Fluctuations in the weather can have a significant impact on melting Antarctic ice, and models that do not include this factor can underestimate the global impact of sea level rise, according to Penn State scientists.


“We know ice sheets are melting as global temperatures increase, but uncertainties remain about how much and how fast that will happen,” said Chris Forest, professor of climate dynamics at Penn State. “Our findings shed new light on one area of uncertainty, suggesting climate variability has a significant impact on melting ice sheets and sea level rise.”

While it is understood that continued warming may cause rapid ice loss, models that predict how Antarctica will respond to climate change have not included the potential impacts of internal climate variability, like yearly and decadal fluctuations in the climate, the team of scientists said.

Rising Temperature Could Melt Antarctica ‘Irreversibly’, Warns New Study

KEY POINTS

  • Researchers say melting Antarctic ice could raise sea level by 8 feet
  • Such a rise in sea levels would devastate coastal cities and cultural sites around the world
  • Study says the only solution is to bring the world’s temperature back to pre-industrial levels

Coastal cities and cultural sites around the world could soon be submerged in water if the melting of ice in Antarctica reaches an “irreversible” level. If global warming is allowed to continue unchecked, most of Antarctica will be gone forever, a new study warns.  

The melting of ice in Antarctica can make glaciers the size of Florida slide into the ocean, said Anders Levermann, a researcher at the Potsdam Institute for Climate Impact Research in Germany, and a co-author of the study. The team ran computer simulations to identify “where exactly and at which warming levels the ice in Antarctica would melt.”  

“We find that

Antarctic Ice Sheet to melt, raise sea levels by 8.5 feet even under Paris Agreement

Sept. 23 (UPI) — The Antarctic Ice Sheet will suffer irreversible ice loss raising ocean levels by 8.5 feet even if the world meets global warming goals laid out by the Paris Agreement on Climate change, scientists said in a report published Wednesday.

The analysis determined there are a number of temperature thresholds above pre-industrial levels that will ultimately lead to increasing sea levels if the world’s nations don’t rein in emissions and global warming.

The study, published Wednesday in the journal nature, was conducted by researchers at the Potsdam Institute for Climate Impact Research and the University of Potsdam in Germany, Columbia University in New York City, and Stockholm University in Sweden.

The researchers determined that if global warming is maintained at 2 degrees Celsius above pre-industrial levels — as laid out by the Paris Agreement — sea levels would rise by 8.5 feet.

If the climate agreement is
