Perspective: Saving the ArcticArctic Ice Is Melting Faster Than Expected. These Scientists Have a Radical Idea to Save It.

Published 30 September 2019

glaciers, polar land, and sea ice are rapidly melting, much faster than many scientists expected, as the Intergovernmental Panel on Climate Change’s (IPCC) report on oceans and the cryosphere released Wednesday reiterated. During a five-day heat wave this summer, Greenland lost more than 60 billion tons of ice, including the biggest loss in a 24-hour period since record-keeping began. Recent projections warn that Arctic summers could be nearly ice-free in 10 to 40 years. These grim warnings have prompted more researchers to apply technological solutions that intervene in the earth’s climate systems to slow the impacts of global warming, also known as “geoengineering.”

Tiny glass beads might seem an unlikely hero in the fight against climate change, but they may end up playing an outsize role in tackling one of the natural world’s most dire predicaments. A group of researchers have found that millions of these spheres spread in a layer across swaths of Arctic ice reflects sunlight and helps keep the ice frozen.

Maris Endicott writes in Mother Jones that glaciers, polar land, and sea ice are rapidly melting, much faster than many scientists expected, as the Intergovernmental Panel on Climate Change’s (IPCC) report on oceans and the cryosphere released Wednesday reiterated. During a five-day heat wave this summer, Greenland lost more than 60 billion tons of ice, including the biggest loss in a 24-hour period since record-keeping began. Recent projections warn that Arctic summers could be nearly ice-free in 10 to 40 years. Arctic ice levels are both a primary indicator of rising global temperatures and a key determinant of how bad climate change might get. Serious ice loss means sea levels rise, more heat is absorbed by the ocean and planet, and weather and ocean currents could change.

Endicott writes:

These grim warnings have prompted more researchers to apply technological solutions that intervene in the earth’s climate systems to slow the impacts of global warming, also known as “geoengineering.” Last week, leading up to the United Nations Climate Action Summit on Monday, a contingent of climate organizations partnered with the U.N. to host the First Annual Global Climate Restoration Forum to discuss geoengineering solutions. While climate engineering was previously considered too far-fetched, risky, or controversial, more people are now seeing the strategy as a necessary piece of the puzzle.
