The millennium year 2000 didn’t wreak
havoc over Earth as expected, but in the 14 years since, western states
including California, Nevada, Arizona, Colorado, New Mexico, Utah and Wyoming
are the driest they’ve been all century.
The extreme drought plaguing western
America has become so severe it is causing the Earth’s crust to rise, leading to
an half inch rise in some places, most dramatically beneath California’s
mountains, where snow packs atop are already melting.
The weight of ground water keeps the
Earth’s crust where it is, but about 63 trillion gallons of water have been lost
since last year, according to GPS measurements
by scientists at the Scripps Institution of Oceanography. Evaporation and
use by people have played a big part, exacerbated by lack of rain. The amount
lost would be enough to cover the entire United
States west of the Rocky
Mountains with a layer of water four inches deep.
There has been an average rise of one-sixth of an
inch across the western region.
