First-of-its-kind detection of reduced human carbon dioxide emissions
For the first time, researchers have spotted short-term, regional fluctuations in atmospheric carbon dioxide (CO2) around the globe due to emissions from human activities.
The team's measurements showed that in the Northern Hemisphere, human-generated growth in CO2 concentrations dropped from February through May 2020 and rebounded during the summer, consistent with a global emissions decrease of 3% to 13% for the year.
The results represent a leap forward for researchers studying regional effects of climate change and tracking results of mitigation strategies, the team said. The method allows detection of changes in atmospheric CO2 just a month or two after they happen, providing fast, actionable information about how human and natural emissions are evolving.
"Having the capability to monitor how our climate is changing, knowing this technology is ready to go, is something we're really proud of," Ott said.

Climate ‘tipping points’ can be reversed,suggests new research – but only if we act urgently
in a new study published in the journal Nature,
UK scientists say these thresholds could be “temporarily exceeded” without causing irreversible damage, provided swift action is taken. They add that the time available to act would depend on the level of global warming and the timescale involved in each tipping point.
