Greenland May Be Slip-Sliding Away Due to Surface Lake Melting

Summary:
A new study by the University of Colorado Boulder-based Cooperative Institute for Research in Environmental Sciences suggest that the Greenland Ice Sheet may be sliding at a faster rate into the ocean due to large releases of melt water from surface lakes.  Such an event like this affects the rising sea water level.  Scientists say this is the first time these findings have been discovered.  During the summer, the melt water rate is much higher. What happens is when enough water pressure builds up, the ice underneath the lake breaks creating an area for water to run into.  Over a ten year period, researchers used satellite images to monitor over 1,000 lakes.  They found that as the climate warms the rate for lake drainages increases.   This would increase the sea level rise related to climate change.  This phenomena may also have some positive effects.  By the water draining out into a fixed area, it would create an efficient way to route water to the ocean.  This would also slow down the ice sheet's migration into the ocean and decelerate sea-level rise.

Critique:
I think this is very interesting, it shows just one of the millions of effects global warming has on our planet.

Impact:
Hopefully this will show people what an issue global warming is and that we need to take action in order to save our planet.
