Rising ocean temperatures, particularly during El Niño years, could trigger another marine heatwave in California, with potentially devastating consequences for marine life and local industries. Given the lingering impact of the last El Niño from 2014 to 2016, scientists are concerned about the next one, predicted for later this year.
According to Laura Gill from the Marine Mammal Center, climate change is forcing the food sources of seal pups to move further offshore, leading to malnutrition among the younger pups. Rare occurrences like gray whales swimming near the San Francisco-Oakland Bay Bridge and a dead gray whale washing up on Angel Island may also be linked to climate change.
Joshua Smith from the Monterey Bay Aquarium highlighted that the last marine heat wave led to an explosion in sea urchin populations, causing widespread depletion of kelp forests. Moreover, rising ocean temperatures during El Niño years can significantly impact fishing industries, as evidenced by the decrease in sardine populations in 2015 that led Washington to declare a federal disaster.
As advocates of environmental law, we support measures to address the effects of climate change on marine ecosystems. Legislative action that encourages climate solutions is vital. Meanwhile, individuals can also make their contribution by avoiding single-use plastics, choosing sustainable seafood, and participating in ocean restoration initiatives. This situation calls for a concerted effort from lawmakers, environmental professionals, and the public to protect our oceans and marine life from the escalating effects of climate change.
