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.

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…
Much of Tasmania’s World Heritage has been sculpted by ice. The extension to the area (currently under debate) adds to all these values.
The debate around Tasmania’s controversial World Heritage extension, under review this week at international talks in Doha, has centred on forests. But the area includes far more than “just” trees — including…
Volcanoes can help life survive in the cold.
Antarctica was once covered in lush, subtropical forests, inhabited by diverse plants and animals including large dinosaurs. That’s going back many millions of years. These days, Antarctica is 99.7% covered…
A decade-long research project has revealed the diets of extinct Antarctic megafauna – as well as uncovering potential reasons…
New research on the effect of glacial-age icebergs on the global ocean conveyor belt contradicts common hypotheses of how…
The missing link in the demise of the last ice age has been uncovered in stalagmites hidden deep underground in Indonesian…
Let’s start an ice age.
A volcano in Indonesia may be the location of a massive “mystery eruption” that has perplexed volcanologists for decades…
A commonly-held belief for many years - that 90 million years ago, a continental ice sheet formed during the Late Cretaceous…

A previously unknown canyon has been discovered in Greenland, hidden beneath the ice. It is at least 750 kilometres long…
Antarctic warming began at least two, and perhaps four, millennia earlier than previously thought, the study found.

The Antarctic warming that signalled the beginning of the last ice age melt may have actually started between between two…
