2021年标志着自人类有记录以来海洋温度最高，含氧量可能最低（，）。这些变化使海洋物种处于气候变化的前线。例如，海洋物种的地理分布范围比陆地物种变化得更快，经历的收缩也更多（，）。然而，气候变化是否对海洋生物构成生存威胁还不太清楚。海洋物种通常被认为比陆地物种更容易灭绝，人类造成的全球海洋物种灭绝相对罕见。在本期的第524页，Penn和多伊奇提出了广泛的模型，揭示了失控的气候变化将使海洋生物走上大规模灭绝的轨道，这将是地球历史上最严重的灭绝。此外，它们揭示了如何将全球变暖保持在与工业化前水平相比增加2 ° C以下可以在很大程度上防止这些结果。
The year 2021 marked the highest temperature and likely the lowest oxygen content for the oceans since human records began (, ). These changes have put marine species on the front lines of climate change. For example, marine species’ geographical ranges are shifting faster and experiencing more contractions than those of terrestrial species (, ). However, whether climate change poses an existential threat to ocean life has been less clear. Marine species are often considered to be more resilient to extinction than terrestrial ones, and human-caused global extinctions of marine species have been relatively rare . On page 524 of this issue, Penn and Deutsch present extensive modeling to reveal that runaway climate change would put ocean life on track for a mass extinction rivaling the worst in Earth’s history. Furthermore, they reveal how keeping global warming below an increase of 2°C compared with preindustrial levels could largely prevent these outcomes.
