Too late to experience a wet Sahara, but too early to experience a wet Sahara
-
I find great pleasure in the fact that at one point in history there existed a lake megachad.
-
About 30 years ago, I read about a theory that if large volumes of seawater was pumped into reservoirs in desert areas and allowed to drain out again through canals, it would cool the desert enough to start a cycle of increased rainfall in it interior. But this requires a massive engineering effort to create all the necessary canals and reservoirs and pumping stations.
-
This is honestly such a great explanation. I have always had difficulty in remembering the Milankovitch cycles in my classes.
-
Anyone else find it funny when he mentioned Lake Megechad😂
-
Some sources I've seen mention that India would dry out during a wet Sahara. Also, India's current climate could be a preview of what North Africa will be like during a wet Sahara.
-
Sahara desert is good for the oceanic ecosystem with the sand blowing long distances bringing needed nutrients to the phytoplankton. It also gives nutrients to the plants in the Amazonas. Would be better to end deforestation there + other places and maybe just terraform the eastern and southern part of Sahara Desert
-
One of the best videos I've seen in a LONG time!
-
Incredible video, haven't been this invested in one for forever. Love to see more topics like this that sound bizarre but are very possible. Great work
-
“If human society is still alive and thriving by then…” love that we so casually question whether or not civilization will survive the following centuries
-
There is also a huge dry riverbed in Saudi Arabia. Recently discovered from satellite pictures, it was a large river that flowed from the south of the peninsular by Yemen, north into the Persian Gulf by Kuwait.
-
Love that trivia at the start, subscription is out Thx for the video
-
How glorious life would be if we still had a MEGA CHAD lake.... But Alas...
-
Megachad 😁💪🏿
-
Thank you for putting this up.
-
Strange to show a nuclear plant when mentioning greenhouse gases as they don't emit them! Otherwise, a fascinating and very well produced presentation. Thanks!
-
hehe.. MegaChad Lake should be Gigachad Lake🤣🤣🤣
-
Glad to see that you are back! I missed these videos.
-
This is the best video I have seen To the point Clear and concise
-
Rising global temperatures would not only bring back the Sahara but also the other 2 largest land masses that being Siberia and the Yukon making them fit for farming as well and opening up the Arctic for shorter routes in Ocean traffic.
