Scientists find new hack to deal with a warming planet; Here’s how
Water vapour — water in its gas form — is a natural greenhouse gas that traps heat, just like carbon dioxide from burning coal, oil and gas. So, researchers at the National Oceanic and Atmospheric Administration and NASA figure if they can just inject ice high up in the air, water vapour in the upper atmosphere would get a bit drier and that could counteract a small amount of the human-caused warmth.
It's just the spark of an initial idea, said the lead author of a study in…
