Study Suggests New Climate Threats To California’s Oysters

In the winter, rainstorms soak California’s coastline. In the spring and summer, strong winds blow waves into the narrow inlet of the Pacific Ocean. For the briny bivalves that live in the bay, this is part of the natural rhythm of life. But now, because of climate change, the torrents of winter rain run with increasing severity, and for oysters, all that freshwater can be dangerous. Summer’s waves bring increasingly acidic water, making it harder for small oysters to build their calcium-based shells. For years, scientists have warned that ocean acidification threaten oysters, but new research from UC Davis suggests that climate change ravages the creatures in a multitude of ways.
