The melt rate of West Antarctica's Thwaites Glacier is an important concern, because this glacier alone is currently responsible for about 1 percent of global sea level rise. A new NASA study finds that Thwaites' ice loss will continue, but not quite as rapidly as previous studies have estimated.
The new study, published in the journal Geophysical Research Letters, finds that numerical models used in previous studies have overestimated how rapidly ocean water is able to melt the glacier from below, leading them to overestimate the glacier's total ice loss over the next 50 years by about 7 percent.
Despite what liberals may say about global warming, science is never a settled issue. That’s what you should glean from this. The studies can be wrong. The models can be wrong. And the question nations face concerning so-called global warming is whether they wan to invest hundreds of billion, if not trillions, of dollars on a group of people who have been wrong before. How much economic growth, decreased standard of living, less prosperity, and the accompanying misery will you artificially inflict among those in your society on predictions that have been grossly inaccurate? In the 1970s, global cooling was the threat that could spell mankind’s doom. Nothing ever happened.
Peter Gwynne has gone back and updated his 1975 Newsweek piece to deny climate change skeptics of using is as ammunition. Still, he had to change it because the science was wrong—and Gwynne admits that. He said that this field of study is always advancing. Yet, if you speak to these green warriors, the issue is settled. There is no more debate.
I beg to differ.
