Global warming increases rain in world’s driest areas

Global warming will increase rainfall in some of the world’s driest areas over land, with not only the wet getting wetter over land but the dry getting wetter as well. New research published today in Nature Climate Change has revealed that in the Earth’s dry regions, global warming will bring an overall …

Observed precipitation datasets no better than climate models

In the climate research community it is well accepted that global climate models do a relatively poor job at capturing daily precipitation characteristics, due to the small spatial scales involved. What is far less known is that observations also suffer from large uncertainties when it comes to daily precipitation. This …

Big data reveals glorious animation of Antarctic bottom water

 A remarkably detailed animation of the movement of the densest and coldest water in the world around Antarctica has been produced using data generated on Australia’s most powerful supercomputer, Raijin. Chief Investigator Dr Andy Hogg from the ANU hub of ARC Centre of Excellence for Climate System Science worked …

Now anyone can run a climate model

In a world first, Australian researchers have developed a simple online climate model that allows anyone to deconstruct our atmosphere and environment with the click of a button and see how our world would change. The online climate model has the capacity to compute 100,000 years of simulations on a laptop computer …

The tropical steam engine: How does El Niño warm the entire globe?

by Nick Tyrrell and Dietmar Domenget This story first appeared in The Conversation Image left: Global warming by Gabor Dvornik (Creative Commons 2.0)  We regularly hear about how El Niño events raise the temperature across much of the planet, contributing to spikes in global average temperature such as the one witnessed in 1998, …

How ocean circulation changed atmospheric CO2

Scientists have struggled for the past few decades to understand why air temperatures around Antarctica over the past one million years were almost perfectly in synch with atmospheric CO2 concentrations. Both dipped down during glacial ice ages and back up again during warm interglacials. By contrast, temperature in the tropics and …

Researchers reveal when global warming first appeared

The indications of climate change are all around us today but now researchers have revealed for the first time when and where the first clear signs of global warming appeared in the temperature record and where those signals are likely to be clearly seen in extreme rainfall events in the …

Why experts refuse to debate climate

Prof Steve Sherwood’s editorial republished below, appeared in The Australian on Friday, October 28. It explains why climate scientists are avoiding debates in public forums with skeptics and discusses why the scientific peer review process is the best way to deal with questions around climate change.   Many climate scientists now refuse to take …
