Just when you thought it couldn’t possibly get much …
FIRE-EARTH Models show unprecedented surges in atmospheric CO2 concentrations starting 2014. The massive increases could be as much as 10 – 15 times any rises ever recorded.
To minimize abuse of this forecast by the usual culprits and dozens of newcomers, FIRE-EARTH won’t release further details at this time.
The graph shows recent monthly mean carbon dioxide globally averaged over marine surface sites. The Global Monitoring Division of NOAA/Earth System Research Laboratory has measured carbon dioxide and other greenhouse gases for several decades at a globally distributed network of air sampling sites [Conway, 1994]. A global average is constructed by first fitting a smoothed curve as a function of time to each site, and then the smoothed value for each site is plotted as a function of latitude for 48 equal time steps per year. A global average is calculated from the latitude plot at each time step [Masarie, 1995]. Go here for more details on how global means are calculated.
