Sea ice is declining at an alarming rate in Antarctica with significant implications for Australia's weather and climate. Appearing before the Committee last week, two researchers from the ARC Centre of Excellence for Climate Extremes called for increased support for Antarctic research.
Once net zero is reached, greenhouse gases start to decrease and the pace of climate change begins to slow down. But while temperatures over land are expected to begin cooling, parts of the ocean may continue to warm.
Achieving net zero emissions is essential to limit the impacts of climate change which are already being felt across the world. Once net zero is reached, global mean surface temperature will likely stabilise.
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.
