New study to help water planners in changing climate

There are more and more signs that global warming triggered a step-change in many natural systems in the 1980s. A new study, led by scientists with the National Center for Atmospheric Research, tracked a big change in flows in the Rio Grande watershed, a key source of water in New Mexico and Texas.
According to the study, the percentage of precipitation that becomes streamflow in the Upper Rio Grande watershed has fallen more steeply than at any point in at least 445 years.
In another recent study, European researchers showed how major lakes across Central Europe warmed dramatically starting about that same time, and the meltdown of Arctic ice has also accelerated rapidly since then.
