Summary

Over the past decade, marine scientists have reported that seawater acidified by rising carbon dioxide could cause profound, alarming changes in the behavior of fish on tropical reefs. But in a Nature paper published this week, researchers from Australia, Canada, Norway, and Sweden challenge a number of those findings. In a major, 3-year effort that studied six fish species, they could not replicate three widely reported behavioral effects of ocean acidification. Researchers say the Nature paper allays one fear about the impact of ocean acidification, but stress that climate change still poses a serious threat to sea life.
