No, never heard of this, I'd like to look at it anyway, can you dig up a link to something about it?
As someone posted a meme today, I should have saved it to steal it, "if you think the news is bad these days, you should see history".

That meme was brilliant. Yes I’ll definitely hunt around for those links for you 😊 it may take me some time but I’ll have a full go at it.
Found it!
It was Janet Yellen who posted it first 
I also follow that account, yeah, it's a great meme.
Yep, that's the same deal as with Maghreb, north africa, prior to the Dryas, which washed it away, and then a little later, airbursts from large meteorites passing burned what survived for 1200 or so years after the big event, simultaneously as it formed the Sahara it cleared up all the soot still in the air and brought on a period of warming after a nuclear winter.
Most likely also Indonesia and India were also major sites of this. Actually, come to think of it, probably also Siberia, which prior to the event that started the Dryas, minor ice age, nuclear winter, did not have the broken crust that now forms the base of Lake Baikal, it was also a temperate/subarctic rainforest.
It is probable, in my opinion, that all of the rainforests on the planet were fostered into existence or amplified by humans who understood the carbon cycle.
It's so interesting and not something I've looked deeply into, but something that I think is quite wonderful. Definitely going to read more
