Global warming:  See Greenland

Greenland. If you think it’s green, you would be wrong, for Greenland is basically one big sheet of ice. In fact, not only is it the world’s largest island, it’s ice sheet is the largest in the Arctic, it’s 2 miles thick in places.

Ninety-nine percent of the Arctic ice is locked up over Greenland. It’s basically one big glacier, fresh water ice that has accumulated its thickness during thousands of years of snowfall.

Greenland contains 10 percent of the world’s fresh water, as ice. Each summer, lakes of meltwater form on the ice sheet.

Over the past 20 years, these lakes have gotten larger and grown in number as the climate warms.

Meltwater from these lakes runs off in deep channels, which eventually dive deep down under the glacier through openings in crevasses. This water underneath the glacier acts as a lubricant, moving the glacier along toward the sea.

Greenland’s glacier is flowing seaward two times as quickly as it was 20 years ago. Since all this ice was once on land, upon reaching the sea, it causes the sea level to rise.

In 2010, 75 million tons of ice broke away from Greenland. By the end of the century, Greenland could add about 20 inches to the level of the sea, swamping many low-lying islands and atolls where people live, not to mention continental coastlines.

Marshall Islanders are already considering having to move. How does one move an entire country?

The cold meltwater will also interfere with the warm water currents, thus wreaking havoc with the climate and weather patterns, and the fresh water that has been locked up on land for ages will change the salinity of the sea, which will endanger sea life.

Meanwhile, our new government wants to end the EPA, and discard the minimum mileage limit on motor vehicles, has barred scientists from talking about global warming-climate change and wants to withdraw from the Paris Climate Accords. This is a recipe for disaster.

Please, help us mitigate climate change by eating little or no beef and conserving fossil fuels. And come to our Earth Day clean energy fair in the park in downtown Johnstown on Earth Day, April 22, from noon until 2 p.m.
