The Amazon rainforest faces the risk of reaching a tipping point, potentially triggering a widespread collapse with significant consequences for the global climate. A recent study published in Nature, conducted by an international research team that includes scientists from the Potsdam Institute for Climate Impact Research (PIK), indicates that as much as 47% of the Amazonian forest is under threat. The study identifies critical climatic and land-use thresholds that must not be surpassed to [...]

Offspring of rats that consume excessive amounts of fructose develop disturbances in the autonomic nervous, cardiovascular and metabolic systems at an early age, increasing the risk of chronic diseases such as diabetes and obesity in adulthood, according to a study conducted by Brazilian scientists. An article on the study is published in the International Journal of Obesity. The findings confirm information in the scientific literature regarding the appearance of metabolic [...]

A major study by scientists has claimed that the Amazon rainforest could hit a tipping point by 2050 due to deforestation, water stress, and climate change. The study published in Nature on Wednesday claimed that 10–47 per cent of the forest would be exposed to compounding stressors by 2050.

PARIS, Feb 15, 2024 (BSS/AFP) - 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 stabilise the global climate by storing the equivalent of around two decades of emissions of planet-warming carbon dioxide. But stress from deforestation, [...]

The Amazon rainforest could approach a tipping point, which could lead to a large-scale collapse with serious implications for the global climate system. A new Nature study by an international research team including scientists from the Potsdam Institute for Climate Impact research (PIK) reveals that up to 47 percent of the Amazonian forest is threatened and identifies climatic and land-use thresholds that should not be breached to keep the Amazon resilient. "The Southeastern Amazon has [...]

The Amazon rainforest is on course to reach a crucial tipping point as soon as 2050, with devastating consequences for the region and the world's ability to tackle climate change, according to a new study. The Amazon has proven resilient to natural changes in the climate for 65 million years, but deforestation and the human-caused climate crisis have brought new levels of stress and could cause a large-scale collapse of the forest system within the next three decades, the study, [...]

The Amazon’s ecosystem has reached a tipping point and could flip between rainforest and Savanna-like vegetation. And unless things change quickly, 47% of ‘the lungs of the earth’ could be threatened by rising temperatures, droughts, deforestation and fires by 2050, according to scientists from the Potsdam Institute for Climate Impact Research (PIK) in Germany. The southeastern Amazon in Brazil has already shifted from being a carbon sink to a carbon source, meaning it [...]

The large size variation among cetacean species, including dolphins, whales, and porpoises, is largely explained by the activity of specific gene regions, according to a recent study by scientists from Brazil's University of Campinas Institute of Biology (IB-UNICAMP). Blue whales (Balaenoptera musculus), for example, can grow up to a giant 30 meters (98 feet) long while the bottlenose dolphin (Tursiops truncatus) usually doesn't get longer than 3.5 meters. Not only does the new [...]

There are no substitutes for native vegetation, but replacing large areas of monoculture with diversified crops in places where agricultural activities are widespread can have beneficial effects on the mammals that still inhabit the region. This is one of the conclusions of a study conducted by researchers at the University of São Paulo (USP) supported by FAPESP. They focused on the northeast of São Paulo state, where the predominant biome is the Cerrado (Brazilian savanna). [...]
