To better understand the implications of the latest climate science for Tasmania, this brief combines information from the IPCC AR6 WG1 report, with regional assessments that contributed to the UTAS Blueprint for a climate-positive Tasmania, and expertise from the Australian Research Council Centre of Excellence for Climate Extremes (CLEX). The regional information is based on Tasmania-specific downscaled modelling undertaken by Climate Futures for Tasmania.

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?
It has been an incredibly busy time for the Knowledge Brokerage Team. We've hired a graphic designer, Ally Crimp, added 3 key briefing notes, become deeply involved with industry sectors, developed our climate classrooms and so much more.
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.
Briefing note 14: The latest global climate models present challenges for generating climate projectionsJune 23, 2021 10:41 am Comments Off on Briefing note 14: 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 dioxide climate once equilibrium of the climate has been reached.
The past four months have seen the Heatwaves and Cold Air Outbreaks research program focus very much on improving our capacity to understand and help others in research and industry get an insight into the impact of extreme heat events.
Research brief: Tropical rainfall modelling errors decrease slowly, but storm resolving models may be the futureOctober 23, 2020 10:24 am Comments Off on Research brief: Tropical rainfall modelling errors decrease slowly, but storm resolving models may be the future
An international team including CLEX researchers examined models used by the Intergovernmental Panel for Climate Change (IPCC) over three model phases linked to IPCC reports – CMIP3, CMIP5, and the most recent, CMIP6, to see if they improved representation of tropical rainfall.
Research brief: IPCC review reveals climate impacts occur at lower temperatures than previously thought.October 19, 2020 1:59 pm Comments Off on Research brief: IPCC review reveals climate impacts occur at lower temperatures than previously thought.
An international review of IPCC reports since 2001 has found that as the science has improved with each report, a trend has appeared showing climate related impacts like heatwaves, the collapse of the West Antarctic ice sheet and coral bleaching are likely to occur at lower global mean temperatures than estimated in earlier reports.
In this project you will investigate the competing effects the Antarctic ozone hole and increasing greenhouse gases have on the Australian summer season rainfall, using the latest climate models. These are now available on the National Computing Infrastructure (NCI) supercomputer and are being used as input into the Intergovernmental Panel on Climate Change’s Sixth Assessment Report.
A group of international researchers using CMIP6 models to determine how heavy precipitation events will alter with climate change. The northern hemisphere in particular showed a strong warming signal for increased precipitation.
