"A new US-led study, featuring research by Tasmanian scientists, has concluded that warming ocean temperatures over the past 50 years are largely a man-made phenomenon."

"Researchers from America, India, Japan and Australia say the study is the most comprehensive look at how the oceans have warmed.

The study, published today in the journal Nature Climate Change, examined a dozen different models used to project climate change, and compared them with observations of ocean warming over the past 50 years."
