Climate change shrink: sea level rise predictions wrong by 80% | Contact Us | News


Climate change and the effects of global warming will produce between 19 and 63 inches of sea level rise worldwide. Climate scientists at the Geophysical Institute of the University of Alaska Fairbanks fear that these effects will become evident in the next 200 years. And if greenhouse gas emissions remain unopposed and global temperatures continue to rise, Greenland's ice will melt at higher rates than originally expected. Climate forecasts are now up to 80% higher than previous estimates of 35 inches of sea level rise from the Greenland ice melt.

And to further emphasize the criticality of the situation, scientists have warned that all the ice in Greenland threatens to disappear a thousand years from now.

Andy Aschwanden, associate professor of research at the University of Alaska Fairbanks, said: "How will Greenland look in the future – in a few hundred years or 1,000 years – whether there will be Greenland, or at least a Greenland like today? , depend on us."

Terrible climate predictions were presented in a study published in the June issue of Science Advances.

Using data collected by the NASA IceBridge operation mission, scientists projected the Greenland ice to melt until the year 3000.

Based on 500 computational models of three different weather forecasts, the researchers were able to predict the rate of ice melting.

The three different climate scenarios were all dependent on the amount of greenhouse gases in the atmosphere.

If nothing is done to reduce the impact of human-made gas emissions, the Greenland ice sheet will melt by the end of the millennium.

And when that happens, the amount of water released by the icy earth will cause sea level to rise 17 to 23 feet.

This will put much of Los Angeles, San Francisco and New Orleans under water.

US Space Agency NASA said: "In the scenario where emissions are stabilized at the end of the century, instead of continuing to increase, the model shows that the loss of ice has dropped to 26 to 57% of the total mass in 3000.

"Drastically limiting emissions so that they began to decline by the end of the century could limit ice loss from eight to 25 percent.

"This scenario would produce up to six feet of sea level rise in the next millennium, according to the study."

Scientists believe that these up-to-date climate models better represent the flow of water from the glaciers to the oceans.

NASA said that outflow glaciers play a key role in the way ice sheets melt and their melting can contribute to 40 percent of the total ice loss over the next 200 years.

Between 1991 and 2015, Greenland melted ice contributed annually about 0.02 inches to sea level rise.

Mark Fahnestock, who participated in the study, said: "What we know of the last two decades of just observing Greenland is not because we were geniuses and we discovered, but because we just saw this happening."

What are the impacts of climate change?

1. If global temperatures rise by just 1.5ºC, NASA estimates that more than half of the world's population will suffer reduced access to safe water.

2. Heat waves triggered by high temperatures will be more frequent and more deadly, particularly in already hot and dry regions.

3. With a warming of 1.5ºC, NASA said that about 6% of all insects, 8% of plants and 4% of vertebrates will have their "geographic range determined by climate reduced by more than half."

4. Food availability will fall to 2 degrees Celsius of warming in Southern Africa, the Mediterranean, the Sahel, Central Europe and the Amazon.

5. Global warming between grades 1,5C and 2C will cause the world's rainforests to suffer more forest fires and deforestation.
