Desertification, drought, and despair—that's what global warming has in store for much of Africa. Or so we hear.
Emerging evidence is painting a very different scenario, one in which rising temperatures could benefit millions of Africans in the driest parts of the continent. Scientists are now seeing signals that the Sahara desert and surrounding regions are greening due to increasing rainfall. If sustained, these rains could revitalize drought-ravaged regions, reclaiming them for farming communities.
This desert-shrinking trend is supported by climate models, which predict a return to conditions that turned the Sahara into a lush savanna some 12,000 years ago...

Scientists are now seeing signals
Which scientists and in which sphere?
BQ, exactly, only a certain band of the earth is habitable, the rest being too hot or to cold. If it heats up a bit, then some of the cold areas will become habitable and some of the already hot areas might indeed become inhabitable.
As others have pointed out, the average temperature difference between Helsinki and Jakarta is about twenty degrees C anyway, so that band appears to be fairly wide.
JH, I dunno. The article might or might not have as little foundation as a lot of other 'research'.
Like it was 12,000 years ago - damn those irresponsible neanderthals chasing mamoths in their SUVs!
