Michael Bastasch of the Daily Caller highlights new research that’s bound to displease climate alarmists.

New research suggests scientists may be wrong about a key measurement for projecting man-made global warming.

Meteorologist Anthony Watts and amateur scientist Willis Eschenbach released new research suggesting “global climate sensitivity to increased carbon dioxide, and the potential feedback mechanism of increased water vapor in Earth’s atmosphere, is actually far less than postulated by the IPCC.”

Watts and Eschenbach used satellite data to quantify the increased feedback from water vapor in the atmosphere. They found forcing water vapor since 1988 was greater than “all the other IPCC-listed forcing since 1750.”

That’s not all. The increase in downwelling radiation from water vapor since 1988 comes in addition to the climate forcings listed by the Intergovernmental Panel on Climate Change (IPCC) and little change in global average temperature in the last 15 to 20 years.

All of which “calls into question the applicability of the concept of ‘climate sensitivity,’” Watts and Eschenbach wrote, targeting the key input for climate models projecting future warming. Watts and Eschenbach are presenting new findings at the American Geophysical Union’s meeting in San Francisco. …

“This study was entirely serendipitous, the result came about from pure curiosity, nothing else,” Watts told The Daily Caller News Foundation.

“I’m hopeful others will download the data and code we provided, so that they can replicate the work, because replication is the best indicator of a ground truth in science,” he said.
