Are 400 ppm of CO2 the border to beginning the Armageddon, or not?
At last we arrived at 400 ppm of CO 2 in the atmosphere . Two decades of conferences, commitments and challenges don’t stop the growth of CO 2 atmospheric concentration. But we aren’t listening celestial trumpets or seeing angels armed with fire-swords down from heaven. It’s true, the predicted Apocalypse doesn’t start yet, but the barrier of two times the concentration of CO 2 of pre-industrial age is significant not to be a round number bur it had never exceeded in the last 600,000 years . However importance is that in first we are entering in ‘ terra incognita ’ with respect to fossil records, and second ours mathematic climatic models are out too of confidence interval; and now anything unforeseen or expected can happen. What does it mean Terra Incognita? As I explained in: Really are temperatures stopping its rice , climate models are a set of nonlinear differential equations and as such are very conditioned to the boundary conditions; this determines the calculation in l
