Report shows increase in natural disasters

For the first time scientists say man-made climate change is causing extreme weather events like droughts, heat waves and floods.
Nearly 400 experts from around the world produced a report with evidence human activity and an increase in greenhouse gas emissions is influencing major climate events.
2011 was the year of extreme weather according to the American Meteorological Society's state of the climate report: last year seven tornados caused $1 billion of damage in the United States, there were record floods in Brisbane and cyclone Yasi hit Queensland - Australia's most powerful tropical cyclone since World War One.
For years scientists have warned human activity is creating climate change but now for the first time they've gone further - concluding it is creating more freak weather events.
“We can’t explain these events by natural variability alone, “says climate scientist Tom Karl “They’re just too rare, too uncommon.”
The state of the climate report was compiled by nearly 400 scientists in 48 countries, including Victoria University's James Renwick.
“The risks of a lot of extremes - heavy rainfall, high temperatures and heat waves associated with that, forest fires, droughts and the risks of those things are all increasing,” says Mr Renwick.
The scientists studied 50 years of data and found last year's Texas heat wave was 20 times more likely to happen because of climate change than natural variation in weather systems, and the United Kingdom’s record warm November - the second hottest since records began in 1659 - was 60 times more likely.
Scientists have long struggled with a link between individual events and climate change but they're now sure it's boosting the odds of extreme weather.

This should be made compulsory reading for the so called 'Experts'. just visit 'Breadandbutterscience.com',scroll down the page to Weather History and follow the links to "A Chronological Listing Of Early Weather Events".

Bullshit or not, we need to urgently address our treatment of the planet. People need to stop consuming and start contributing - grow a garden would be a good start, cut back on meat and plastics consumption...etc

I'm quotiong from Roger Pielke Sr.'s blog... and his "bullshit button":
A few quotable quotes from the (IPCC Special Report on Extremes) report (from Chapter 4):
"There is medium evidence and high agreement that long-term trends in normalized losses have not been attributed to natural or anthropogenic climate change"
"The statement about the absence of trends in impacts attributable to natural or anthropogenic climate change holds for tropical and extratropical storms and tornados"
"The absence of an attributable climate change signal in losses also holds for flood losses"
With this post I am creating a handy bullshit button on this subject (pictured above). Anytime that you read claims that invoke disasters loss trends as an indication of human-caused climate change, including the currently popular "billion dollar disasters" meme, you can simply call "bullshit" and point to the IPCC SREX report
