Glaciers have been a major contributor to sea-level rise. Knut Christianson

What does the science really say about 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.
Floods during warm periods of human history likely inspired the Noah’s Ark myth. Noah's ark image from

Climate and the rise and fall of civilizations: a lesson from the past

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.

The ‘pre-Holocene’ climate is returning – and it won’t be fun

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. Simon Lieschke/Flickr

Tasmania’s World Heritage debate needs to look beyond the trees

Antarctic volcanoes help preserve life in the freezer

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…

Melting the Ice Age

A commonly-held belief for many years - that 90 million years ago, a continental ice sheet formed during the Late Cretaceous…
Antarctic warming began at least two, and perhaps four, millennia earlier than previously thought, the study found. NASA Goddard Space Flight Center

Last Antarctic ice age melt began earlier than first thought

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