Study: Scientists prove human activity is the top cause of warming Antarctic waters

This article discusses how, for the first time, scientists prove human activity is the top cause of warming Antarctic waters.

t the time, Swart thought of himself as a volunteer helping further “someone else’s science.” He didn’t expect that 13 years later, the data he collected would allow him and a team of researchers to identify human activity as the number one cause of rising water temperatures in the Antarctic Ocean, also known as the Southern Ocean.

“It’s kind of nice to see it come full circle,” Swart, now a researcher with Environment and Climate Change Canada, told National Observer in an interview.

Along with other scientists from the department, and the Scripps Institution of Oceanography in California, Swart found that changes seen in Southern Ocean temperature are directly tied to ozone depletion and human-induced greenhouse gas emissions, as opposed to regular temperature variations or responses to natural climate changes, such as volcanic eruptions or changes in the sun.

Their findings were published in the scientific journal Nature Geoscience on Monday.
