A new study has revealed a 240% increase in marine heatwave (MHW) days worldwide during the 2023-24 summers, marking an unprecedented rise in ocean temperatures due to climate change, El Niño, and record-low cloud cover. The research, published in Nature Climate Change, shows that 10% of the world's oceans recorded their highest-ever sea surface temperatures (SSTs), reaching levels four times above historical averages. Extreme Weather and Oceanic Disruptions The prolonged marine heatwaves had far-reaching effects, influencing global weather patterns and triggering severe storms, flooding, and cyclones: Heatwaves struck the UK, North America, and Japan Severe flooding hit Ecuador, Libya, Japan, and Australia The Atlantic hurricane season saw near-record storms MHWs in...

The world’s oceans are heating up at an alarming rate, with marine heatwaves (MHWs) surging by 240% over the last two years according to a new study published in Nature Climate Change. From 2023 to 2024 nearly 10% of the world’s oceans recorded their highest-ever sea surface temperatures (SST), reaching levels four times higher than historical averages. Scientists attribute this rapid warming to human-induced climate change, El Niño, and record-low global cloud cover. The impact of prolonged MHWs has been devastating. The rising ocean temperatures contributed to heatwaves in the UK, North America, and Japan, as well as severe flooding in Ecuador, Libya, and Australia. These heatwaves also supercharged hurricanes, including Cyclone Gabrielle, which caused $14 billion in damages in New...
