Youth For Climate 3

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.

The term 'microplastic' was coined just 18 years ago, but already they seem to be just about everywhere. Each year, the average human consumes an estimated 74,000 particles of plastic with unknown health effects. In March of this year, scientists announced they'd found microplastics flowing through our very veins.

A new analysis of flash droughts finds that droughts coming on suddenly seem to be striking faster in the last two decades, with approximately 33–46 percent of flash droughts now emerging within just five days.

Patagonian ice fields are among some of the fastest-melting glaciers on the planet. As these glaciers disappear, the earth that once lay beneath them is rebounding upwards at rates much faster than expected.

ome problems are so big, you can't really see them. Climate change is the perfect example. The basics are simple: the climate is heating up due to fossil fuel use. But the nitty gritty is so vast and complicated that our understanding of it is always evolving. Evolving so rapidly, in fact, that it's basically impossible for humans to keep up.

If Earth had a pulse, it might be The Atlantic Meridional Overturning Circulation (AMOC) – a swirl of ocean currents that carries tropical heat north towards polar waters. Over the past century this global heartbeat has eased, slowing to a speed not seen in more than a millennium. New research based on a range of indices has now bolstered views that the weakening isn't a trivial one, and critical transition is imminent.

Abrupt disruptions to Earth's climate thousands of years ago that caused extreme sea-level rise and mass ice cap melting can serve as an early warning system for today's planetary tipping points, according to new research.

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.
