"Pesquisadores do Instituto Geofísico da Universidade de Texas–Austin (UTA’s Institute for Geophysics), concluíram que a diminuição das geleiras na Antártica Ocidental se deve ao calor geotermal gerado pelos abundantes vulcões da região. E nada tem a ver com o aquecimento global." Blog
Antarctica is a land of ice. But dive below the West Antarctic Ice Sheet, and you'll find fire as well, in the form of subglacial volcanoes.
Now, a new study finds that these subglacial volcanoes and other geothermal "hotspots" are contributing to the melting of Thwaites Glacier, a major river of ice that flows into Antarctica's Pine Island Bay. Areas of the glacier that sit near geologic features thought to be volcanic are melting faster than regions farther away from hotspots, said Dustin Schroeder, the study's lead author and a geophysicist at the University of Texas at Austin.
