The Dust Bowl of the 1930s was the worst drought in US history
A primary tenet of global warming alarmism is invalidated.

A recurring theme in my past columns is that a moderate degree of global warming is likely to be beneficial to mankind. Al Gore, on the other hand, says climate change is already causing catastrophic results. In testimony before Congress last March, he stated, "droughts are [already] becoming longer and more intense". But the findings of a group of University of Wisconsin-Madison researchers say otherwise.

The scientists, led by Gemma Narisma, examined 100 years of global rainfall data. Using sophisticated wavelet analysis methods, they identified 30 cases of severe droughts lasting 10 or more years. The results showed the number of droughts dropping sharply over time. From 1900-1920, seven droughts, another seven from from 1920-1940, and eight from 1940-1960. But after that, the picture changes. In the period 1960-1980, only five droughts were recorded, and from 1980-2000 (the warmest period of all), only three occurred. Furthermore, of the most severe droughts, none began in the last 30 years..

The researchers found another surprising result. Changes in rainfall levels are not only much more common than previously thought, but they tend to occur in a very abrupt, unexplained manner. More proof that climate change is part of nature.

The work represents the first systematic survey of abrupt climate changes that have occurred in recent history. Professor Johnathan Foley, who also participated in the research, says the study is important, "because previous work largely focused on ancient climates or theoretical changes in future climates".

The findings are published in Geophysical Research Letters.

No you asherite

the myopia is that he focus's down on one single aspect of what is probably the most complex and important issue of our time.

he finds one inconsistancy in the data or one aspect of the problem. And declares the whole thing as a hoax or conspearacy by the alarmist liberals

well If your right and things aren't so bad, all our efforts will just result in a cleaner enviroment win win for everybody

but if your wrong and I'm right there will be a special place in hell for you and him, who's goal is to intoduce confusion and spin to the situation, so big corperate intrests can continue to pollute to their hearts desire.

although you are right with the creation of the gulf of mexico I should have wrote largest not latest this has happened repeatedly

as far as honest debate there is nothing honest about Mr Ashers articles

where is the [Asher speaks to soon about the hurricane season] he never brings up the inconsistancies with his own pet threories only ones that back his own views

notice how its always global warming not climate change with him

to me he is the guy from the thank you for smoking movie, just insert global warming is a myth instead of smoking

and i have never seen you do anything but back him up are you sure your not him using an extra account

I think quite possibly it's the other way around. The global warming enthusiasts, such as yourself, are like the general public who once believed from listening to the "consensus" from "health experts" (doctors) that smoking is good for you. At the time there were probably "smoking is healthy" skeptics, just like there are AGW skeptics today.
