Better to be lucky then good
May. 9th, 2008 01:49 pmSo, in one of my works-in-progress, I have a throwaway line about the Sahara desert becoming the "grain basket of the world" due to changes in global climate. Well, thanks to Rand Simberg*, I find that this might in fact happen.
Rand links to an article in National Geographic about Lake Yoa in Chad. The gist of the article is that the Sahara dried up much slower then thought, changing over to desert around 4,000 years ago. Part of the operant theory for why is that monsoon rains quit coming due to global cooling. This relatively slow failure of the rains led to southern migrations (following the rain) and the blooming of agriculture via irrigation in Egypt.
Just goes to show you, it's better to be lucky then good!
* No, I still don't agree with Rand's politics, but I do find many of his posts interesting. Besides, even if one has a political stake in global warming (which one shouldn't - it's science not opinion) he's quoting from a reputable source.
