Greenhouse Gas Emissions: NASA Reveals More Danger to Earth’s Water Level
By Amila Khan
Greenland and Antarctica are melting ice at a high-speed rate for warming due to greenhouse gas emissions. If this persists, the seas will be in a terrible state in the next 80 years. Just because the ice in Greenland and Antarctica melts, our seas’ water level will rise about one and a half feet.
An international survey led by the US space agency NASA has given this warning.
According to the researchers, the melting of the ice in Greenland and Antarctica at this rate will raise the sea level of all the world’s oceans by more than 15 inches (38 cm) by 2100, which is far more than all the predictions so far. Much more terrifying.
This week’s forecast has been published in a special issue of the international science journal ‘Cryosphere.’ This is based on information from the Ice Sheet Model Inter-Comparison Project (ISMIP6), led by NASA’s Goddard Space Flight Center.
A special report by the Intergovernmental Panel on Climate Change (IPCC) last year warned that by 2100, one-third of our sea-level rise would be due to the melting of Greenland’s thick ice sheets Antarctica.
The IPCC report said that sea levels would rise by 3.1 to 10.6 inches (8 to 27 centimeters) between 2000 and 2100 for Greenland’s melting. And for melting the ice of Antarctica, sea levels will rise by 1.2 to 11 inches (3 to 28 centimeters) this century.
Sophie Nowicky, a professor at the University of Buffalo who is the project’s lead researcher, says, “how much the sea level will rise after 80 or 100 years will depend on the rate at which the very large chunks of ice will melt.
And almost all of those vast chunks of ice are in Greenland and Antarctica. The melting of these ice cubes depends on warming. “
The researchers say Greenland’s ice melting rate has become the cause of most concern. Because the atmosphere’s temperature is much higher than before, the upper layers of Greenland’s massive icebergs are melting faster. And the sea temperature continues to rise, Greenland’s sea-adjacent glaciers have begun to melt.
Researchers have calculated in two ways to make predictions. They found that if the rate of greenhouse gas emissions were higher than it is now, sea levels would rise by three and a half inches (9 cm) in 2100, to melt the pieces of Greenland’s ice.
And if that emission is a little lower, the sea level will rise by 1.3 inches (3 centimeters) in 2100 for Greenland’s ice to melt. Never before has there been such a picture of danger.
Experts believe that this study will play an essential role in preparing the IPCC report in 2022.
