ABC The Science Show: Oceans are becoming hotter, long-term trends show
Ocean heatwaves are intensifying, with all Australian waters warmer in winter 2025 and heat-linked events like algal blooms emerging. Professor Matthew England warns that a major Atlantic current (AMOC), which helps regulate climate and support marine life, is slowing with global consequences.
Science: Governing novel climate interventions in rapidly changing oceans
Editor’s summary
Global warming is causing substantial, rapid changes in our oceans. Attempts to adapt to these changes have already involved a host of marine-climate interventions, but to what effect? Morrison et al. reviewed the evidence and concluded that the marine governance systems meant to ensure that climate goals remain achievable and that societal and ecosystem risks are minimized have failed to keep pace with mitigation efforts. Intervention-specific principles need to be embedded within governance at all levels to avoid the worst risks associated with deploying new marine-climate interventions at scale. —Jesse Smith
Joint media release Australian Federal Government: Delivering better marine heatwave outlooks
The Albanese Government is supporting the rollout of a new long-range marine heatwave forecasting system, developed by the Bureau of Meteorology and CSIRO. Launching publicly in the 2025/26 summer, the outlooks will predict ocean temperature extremes up to three months in advance to help protect marine ecosystems and support fisheries, aquaculture, and climate resilience planning.
Great Barrier Grief: scientists face mental health battle – Cosmos article by Denise Cullen
Climate change is taking a toll on scientists’ mental health, with many experiencing distress from witnessing environmental decline. Marine ecologist Gretta Pecl says this emotional response is rational and promotes “active hope” as a way to stay engaged. She also leads initiatives to support researchers coping with climate grief.
ABC North and West SA: Race to understand Giant Australian cuttlefish behaviour as algal bloom looms
In short:
Marine scientists and wildlife authorities are undecided about how to mitigate the impact of the algal bloom on cuttlefish eggs in the Upper Spencer Gulf.
Temporarily moving the hatchlings is one option, but could lead to unintended consequences.
What next?
Ecologists say the ideal time to relocate the cuttlefish eggs would be in the next few weeks.
Sea Change at the NESP Climate Adaptation 2025 Conference

Sea Change at the Australian Recreational Fishing Forum 2025
Professor Gretta Pecl AM and Olivia Johnson were thrilled to attend and lead an engaging workshop last week at the 2025 Australian Recreational Fishing Forum hosted by the Australian recreational fishing foundation on the beautiful Gold Coast!
Scientists release seven-point plan to tackle SA’s ‘catastrophic’ toxic algal bloom
In response to South Australia’s devastating toxic algal bloom, scientists have released a seven-point plan urging urgent action, including $10 million for impact research, ecosystem restoration, emissions cuts, and a disaster-response framework. The bloom, linked to climate change, has killed hundreds of marine species and prompted a Senate inquiry and $28 million in federal and state funding.
Sea Change at AMSA Conference 2025 Naarm, Melbourne, Victoria
The Sea Change Australia team made a strong showing at the 2025 AMSA conference in Naarm, with Dr Julia Santana-Garcon presenting on climate resilience in fisheries, Professor Gretta Pecl joining a panel on “Why Oceans Matter!”, and team members A/Prof Emily Ogier and Dr Scott Spillias sharing insights on marine governance and AI-driven ecosystem modelling.
