Senior Scientist Challenges Independent's Amazon Article

Aug. 8, 2006

On July 23, The Independent reported on the recent findings of our forest drought experiment in the Amazon, in which we reduced rainfall inputs to a hectare of forest over a five-year period. This alarmist article involved no interview, and it contains many statements that I do not support.

To clarify, our results do not show that the rainforest 'could become a desert'. In the third paragraph, the piece implies that I support the position that drought in the Amazon will lead to drought that would spread to Britain, with the world spinning out of control, becoming uninhabitable. That is simply not true.

What our work does show is that the drought we imposed caused big trees to die more than small trees, which was a surprise. We also know that the amounts of carbon that may be going to the atmosphere following Amazon droughts are probably big enough to accelerate global warming. Currently trends suggest that a big chunk of the Amazon forest will probably be displaced by fire-prone scrub vegetation; global warming will probably exacerbate this trend.

The challenges we are confronting and those that we will be faced with in the future are significant. The world's tropical rainforests will be changed in important ways by global warming. But public understanding of these processes is not served by evoking apocalyptic images. What is needed now is credible reporting and sound journalism so that the global community can act wisely.
