This Inside Climate News article discusses how Global Warming Is Changing the Winds Off Antarctica, Driving Ice Melt. A new study connects the dots between climate change and faster melting of the West Antarctic Ice Sheet, which has consequences for sea level rise. Westerly winds that enable warmer ocean water to creep beneath the floating edge of the ice sheet have become more prevalent over the past 100 years, scientists found in a new study, published Monday in the scientific journal Nature Geoscience.
This National Geographic article discusses how West Antarctica is melting—and it’s our fault. The fingerprints of human-caused climate change have made it to Antarctica, a new study (referenced above) shows. Now, a team has unraveled evidence of that human influence. In a study published Monday in Nature Geoscience, a team of scientists showed that over the past century, human-driven global warming has changed the character of the winds that blow over the ocean near some of the most fragile glaciers in West Antarctica. Sometimes, those winds have weakened or reversed, which in turn causes changes in the ocean water that laps up against the ice in a way that caused the glaciers to melt.
