The climate change simulations that best capture current planetary conditions are also the ones that predict the most dire levels of human-driven warming, according to a statistical study released in the journal Nature on
Oxygen levels, dissolved minerals among factors responsible for high concentrations of radium in untreated water from aquifer that underlies six states
U.S. Geological Survey scientists have shed new light on processes that happen deep underground. These processes — which cause radium to leach from aquifer rocks into groundwater — are responsible for high concentrations of naturally occurring radium in groundwater from the Cambrian-Ordovician aquifer.
