"‘It’s a big eruption, and it’s in a bad place,’ geoscientist Ralph Keeling says of the impact on long-running monitoring of carbon dioxide in the atmosphere"
"The eruption of Hawaii’s Mauna Loa, the world’s largest active volcano, has interrupted a key site that monitors greenhouse gas concentrations in the atmosphere, officials said Tuesday.
“The carbon dioxide measurement equipment that maintains the famed Keeling Curve record lost power at 6:30 p.m. Nov. 28 and is not currently recording data,” the University of California at San Diego’s Scripps Institution of Oceanography said in a statement.
The site, selected by the late scientist Charles David Keeling as an ideal spot to measure CO2 due to its relative isolation and vegetation-free landscape, has been recording atmospheric concentrations of the planet-heating gas since the late 1950s.
The Keeling Curve — a chart that shows the steady rise of carbon in the atmosphere in recent decades, as measured at Mauna Loa — is considered a simple yet important piece of scientific evidence that human activities are transforming the Earth’s climate."
