The pygmy right whale,
Caperea marginata, at sea.
Fossils of a whale thought to be found only in southern waters have been discovered at two sites in the northern hemisphere.
Sea ice trapped atmospheric carbon dioxide in the last ice age.
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.
The Mt. Takeha volcano in west Antartica rises more than 2,000 metres above the surrounding ice sheet.
18,000 years ago a volcano in Antartica began erupting – and didn't stop for 192 years.
Scottish beeches – the slowest invasion in history?
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.
Senator Jacqui Lambie, speaking on Q&A.
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.
Fire significantly added to our ability to change the world.

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.
Glaciers have been a major contributor to sea-level rise.
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.
Coral bleaching in March 2016. Rapid rises of greenhouse gases in the past have been linked to major extinctions in the oceans.
XL Catlin Seaview Survey
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.
Million-year-old ice likely lies more than 3km below Antarctica’s surface.

Ice cores tell us vital information about how the world's climate has changed - and how it will change in the future.
Floods during warm periods of human history likely inspired the Noah’s Ark myth.

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.
Between a rock and a hard place.
Scientists have figured out how microbes may have found food when trapped beneath ice for millions of years.
Not too hot, not too cold, but just right.

Emperor penguins are adapted to the bitter cold of Antarctica, but a new study reveals that during the last ice age it got too cold even for them.
We were doing just fine before the oceans got involved.
Charles R. Knight (1916)
It’s well known that carbon in the atmosphere is causing global warming. What is less well known, outside of scientific circles at least, is the role oceans have to play in this. Our seas contain 60 times…
Aboriginal stories say Fitzroy Island on the Great Barrier Reef was connected to the mainland. It was, at least 10,000 years ago.
In the beginning, as far back as we remember, our home islands were not islands at all as they are today. They were part of a peninsula that jutted out from the mainland and we roamed freely throughout…
The polar vortex played havoc with Niagara Falls (and much of the rest of North America too).
A string of events earlier this year provided a sobering snapshot of a global climate system out of whack. Europe suffered devastating floods, Britain’s coastline was mauled, and the polar vortex cast…
