Oceans are absorbing nearly unfathomable amounts of heat, and higher temperatures boost the odds of a marine heat wave occurring and persisting. Human warming of the planet is likely to blame. As researchers concluded in a recent study on marine heat waves in this region, “[temperature] forcing by elevated greenhouse gases levels has virtually certainly caused the multi-year persistent 2019–2021 marine heatwave.”
