Correlation, causation, and coupled pairs of differential equations

An aspect of paleoclimate evidence to which Professor Jennifer Francis alludes in her recent report on Arctic amplification is the close mutual modeling which Earth surface temperature and carbon dioxide concentration exhibit during the recent geologic past. Since relative timings … Continue reading
