New research showing climate impacts from individual fossil fuel projects. 🥵 🔥 🌏
Woodside’s Scarborough project will increase global temps by 0.00039 C and result in millions of extra coral bleaching and hundreds of extra deaths from extreme heat.

For the first time, scientists can show the impact of gas project emissions
Fossil fuel companies and governments argue it's not possible to link climate impacts to specific projects, but Australian researchers have done the numbers.

The impacts of extreme lows in Antarctic summer sea ice are confronting. Read all about it in our new paper just out in @pnasnexus.org
A new study shows these extremes trigger cascading effects—from ocean warming to habitat loss for top predators. The findings underscore the urgent need for sustained long-term monitoring.

The speed of change that led to previous mass excitations is terrifyingly slow compared to modern change 😳
"In the case of the Permian–Triassic mass extinction, plants were unable to respond on as rapid a time scale as 1,000 to 10,000 years. This resulted in a large extinction event."
"In the case of the Permian–Triassic mass extinction, plants were unable to respond on as rapid a time scale as 1,000 to 10,000 years. This resulted in a large extinction event."
Around 250 million years ago, Earth was near-lifeless and locked in a hothouse state. Now scientists know why
The answer confirms scientists’ suspicion that when our planet’s climate crosses certain ‘tipping points’, truly catastrophic ecological collapse can follow.
