Study Finds Ozone, Nitrogen Change the Way Rising CO2 Affects Earths Water

Green Car Congress

The researchers concluded that models of climate change may be underestimating how much water is likely to run off the land and back into the sea as atmospheric chemistry changes. Either way, water resource managers need more accurate runoff estimates to plan better for the changes. Credit: NASA. Click to enlarge.

The Why, How, and Maybe Not of Geoengineering

Cars That Think

Eliza Strickland: Man-made climate change is already reshaping our planet, and carbon emissions aren’t coming down fast enough to stave off real disaster in the decades to come. It’s often called geoengineering in the popular press, but the preferred term is climate intervention. Transcript. They also mix with clouds.
