Researchers Have a Theory on How to Stall Global Warming and It Involves Dimming the Sky

What's that now?

Though climate change is an urgent threat, the efforts to counteract it still remain politically divisive. Time is running out.

That’s why a group of researchers is playing the long game, determining solutions for an Earth ravaged even more by erratic weather and lessened sustainability.

To counter extended heatwaves—inevitable if the issue of climate change and rising temperatures go unmitigated—researchers wrote in a paper for Nature Climate Change that dimming the sun’s rays by spraying sulfate aerosols into Earth’s atmosphere would lessen the impending damage.

The phenomenon happens naturally in certain regions when volcanic ash projects into the sky, effectively dimming solar rays.

While the risks of this method are uncertain, the researchers insist that no land mass would be effected more negatively than the effect climate change would have.

However, the plan is being met with criticism from other experts.

Alan Robock, an environmental science professor at Rutgers, told The Atlantic:

“I don’t think it is correct to imply that geo-engineering is a good or safe idea…and there is no way to do what they modeled, as we cannot turn down the sun.”

Robock is referring to the simulations run by the research team, whose simulation ran on reduced solar rays rather than application of sulfate aerosols.

Robock isn’t the only skeptic.

Rather than planning for imminent doom, maybe we should consider something else.

Like taking steps now to offset the crisis rather than waiting until we’re at the brink of its worst effects.

Regardless of what happens, it looks like dark skies ahead.
