Dust storms suck, but could help slow global warming, which is a very very good thing since it’s likely temps will increase more than 7 °F in the next 40 or 50 years.  This is an incredible rate of warming – more than 250 times faster than one of the fastest warming periods (that we know of) in Earth’s history, the Paleocene-Eocene Thermal Maximum.  Up to 50% of marine species went extinct in that event.  How many will we lose this time?
