Climate Australia host Lee Constable is joined by CLEX Media and Communications Manager Alvin Stone; Research Fellow at Monash University and founder of Skeptical Science Dr John Cook; and Deputy Head of the UNSW School of Psychology Prof Ben Newell to explore the current research around communicating climate science
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.
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?
Australian researchers in the ARC Centre of Excellence for Climate Extremes have made major contributions to the 2021 IPCC Working Group 1 report, through the authorship of the report, review and the many scientific papers cited in the report.
Nerilie Abram, Australian National University; Andrew King, The University of Melbourne; Andy Pitman, UNSW Sydney; Christian Jakob, Monash University; Julie Arblaster, Monash University; Lisa Alexander, UNSW Sydney; Sarah Perkins-Kirkpatrick, UNSW Sydney; Shayne McGregor, Monash University, and Steven Sherwood, UNSW Sydney The much-awaited new report from the Intergovernmental Panel on Climate Change (IPCC) is due later today. Ahead of the release, debate has erupted about the computer models at the very heart of global climate projections. Climate models are one of many tools scientists use to understand how the climate changed in the past and what it will... View Article
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".
