Our overheating planet may cross a
dangerous threshold in the coming years, with one new study warning that the
Arctic may be "transformed beyond
contemporary recognition" if warming continues as expected.
What's happening?
Researchers behind a new study have
outlined the impacts if Earth's temperature rises by 4.9 degrees Fahrenheit by
the end of the century (compared to pre-industrial temperatures). This
threshold is expected to be reached even with countries' pledges to curb
pollution.
"Our paper shows that, already
today, mankind has the power to wipe out entire landscapes from the surface of
our planet," said the
study's co-author, Dirk Notz, a professor for polar research at the University
of Hamburg, per SciTechDaily.
Notz continued, "It'd be
amazing if we could become more aware of this power and the responsibility that
goes with it, as the future of the Arctic truly lies in our hands."
Why is warming in the Arctic
important?
The Arctic is bearing the brunt of
warming around the world, with temperatures in the region rising four times
faster than the rest of Earth. The study suggests that the warming projected to
occur will have dire impacts across the Arctic, endangering wildlife and entire
ecosystems.
"Virtually every day of the year would have air temperatures higher than pre-industrial extremes, the Arctic Ocean would be essentially ice-free for several months in summer, the area of Greenland that reaches melting temperatures for at least a month would roughly quadruple, and the area of permafrost would be roughly half of what it was in pre-industrial times," noted the study, which was published by Science.
The authors continued, "These
geophysical changes go along with widespread ecosystem disruptions and
infrastructure damage, which, as we show here, could be substantially reduced
by increased efforts to limit global warming ."
The U.S. National Oceanic and
Atmospheric Administration recently reported another
key threshold has been reached in the Arctic. The agency's 2024 Arctic
Report Card cautioned that the region releases more carbon dioxide into the
atmosphere than it stores.
What's being done about the
rapid rise in temperatures in the Arctic?
Scientists are using a
powerful new
AI tool to help forecast future changes in Arctic sea ice up to at
least a year in advance. The projections from this groundbreaking model will
help policy-makers make critical decisions about how to best protect this
important region.
Preventing the century-end warming
projected in the study will require a concerted effort to cool our planet,
including a concerted move away from dirty
energy sources and toward cleaner, cheaper
options.
But as individuals, there are
plenty of things we can all do to keep our planet cooler. Installing
solar panels , opting for induction
stoves instead of conventional ranges, and choosing
an EV for the next vehicle purchase are all examples of things we can
do. Many of these upgrades, like installing solar panels , can also help you reduce your
energy bills.
