Yesterday TMs report by dozens of scientists from five different government agencies looked into why forecasters did not see the drought coming. The researchers concluded that it was so unusual and unpredictable that it could not have been forecast. Climate change was not a significant part, if any, of the event.Researchers focused on six states Wyoming, Kansas, Nebraska, Colorado, Missouri and Iowa but the drought spread much further and eventually included nearly twothirds of the Lower 48 states. For the six states, the drought was the worst fourmonth period for lack of rainfall since records started being kept in 1895, Mr Hoerling said.He said the jet stream that draws moisture north from the Gulf was stuck unusually north in Canada.Mr Hoerling used computer simulations to see if he could replicate the drought using manmade global warming conditions. He could not, so that meant it was a random event, he said.Using similar methods, Mr Hoerling has been able to attribute increasing droughts in the Mediterranean Sea region to climate change and found that greenhouse gases could be linked to a small portion of the 2011 Texas heatwave.But another scientist condemned the report.Kevin Trenberth, climate analysis chief at the National Centre for Atmospheric Research, a governmentfunded universityrun research centre, said the report did not take into account the lack of snowfall in the Rockies the previous winter and how that affected overall moisture in the air.Nor did the study look at the how global warming exacerbated the high pressure system that kept the jet stream north and the rainfall away, he said.This was natural variability exacerbated by global warming, Mr Trenberth said. That is true of all such longchamp le pliage large black events from the Russian heat wave of 2010, to the drought and heat waves in Australia.Mr Hoerling noted that in the past 20 years, the world is seeing more La Ninas, the occ longchamp le pliage large black asional cooling of the central Pacific Ocean that is the flip side of El Nino. He said that factor, not part of global warming but part of a natural cycle, increased the chances of such droughts.Some regions should see more droughts as the world warms because of greenhouse gases from the burning of fossil fuels like coal, oil and gas, he said. But the six state area is not expected to get an increase of droughts from global warming unlike parts of the Sout longchamp le pliage large black hwest Hoerling added.Click to stay connected with more stories like this: Sign up here to receive news by email.Twoheaded turtle born in Texas zooA twoheaded turtle has hatched at the San Antonio Zoo in Texas and officials have named her Thelma and Louise.Boston Marathon suspect chargedA federal grand jury has returned a 30count indictment against the surviving suspect in the Boston Marathon bombings.Female teacher who had sex with pupil removed from registerA woman who had sex with a 16yearold school pupil has been struck off the UK teaching register, a disciplinary panel has ruled.Mandela responding to touch says daughterThe South African President said that Nelson Mandela condition is and he better today than he was last night.Mandela in critical but stable condition, says granddaughterNelson Mandela granddaughter has told reporters outside the hospital where he is being treated that her grandfather is critical but . in a stable condition.Boss freed by workers after pay disputeAn American company boss has been freed after a pay dispute was resolved with the Chinese workers who had been detaining him at a Beijing plant.European Commission agrees 960bn budgetA tentative deal has been reached on a sevenyear, 960bn budget that will come into effect next year, the European Commission president Jose Manuel Barroso said today. longchamp le pliage large black
