Shifting rainfall patterns, especially those exacerbated by climate change, could drive large parts of the Amazon rainforest to become drier savanna, a new study has found. Rainfall acts like a…
337,427 square kilometers of Amazon forest were degraded between 1992 and 2014 ¬(mostly due to logging and understory fires), compared to 308,311 square kilometers completely cleared.
For two years, regions of Brazil that depend on precipitation fed by Amazonian vegetation have seen rainfall below historical averages, impacting crops and harvests. A recent bulletin from a federal agency points to agribusiness itself as one of the drivers of this pattern.
The new Science Panel for the Amazon — modeled on the UN Intergovernmental Panel on Climate Change — aims to consolidate knowledge on the Amazon rainforest and guide future public policies to conserve it.
In a step towards understanding the impending Amazon rainforest-to-savanna tipping point, scientists have quantified the knock-on effect that drought and deforestation have on each other for the first time.
Large biomes, like the Amazon rainforest, have closely linked habitats and species, which could lead to a domino effect and a rapid ecosystem collapse; even small effects can cause a crash over time.
Climate change and deforestation are forcing a rainforest-to-savanna tipping point threatening agribusiness, hydropower, and the Brazilian economy; Bolsonaro is blind to the danger.
Models and real-world events indicate that, unless action is taken now, up to 70% of the Amazon rainforest could become savanna in under 50 years, with huge carbon releases, destabilizing global climate.
Deforestation and climate change could convert Amazon rainforest to savanna by 2050. New infrastructure development would quicken process.
The Amazon worst-case scenario has arrived, say leading researchers, as predicted signs of a shift from rainforest-to-savanna begin to be seen in real time on the ground.
A 2007 study estimated that with 40% Amazon deforestation a tipping point could be reached, converting forest to savannah. New factors put that tipping point at 20-25%. Deforestation is now at 17%.
The climate zones boreal forests evolved in are moving north, and trees can’t keep up. Key species in North America’s boreal forests, like black spruce, are disappearing from areas where…
