'Geoengineering is often presented as a last-resort technological fix to the
climate crisis that can still swoop in and save the day.
But new models suggest that such risky measures, like dimming the Sun, are not
enough to save Antarctica now.
There's only one thing left that could, and it's the very same thing we've been
failing to do for 40 years now: stop burning fossil fuels.
In the face of disastrous fires, floods, and other extreme weather events that
have plagued the Northern Hemisphere's summer, there's been renewed interest in
the potential of geoengineering. The incentive to try potentially dangerous
solutions will only grow stronger as climate-driven disasters intensify.
"The window of opportunity to limit the global temperature increase to below 2
degrees is closing fast, so it is possible that technical measures to influence
the climate will be seriously considered in the future," says University of
Bern glaciologist Johannes Sutter.
So Sutter and colleagues decided to investigate what impact dimming the Sun
would have on one of the fast approaching climate tipping points that
researchers are most concerned about.
"Observations of ice flows in West Antarctica indicate that we are very close
to a so-called tipping point or have already passed it," explains Sutter, "with
our study, we therefore wanted to find out whether a collapse of the ice sheet
could theoretically be prevented with solar radiation management."'
