After studying business, travelling the world, and launching a gelato business in Chile, Catherine Gregory's love for the ocean and science led her back to Australia, where she is now pursuing a PhD on the predictability of marine heatwaves.
Navigating climate uncertainty can be challenging, especially when making decisions. 'Storylines' have the potential to make an uncertain future more tangible than numbers, and thereby better aid with planning and decision-making.
In a recent study, climate scientists showed that the modified Fosberg Fire Weather Index, a proxy for fire weather, increases across Australia under climate change, suggesting a higher chance of fires in the future. They attributed this to worsening drought conditions.
The Southern Ocean plays a crucial role in the Earth's climate system, however its intricate dynamics remain poorly understood. Co-authored by over thirty Australian and New Zealand climate science experts, a new paper shows that cross-disciplinary collaboration and community building are important for solving the mysteries of the Southern Ocean’s dynamic climate systems.
In 2015, world leaders of 195 nations agreed to limit global warming to well below 2°C above pre-industrial levels and to pursue efforts to limit the temperature increase even further to 1.5°C. While this year-long exceedance of 1.5°C doesn’t break the commitments made in the Paris Agreement, scientists warn that it does bring us closer to the red line.
Current climate models struggle to accurately represent the Southern Ocean's climate dynamics due to biases related to aerosols and clouds. Tahereh Alinejadtabrizi is a climate scientist who is working on this research problem.
Accurate projections of climate change and associated extreme events under differing emission scenarios are linked to realistic representations of the temporal variability of the atmosphere at a variety of time scales. A new paper by Shao et al. (2024) introduces a novel time variability correction method designed to diagnose and rectify variance errors across a range of time scales.
Corals are particularly sensitive to weather conditions over the Great Barrier Reef. Researchers from the ARC Centre of Excellence for Climate Extremes have found that the Madden-Julian Oscillation and the El Niño-Southern Oscillation influence weather patterns over the region, contributing to the rising threat of coral bleaching.
Ashley Huang, a passionate atmospheric scientist and an alumna of the ARC Centre of Excellence for Climate Extremes, is set to embark on her PhD at Cornell University. Here, we take a look at her career journey to date.
With climate change increasing the frequency and severity of bushfire weather, climate scientists warn that Australia could face bushfires that are even more devastating than the 2019/20 Black Summer bushfires.
