Tackling The Laurentide Ice Sheet in Greenland

The Laurentide Ice Sheet

When the great Laurentide Ice Sheet melted and dwindled into smaller caps, there were no scientists to analyze it!

This happened nearly 11,000 years ago and uncovered a major part of North America (the land we see today). The Laurentide Ice Sheet collapsed and spread across nations like Canada and Alaska. This raised the sea by several tens of feet. No one saw these changes as the Northern Hemisphere became warmer, leading to its irreversible status.

Recent Studies about Ice Sheets

Today, scientists are doing lots of studies on how the ice sheet covering Greenland is and will be in the future. These ice sheets survived when the Laurentide Ice Sheet failed. Scientists believe that there are many similarities between the ones that cover Greenland today and the Laurentide. This time, they are taking accurate measurements and looking for ways to make sure they don’t melt like before.

These studies proved the presence of a serious melting on the top surface of the ice. This ended up forming lakes and pools. Meanwhile, ice is melting and falling into open seas, daily. Glaciers that grow from the center are flowing into deep waters now. Yet, there is little data to reveal how quickly the melting would happen!

Very bad Condition!

Researchers suspect this to be very bad. That is because excess water drainage can result in overflowing local lakes and rivers. The volume of water in these lakes is likely to increase by 115 to 180 percent by the end of the next two decades.

Indeed, the rate of increase depends on the number of greenhouse gases released.

Lakes are likely to grow not in the southern regions, but in the northeast borders.

“This is where more remote ice sheets are likely to melt and advance in the years to come”, say researchers.
