A new study published recently in the journal Nature shows that indeed Antarctica is melting at a faster rate than previously thought. Bad news for coastal areas as the rate of melt has doubled since 2012. With a faster rate of melt one can expect that this will contribute 6 inches to the sea level rise by 2100, at the upper level of what had been previously estimated by various panels. This means that instead of Brooklyn being flooded once a year it would now be flooded 20 times a year. A real nuisance to the people living there I would assume.
Of course not only Antarctica is melting. Greenland is melting as well as it has lost an estimated 1 trillion tons of ice between 2011 and 2014. With oceans warming and their waters expanding this means that the sea levels will also rise.
With better satellites in orbit observing the polar regions we now can be very sure about things like rates of melting in such areas. The idea that as the climate warms this will increase precipitation and that this would also mean more ice at the poles was disproved by the new studies.
With the Trump administration advocating cuts to Earth observation programs we risk missing out on future details about rates of melt in the polar area and so endangering communities who live along the various coasts worldwide.
