Poor Nations to Bear Brunt as World Warms
Hmm. Let's see the assumptions you'd have to make to get here:
- There is a sustained global trend to rising temperatures (recently in the twentieth century scientists warned about the opposite).
- This global trend is in large part man-made (many climatologists the apparent warming may be a natural cyclical warming trend, swamping any anthogenic effects).
- Anthropogenic effects will be large (most credible models do have some increase in temperature due to increased levels CO2, but they vary widely on the net effect).
- Global warming will be injurious, rather than beneficial to humans (if someone proposed to create a machine that would lower global temperatures by 5 degrees, it's doubtful many would rush to turn it on. So do assume that the planet is right now at an optimal temperature for human life?)
