"Current predictions of ice melt in the Arctic are probably way off. According
to an updated model, glaciers in the icy north could be slipping into the sea
up to 100 times faster than previously forecasted.
This isn't the first time ice melt predictions have been scrutinized or
revised. In 2020, a study found that the current computer simulations of how
glaciers interact with the rest of the climate system don't quite match up with
reality.
Something in our current models must be incorrect, or the models must be
missing something. But what?
Scientists at the University of Texas at Austin (UT) think they've figured out
at least part of the problem.
Gaps in data meant that climate scientists have been plugging in observations
from accessible glaciers to build models of how all glaciers melt.
But what's happening to the Antarctic ice sheet amid rapid global warming is
significantly different from what's occurring to Arctic glaciers.
In Greenland, for example, recent observational research has found that warm
ocean water in the nation's fjords is chiseling away at parts of the floating
ice sheet from underneath."
