English: Abstract The resilience of the Amazon rainforest to climate and land-use change is crucial for biodiversity, regional climate and the global carbon cycle. Deforestation and climate change, via increasing dry-season length and drought frequency, may already have pushed the Amazon close to a critical threshold of rainforest dieback.
The Amazon rainforest, [a] also called Amazon jungle or Amazonia, is a moist broadleaf tropical rainforest in the Amazon biome that covers most of the Amazon basin of South America. This basin encompasses 7,000,000 km 2 (2,700,000 sq mi), [ 2 ] of which 6,000,000 km 2 (2,300,000 sq mi) are covered by the rainforest . [ 3 ]
A drought is a period of drier-than-normal conditions. [1]: 1157 A drought can last for days, months or years. Drought often has large impacts on the ecosystems and agriculture of affected regions, and causes harm to the local economy.
If drought-like conditions become permanent with climate change, as some long-range climate models suggest, the Amazon biome could lose one-sixth to one-half of its area, or 1 million to 3 million ...
“If the Amazon rainforest is to avoid the tipping point, Indigenous people will have been a determinant factor," Miller said. Wildfires and extreme drought. Forest loss in Brazil’s Amazon — home to the largest swath of this rainforest — dropped 30.6% compared to the previous year, the lowest level of destruction in nine years. The ...
By Bruno Kelly and Jake Spring. MANAUS, Brazil (Reuters) -The river port in the Amazon rainforest's largest city of Manaus on Friday hit its lowest level since 1902, as a drought drains waterways ...
The drought is also the likely cause of dozens of river dolphin deaths in Tefe Lake, near the Amazon River. Dry spells are part of the Amazon’s cyclical weather pattern, usually from May to October.
In 2013 a group of scientists from the Princeton University published a study suggesting that total deforestation of the Amazon rainforest can strongly exacerbate drought conditions in the western states of the USA. According to the study "an Amazon stripped bare could mean 20 percent less rain for the coastal Northwest and a 50 percent ...
