Over the past several years the earth's oceans, that cover 70% of the planet's surface, have dramatically warmed. In a paper published last week in Advances in Atmospheric Sciences researchers concluded for the sixth consecutive year ocean temperatures in 2021 reached record levels. Compared to 2020, 2021 ocean temperatures were 14 zettajoules (14 followed by 21 zeros) warmer. This amount of energy is 145 times greater than the world's annual electricity generation - equal to a half a zettajoule. Warming oceans can/do essentially explain or account for human-caused (Anthropocene) global warming, oceans absorb 90% of climate-crisis related warming, the climate crisis in sum and resulting human health harm. Sadly however this reality is seldom if ever discussed in health care policy circles. For example, the only mention of rising ocean temperatures and/or resulting health effects in Health Affairs is my discussion in my December 2018 Health Affairs Blog post on climate crisis-caused health effects.
