The signs of weakening resilience raise concerns that the world’s greatest tropical forest – and biggest terrestrial carbon sink – is degrading towards a point of no return. It follows four supposedly “one-in-a-century” dry spells in less than 20 years, highlighting how a human-disrupted climate is putting unusually intense strains on trees and other plants, many of which are dying of dehydration.
SAO PAULO, Aug 1 (Reuters) - The number of fires in Brazil's Amazon rainforest region surged to a record high for the month of July in almost two decades, government data showed on Thursday, amid a drought in the region fanned by climate change. The Amazon, the world's largest rainforest, plays a vital role in curbing global warming because of the vast amounts of greenhouse gas it absorbs.
La destruction de l'Amazonie est un phénomène qui s’étend au-delà de la déforestation mais les neuf pays qui partagent cette ressource naturelle sont engagés à la protéger.
New research suggests 75% of the rainforest has become less resilient to stress since the early 2000s.
The Amazon rainforest is facing a barrage of pressures that might tip it into large-scale ecosystem collapse as soon as 2050, according to new research Wednesday warning of dire consequences for the region and the world. The Amazon, which holds more than 10 percent of the world's biodiversity, helps stabilize the global climate by storing the equivalent of around two decades of emissions of planet-warming carbon dioxide.
This year's heat and drought in the Amazon intensify worries that it is approaching a tipping point.

Past governments blamed the growing of coca – the base component of cocaine – for clearcutting, but a recent study shows otherwise
A community of Indigenous peoples worried that mercury used by gold miners was contaminating the fish they eat. So they created a DIY team to find out more.

For every three trees dying from drought in the Amazon rainforest, a fourth tree – even though not directly affected – will die, too. In simplified terms, that’s what researchers have now found using network analysis to understand the complex workings of one of Earth’s most valuable and biodiverse carbon sinks. The regions most at risk of turning into savannah are located on the forest’s Southern fringes, where continuous clearing for pasture or soy has already been weakening the forest’s resilience for years.
Climate tipping points in the Antarctica, the Arctic and the Amazon are at risk of being reached before or at the current level of global warming of 1.2 degrees Celsius, requiring a “major rethink” of global climate goals and the action necessary to achieve them, according to a recent report.
Climate analysts are astounded by such a high reading during the rainy season, and is the third monthly record this year
More than three-quarters of the world's largest rainforest has become less resilient to drought since the early 2000s, with areas near humans and with lower rainfall being the worst hit
The most widely publicized threat to the Amazonian rainforest is deforestation. Less well understood is that public lands are being converted to private holdings in a land grab we’ve been studying for the past decade... Much of this land is cleared for cattle ranches and soybean farms, threatening biodiversity and the Earth’s climate.
in a new study, we discovered that secondary forests across the Amazon are absorbing just 9.7% of the emissions created by the destruction of old-growth forests in the region. That’s despite these regrowing habitats occupying 28.8% of all deforested land.
Since 1988, humans have destroyed an area of rainforest roughly the size of Texas and New Mexico combined
It’s Beginning to Feel Like We’ve Finally Pushed the Planet Past its Final Tipping Point. We have “extreme events” the kind scientists have long feared. But they’ve even shocked scientists with how suddenly extreme and frequent they are. And “This is not a localised freak event, it is definitely part of a coherent global pattern.”
Climate change and deforestation have flipped a large swathe of the Amazon basin from absorbing to emitting planet-warming carbon dioxide (CO2), a transformation that could turn humanity's greatest natural ally in the fight against global warming into a foe, researchers reported on Wednesday.
A range of studies have long indicated that attention should be paid to the effects of climate change on subsystems such as the Amazon, Greenland ice or permafrost. These effects have been debated for more than 20 years. Since then, thousands of pages have been written describing their interrelationships, warning of a coming disaster. As in this article published in Nature by key figures in climate science, or this article published in National Geographic. However, despite the seriousness of the issue, mainstream media silence remains thunderous. With Ferran Puig Vilar
