U.N. Finds No Link Between Extreme Weather Event Damages and Global Warming

March 30, 2012

The United Nations Intergovernmental Panel on Climate Change (IPCC) has released its Special Report on Extremes, which fails to find increasing property damage caused by global warming. The report also addresses property damage trends for particular types of extreme weather events, finding no link between trends in tornado damages and global warming, and no link between flood damages and global warming.

“Claims by global warming alarmists that global warming is causing more extreme weather events are highly speculative and refuted by sound science. IPCC is notorious for exaggerating the claimed impacts of global warming, yet even IPCC cannot find any link between global warming and property damage. This supports objective data showing no increase in hurricanes, tornadoes, droughts, floods, or other extreme weather events as our planet has moderately and beneficially warmed.”

“Extreme weather has been occurring in the Earth’s climate for hundreds of years. It is an inherent part of the Earth’s climate system.

“In a comprehensive paper on the global warming debate, published in 2005 in Pure & Applied Geophysics, my co-authors (Tad Murty, P Chittibabu) and I concluded that ‘the link between extreme weather and global warming is more a perception than reality. This perception is being fostered due to frequent media reports of world-wide extreme weather today.’

“A careful analysis suggests that extreme weather events are about the same today as in the 1960s and 1970s, when the Earth’s mean temperature was declining. In fact some of the extreme weather events like winter blizzards on the Canadian Prairies have declined in frequency in the last forty years. Also, tornado count on the Canadian-American Prairies has declined today, when compared to the Dust Bowl years of the 1920s and 1930s.

“Elsewhere, there is no evidence of increasing extreme weather events anywhere. In the monsoonal climate of India and south Asia, droughts and floods have been occurring irregularly with no increasing/decreasing trend as evidenced in a 200-year-long excellent data set. Worldwide tropical cyclone and hurricane activity appears to be on the decline in the last two years or so. Interestingly, cold weather extremes appear to be on the rise in Europe and North America in recent years, for which no explanation is offered by climate modelers.”
