I do not think anyone cares about how many amoeba die as a result of climate change. The entire argument is about the impact on humans, because we have the capability to cause our very own extinction event.
Those humans least able to adapt are those mainly in arid areas. Not only are their economies abysmal, birthrates are high, as is infant mortality. Additionally in many areas resource wars are occurring.
International aid in most cases is hopelessly inadaquate and UN peacekeeping simply not working.
You are guilty of splitting hairs on a serious subject. You had better hope the supply chain never fails where you live because the average human after 3 days without food is a vicious annimal and society as you know it would begin to unravel quite nastily.

I think we are all aware climate is changing and not just because of increasing CO2. whether you subscribe to the view humans caused it or exacerbated it is largely irrelevant. Unless change is made to a low carbon energy source the future could become nasty. It does not matter a hoot who is causing it as far as the frontline troops are concerned. They are dying and the complacent advanced world throws a few crumbs and pontificates, apparently unable to see that what is happening in Darfur today could bring a related outcome to themselves in the future. Do you seriously think all those north african refugees are economic migrants, or could it be they are escaping from an almost inevitable early death. (Iam also fully aware that political and religious considerations have a further impact)
To further illustrate the problem I suggest you study the impact of heat stress on all the grain crops. As the average growing temperature drops, yield declines slightly. As the average growing temperature increases beyond optimum essentially yield falls off a cliff. So for advanced economies crop yields fall, soil degrades, population increases.
   Pointing the finger at those economies being profligate with resources may make you feel better but the reality is far more serious.I am afraid the western world would need to be subjected to food rationing and a touch of famine in order to concentrate minds on the problem. No one is disputing the statistics of what countries consume the most, the immediate problem is that the human impact is already being felt by those least able to help themselves.
