NASA first discovered a reduction in human CO2 emissions

The team's measurements showed that in the Northern Hemisphere, the rise in CO2 concentrations caused by humans

fell from February to May 2020 and recovered during the summer, corresponding to a global emissions decline of 13% to 3% for the year.

The results of the study gave a professionala boost for researchers studying the regional impacts of climate change and tracking the results of mitigation strategies, the team said. The method detects changes in atmospheric CO2 as little as a month or two after they occur, providing fast and actionable information about how human and natural emissions are evolving.

Previous studies have looked ateffects of lockdowns early in the pandemic and found that global CO2 levels have declined slightly in 2020. However, by combining data from the high-performance artificial satellite OCO-2 with modeling and data analysis tools from NASA's Goddard Earth Observing System, the team figured out which monthly changes were caused by human activities and which were due to natural causes.
