Humanity is destroying Earth’s ability to support complex life. But coming to grips with the magnitude of the problem is hard, even for experts.
66 million years ago, birds survived the calamity that wiped out all prehistoric dinosaurs. But could birds once again evolve into their long lost ancestors?
When the dinosaurs went extinct, some species took over the world. Adaptability, not survivability, explains why.
New research on the Late Devonian extinction suggests the ozone layer could be naturally depleted as the temperature rises.
The trajectory of the Chicxulub asteroid led to the most efficient release of gas and projectile rocks – which was disastrous for life on Earth.
Large numbers, huge ranges, and adaptibility make the human species very difficult to eradicate
A drying climate and the arrival of people together finished off Australia's megafauna.
300,000 years ago, there were lots of different species of human. Now it’s only us – and we're probably the reason why.
Populations of plankton are in decline. If we push this critical foundation of the marine food chain to extinction, we could cripple ecosystems for millions of years.
Every cloud has a silver lining – even the debris cloud from an asteroid impact
The island of New Guinea is home to 6% of the world’s frogs, but if the deadly chytrid fungus invades it could cause a mass extinction.
A new movie highlights the importance of radical hope and courageous action in responding to the climate crisis
Alarm bells went off when several recent studies reported mass insect die-offs in different parts of the world. But reports of an 'insect apocalypse' have been greatly exaggerated.
Australia is losing mammals faster than any other country, as well as plenty more plants and animals besides. Extinction is theft from future generations – it's time to treat it as such.
More evidence that the asteroid hit on Earth that marked the end of the dinosaurs could have triggered a deadly increase in volcanic activity.
Local tetrapod biodiversity exploded after the dinosaurs, but has barely changed in 60m years.
The natural world depends on insects to function, but they may be the next casualty of climate change.
Climate change threatens to cause mass extinctions – but how, exactly? New research suggests male fertility may be the weakest link.
The movement to kickstart a radical transformation of our society has begun. For the sake of our children – and their children – it must succeed.
Lee's research identified the cause of mysterious and devastating mass frog extinctions that spread across the world starting in the 1970s: it was a skin fungus.
