As we speak, Antarctica and Greenland are both melting down at an accelerated pace. Billions of tons of meltwater from these two regions would reach the world’s oceans. Despite the increasingly higher risks of sea level rise, there is also a high risk for more extreme weather phenomena. According to a recent study, global warming will trigger “climate chaos” by accelerating both Antarctica and Greenland ice sheet meltdown.
“According to our models, this meltwater will cause significant disruptions to ocean currents and change levels of warming around the world,” explained Nicholas Golledge, an associate professor at the Antarctic Research Centre of New Zealand’s Victoria University of Wellington, and the leading author of the new study.
The Antarctic ice sheet meltdown would bring cold water that would trap the warmer water below the surface, which would cause the glaciers to erode from the bottom, accelerating the melting even more.
Global Warming: Ice Sheet Meltdown To Trigger “Climate Chaos”
“The large-scale changes we see in our simulations are conducive to a more chaotic climate with more extreme weather events and more intense and frequent heat waves,” added Natalya Gomez, a researcher in the Department of Earth and Planetary Sciences at McGill University in Canada, and the co-author of the new research.
By the end of the century, according to scientists, the Greenland ice sheet meltdown would considerably disrupt AMOC (the Atlantic Meridional Overturning Circulation) which has already slowed down more than expected before. That would trigger a “climate chaos,” characterized by more extreme weather phenomena.
More specifically, the disruption of the AMOC would trigger warmer temperatures in the high Arctic, eastern Canada, and Central America, while northwestern Europe would experience cooler temperatures. Nonetheless, accelerated Antarctica and Greenland ice sheet meltdown might increase sea levels around the coastlines around the world. Greenland, if it were to melt entirely, would raise the global oceans level by 7 meters, while Antarctica, in case it dissolves completely, would increase sea levels by 58 meters.
