Climate Doing Its Own Changing

A new peer-reviewed study claims that "[v]irtually all changes in global atmospheric temperatures in the late 20th century were the result of nature rather than human activity". 

Yeah, that "settled" science continues to get unsettled.

“It goes against the orthodoxy,” said climate scientist Chris de Freitas of New Zealand’s Auckland University. The new findings called into question the politically-correct, politically-motivated assumptions driving the climate change debate, he said.

De Freitas and Australian scientists John McLean and Bob Carter reported that at least 80 percent of climate variability tracked over the past half a century could be attributed to internal climate-system factors including the El Nino-Southern Oscillation (ENSO) Pacific warming phenomenon and its cooling twin, La Nina.

This left little room for human-caused factors like emissions of carbon dioxide (CO2) and other so-called greenhouse gases. Intermittent volcanic activity, producing significant cooling, was found to have been a factor.

The paper was published Thursday, following a six-month peer review process, in the American Geophysical Union’s Journal of Geophysical Research.

All of our efforts trying to stem this may be for naught.
