Nature doing heavy lifting to slow carbon-dioxide rise
hotter and drier conditions leading to reduced carbon uptake. Nevertheless, the long-term change is driven by human emissions.” CO2 measurements at Mauna Loa are taken by the Scripps Institution of Oceanography at UC San Diego, and also independently by NOAA. The future scenario limiting warming to 1.5°C long-term is the SSP1.1-9 scenario.
