Gravity—yes, gravity—is the latest victim of climate change in Antarctica. That’s the stunning conclusion announced Friday by the European Space Agency. “The loss of ice from West Antarctica between 2009 and 2012 caused a dip in the gravity field over the region,” writes the ESA, whose GOCE satellite measured the change. Apparently, melting billions of tons of ice year after year has implications that would make even Isaac Newton blanch. Here’s the data visualized. It reminds me of those first images of the ozone hole, decades ago. To be fair, the change in gravity is very small. It’s not like you’ll float off into outer space on your next vacation to the Antarctic Peninsula. The biggest implication is the new measurements confirm global warming is changing the Antarctic in fundamental ways. Earlier this year, a separate team of scientists announced that major West Antarctic glaciers have begun an “unstoppable” “collapse,” committing global sea levels to a rise of several meters over the next few hundred years.
