Atmospheric concentration of CO₂
By Robbie Andrew“ Almost all the variation from week to week is natural, probably a result of shifting wind patterns bringing different air parcels to the sampling site, such that it is highly unlikely that we can discern anthropogenic effects from week to week. The steady increase from year to year, however, is clearly driven by our global emissions.” Robbie Andrew’s area and line charts are updated weekly to include the current atmospheric CO₂ concentration at Mauna Loa in Hawaii, sea surface temperature anomalies, and the global average atmospheric CO₂ concentration.
