A good old fashioned scare story from the Silly Moaning Herald, just like the good old days. Remember the cover of Al Gore’s book (see right), showing multiple hurricanes approaching the US (one even spinning the wrong way for the Northern Hemisphere…!)? Well it’s time for that scare to be recycled once again:
The number of Atlantic storms with magnitude similar to killer Hurricane Katrina, which devastated the U.S. Gulf Coast in 2005, could rise sharply this century, environmental researchers reported on Monday.
Scientists have long studied the relationship between warmer sea surface temperatures and cyclonic, slowly spinning storms in the Atlantic Ocean, but the new study attempts to project how many of the most damaging hurricanes could result from warming air temperatures as well.
The extreme storms are highly sensitive to temperature changes, and the number of Katrina-magnitude events could double due to the increase in global temperatures that occurred in the 20th century, the researchers reported in the journal Proceedings of the National Academy of Sciences.
If temperatures continue to warm in the 21st century, as many climate scientists project, the number of Katrina-strength hurricanes could at least double, and possibly rise much more, with every 1.8 degree F (1 degree C) rise in global temperatures, the researchers said. (source)
Funny that the accumulated cyclone energy is now almost as low as in the mid 1970s, when a new Ice Age was the environmental scare du jour. Apparently, 30+ years of man made warming hasn’t made much of an impact on cyclone and hurricane activity. But don’t let the facts get in the way of a good scare, eh?
