I believe the weather we have been having is unusual. I would like to know if it is a result of Global warming. Thanks for comments. Joe L. Ogan
However, there are many articles indicating that more of the weak tornadoes are being detected now than had happened in the past. I.E. We now are close to the technology to detect every single dust devil.
But while the numbers are not contested, their significance most certainly is. Another study considered how this information was being collected, and research suggested that the increase in reported storms was due to improved monitoring rather than more storms actually taking place.
==Quote=Globally (not just in the North Atlantic), there is an average of about 90 tropical storms every year. According to the 2007 Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC-AR4), globally "[t]here is no clear trend in the annual numbers [i.e. frequency] of tropical cyclones."However, in the North Atlantic there has been a clear increase in the frequency of tropical storms and major hurricanes. From 1850-1990, the long-term average number of tropical storms was about 10, including about 5 hurricanes. For the period of 1998-2007, the average is about 15 tropical storms per year, including about 8 hurricanes. This increase in frequency correlates strongly with the rise in North Atlantic sea surface temperature, and recent peer-reviewed scientific studies link this temperature increase to global warming. ===Image from here.
It's your local weather changing, for better or worse, probably worse.
As most of the weather phenomena in our world everything seems linked to everything else. To attach a secure vote of confidence to a open non-linear system? Can you do that?
But while the numbers are not contested, their significance most certainly is. Another study considered how this information was being collected, and research suggested that the increase in reported storms was due to improved monitoring rather than more storms actually taking place.And to cap it off, two recent peer-reviewed studies completely contradict each other. One paper predicts considerably more storms due to global warming. Another paper suggests the exact opposite – that there will be fewer storms in the future.

Over the past half-century, we have become used to planetary scares. .. late Sixties .. a population explosion .. global starvation. .. later .. the world was running out of natural resources. By the Seventies .. a new Ice Age. .. the latest scare, global warming, has engaged the political and opinion-forming classes to a greater extent than any of these. .. this fashionable belief has led the present Labour Government, enthusiastically supported by the Conservatives and Liberal Democrats, to commit itself to a policy of drastically cutting back carbon dioxide emissions - at huge cost to the British economy and to the living standards not merely of this generation, but of our children's generation, too. .. most of those scientists who speak with such certainty about global warming and climate change are not climate scientists, or Earth scientists of any kind, and thus have no special knowledge to contribute
Dozens of think tank cosponsors and hundreds of scientists will gather in an effort to “restore the scientific method” to its rightful place in the debate over the causes, consequences, and policy implications of climate change. The theme of the conference, “Restoring the Scientific Method,” acknowledges the fact that claims of scientific certainty and predictions of climate catastrophes are based on “post-normal science,” which substitutes claims of consensus for the scientific method. This choice has had terrible consequences for science and society. Abandoning the scientific method led to the “Climategate” scandal and the errors and abuses of peer review by the Intergovernmental Panel on Climate Change (IPCC)
There are those who support the view which Professor Steven Schneider expressed in 1989 about the manner in which climate science should be presented. He said "To capture the public imagination, we have to offer up some scary scenarios, make simplified dramatic statements and little mention of any doubts one might have. Each of us has to decide the right balance between being effective, and being honest" http://www.john-daly.com/schneidr.htm [nofollow]. My interpretation of that statement is that it is up to each of us to decide whether to lie or not. This is expected of politicians and those who earn their living through the media but not of those in a position of trust like physicians and researchers
There is a huge amount of politics involved here
I hope that one upshot is a re-examination of our use of resources and energy
