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.

I think what is "too far" will differ for everyone (opinion). If you're in a village that gets flooded you might have a different perspective.

I think the reality is that "nature" is not really worried about individuals and it doesn't have a measure of what "too far" is. Nature is not reasoning, it is simply adjusting and going through cycles. I highly suspect that plenty species died before any significant human civilization or technology was ever around. To try to "fix" (or worse yet, stop) a process that we don't understand I think it man's ultimate arrogance. Long before we recorded our imperfect recordings nature was still doing it's thing and getting along just fine. Death happens, extinction happens and it's really just part of the way things are.

Don't for one second believe that I think humans should not conserve or take care of the environment. Letting things flow as they will is not the same as purposeful waste and foolishness.
