A study published by scientists at the Monterey Bay Aquarium in February 2022 showed that the majority of the ocean’s surface has experienced extreme heat since 2014, and that these warm temperatures have been occurring with greater frequency. This overheated ocean has become the new normal: the number of marine heat days has increased worldwide by over 50% from 1925-2016. Human-caused global warming has made marine heat waves at least twenty times more likely than in the past. A warmer ocean means more energy for storms as we’ve seen in more intense hurricanes and cyclones. The that the ocean stores will continue to warm the planet long after it has been absorbed because not only does the ocean store heat, it releases heat and will continue to release heat.
Understanding that the ocean is absorbing so much heat is important because the ocean plays a central role in stabilizing Earth’s climate system. Measuring the magnitude and rate of ocean heat uptake is a very complex and challenging task that requires enormous observational and modeling effort.” Warming the Earth’s Climate System Where, how much, how quickly has the ocean warmed, and how much heat will it absorb in the future, “are questions that send satellites orbiting around the globe and take oceanographers to the far reaches of the sea. Scientists have been tracking ocean warming around the globe. By 2100, the ocean will take up 2 to 4 times more heat if global warming is limited to 2☌ and up to 5 to 7 times at higher emissions.” “To date, the ocean has taken up more than 90% of the excess heat in the climate system.
The global ocean has warmed since 1970 and the rate of ocean warming has more than doubled since 1993. Gail Grabowsky Kaaialii, Marine BiologistĪs you can see from the graph, ocean heating has risen as carbon dioxide in the atmosphere has increased.
