I would be very interested to know which nations these are, (especially since you claim the majority are), and by what yardstick you are measuring improvement. Please feel free to provide some facts.

You’re equating the Sudan with all of the countries in Africa – which isn’t particularly correct. Most of the countries have been improving a lot over the last couple of decades compared to where they were immediately after independence.

The problem is that the climate shifts are quite likely to destabilize those to conditions like the Sudan.

However this is likely to be less of a problem than what happens on the Indian sub-continent or in the mid-west US dustbowl.

In Africa, drought continues for the sixth consecutive year, adding terribly to the toll of famine victims

Interesting, but what’s the point? The study would be more useful if it examined the impact of rising temperatures on urban crime and violence in New York, London, Tokyo and Shanghai.Or if it looked at how reduced rainfall will affect water availability and relations between farmers and communities in the agricultural regions of the west and China.

/facepalm

Yes, because further understanding and predicting how climate change may impact on political stability in already low-stability nations in Africa, and thus potential economic, political and social impacts on neighboring states and ultimately refugee flows inside Africa and so to the likes of the EU and other places is a bad thing.

And the impacts of climate change in China are probably covered by Chinese government research, some of which is probably in english and with the right search terms + google scholar should be that hard to find. Where as violence + heat waves is also probably in the literature, I think. i.e. learn to f*cking google, primarily learn to use google scholar before complaining about a hole in the literature.

Define “useful.” The difference between this kind of old cobblers and science fiction is that SF authors don’t pretend their thoughts about what might happen in the future reflect what’s actually going to happen.

Re the impact of climate change on Africa, it will very distantly trail a field consisting of the impacts of corruption, warfare, bad governance and trying to attain Western levels of population density while engaging in subsistance agriculture.

The question is really if it will cost more to mitigate the issue now, rather than to adapt to the chaos that will inevitably result as people start to starve or have vast population moves from climate shifts. That will inevitably cause conflicts at various levels. Conflict is very expensive – just look at the US bleeding itself dry in Iraq and Afghanistan.

Wake up. Democracy can’t solve this problem.
