What can we expect from our future climate after looking at the 'Hothouse Earths' of the past?
A 20-year-old experiment is testing whether filling the Arctic tundra with animals could keep carbon trapped in the ground.
Humans butchered a rhino in a remote part of the Philippines 700,000 years ago, but who were they and how did they get there?
Why was one gene mutation that affects hair, teeth, sweat glands and breasts ubiquitous among ice age Arctic people? New research points to the advantage it provided for ancestors of Native Americans.
Bed bugs make us shudder and cringe. So arm yourself with the courage to learn about the biology and successes of Cimex lectularius -- as well as the ways to get rid of it.
Fossils of a whale thought to be found only in southern waters have been discovered at two sites in the northern hemisphere.
The last ice age locked atmospheric carbon dioxide into oceans, which has major implications for how the oceans and carbon dioxide may be linked in the future.
18,000 years ago a volcano in Antartica began erupting – and didn't stop for 192 years.
Beeches are 'non-native' to Scotland because they got there less than 7,000 years ago. No, really.
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?
Large birds once lived across Australia, only to become extinct around the time that giant marsupials and other megafauna died out during the Pleistocene "ice ages".
Almost half a million years ago a huge flood started breaking the apart the land bridge that joined England and France.
During a Q&A discussion about climate change, Tasmanian Senator Jacqui Lambie said it was four degrees hotter 110,000 years ago. Is that right?
The Earth's orbit has driven ice ages in the past but those days could be over.
The level of carbon dioxide in the atmosphere is rising faster than at any point in the past 55 million years.
The Game of Thrones universe could fight off those long winters – if it had an industrial revolution.
Could sea levels really rise by several metres this century. Probably not, although this century's greenhouse emissions could potentially set the stage for large rises in centuries to come.
Carbon dioxide is rising faster than any time in the past 66 million years. Rapid rises in the past have been linked to mass extinctions.
Ice cores tell us vital information about how the world's climate has changed - and how it will change in the future.
2015 will likely be a degree warmer than before people started pumping greenhouse gases into the atmosphere. The last time the world was this hot wasn't great for civilisation.
