WASHINGTON -- The deadliest tornadoes in decades. Severe flooding on the Mississippi River. Drought in Texas, and heavy rains in Tennessee.

What's up with the weather?

Scientists say there are connections between many of the severe weather events of the past month and global warming.

"Basically, as we warm the world up, the atmosphere can hold more moisture in it," said Anne Jefferson, an assistant professor in the geography and Earth science department at the University of North Carolina, Charlotte.

"Glaciation and Global Warming" 1992 was a group multidisciplinary effort I read, where one of the main early effects of AGW would be climate fluctuation beyond historic. I believe we are in that foggy area of first going beyond historic. Here is what is happening nearby,
From the Aspen Times;


ASPEN — Environmental warrior Bill McKibben doesn't think it's a coincidence that the world has become an increasingly disaster-prone place.

Many of the natural disasters that plague the globe aren't so natural in his view. With the exception of earthquakes and volcanic eruptions, he said, human fingerprints are all over the cataclysmic events.

There is a common bond between killer tornadoes, devastating drought and overwhelming floods hammering the U.S. this spring with recent epic flooding in Pakistan and Australia, rains that have wiped out cropland and infrastructure in Colombia, last year's heatwave that ruined Russia's grain harvest and current droughts threatening crop failure in Europe. That bond is global warming caused by the burning of fossil fuels, he said.

McKibben doesn't contend that any individual event can be directly tied to global warming or that one of the deadly tornadoes in the U.S. was more intense because of global warming. His point is that global warming is creating conditions ripe to produce more cataclysmic events.

“The world we're building is a more violent and dynamic place,” said McKibben, founder of the environmental organization 350.org and a Schumann Distinguished Scholar at Middlebury College. The warmer atmosphere sucks more moisture from the earth, creating large areas of drought, and dumps extraordinary amounts of rain and snow on other areas, creating floods. The warmer climate is also a wetter climate, about 4 percent wetter than just 30 years ago, he said.

Global warming also places more energy in the system. “It loads the dice for all sorts of events,” McKibben said.

McKibben will be a member of a panel Monday at the opening session of the Aspen Environment Forum. The annual conference presented by the Aspen Institute and National Geographic will explore the consequences, challenges and opportunities of the swelling world population. The conference will continue through June 2, with most events at the Aspen Meadows Campus.

In the opening event Monday evening, the panel will discuss “Coping with Calamity: The Art of Looking Ahead.” The premise, according to a description of the event, is that humankind is more vulnerable than ever to disasters because the swelling population has forced sprawl and development in places where it's not so wise (think of nuclear reactors on tsunami-prone parts of the Japanese coast). Events like tornadoes and floods have a greater likelihood of hitting populated areas because of the development patterns of the last five decades, the theory goes.

McKibben said from his Vermont home Thursday that development is a contributing factor to the world becoming more disaster-prone, but not the root cause. He will offer a different twist to the panel discussion. There is potential for more disasters of greater magnitude because global warming is projected to increase another 4 degrees Celsius before this century is finished, he said. That is about four times the amount it warmed over the last century. Climate modeling suggests that level of warming will be accompanied by an increased number of cataclysmic events.

McKibben said humankind needs to respond in a couple of ways. First, it needs to build more resilient systems that aren't as prone to disaster. An example, he said, is the local food movement — supporting food production in or near your community.

Second, and more importantly, is reducing global warming. “We have to prevent it from warming so much that we can't deal with it,” McKibben said.

Here is more on the reasons for increased storms, floods and droughts from increasing AGW:
http://www.sciencenews.org/view/generic ... lf-century

half a degree C up until 2000 lead to 4% increase in atmospheric H2O, then .24*C since 2000, so now close to 6% increase.
Going up geometrically means we will see worse storms in 10 years and much worse in 20 years, unless emissions are brought way down.
Where are those denialists that were here?? Can't deny data now can they. Pukes. :razz: =P~ #-o :mrgreen:

Yes, this year is setting records beyond historic in both temperatures and weather effects like tornadoes and drought.
It is still nothing compared to what is coming, even if people do the smart thing and reduce fossil fuel use 90% within 5 years---good luck!!! Too little, too late won't cut it!
Go to a steady state economy as described in Herman Daly's books, or go business as usual and get ours and many other species extinct.
Sha La La La La La Live for today, let's not worry about tomorrow, hey, hey, hey. I remember that hedonistic garbage song about pure selfishness.
I do believe all those who didn't help like I did and do, will go to hell or the equivalent. :twisted: :razz: :mrgreen:

Global warming has become the most complicated issue, due to Climate change is a problem that is affecting people and the environment.

I disagree... it is becoming increasingly simple... do something. What to do you ask? Quit buying stuff (including utilities) by making your own stuff, learning to live comfortably without stuff, and only buy stuff you will never buy twice. An example is to buy a water filter unit instead of buying bottled beverages... one purchase that eliminates a lifetime of purchases. Every item you buy has to be transported, packaged, marketed and made... lots of energy use all along the way. Furnaces are a new thing to society... so is insulation. Quit buying furnaces and air conditioners and start adding insulation and air-tightness to your buildings. The solutions are simple but not easy. The solutions are often expensive but save you money after a short payback time. Two parts of the USA have roughly 5 times the cost of energy in one part as compared to the other and very little has changed so saving money is not a motivator for people. For me, I am interested in financial independence as I am assuming it is too late for the environment but my actions are the same "green" things... but a different motivator. Other then pet food, I have not bought stuff I will not keep for a long time in about 4 months... but I am buying a meal plan at the university. The reason it is so cheap is it takes far less energy to move food in bulk, wash dishes on an industrial scale, and cook very large batches of food. I may continue this until I can make all my own food in a greenhouse and eat it raw and fresh (no cooking and no refrigeration... two big energy suckers). Total energy use is roughly categorized into 1/5 sections (close to 20%) as follows, home heating/cooling/lights -1/5, industrial heating/cooling/lights - 1/5, transportation (half of that is jet planes) -1/5, manufacturing -1/5, agriculture -1/5. You alone are responsible for the 1/5 that is your house. Of the rest, it is figured that roughly 70% of all energy use is connected to getting food on your table (some of that will be in your home's heating and cooling 1/5) so you can eliminate much of that energy use just by growing your own food. Never buy a jet plane ticket and you have another 10% covered. As you can see, a bit of work on your house design and you have reduced your footprint by .10+(.70 x .70)+.20= 80% with the only lifestyle changes being make your own food and energy and never fly. The remaining 20% is all the stuff you buy... never buy stuff you are going to throw away (including the packaging if you can). Yep, it is simple but not easy.

And simply isn't going to happen. Might as well enjoy the ride and embrace destiny. I welcome a simpler time when all there is to worry about is the next meal, keeping comfortable, both being totally my responsibility.

Global warming is leading to such severe storms, droughts that nations should prepare for an unprecedented onslaught of deadly and costly weather disasters, an international panel of scientists has said.Hurricanes bring winds and slashing rains that flood streets. Researchers also found that this increase would occur during typical stormy seasons and not during dry seasons when it may be beneficial and Sea level rise also makes storm surges more destructive.There are lots of places that are already marginal for one reason or another.
