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.
Scientists have figured out how microbes may have found food when trapped beneath ice for millions of years.
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.
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…
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…
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…
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…
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…
A volcano in Indonesia may be the location of a massive “mystery eruption” that has perplexed volcanologists for decades, according to a new study. The eruption occurred in 1257, and it could also be one…
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. To put that in perspective, imagine a ten kilometre wide gorge, up to 800 metres…
The Antarctic warming that signalled the beginning of the last ice age melt may have actually started between between two and four millennia earlier than previously thought, a new study has found. Previously…
Retreating glaciers are proving to be good news for plant scientists. Underneath one such glacier on Ellesmere Island in Canada, researchers have found plants they believe have regrown after being entombed…
University of Hawaii at Manoa researchers have investigated preserved geological rainfall pattern clues, or “proxies”, during…
Scandinavian conifer trees in the high arctic were able to withstand the last ice age, researchers from Murdoch University…
The arrival of the first simple plants on land more than 470 million years ago may have triggered the first ice age. The…
