'Global warming started over 100 years ago': New temperature comparisons using ocean-going robots suggest climate change began much earlier than previously thought - Ted Thornhill - Daily Mail - It’s widely believed that global warming began in the 1970s, but new ocean temperature readings show that the Earth has in fact been warming for far longer.
A study by the Scripps Institution of Oceanography in San Diego traced ocean warming to the late 19th century, which implies, say researchers, that the Earth’s climate as a whole has been heating up since then.
The report is the first global comparison of temperature between the historic voyage of HMS Challenger between 1872 and 1876 and modern data obtained by ocean-probing robots now continuously reporting temperatures via the global Argo program.
