Climate change model wrong - again

Apparently the brilliant brain boxes behind climate change claims have had to face up to another error in their calculations.

Surprise surprise nature is not as fragile as they thought.

The naughty trees of the Amazon jungle went and found underground water that the Brains did not know about and did not die as predicted. But don't worry because in common with most discredited experts the climate change Brains have shifted the goal posts.

They claim that the Amazon will die but later than expected unsurprisingly some time after all alive at the moment are dead and unable to argue the toss.

Researchers found that during the 2005 drought, many parts of the rainforest "greened", apparently growing faster.

This finding contrasts with some computer models of climate change, which forecast that the Amazon would dry out and become savannah.

Writing in the journal Science, the researchers say it is unclear how the forest would respond to a long drought.

"We measured the changes between the drought (of July to September 2005) and an average year," explained study leader Scott Saleska from the University of Arizona, Tucson, US.

Some of the models, in particular the Hadley Centre group, became famous for predicting collapse of the Amazon and a change into savannah

Scott Saleska"And what we saw was that there was more photosynthesis going on, more capacity to take up carbon dioxide than in an average year," he told the BBC News website.

He said, however, that a climatic shift to longer and more frequent drought conditions would eventually diminish the deep-water stores, and make the trees suffer.
