clouds on the horizon

A NASA study in December 2008 found that warming [of more than a degree and a half Fahrenheit] was enough to trigger a 45 percent increase in thunder-clouds that can rise five miles above the sea, generating ‘super-cells’ with torrents of rain and hail.

In fact, total global rainfall is now increasing 1.5 percent a decade. Larger storms over land now create more lightning; every degree Celsius brings about 6 percent more lightning, according to the climate scientist Amanda Staudt.

In just one day in June 2008, lightning sparked 1,700 different fires across California, burning a million acres and setting a new state record. These blazes burned on the new earth, not the old one.
