WWF: Climate change speeds up Amazon's destruction

A vicious cycle of climate change and deforestation could wipe out or severely damage nearly 60 percent of the Amazon forest by 2030, said the World Wild Fund for Nature (WWF) at a press conference held at the Bali International Convention center on Thursday.

From now to 2030, deforestation in the Amazon could release 55.5 to 96.9 billion tons of CO2. At the upper end this is more than two years of global greenhouse gas emission, said Dan Nepstad, a senior scientist at the Woods Hole Research Center in Massachusetts, at the press conference.

In addition, the destruction of the Amazon would also do away with one of the key stabilizers of the global climate system, he said.

"The importance of the Amazon forest for the globe's climate cannot be underplayed," said Dan Nepstad, who is also the author of a new WWF report titled the Amazon's Vicious Cycles: Drought and Fire in the Greenhouse, which reveals the dramatic consequences for the local and global climate as well as the impacts on people's livelihoods in South America.

"It's not only essential for cooling the world's temperature but also such a large source of freshwater that it may be enough to influence some of the great ocean currents, and on top of that it's a massive store of carbon," he said.

He added that current trends in agriculture and livestock expansion, fire, drought and logging could clear or severely damage 55 percent of the Amazon rainforest by 2030. If, as anticipated by scientists, rainfall declines 10 percent in the future, then an additional 4 percent of the forests will be damaged by drought.

Global warming is in fact likely to reduce rainfall in the Amazon by more than 20 percent, especially in the eastern Amazon, and local temperatures will increase by more than 2 degrees centigrade, and perhaps by as much as 8 degrees centigrade, during the second half of the century, according to the report.

With further destruction of the Amazon forests, less rainfall in India and Central America is anticipated, as would rainfall during the growing season in the grain belts of the United States and Brazil, the scientist said.

He called for strategies to halt deforestation in the Amazon, include minimizing the negative impacts from cattle ranching and infrastructure projects to rapidly expanding the existing network of protected areas.

"We can still stop the destruction of the Amazon, but we need the support of the rich countries," said Karen Suassuna, a climate change analyst at WWF-Brazil, at the press conference. "Our success in protecting the Amazon depends on how fast rich countries reduce their climate damaging emissions to slow down global warming."

Climate change is initiating and speeding up the vicious circle. Today, carbon from forest conversion to cattle pastures and agriculture in the Brazilian Amazon is seeping into the atmosphere at a rate of 0.2 to 0.3 billion tons per year. This number can double when severe drought increases forest fires. Emissions from all Amazon countries are doubling the figures for Brazil.

"The Kyoto Plus climate agreement must include measures to reduce emissions from forests," said Hans Verolme, director of the WWF's Global Climate Change Program.

"A failure to protect the Amazon forest will not only be a disaster for millions of people who live in the Amazon region, but also for the stability of the world climate," he warned.

Established in 1961, the WWF operates in more than 100 countries working for a future in which humans live in harmony with nature.
