Marine heatwaves

- The oceans are full of heat, and it’s coming ashore
The oceans and land are experiencing record-breaking heat, with Western Europe and the U.S. facing deadly heatwaves in June and July. Over 40% of the global ocean is undergoing marine heatwaves, linked to fossil fuel-driven climate change, which exacerbates extreme weather and coral reef damage. Scientists connect ocean warming to intensified land heatwaves and health crises.
- The ocean has shielded us from the worst of climate change. Now it is running a fever |
The ocean has absorbed much of climate change's impact, but marine heatwaves have tripled since the early 1990s, causing coral bleaching, kelp forest loss, and ecosystem collapse risks. Karina Von Schuckmann, an IGCC author and Mercator Ocean International adviser, highlights these dangers.
- More Coral Reefs May Survive Climate Change Than Scientists Once Thought
A new global analysis suggests more coral reefs may survive climate change than previously believed, challenging the narrative of irreversible decline. The study identifies reefs with potential to withstand warmer temperatures, emphasizing the need for their protection.
- Marine heatwaves can supercharge cyclones
Marine heatwaves are shown to intensify cyclones by providing warmer ocean waters, leading to faster storm strengthening and increased damage. The study, published in Nature, highlights the link between ocean temperatures and storm severity.
