Antarctic climate variations found to originate north of Australia
CLEX researchers have overturned a scientific paradigm that has existed for 50 years. New research published in Nature Geoscience shows the massive convection caused by the ocean just north of Australia, causes a chain reaction that is strong enough to put an almost permanent dent in the powerful winds that circle the Antarctic.

What is left in the global carbon budget?
The Paris Agreement requires countries to commit to reducing their greenhouse gas emissions to ensure that the global average temperature remains well below 2°C above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5°C. But how likely are we to meet these targets?

A List of Common Unspoken Knowledge for Postgrad Climate Students
Kim Reid offers a useful list of common unspoken knowledge for postgraduate students in the climate sciences. Hopefully, she says, this will save you some time and mistakes in the future.

Briefing note 15: Can we limit global warming to 1.5C°?
Irrespective of tipping points, climate change adaptation efforts will be less costly and disruptive to society – and will stand a better chance of success – if warming can be limited to 1.5°C rather than 2°C or higher. We therefore in no way advocate for policies that forgo pursuing the ambition to limit global warming…

Climate Australia: Episode 1 – Is climate to blame?
Prof Julie Arblaster, Prof Lisa Alexander, and Assoc Prof Gab Abramowitz discuss the research around the Attribution and Risk research program. The episode explores why we can detect climate signals in some extreme weather events and not others and the implications this has for understanding how these events may change.

The latest global climate models present challenges for generating climate projections
Climate sensitivity describes how sensitive the Earth’s temperature is to a doubling of the amount of carbon dioxide in the atmosphere. One measure of climate sensitivity for projections of future climate is the Equilibrium Climate Sensitivity (ECS). ECS is the increase in the global average temperature between the pre-industrial era and a future doubled carbon…

Developing and publishing open-source software and my experience with an open peer-review process
Navid Constantinou developed a new Julia package that provides solvers for geophysical fluid dynamics problems in periodic domains. It was also the first time he had been involved in an open peer-review process, and this experience was “mind changing”.
