Ocean fronts act as hotspots for marine biodiversity and play an important role in regulating the Earth’s climate. As the oceans get warmer with climate change, the location, number and intensity of ocean fronts may change. This could have far-reaching implications for the climate system, marine ecosystems and global fisheries.
Artificial intelligence (AI) is increasing in popularity in the field of climate modelling. Academic publications on the topic have surged and there are more and more initiatives to support the development of research in that field. But, where does this growing interest come from?
After studying hotel management in Ecuador and conducting research on sharks in the Galápagos Islands, Denisse decided to pursue a PhD with the ARC Centre of Excellence for Climate Extremes and the Institute for Marine and Antarctic Studies in Tasmania. She is currently focusing on understanding how fine-scale changes in sea ice and ocean conditions affect Southern Ocean marine ecosystems.
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.
Knowledge brokers work at the interface of academics and consumers of climate information, sharing knowledge with the goal of facilitating communication and achieving improved outcomes for all.
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.
