Drying the upper atmosphere: Scientists create new idea to hack warming planet

Government scientists have cooked up a new concept for how to potentially cool an overheating Earth: Fiddle with the upper atmosphere to make it a bit drier.

Water vapor — 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 vapor in the upper atmosphere would get a bit drier and that could counteract a small amount of the human-caused warmth.

Ocean sponges suggest Earth has warmed longer, more than thought

A handful of centuries-old sponges from deep in the Caribbean are causing some scientists to think human-caused climate change began sooner and has heated the world more than they thought.

They calculate that the world has already gone past the internationally approved target of limiting global warming to 1.5 degrees Celsius (2.7 degrees Fahrenheit) since pre-industrial times, hitting 1.7 degrees (3.1 degrees Fahrenheit) as of 2020. They analyzed six of the long-lived sponges — simple animals that filter water — for growth records that document changes in water temperature, acidity and carbon dioxide levels in the air, according to a study in Monday's journal Nature Climate Change.
