一篇Hacker News帖子讨论了一篇文章,文章讲述了曾经居住在绿意盎然的撒哈拉沙漠中的一群独特的人类。 用户23提到证据表明柏柏尔人至少居住在北非12000年。 Csdvrx链接到“非洲湿润期”维基百科页面,强调了可能由全球变暖和二氧化碳增加引起的持续“绿化”。一项2003年的研究估计撒哈拉沙漠只有45%可能被植被覆盖,而2022年的一项研究表明,目前的改变可能不足以引发另一次完整的非洲湿润期,而是降低了轨道变化诱发撒哈拉沙漠绿化的门槛。

I believe current evidence is that the Berber peoples have been in North Africa at least 12,000 years.


If you find that interesting, read about the African Humid Period: https://en.wikipedia.org/wiki/African_humid_period

The present day situation is fascinating: https://en.wikipedia.org/wiki/African_humid_period#Present-d... : there is an ongoing "greening" which seems caused by global warming and CO2 increases!

However, a 2003 study estimated only 45% of the Sahara could be covered by vegetation, and a 2022 study found that it may not be sufficient to start another AHP: it just "lowers the threshold for orbital changes to induce Sahara greening"
