Scientists say it is inevitable.  Snow melt amounts to hundreds of trillions of tons

Scientists say it is inevitable. Snow melt amounts to hundreds of trillions of tons

  • Exactly 3.3 percent. The Greenland ice sheet, or 110 trillion tons of ice, will melt. This will raise global sea levels by 30 cm
  • Scientists believe it is inevitable, and their predictions are expected to come true by 2100.
  • But they are convinced that even if sea-level rise turns out to be greater than previously thought, rapidly reducing greenhouse gas emissions and keeping warming at 1.5°C would prevent the situation from deteriorating.

The study, published in the journal Nature Climate Change, is far worse than any previous study Complex computer simulations of ice sheet behavior in future global greenhouse gas emissions have produced less worrying predictions. This is due to the fact that the search method has been greatly simplified The Washington Post explains.

Just last year, the Intergovernmental Panel on Climate Change projected an estimated 15 cm rise in sea level by the year 2100. This scenario assumed that humans would emit significant amounts of greenhouse gases over the next 80 years.

In contrast, according to the latest assessment of the Intergovernmental Panel on Climate Change, assuming a rise in greenhouse gas emissions, the “highest possibility” is 1.8 percent melting. Greenland ice sheet and sea level rise of about 13 centimeters by 2100. In the low emissions scenario, this would be just a few centimeters.

The new research produces higher numbers compared to other studies In an interview with The Washington Post, Sophie Nowicki, University of Buffalo Greenland expert. She says one reason for this number is high is that only the last 20 years of warming were included in the study.

The latest study does not take into account any additional greenhouse gas emissions, nor does it specify when this will melt. This is the aspect of studying that gives hope Even if sea-level rise turns out to be greater than previously thought, rapidly reducing greenhouse gas emissions and keeping warming to 1.5°C would prevent the situation from getting worse.

One of the authors of the published research, Jason Box, estimates that 3.3 percent. The Greenland Ice Sheet, or 110 trillion tons of ice, has already been lost and represents the bottom line of what will melt. This will raise global sea levels by 30 cm. The study suggests it could be much worse, especially if the world continues to burn fossil fuels.

A global sea level rise of 30 cm will have dire consequences. If the water level along the coast of the United States rose by an average of 25-30 cm, more destructive floods would occur five times more and moderate floods would become ten times more common. We read in a report from the National Oceanic and Atmospheric Administration.

Low island states and developing countries like Bangladesh are in a worse situation. While they don’t contribute much to warming and melting Greenland’s ice sheet, they don’t have the billions of dollars to adapt to rising water levels.

Greenland is the largest island in the world, and if its ice sheet melted completely, it would raise sea levels by more than 6 metres, and scientists are wondering at the rate of Greenland melting. After all, it is located in the Arctic, which is warming much faster than the rest of the world.
