In a new study published in the journal Nature, NASA scientists have found that Greenland's ice sheet is melting from below. The study, which was led by Michael Bevis, a professor of Earth system science at the University of California, Irvine, found that warm water from the Atlantic Ocean is seeping into the ice sheet through cracks and fissures, melting it from the inside out.
The researchers used satellite data to track the movement of the ice sheet and the temperature of the ocean water around Greenland. They found that the ice sheet is melting at a rate of about 100 cubic kilometers per year, and that the melting is concentrated in the southern part of the ice sheet, where the ocean water is warmest.
The researchers say that the melting of Greenland's ice sheet is a major contributor to sea level rise. They estimate that the ice sheet is currently contributing about 0.2 millimeters per year to sea level rise, and that this rate is expected to increase in the future.
The findings of the study are a major wake-up call for the world. They show that the melting of Greenland's ice sheet is happening much faster than previously thought, and that it is a major threat to coastal communities around the world.
The study also has implications for the global climate. The melting of Greenland's ice sheet will release large amounts of fresh water into the ocean, which could disrupt ocean currents and alter the climate.
The researchers say that more research is needed to understand the full extent of the melting of Greenland's ice sheet and its implications for the global climate. However, they say that the findings of the study are a clear indication that climate change is a serious threat to the planet.
