RCP8.5 with temperature feedback

Looking at the RCP8.5 scenario, I realised there is no climate feedback in the economic GDP model: a rising temperature does not seem to have an effect or limitation on the CO2 emissions.

Below is the calculated warming effect of the RCP scenario’s:

This is the reported negative effect on GDP, according to Richard Tol (Richard S. J. Tol, The Economic Effects of Climate Change, Journal of Economic Perspectives — Volume 23, Number 2 — Spring 2009 — Pages 29–51, figure 1):

Now to make the effect really worst case, I use the over the top red line scenario of -10% GDP per degree

Here is the result, applied to regional RCP 8.5 GDP data, all reduced to a 2005=100 value.

The funny thing is that even for Africa there still remains a net positive economic growth relative to 2005, comparable with the unabated world average!

So why limit CO2 emissions?

    Because we gotta do something!
    It’s not the worst solution there is, but is the worst we have!
