It only took us an existential moment to damage them, but they won’t be fixed in our lifetime.

Researchers say ocean ecosystems have taken a hit from climate change – and that it could be thousands of years, not hundreds, before they recover. By analyzing layers of fossilized ocean fauna, scientists from UC Davis’ Bodega Marine Laboratory and Coastal and Marine Sciences Institute were able to make out correlations between abrupt climate change and disturbances in ocean biodiversity. Their study was published yesterday in the Proceedings of the National Academy of Sciences.

Biologically diverse seafloors can lose large amounts of dissolved oxygen as a result of climate change. The process – called deoxygenation – can disrupt the biodiv…
