Urgent exploration needed for earth-cooling methods
Cambridge scientists say just cutting carbon emissions isn't enough to slow global warming.
One idea—injecting sulfates into the atmosphere to bounce sunlight away—could backfire by causing acid rain and messing up rainfall.
So, they're looking for safer ways to help cool the Earth.
TL;DR
Exploring safer alternatives to cool the Earth
Instead of sulfates, researchers are experimenting with gentler materials lifted by weather balloons (don't worry, nothing's actually released yet).
They're also exploring wild ideas like using seawater to thicken Arctic ice or making clouds over oceans reflect more sunlight.
All these options are being tested carefully to see if they can help without creating new problems.
