“Nobody, even the so-called superpowers, can negotiate with the laws of physics,” Ypersele told the AP.
Ypersele also said that the 2030 target for controlling carbon emissions and dramatically reducing the use of fossil fuels was non-negotiable.
“It’s a question of survival for a large part of humanity, and many other species,” he said.
The scientists behind the work, presented this week at a meeting of the American Geophysical Union in Washington DC, say that the winter emissions reduce the Southern Ocean’s net uptake of CO2 by 34%, or more than 1.4 billion tonnes per year. That amount is roughly equal to Japan’s annual carbon emissions.
“The Southern Ocean is still going to be important in the global carbon cycle,” says Seth Bushinsky, an oceanographer at Princeton University in New Jersey who is leading the study. “We’re just trying to understand exactly how and why.”
The ocean’s winter CO2 emissions, which were tracked by a fleet of robotic floats, occur when deep waters rise to the surface and release centuries-old carbon. This is part of a larger process of ocean circulation that moves heat and nutrients around the globe, but researchers have struggled to pin down precisely how the overall system works, in part because of a dearth of data.
