A new study released yesterday in Science Advances has provided important new information that links current starfish wasting epidemics to ongoing global warming. Lead by Drew Harvell–author of two books by UC Press–the results of observing starfish up and down the west coast warn of warming sea temperatures that may have larger implications in the future:
Timing of peak declines in nearshore waters coincided with anomalously warm sea surface temperatures. The rapid, widespread decline of this pivotal subtidal predator threatens its persistence and may have large ecosystem-level consequences.
Drew’s studies have moved beyond starfish to cover corals, abalone, and salmon, all of which have been devastated by similar wildlife diseases. In Drew’s new book Ocean Outbreak: Confronting the Rising Tide of Marine Disease, she warns that marine disease and global warming are just the so-called tip of the iceberg. Current marine diseases are attacking species up and down the food chain, and it is quite possible that in future years theses diseases may expand beyond the ocean and onto the land, causing even further problems. However, while these results paint a grim portrait, Harvell wants to make sure that her ultimate message is hopeful. Many of these diseases are caused by sewage dumping, unregulated aquaculture, and drifting plastic, so it is not too late to enact policy changes and solutions to protect our currently fragile environment.
