That’s the saddening implication of a study published in Current Biology Monday. Researchers looked at what happened when a marine heat wave scorched waters off the coast of Western Australia in 2011. What they found was that the survival rate of dolphins in the area declined by 12 percent and that female dolphins gave birth to a smaller number of calves. The effects lasted up until 2017.
“The extent of the negative influence of the heat wave surprised us,” lead study author and University of Leeds PhD student Sonja Wild in a statement reported by USA Today. “It is particularly unusual that the reproductive success of females appears to have not returned to normal levels, even after six years.”

Russian officials say experts will be evaluating dozens of captive whales with the hope of ultimately freeing them from holding pens that have been internationally dubbed “whale jail.”
The New York Times reported this week that Russia’s minister of natural resources, Dmitri N. Kobylkin, said the situation is unprecedented because of the number of animals ― 10 orcas and 87 belugas ― that need to be released.
Government officials plan to meet with a group of experts, including famed oceanographer and marine scientist Jean-Michel Cousteau, to figure out the best course of action, according to the BBC.
