The report looked at over 1,700 documented changes in marine life. All of the data sets spanned at least 19 years, the time span that climate scientists say is necessary to confirm fluctuations are related to climate change, rather than temporary weather changes like El Niño.
The study also found that warmer temperatures are coming to the oceans earlier in the year. Marine spring events, like the temperature-driven bloom of zooplankton, take place as much as 11 days earlier than they used to.
What questions do you have about climate change’s effect on the ocean?
