Don't pin US tornado on climate change, UN panel head says

Yellow caution tape marks off the area surrounding the tornado damaged Moore Medical Center on May 20, 2013
Yellow caution tape marks off the area surrounding the heavily damaged Moore Medical Center after a powerful tornado ripped through the area on May 20, 2013 in Moore, Oklahoma. Pinning the deadly tornado in the US state of Oklahoma on climate change is wrongheaded, even though the world is set to see a rise in high-profile weather disasters due to global warming, the leader of a UN body said.

Pinning the deadly tornado in the US state of Oklahoma on climate change is wrongheaded, even though the world is set to see a rise in high-profile weather disasters due to global warming, the leader of a UN body said Tuesday.

Rajendra Pachauri, head of the UN-backed , said data was still coming in about Monday's massive tornado which tore through a suburb of Oklahoma City, killing at least 24 people.

"Could there be better preparedness in general? Yes. What could better preparedness have been? Well it's very difficult to say at this stage," Pachauri told reporters in Geneva.

"But one really cannot relate an event of this nature to human-induced climate change. It's just not possible. Scientifically, that's not valid," he said.

The tornado followed roughly the same track as a May 1999 twister that killed 44 people, injured hundreds and destroyed thousands of homes.

Tornadoes frequently touch down on Oklahoma's plains, but Monday's twister struck a populated urban area.

Because of the hard ground, few homes are built with basements or storm shelters where residents can take cover.

Oklahoma City lies inside the so-called "" stretching from South Dakota to central Texas, an area particularly vulnerable to tornadoes.

Experts warn that other —like last year's Hurricane Sandy in the Caribbean and United States—could strike more often due to climate change, as global temperatures rise and governments struggle to rein in emissions of which are blamed for the phenomenon.

"Changes that are taking place, and that we're concerned about, include an increase in heatwaves, both in intensity and frequency, increase in extreme precipitation events and also extreme sea-level related impacts because of the increase in Arctic sea level," Pachauri said.
