Oceans’ Unprecedented 2023 Heat: Marine Life at Risk, Climate Crisis Intensifies
The year 2023 saw unprecedented marine heat waves, covering 96% of the ocean’s surface and lasting four times longer than historical averages, indicating a potential shift in ocean-atmosphere interactions. Researchers found that these events, driven by factors such as reduced cloud cover, weakened winds, and shifting ocean currents, caused significant impacts. The consequences included widespread coral bleaching, mass die-offs of marine species, and economic disruption to the fishing industry, highlighting the severity of these extreme conditions. The events of 2023 serve as a stark reminder of how rapidly ocean conditions can change.
