Global warming will show its effects more clearly as ice shelves in Greenland and Antarctica are melting at an alarming rate, scientists found in a new study. If current greenhouse gas use continues, the ice sheets will melt and add more than 38 centimeters to global sea level rise by 21
It should be noted that this increase has been calculated based on current greenhouse gas consumption and the resulting amount is greater than the amount already set in motion by the Earth’s warming climate. This new study was part of the Ice Sheet Model Intercomparison Project (ISMIP6).
An international team of more than 60 ice, ocean and atmospheric scientists had come together to carry out the relevant research Data obtained from NASA’s Goddard Space Flight Center to use in Greenbelt, Maryland. Ice researcher Sophie Nowicki, who was the project leader, said: “One of the biggest uncertainties when it comes to how much sea levels will rise in the future is how much the ice sheets will contribute” and “how much the ice sheets will contribute” really depending on what the climate will do. “
The ISMIP6 team examined two future scenarios regarding the predicted rise in sea level. In the period from 2015 to 2100, one number was calculated taking into account high carbon emissions and the other taking into account lower emissions. In the case of high emissions, the researchers found that the Greenland ice sheet would lead to an additional global sea level rise of around 9 cm by 2100. In the lower-emission scenario, on the other hand, the loss of the same ice cover would increase the global sea level by around 3 cm.
Calculating the Antarctic layer was more difficult as the East Antarctic ice sheet can increase in mass due to global warming as warmer temperatures lead to increased snowfall. The study was published in a special issue of the journal The cryosphere.
Earlier, a report The Institute for Economy and Peace had suggested that climate change and population growth could displace more than 1.2 billion people by 2050.
