"The worst-case scenario sees temperatures rise by 5 to 8 degrees (Celsius) until 2100, while rainfall will decrease between 15 percent and 20 percent," said Jose Antonio Marengo, a meteorologist with Brazil's National Space Research Institute. "This setting will transform the Amazon rain forest into a savanna-like landscape."
A more optimistic scenario from the scientists involves governments taking more aggressive actions to halt global warming by limiting greenhouse gasses.
Across the globe in Asia, the Chinese government has issued a report that recognizes significant climate change in the region. The report went on to state that global warming could wreck havoc on China's agricultural economy – possibly causing large output declines.
