Oceans Have Been Warming For At Least 135 Years
It must have been all those 19th century SUV's.
Roemmich and his colleagues compared Challenger temperatures with data from the modern-day Argo project, which uses 3,500 free-drifting floats to measure the temperature and salinity, or salt content, of the world's oceans every 10 days. The comparison showed a 1.1-degree Fahrenheit (0.59-degree Celsius) temperature increase at the ocean's surface over the last 135 years, a result corroborated by a large body of sea-surface temperature data that goes back more than 100 years.

"That is a substantial amount of warming," Roemmich told LiveScience. Ocean warming has been previously linked to glacial melting and mass coral bleaching.
