about the entire enterprise to fill the yawning gap between Earth and some far-away galaxy.
If climate models were on trial – and they should be – that doubt would be magnified by a new post from the Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado Boulder, which confirms “models may overestimate warming.”
“Today’s climate models are showing more warmth than their predecessors, forecasting an even hotter future for the same rise in atmospheric carbon dioxide. But a paper published this week highlights how models may err on the side of too much warming: Earth’s warming clouds cool the surface more than anticipated, the German-led team reported in Nature Climate Change,” says CIRES.
Jennifer Kay, a CIRES fellow and an associate professor of atmospheric and oceanic sciences at Colorado University, says “the increase in climate sensitivity from the last generation of climate models should be taken with a huge grain of salt.”
