"Urgent Action Needed to Save Greenland's Melting Ice Sheet, Researchers Warn"

New research suggests that the Greenland ice sheet is approaching a critical threshold that could trigger runaway melting, but there is still a chance to save it by limiting global warming to 1.5 degrees Celsius. Crossing the threshold temporarily would lead to significant sea level rise, but it may still be possible to stabilize the ice sheet if temperatures are reversed quickly. The size of the ice sheet provides humanity with some time to take action. However, world leaders are falling behind in their efforts to cut fossil fuel emissions, and the planet is on track to warm about 2.8 degrees Celsius by 2100. Despite this, even incremental reductions in greenhouse gas emissions remain crucial in mitigating the impacts of climate change. Sea level rise caused by the melting ice sheet will have severe consequences, including coastal erosion and flooding, emphasizing the urgency for immediate action.
