One of the wild cards in
climate change is the fate of the
Amazon rainforest. Will it shrivel as the region dries in a warming
climate? Or will it grow even faster as the added carbon dioxide in the atmosphere spurs photosynthesis and allows ...

What will be the effect of global warming on the
Amazon rainforest? Over the last 30 years, forest fires, most of them deliberately started to clear land by cattle ranchers and soy farmers, have destroyed thousands of square miles of forest. This ...

Faster plant growth due to higher concentrations of carbon dioxide may offset increased emissions from forest die-off in the tropics, asserts a new study based on
climate modeling.
The research, published this week in the journal Nature, ...
