Reflecting the urgency and scale
scientists have called for to cope with
climate change, the U.S. and Chinese presidents laid out ambitious new targets Wednesday to cut pollution in a deal that negotiators hope will inspire
similarly dramatic commitments from
other countries.
Scientists have long taken a
similarly cautious stance, but more are starting to drop the caveat and link
climate change directly to intense storms and
other extreme weather events, such as the warm 2012 winter in the eastern U.S. and the frigid one in Europe at the same time.
