A perfect storm of fire and ice may have led to snowball Earth
Boston MA (SPX) Mar 15, 2017
What caused the largest glaciation event in Earth's history, known as 'snowball Earth'? Geologists and climate scientists have been searching for the answer for years but the root cause of the phenomenon remains elusive. Now, Harvard University researchers have a new hypothesis about what caused the runaway glaciation that covered the Earth pole-to-pole in ice. The research is published in Geophysical Research Letters. Researchers have pinpointed the start of what's known as the Sturtian snowball ... read more
