The successful applicant will investigate the ability of the current CMIP6 class and higher resolution climate models to capture these processes, for example, the connections between tropical convection and extratropical waves and how these processes have and will change in response to anthropogenic climate change.

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.

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 to 1.5°C, regardless of whether that target remains feasible or not.

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.

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 dioxide climate once equilibrium of the climate has been reached.

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”.
