(.#A.012).- Snow cannons against melting glaciers ? Snow cannons against melting glaciers ? Thursday, July 18, 2019. PARIS - (AFP) How to counter the thaw of West Antarctica and rising sea levels? Pumping the water from melting ice to reject it on the ice cap with snow cannons, suggests a study published yesterday. This area of Antarctica contains enough frozen water to raise the level of the planet's oceans by about six meters. A mere one-meter rise would force 190 million people from their homes and a three-meter increase would jeopardize megacities like New York, Shanghai and Tokyo. CRUCIAL POINT Scientists are particularly concerned that the Pine Island and Thwaites glaciers - which contain enough ice to raise sea levels by three meters - have reached a point of no return where they would continue to melt. While limiting global warming may not be enough to avoid disasters, different technological approaches are being considered. Researchers have therefore devised this pumping solution for melted ice to project it onto the ice cap. "It's a terrible thing to do (...) and we do not suggest doing it at all costs," says a physicist at the Potsdam Institute for Climate Impact Research and author of the study in Science Advances.
