In yet another sign that climate change is unstoppable key glaciers in Antarctica are reportedly beyond the point of no return. Their destruction means scientists will have to once again revise their projections upward for how high sea levels are likely to rise.
The glaciers, known as the West Antarctic Ice Sheet, would cause a 10 to 13 foot rise in sea levels if they all melted at once, but even smaller rises in sea level can have considerable effects on human life.
Sea level rise estimates are going to need to be revised upward: A portion of the West Antarctic Ice Sheet that is home to some of the fastest-flowing glaciers on the continent appears to have entered a state of retreat and melt that is “unstoppable,” two new studies have found.
“It has passed the point of no return,” said Eric Rignot, lead author on one of the studies and a glaciologist at the University of California, Irvine, and NASA’s Jet Propulsion Laboratory.
Given that the endless warnings by scientists and government agencies have been irrelevant in the face of fossil fuel industry power it is doubtful that this development in Antarctica will change much despite its significance.
Now that many of the trends are impossible to reverse the fossil fuel industry has shifted somewhat to acknowledge climate change exists but claim it can be overcome (presumably with their products and services).
It’s a brave new world.
