Study finds heat waves speed snowmelt substantially, but rivers respond unevenly

A new study by researchers at Montana State University has found that heat waves substantially accelerate the melting rate of mountain snowpack; however, the resulting water doesn't necessarily produce an immediate increase ...

The way Earth's 'thermostat' works may have changed during Pangea era

Life arose on Earth at least 3.5 billion years ago, and our planet has remained habitable ever since—not too hot, not too cold. These life-sustaining conditions are possible in part thanks to a built-in, carbon cycle–based ...
