Unprecedented sea surface temperatures are driving extreme weather events and ecological crises across the country. This heatwave in our oceans contributed to intense rainfall, catastrophic floods, and an unusually active cyclone season – many storms intensifying at alarming speeds. Even inland regions like Townsville have felt the impacts, with severe flooding linked to moisture-laden systems from the ocean.

Our marine ecosystems are also paying the price. Both Ningaloo Reef and the Great Barrier Reef experienced mass bleaching simultaneously, while South Australia faced a months-long toxic algal bloom. These events underline the role of warming oceans as the climate’s “engine room,” fueling storms, floods, cyclones, and ecological collapse.

Globally, record sea temperatures have been linked to deadly hurricanes in the US, catastrophic floods in Europe, and worsening heatwaves. Scientists warn that while oceans absorb over 90% of excess heat from greenhouse gases, this crucial buffering comes at a cost – destabilising weather patterns and ecosystems worldwide.
