Over the past few decades, the world has been experiencing more heat waves due to global warming. But what about the long-term effects of these extreme weather events on local ecosystems? Let's take a look at Jiaozhou Bay in the Yellow Sea, where scientists have been tracking heat waves for nearly seven decades.

From 1954 to 2022, researchers identified 156 heat waves in the bay. The number of heat waves has been increasing by about 0. 62 times every ten years. The total days affected by heat waves have also gone up by 6. 65 days per decade, and each heat wave has been lasting around 0. 66 days longer. The intensity of these heat waves has been fluctuating, but with shorter cycles over time.

To understand the impact on the marine life, scientists studied zooplankton abundance from 2003 to 2022 at 12 different stations in the bay. They found that zooplankton populations boomed during heat waves, particularly among copepods and gelatinous zooplankton. However, the response of plankton varied by season, indicating a complex relationship between heat waves and marine ecosystems.

This study offers a new perspective on how heat waves are shaping offshore plankton ecosystems. It's a reminder that climate change doesn't just affect temperatures; it can also reshape the life beneath the waves.
