It was the most recent and longest interruption to the gradual warming of the Earth' s climate. Projections indicate that the considerable warming the Arctic is now experiencing due primarily to fossil fuel burning will completely melt this half- a- kilometer tall mountain of ice in just 200 to 500 years.

The Laurentide Ice Sheet was a massive sheet of ice that covered millions of square kilometers including most of Canada , a large portion of the northern United States multiple times during the Quaternary glacial epochs— from 2. 20, 000 years before the present.

The melting of the Cordilleran Ice Sheet likely caused around 20 feet sheet of sea level rise and big changes in ocean. Jul 20, · As so many of the predicted effects of climate change have failed to appear on time ( e. This confirms that once ice sheets start to melt, they can do so very quickly. This four sheet kilometer thick sheet formed about 2.
