Despite Cooling Temperatures and More Sea Ice in Antarctica the Gang Green still Claims Global Warming

Timothy Birdnow

Here are two stories about Antarctic ice that expose the lie of the Global Warming alarmism. First, it turns out even the Antarctic Peninsula is not warming:

The Antarctic Peninsula, regarded as a "global warming hot spot”, has been cooling for almost 20 years.

Natural variability was responsible both for the decades-long warming since the 1950s and more recent cooling, according to research published today in Nature.

The research, led by John Turner from the British Antarctic Survey, said while the start of Antarctic Peninsula cooling in 1998 had coincided with the so-called "global warming hiatus”, the two were not connected.

Scientists were quick to declare the results of the Turner et al paper, which covered 1 per cent of the Antarctic continent, did not negate a long-term warming because of man-made climate change.

Rather, they said, the ozone hole, changing wind patterns and natural variability had masked the long-term warming trend.

"Climate model projections forced with medium emission scenarios indicate the emergence of a large anthropogenic regional warming signal, comparable in magnitude to the late-20th-­century peninsula warming, during the latter part of the current century,” the Turner research concluded.

In addition, temperatures on the Antarctic Peninsula remained higher than measured during the middle of the 20th century, so ­glaciers were still retreating in the Antarctic region.

Nonetheless, the findings have put into sharp relief the long-term cycles of natural variability in an area popularised in the climate change narrative by dramatic ­images of calving ice sheets and retreating glaciers.

Prior to the paper’s publication, science media organisations around the world were ready with quotes from climate scientists to ensure the Turner paper was not misinterpreted.

End exccerpt.

Meanwhile, the Science Establishment is quick to blame anthropogenic causes for any evidence of warming, such as sea ice melt, but even quicker to blame nature when the reverse is true:

"The study offers evidence that the negative phase of the Interdecadal Pacific Oscillation (IPO), which is characterized by cooler-than-average sea surface temperatures in the tropical eastern Pacific, has created favorable conditions for additional Antarctic sea ice growth since 2000.

The findings, published in the journal Nature Geoscience, may resolve a longstanding mystery: Why is Antarctic sea ice expanding when climate change is causing the world to warm?

EDITOR'S NOTE; THERE HAS BEEN NO WARMING IN 20 YEARS.

The study's authors also suggest that sea ice may begin to shrink as the IPO switches to a positive phase.

"The climate we experience during any given decade is some combination of naturally occurring variability and the planet's response to increasing greenhouse gases," said NCAR scientist Gerald Meehl, lead author of the study. "It's never all one or the other, but the combination, that is important to understand."

Study co-authors include Julie Arblaster of NCAR and Monash University in Australia, Cecilia Bitz of the University of Washington, Christine Chung of the Australian Bureau of Meteorology, and NCAR scientist Haiyan Teng. The study was funded by the U.S. Department of Energy and by the National Science Foundation, which sponsors NCAR
