600 Billion Tons of Ice Melted in Greenland in 1 Year, Increasing Even Faster Than Expectations


600 billion tons of ice melted in Greenland, the largest ice floe in the North Pole, in 2019. It is reported that this melting directly affects 40 percent of the increase in global sea level. Greenland raised the sea level by 1.5 millimeters in one year.

In recent years, the effects of global warming have started to feel more severe than expected. Greenland ice sheet, which experienced a record reduction, lost 600 billion tons of ice last year. While it is thought that 40 percent of the sea level rise is directly caused by the ice melting in Greenland, it is thought that the predictions made for the next 100 years will pass in a much shorter time considering the current rate of global warming.

Ice melting in Greenland in 1 year raised the sea levels by 1.5 millimeters according to the announced data. Calculating how many tons of ice melts in Greenland every year since 1948, scientists stated that this year’s melting was the biggest loss. In fact, Greenland was melting every year until the end of the 20th century. Therefore, the total amount of ice on the island remained the same. In a scenario where Greenland is completely melted, global sea levels are expected to rise 7 meters.

The problem is not just air temperature
According to scientists’ statement, the problem in Greenland is not just the air temperature. Scientists, who reported that high-pressure zones were formed in the atmosphere in the south of Greenland last year, said that the sky was completely deprived of the clouds, and therefore there were no snow to form fresh ice. Stating that the average recorded in 1890 – 1999 was below 100 billion tons of ice, scientists explained that in the absence of clouds, the sun’s rays melted the existing ice faster.

According to calculations, the melting out of control in Greenland made up 70 percent of the melted water and icebergs flowing to the seas worldwide.

While there were such problems in the southern part of the island, in the northern part, melting from warm and humid air occurred. “Such atmospheric conditions are increasingly being observed in recent years,” said Columbia University professor Marco Tedesco, who led the research, reporting that standard climate models do not take account of conditions like in Greenland.

Estimates do not match
According to a report published by the Intergovernmental Panel on Climate Change in September, it was estimated that sea levels would rise by 1 meter by 2100, but the melting rate in Greenland is almost twice the rate of this estimate, according to a scenario where greenhouse gas emissions will continue to increase.
