New study of hydropower developmt vs flood risk at 107 hydropower dams finds 41% of the dams provide flood mitigation & 26% dams likely increase flood risks. Dams with shorter downstream river lengths tend to more flood-inducing than flood-protecting. agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Yay for steps in the right direction! One thing that keeps me going in hard times is the knowledge that solutions abound. We can have a healthy, fair & sustainable economy. Don’t let anyone convince you otherwise. We face strong headwinds who profit from the status quo, but together we are stronger!

Germany’s famous study showed over 80% insect declines in farmland over 27 years. “Those findings were often blamed on pesticides and habitat loss. Sockman’s work shows something different. Insects are collapsing even in a meadow with little human pressure. Climate itself may be enough.”

Over 20 yrs of flying insect counts at a remote high(3000m)-mountain meadow in Colorado (by a very dedicated observer) shows insect counts fell by an average of 6.6%/yr, overall a 72.4% drop. The main culprit was rising summer temperatures, especially warmer nights. ½ www.earth.com/news/remote-...
