By many measures, 2011 was the most extreme weather year for the U.S. since reliable record-keeping began in the 19th century -- and the costs have been enormous: according to the National Oceanic and Atmospheric Administration (NOAA), 2011 set a record for the most billion dollar disasters in a single year. There were 12, breaking the old record of nine set in 2009. The aggregate damage from these 12 events totals at least $52 billion, NOAA found.
Severe weather across much of the nation has raised the question of whether global warming has already begun to influence shorter-term weather patterns, and the specter of even more extreme years to come as global temperatures continue to rise.
According to climate studies, the short answer is yes: the new climate environment created by global warming is making some extreme events, particularly heat waves and heavy rain, more likely to occur and more intense when they do. Climate models have more difficulty predicting how climate change may be influencing other types of extremes, such as severe thunderstorms and tornadoes, but a warming climate provides more fuel to these events in the form of increased water vapor and heat in the atmosphere.
By many measures 2011 was an extreme year for extreme events. Searing heat waves, parching drought, deadly tornadoes, blizzards and floods cost billions of dollars in damage, affected millions of lives and tragically, killed more than a thousand people across the U.S.
Climate Central examined extreme weather events from coast to coast to determine the 10 states that were clobbered the worst. Texas tops that list of hardest hit, with a costly -- and deadly -- combination of intense drought, a punishing heat wave, the worst wildfires in state history, and plenty of tornadoes.
Climate Central’s analysis factored the death toll in each state, damage costs, the disruption caused to daily life, and how unusual the events were compared with what transpires in an average year.
But for these 10 states, little of what transpired was average as extreme weather rewrote the record books in 2011.
Correction: An earlier version of this story contained references to April flooding in Nashville, TN. This flooding occurred in 2010, not 2011. Also, the National Weather Service rated the Apison, TN tornado as an EF-4 on the Enhanced Fujita Scale, not an EF-5 as previously indicated.

Hurricane Irene roared into New Jersey to become one of the state's deadliest and costliest storms, as well as the state's wettest storm in more than a century. Tropical downpours sent rivers and streams overflowing, with nine rivers rising to their highest level ever. The flooding closed 300 roads and highways and interrupted train service for days.
The bill for hurricane damage in New Jersey stands at $1.4 billion already, and at least seven people died during the storm. Then, two weeks later, a second round of drenching rain -- the remains of Tropical Storm Lee -- swept across the state, triggering even more flooding. All told, it was the wettest August and September New Jersey has seen in 117 years.
Just as the Garden State began to dry out, a freak autumn snowstorm hit over the Halloween weekend. The wet, heavy snow stuck to leaves that hadn't fallen from the trees. The result: falling branches that blocked roads and downed power lines, leaving half a million people without electricity -- some of them for days.Â

Climate scientists are telling us if we don't switch to clean energy solutions our weather will get much, much worse. Politicians like to talk about the weather, but who's really doing anything about it?
Food prices have already sparked riots in Algeria and mass protests in Tunisia. We haven't seen the last of resource revolts which, in the coming years, could reach an intensity we scarcely imagine today.
"Texas was hit by eight of the nation's billion dollar disasters -- the most of any state in the country."
=====================================================
You know, with all the evangelicals in the state of Texas, and with the good governor of the state hand-picked by god himself to run for President after his "Go God" pep rally in the state, and with all the righteous people rewriting school books to conform to their religious views of history, and with all the discrimination they allow against others in the name of god, you would think the state would be basking in the glory of paradise.
But no, quite the contrary. Maybe that says something about false prophets and using god's name in vain (if you believe in that sort of thing which it seems much of the state does).
Hmmmmmmmm.

Isn't it logical that a state the size of Texas would be more prone to disaster than a state such as Connecticut. Think about it this way - if Texas was a nation and had all states the size of Connecticut, the nation of Texas could have 48 states.

First of all the Koch Brothers did fund an evaluation of the Global Warming Data and concluded it is true, much to their chagrin. Second, the bible belt sure got hit hard. Maybe god is trying to tell you something
