Global Warming = More Shark Attacks

, ,

The Guardian contributes a further citation to the Warmlist, which already has sharks booming and sharks moving north.

Two deaths in the waters off California and Mexico last week and a spate of shark-inflicted injuries to surfers off Florida’s Atlantic coast have left beachgoers seeking an explanation for a sudden surge in the number of strikes.

In the first four months of this year, there were four fatal shark attacks worldwide, compared with one in the whole of 2007, according to the International Shark Attack File at the Florida Museum of Natural History in Gainesville.

‘The one thing that’s affecting shark attacks more than anything else is human activity,’ said Dr George Burgess of Florida University, a shark expert who maintains the database. ‘As the population continues to rise, so does the number of people in the water for recreation. And as long as we have an increase in human hours in the water, we will have an increase in shark bites…Another contributory factor to the location of shark attacks could be global warming and rising sea temperatures. ‘You’ll find that some species will begin to appear in places they didn’t in the past with some regularity,’ he said.

But there’s really no cause for alarm, as Australian scientist Phil Chapman explains, Global Warming is over, and colder weather is probably on the way.

All four agencies that track Earth’s temperature (the Hadley Climate Research Unit in Britain, the NASA Goddard Institute for Space Studies in New York, the Christy group at the University of Alabama, and Remote Sensing Systems Inc in California) report that it cooled by about 0.7C in 2007. This is the fastest temperature change in the instrumental record and it puts us back where we were in 1930.
