For GSS Climate Change chapter 8. Excerpt: New analyses find evidence
of human-caused climate change in half of the 12 extreme weather and
climate events analyzed from 2012. ...according to the report
...released today by the Bulletin of the American Meteorological
Society. Key findings include: Human-induced climate change had little
impact on the lack of precipitation in the central United States in
2012. ...however, human-induced climate change was found to be a factor
in the magnitude of warmth and was found to have affected the likelihood
of such heat waves. High temperatures, such as those experienced in the
U.S. in 2012 are now likely to occur four times as frequently due to
human-induced climate change. ...The record-setting impacts of Sandy
were largely attributable to the massive storm surge and resulting
inundation from the onshore-directed storm path coincident with high
tide. ...climate-change related increases in sea level have nearly
doubled today’s annual probability of a Sandy-level flood recurrence as
compared to 1950. ...The extremely low Arctic sea ice extent in summer
2012 ... cannot be explained by natural variability alone. Summer Arctic
sea ice ... is expected to be largely absent by mid-century. ...The
unusually high amount of summer rainfall in the United Kingdom in 2012
was largely the result of natural variability. ...The July 2012 extreme
rainfall events in North China and southwestern Japan were mainly due to
natural variability.... http://www.noaanews.noaa.gov/stories2013/20130905-extremeweatherandclimateevents.html. NOAA. |
