Ocean Surface Layer Has Warmed Faster Than Researchers Believed
The upper 700 meters of the ocean have warmed 24-55% faster since 1970 than scientists previously believed, according to a study in the journal Nature Climate Change.
“It’s likely that due to the poor observational coverage, we just haven’t been able to say definitively what the long-term rate of Southern Hemisphere ocean warming has been,” said lead author Paul Durack. Another study in the same journal found that deep ocean temperatures increased less significantly between 2005 and 2013. Both reports pointed to data gaps that made it difficult to produce accurate temperature estimates.
