Receding kelp forests, jellyfish blooms and disruption to fisheries are just some of climate change’s impacts on the ocean

As bushfires raged across Tasmania, Victoria and New Zealand, and north Queensland faced a massive cleanup after unexpected flooding, a different extreme weather event was silently forming in the Tasman Sea over summer.

For the second year in a row, a stubborn high-pressure system over the Tasman Sea was warming the surface of the ocean to above-average temperatures, forming a marine heatwave, wreaking destruction and providing a glimpse of the new ecological order in the marine Anthropocene. Globally marine heatwaves are becoming more frequent and prolonged and affecting biodiversity, according to new research published in Nature Climate Change this week.
