More Than Half of Amazon Will Be Lost by 2030, Report Warns
Climate change could speed up the large-scale destruction of the Amazon rainforest and bring the "point of no return" much closer than previously thought, conservationists warned today.
Almost 60% of the region's forests could be wiped out or severely damaged by 2030, as a result of climate change and deforestation, according to a report published today by WWF.
The damage could release somewhere between 55.5bn-96.9bn tons of carbon dioxide into the atmosphere from the Amazon's forests and speed up global warming, according to the report, Amazon's Vicious Cycles: Drought and Fire.
Trends in agriculture and livestock expansion, fire, drought and logging could severely damage 55% of the Amazon rainforest by 2030, the report says. And, in turn, climate change could speed up the process of destruction by reducing rainfall by as much as 10% by 2030, damaging an extra 4% of the forests during that time.
By the end of the century, global warming is likely to reduce rainfall by 20% in eastern Amazonia, pushing up temperatures by more than 2C and causing forest fires, the report said.
Destroying almost 60% of tropical rainforest by 2030 would do away with one of the key stabilisers of the global climate system, it warned.
Such damage could have a knock-on effect on rainfall in places such as central America and India, and would also destroy livelihoods for indigenous people and some 80% of habitats for animal species in the region.
The "point of no return", in which extensive degradation of the rainforest occurs and conservation prospects are greatly reduced, is just 15-25 years away - much sooner than some models suggest, the report warns.
Releasing the report at the UN conference in Bali, which aims to begin negotiations on a new international climate change deal, the WWF called for a strategy to reduce emissions from forests and stop deforestation.
Beatrix Richards, the head of forests at WWF-UK, said: "The Amazon is on a knife-edge due to the dual threats of deforestation and climate change.
"Developed countries have a key role to play in throwing a lifeline to forest around the world. At the international negotiations currently underway in Bali governments must agree a process which results in ambitious global emission reduction targets beyond the current phase of Kyoto which ends in 2012.
"Crucially this must include a strategy to reduce emissions from forests and help break the cycle of deforestation."
The report's author, Dan Nepstead, senior scientist at the Woods Hole research centre in Massachusetts, said: "The importance of the Amazon forest for the globe's climate cannot be underplayed.
"It's not only essential for cooling the world's temperature but 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."

We are at a crossroads
This country and this world are at a monumental crossroads. In a few short weeks, US voters will have an opportunity to beat back the forces of fascism and confront the billionaires who are rigging the economy, our media system, and our democracy, making it increasingly impossible for ordinary people to get by. We’re not just talking about the election. We’re talking about what must be done once these fascist elements are vanquished from power. We need a bolder set of solutions than what either major party has so far been willing to offer and a working-class movement ready to fight like hell for it. Trump didn't emerge from nowhere. The conditions that fueled MAGA authoritarianism were created by decades of radical neoliberal economic policies and a corrupt political system dominated by corporate interests. They slashed taxes on the super-rich, promising that the benefits would trickle down. They said giveaways to the corporate titans would make life more affordable for the rest of us. It was all bullshit. And when a bitter, betrayed populace searches for someone to blame, right-wing demagogues have little trouble finding scapegoats. People know when they're being lied to, but you won't hear any of this from the corporate media. Only independent journalism—powered and funded by people who believe in building a better world—can deliver truly trustworthy daily news. Our Fall Campaign is underway, and we need your help. To power our newsroom through the rest of the year, we need to raise $125,000 by midnight on October 31. So if you share our vision, please contribute whatever you can to sustain our work. |
