By the end of the third year the trees had relead more than two-thirds of the carbon dioxide they had stored during the whole of their lives, accelerating climate ge. This study shows that Amazonia ot withstand more than two cutive years ht without breaking down.
This immen forest tains 90 billion tons of carbon, enough to ihe rate of global warming by 50 per t.
In 2006 the Amazon appears to be entering its d successive year ht, raising the possibility that if the drought ti could start dyi year. Mega-fires are expected to rapidly sweep across the drying jungle. With the trees gohe soil will bake in the sun and the rai could turn into dert. This would spread drought into the northern hemisphere, including Britain, and could massively accelerate global warming with incalculable quences. Spinning out of trol this process could end in the world being uninhabitable – for the Amazon is the earth’s largest CO2 sink.
After issions caud by humans, deforestation is the d principle cau of atmospheric carbon dioxide. Deforestation is responsible for 25% of all issioering the atmosphere, by the burning and cutting of about 34 million acres of trees each year, equivalent to the area of Italy.
