IPCC AR6 Working Group 1 report: conclusions on the evolving risk of drought

September 7, 2021 3:58 pm Published by Comments Off on IPCC AR6 Working Group 1 report: conclusions on the evolving risk of drought

Drought is a major risk to Australia with extended periods of drought affecting our social, economic and environmental systems. The newly released report by the Intergovernmental Panel on Climate Change contains significant new assessments of the science and future projections of drought.

Climate Australia: Episode 3: The parched Earth

September 1, 2021 12:24 pm Published by Comments Off on Climate Australia: Episode 3: The parched Earth

Climate Australia host Lee Constable is joined by the chief investigators in the Drought team of the ARC Centre of Excellence for Climate Extremes – Prof Nerilie Abram, Prof Jason Evans and Dr Andrea Taschetto. Along the way, Lee discovers why drought is such a tricky topic to explore for climate scientists and why understanding how droughts may change in the future is one of the wicked problems of climate change.

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

What is left in the global carbon budget?

August 25, 2021 3:37 pm Published by Comments Off on 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?

BOM03: realise added value of bias correction and downscaling methods on hydrological projections

August 23, 2021 11:35 am Published by Comments Off on BOM03: realise added value of bias correction and downscaling methods on hydrological projections

Hydrological impact studies analyse the effects of climate change on hydrological variables, such as changes in soil moisture, streamflow or hydrological extremes. This project aims to investigate the realised added value effect of model bias correction and downscaling methods on hydrological projections for Australia.

BOM02: Impacts of hydrological extremes using machine learning

August 23, 2021 8:36 am Published by Comments Off on BOM02: Impacts of hydrological extremes using machine learning

This project will explore the use of supervised and unsupervised statistical learning methods (such as neural networks, random forest, clustering) to understand the impact of climate change on hydrological extremes and/or to simulate downstream impacts on affected sectors, such as agriculture, energy, transport, water resources management.

UMELB01: Visualising Victoria’s droughts

August 18, 2021 11:39 am Published by Comments Off on UMELB01: Visualising Victoria’s droughts

In this project you will be addressing the challenge of recurring droughts by helping us build a collection of data visualisations to tell the story of Victoria’s parched history. Your collection will help us understand these droughts were experienced by people across the state, and how our understanding of drought is changing as we move into a warmer world.

MON02: Characteristics of the southern HEMISPHERE jet stream

August 18, 2021 11:27 am Published by Comments Off on MON02: Characteristics of the southern HEMISPHERE jet stream

The jet stream is a band of strong westerly winds in the upper atmosphere. Shifts in the jet are associated with shifts in the storm tracks, with associated changes in regional weather and rainfall. This project will look at methods to characterise the position and strength of the jet stream in the Southern Hemisphere, with a focus on changes in the Australian region with time.

MON01: Will ANTARCTIC OZONE HOLE RECOVERY affect australian rainfall?

August 18, 2021 11:26 am Published by Comments Off on MON01: Will ANTARCTIC OZONE HOLE RECOVERY affect australian rainfall?

Ozone depletion over Antarctica from the late 1970s to 2000 has been linked to changes in the surface climate over the Southern Hemisphere in summer, among them a more positive Southern Annular Mode (SAM). Over Australian latitudes, a more positive SAM is associated with increased rainfall over eastern Australia in the summer season. Given stratospheric ozone over Antarctica is projected to recover to 1980 levels by ~2050, the impact of ozone recovery on its own would be to reduce this upward trend in summertime rainfall over eastern Australia.

UTAS01: data collation of the climate-cooling gas dma in antarctic snow, sea ice and UNDERLYING sea water

August 18, 2021 9:29 am Published by Comments Off on UTAS01: data collation of the climate-cooling gas dma in antarctic snow, sea ice and UNDERLYING sea water

Dimethyl sulfide (DMS) is a biogenic source of sulfate aerosol that influences the climate system by reducing solar radiation and altering cloud properties. Recent observations suggest that DMS may play a dominant role in the aerosol and cloud formation along the Antarctic coast where DMS is produced by marine microbes that reside on top, in, and under sea ice. However, the role of DMS remains unclear especially over the regional scale, partly due to the lack of compilation of DMS data.
