This last (possibly last) post by me extends the discussion of future effects of increased CO2 out into the next 8 millennia – roughly the same period of time over which man has developed advanced civilizations after the last glacial period which ended about 12 millennia ago.
The essence of these predicted effects are described by the Figure 1 shown below.
Figure 1. How cumulative carbon emissions are expected to set the climate thermostat for the next 8 millennia.
These predictions are based on recent calculations by Eby et at. reported in the AMS’s Journal of Climate (abstract can be seen here) using the UVIC coupled carbon/climate model. The numbers on each curve gives the total cumulative carbon emissions (in gigatons) over the time while human activities continue to emit carbon dioxide. The results described here tell us nothing that I have not emphasized before. I am sharing them with you here, because they more quantitatively and more clearly express our planet’s expected future after the Age of Fossil Fuels. [Read more…]
