Earth’s thermostat can fail spectacularly at times. Around 700 million years ago, huge volcanic eruptions triggered “Snowball Earth”.

A special combination of rain, rocks and subsea volcanoes makes the sea salty.
A new study can’t rule out the possibility that human ancestors lived on Crete at the same time as they evolved in Africa.
This sudden, 150,000-year long temperature spike has many parallels with modern climate change.
Humpback whales are deterred from their migration routes by the noise of air guns used to survey the ocean floor for oil and gas deposits, a new study has found.
How can life on Earth help us understand life in space? To answer this question, we compare biological clocks and geological rocks and find that they tick uniformly.
Gas buried in the Northern Territory’s Velkerri Shale was produced in a “slime world” that existed nearly a billion years before the first complex life on Earth evolved.
You would not recognise Earth if you saw it 500 million years ago - the lands, oceans, climate and life were all very different. Scientists now have a new map of the deep history of Earth.
One of Australia’s most distinguished palaeontologists will be farewelled at a funeral in Canberra today.
Researchers are looking at whether devastating asteroid strikes are predictable or random.
Mercury found in prehistoric rock bolsters the idea that volcanoes caused a mass extinction 200m years ago.
There is a direct correlation between the age of the builder, spade size and the speed at which boredom sets in.
In the wake of the collapse of Malta’s spectacular arch, which UK coastal features are under threat from the unrelenting forces of wind and water?
Reports claim the feature has vanished – but then mountains are always changing shape.
Signals from violent earthquakes are helping reveal the landscape of the planet’s insides.
Almost half a million years ago a huge flood started breaking the apart the land bridge that joined England and France.
Are we headed to a magnetic reversal and all the global disruption that would bring? Enter archaeomagnetism. A look at the archaeological record in southern Africa provides some clues.
A new project tracks earthquakes accidentally induced by human activity. It suggests the problem is bigger than some scientists thought.
Lightning strikes are powerful – but we haven’t had solid estimates of their energy until now. Researchers turned to the hollow stone tubes they create by vaporizing sand for more precise calculations.
New research suggests how asteroids may have helped create conditions for life on Earth. But we shouldn’t get too carried away with the idea – yet.
