Bigger, badder hurricanes say climate scare-mongers

Wrong again

Wrong again

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?

Catastrophic increase in cyclone energy?

CSIRO: climate change to cause "fewer cyclones and smaller waves"

Al Gore's view…

From The Science is Settled Department. Three strikes for CSIRO today, and this last one is a peach, flatly contradicting all the Labor hype about more cyclones:

CSIRO research commissioned by the federal government suggests climate change could dramatically reduce the number of tropical cyclones in the Australian region and decrease wave heights on the nation’s east coast.

The surprise findings, which appear to contradict some common predictions about the impact of climate change, are contained in scientific papers on “Projecting Future Climate and its Extremes”, obtained under Freedom of Information laws by The Australian Online. [Why did it need an FOI request? Were the CSIRO hiding it under a filing cabinet somewhere? I wonder why… – Ed]

One paper, by CSIRO researcher Debbie Abbs, found rising temperatures could halve the frequency of tropical  cyclones.

“Climate change projections using this modelling system show a strong tendency for a decrease in TC numbers in the Australian region, especially in the region of current preferred occurrence,” Dr Abbs said.

“On average for the period 2051-2090 relative to 1971-2000, the simulations show an approximately 50 per cent decrease in occurrence for the Australian region, a small decrease (0.3 days) in the duration of a given TC and a southward movement of 100km in the genesis and decay regions.” (source)

So therefore, instead of imposing a carbon tax, perhaps the government should be paying us to burn coal and lessen the risk of damage from cyclones, right?

As usual, the science really doesn’t have the first clue about how the climate system works, and yet we are about to cripple our economy with a pointless carbon tax to “lessen the risks” from climate change? Facepalm.
