Expect More Droughts, Heavy Downpours, Excessive Heat, And Intense Hurricanes Due To Global Warming, NOAA

ScienceDaily (June 20, 2008) — The U.S. Climate Change Science Program and the Subcommittee on Global Change Research has released a scientific assessment that provides the first comprehensive analysis of observed and projected changes in weather and climate extremes in North America and U.S. territories. Among the major findings reported in this assessment are that droughts, heavy downpours, excessive heat, and intense hurricanes are likely to become more commonplace as humans continue to increase the atmospheric concentrations of heat-trapping greenhouse gases.
The Intergovernmental Panel on Climate Change previously evaluated extreme weather and climate events on a global basis in this same context. However, there has not been a specific assessment across North America prior to this report.
The report is based on scientific evidence that a warming world will be accompanied by changes in the intensity, duration, frequency, and geographic extent of weather and climate extremes.
"This report addresses one of the most frequently asked questions about global warming: what will happen to weather and climate extremes? This synthesis and assessment product examines this question across North America and concludes that we are now witnessing and will increasingly experience more extreme weather and climate events," said report co-chair Tom Karl, Ph.D., director of NOAA’s National Climatic Data Center in Asheville, N.C.
"We will continue to see some of the biggest impacts of global warming coming from changes in weather and climate extremes,” said report co-chair Gerry Meehl, Ph.D., of the National Center for Atmospheric Research in Boulder, Colo. "This report focuses for the first time on changes of extremes specifically over North America."
Global warming of the past 50 years is due primarily to human-induced increases in heat-trapping gases, according to the report. Many types of extreme weather and climate event changes have been observed during this time period and continued changes are projected for this century. Specific future projections include:
Abnormally hot days and nights, along with heat waves, are very likely to become more common. Cold nights are very likely to become less common. Sea ice extent is expected to continue to decrease and may even disappear in the Arctic Ocean in summer in coming decades. Precipitation, on average, is likely to be less frequent but more intense. Droughts are likely to become more frequent and severe in some regions. Hurricanes will likely have increased precipitation and wind. The strongest cold-season storms in the Atlantic and Pacific are likely to produce stronger winds and higher extreme wave heights.
The National Oceanic and Atmospheric Administration, an agency of the U.S. Commerce Department, is dedicated to enhancing economic security and national safety through the prediction and research of weather and climate-related events and information service delivery for transportation, and by providing environmental stewardship of our nation's coastal and marine resources.
NOAA plays a key role in the Climate Change Science Program, which is responsible for coordinating and integrating climate research, observations, decision support, and communications of 13 federal departments and agencies.
The National Center for Atmospheric Research investigates climate, weather, and other topics related to the atmosphere. It is sponsored by the National Science Foundation and managed by a nonprofit consortium of universities, the University Corporation for Atmospheric Research.

To think this stuff can be spouted off with little or no accountability.
Can you clarify that statement? Nobody has predicted 31 hurricanes during the last 2 years (combined...or even the last 3) and we have had hurricanes...including two cat 5's last year (Dean, Felix).
it’s 69 degree F in Manhattan at this moment. And it’s the middle of June.
Sounds like something an end times preacher would come up with, Does the report say anything about earthquakes.
Oh for Gods Sake!! SPARE ME!! Gosh I am so sick of this BS.
Next they will be telling us that Dogs and Cats will be living together, mass hysteria!!!!
UGH!
I’m with you.
LOL LOL :-)
Plagues, darkness, the dead rising from the grave,forty years of darkness, earthquakes, volcanoes,riots in the streets, dogs and cats living together, mass hysteria!

I thought the “intense Hurricanes” claim for global warming had already been disproven.
They don't know shit.
ok excessive rain and drought at the same time?
I am just not getting this whole GW thing.
IOW, expect weather.
me thinks it’s Mother Nature’s way of saying to Algore...”hey, listen you POS, you don’t know what the &%$@ you’re talking about...want proof? watch this!”
Interesting that this would come out after the DRILL NOW campaign has really gotten HUGE momentum. I don’t believe a word of it. We have had weird weather for a few years now so I wouldn’t be surprised if we had a bad hurricane and more tornadoes but that does NOT mean it’s a result of global warming.
The temperature was low enough to cause our furnace to come on this morning, June 19th. That means it had to drop below 64 degrees in the house.
There was snow here in Upstate New York on the last day of April.
