New study shows worrisome signs for Greenland ice

Source: theguardian/17-Apr-2017
As humans put more heat-trapping gases into the atmosphere, like carbon dioxide, ice around the planet melts. This melting can be a problem, particularly if the melting ice starts its life on land. That’s because the melt water flows into the oceans, contributing to rising sea levels. Greenland ice is a great analogy for the Earth’s climate. It has inertia, meaning it acts slowly but once it gets going, it’s hard to stop. When the Greenland ice sheet starts to go, it may take a while to melt but it is nearly impossible to stop. Predicting how fast this melt will take is interesting from a scientific vantage point but there are also enormous social and economic consequences. Right now, 150 million people live within a meter (3 feet) of today’s sea level.
