Recent climate science suggests human civilization is on the precipice. It turns out that a purely mathematical analysis, “Evidence for super-exponentially accelerating atmospheric carbon dioxide growth,” comes to the same conclusion. he paper itself is mostly for math and statistics junkies. It is essentially agnostic on climate science. But the conclusions are as stark as any in the climate literature:
The human population is still growing at an exponential rate and there is no sign in the data that the growth rate is decreasing. Many argue that economic developments and education of women will lead to a decreased growth rate and an eventual stabilization of human population. This is not yet observed in the population dynamics, when integrated worldwide. Let us hope that the stabilization of the human population will occur endogenously by self-regulation, rather than by more stringent finite carrying capacity constraints that can be expected to lead to severe strains on a significant fraction of the population.
Notwithstanding a lot of discussions, international meetings, prevalence in the media, atmospheric CO2 content growth continues unabated with a clear faster-than-exponential behavior. On the face of this evidence using data until 2009, stabilizing atmospheric carbon dioxide emissions at levels reached in 1990 for instance seems very ambitious, if not utterly unrealistic. We are not pessimistic. We think that only evidence-based decision making can lead to progress. The present evidence gives some measure of the enormous challenges to control our CO2 emissions to acceptable levels.
