Study finds Colorado River Basin’s worst known megadrought was 1,800 years ago

Green Car Congress

The new study used tree-ring data and other climate records to identify a drought period unmatched in severity by the current drought or other ancient droughts. The new knowledge for how much worse droughts can be, even without anthropogenic climate forcing, points to a potentially grim outlook for water in the West.

Study finds global rivers and streams emitting 3x IPCC estimates of the GHG N2O

Green Car Congress

That’s three times the amount estimated by the Intergovernmental Panel on Climate Change (IPCC). Nitrous oxide is a potent greenhouse gas that contributes to climate change and stratospheric ozone destruction. —Jake Beaulieu of the University of Notre Dame and the US EPA, and lead author of the PNAS paper.
