Climate Change, Extremes Have Human Causation, Science Says

Definitive science.

(CBS News) On Tuesday, for the first time, government scientists are saying recent extreme weather events are likely connected to man-made climate change. 
It's the conclusion of a report by the National Oceanic and Atmospheric Administration.

The report says last year's record drought in Texas was made "roughly 20 times more likely" because of man made climate change, specifically meaning warming that comes from greenhouse gasses like carbon dioxide. The study, requested by NOAA, looked at 50 years of weather data in Texas and concluded that man-made warming had to be a factor in the drought.

The head of NOAA's climate office, Tom Karl, said: "What we're seeing, not only in Texas but in other phenomena in other parts of the world, where we can't explain these events by natural variability alone. They're just too rare, too uncommon."

Aside from the Texas drought, NOAA called the entire year of 2011 the year of extreme weather events, starting in Joplin, Missouri...

All told, there were seven tornado outbreaks in America last year that caused a billion dollars or more in damages. There were increased hurricanes in the North Atlantic, unprecedented flooding in Australia but widespread drought in East Africa, and all of that was caused by La Nina. Typically La Nina is marked by a sharp cooling in the Pacific, but last year's La Nina was the warmest ever, and again the government concluded that global climate change played a role.

"What's happening is, these normal fluctuations between El Nino and La Nina events that lead to some of the extreme conditions, become more extreme, more intense than they otherwise might have been because we've got increased greenhouse gases in the atmosphere leading to a warmer planet," Karl said.

NOAA made a point of saying in their study that the climate change they've identified is man-made.

Going back 50 years, they know what temperature and dryness conditions are associated with Texas drought. When they put that in the computer, nothing explained the intensity and duration of what we saw last year in Texas until they factored in the added heat coming from climate change. You're going to see a lot of scientists criticizing this as a guess, but NOAA for the first time is arguing that this is science.

Climate is caused by CO2!!!! CO2!!! CO2!!! The most dangerous chemical pollutant in the world!!!
Those lying corporate interests who try to lie and say it is the sun are LYING!!!! LYING!!!!
LYING!!!!
There is NO POSSIBLE WAY that two droughts in a row can be caused by anything other than HUMANS!!!
HUMANS USING LIGHTBULBS!!!!! AND DRIVING SUVS!!!!!
Those lying liers talk about the droughts of the 30’s and THEY ARE LYING!!!!! IT NEVER HAPPENED UNTIL NOW!!!! BECAUSE OF CO2!!!!
LISTEN TO SCIENCE!!!!
AND ALGORE!!!
And THE SCIENCE OF ALGORE!!!!!

Take this screaming meemie off to the mental institution . . .

ALgore is right!! And he is NOT crazy!!! said...

Right as rain and as serious as a drought!!! Rain and drought both predicted by COMPUTER MODELS !!
SCIENTIFIC COMPUTER MODELS!!!!
These computer models predicted both rain and droughts would be caused by human CO2 EMISSIONS!!!
And now it can be seen that they are CORRECT!!!
Do not believe the lying liars who claim the predictions are not true!! These are the same people that will tell you that Jean Dixon did not predict the assassination of John F.Kennedy!! Yes, she did predict it! And the SCIENTIFIC computer models predicted rain and drought caused by human CO2!!!
We must now all believe AlGore!!! And believe the SCIENCE!!! The science of PREDICTING rain and drought by computer models!!!! Rain and drought caused by CO2!!!!
We must STOP BURNING COAL IMMEDIATELY!!!!
We must STOP USING ENERGY IMMEDIATELY!!!!!!!!!!
LISTEN TO ALGORE!!!!!!
LISTEN TO SCIENCE!!!!!!!
DON’T LISTEN TO REPUBLICANS!!!!!!!!!!
THEY ARE LYING!!!!!!
LYING, LIARS, LYING!!!!!
SCIENCE DENIERS!!!!! denying….SCIENCE!!!!!!!
Be smart, be scientific, listen to ALGore and
SAVE THE DAMN PLANET ALREADY!!!!!
