“Many scientists are now raising the possibility
that abrupt, catastrophic switches in natural
systems may punctuate the steady rise in global
temperatures now underway.”
“In the interior United States, a widespread
drought that began in the Southwest about 6 years
ago could be the leading edge of a new climate
regime for a wider region.”
“[There is an] urgent need for committed and
sustained monitoring of those components [that]
are particularly vulnerable.”

Abrupt Climate Shifts May Come Sooner, Not Later
Rising Seas, Severe Drought, Could Come in Decades, Says U.S. Report

San Francisco– The United States could suffer
the effects of abrupt climate changes within
decades-sooner than some previously thought–says
a new government report. It contends that seas
could rise rapidly if melting of polar ice
continues to outrun recent projections, and that
an ongoing drought in the U.S. west could be the
start of permanent drying for the region.
Commissioned by the U.S. Climate Change Science
Program, the report was authored by experts from
the U.S. Geological Survey, Columbia University’s
Lamont-Doherty Earth Observatory and other
leading institutions. It was released at this
week’s meeting of the American Geophysical Union.
