Study: West Antarctic Glacier Melt Due To Volcanoes, Not Global Warming

Previous studies have also shown that the collapse of the continent’s western ice sheet is nothing new. The British Antarctic Survey (BAS) has released two major studies in the last year showing that the thinning south pole ice is nothing new.

A BAS study from February found that Antarctica’s Pine Island glacier thinned just as fast 8,000 years ago as it has in recent times — it also was able to reverse the collapse.

Another BAS study from last year says western Antarctic thinning is within the “natural range of climate variability” of the last 300 years.

“The record shows that this region has warmed since the late 1950s, at a similar magnitude to that observed in the Antarctic Peninsula and central West Antarctica,” said a BAS study published in the journal Geophysical Research Letters last year, “however, this warming trend is not unique.”

“More dramatic isotopic warming (and cooling) trends occurred in the mid-19th and 18th centuries, suggesting that at present the effect of anthropogenic climate drivers at this location has not exceeded the natural range of climate variability in the context of the past ~300 years,” the study said.
