Thanks for the comment. Your views make me reconsider a couple of areas, namely the hot steppe close to the equator. As for huge plateau, I am divided. It isn't quite so much a Tibet, but more like Turkey/Iran - heights vary around 2500 m. Still, there's quite a bit still undetermined in my map.

I already know the reference you suggested, and a couple more. But thanks for pointing it, nervertheless.

And lastly... I'm curious about that simplification of yours (and I also like the colors in the map you posted!)
