Conditions that, by today’s standards, are considered to be mega-droughts — or conversely, abnormally wet “mega-pluvial” events — may become the average in the future, according to new research led by the University of California Santa Barbara (UCSB) and co-authored by scientists at the National Center for Atmospheric Research (NCAR).
The western US is facing a greatly heightened risk of extreme rain-after-fire events, which can cause mudslides, flash floods, and significant destruction.
A new study challenges a commonly accepted explanation that a "sudden stratospheric warming" caused the unusually cold weather over the U.S. early last year, a view which was widely reported in the media and discussed among scientists at the time.
