The setting is a sci-fi/fantasy future Earth ( ~5 million of years in the future) so mountain chains and general elevation is more or less the same of our own Earth, just out of position due to a slightly different poles location. Major difference is the desiccated Mediterranean basin, now a +3500 mt deep (11500 ft) empty salt waste. To help you visualize the current continents in the context of this tilt here’s a map with unaltered coastlines:
The plausibility of the landmasses and features as I arranged them is not important: what I need is a general idea of the biomes and environments. Although I would like to have a general understanding of the global climate, if you can I would really appreciate a slightly more in-depth analysis of the continent highlighted in the map below (Western Europe + North-western Africa):
OPTIONAL REQUESTS: I would like to keep things as scientifically believable as possible, but (for story reasons) it would be great to have:
- Climate on the afore-mentioned continent approximating the corresponding climate of North/South America (the yellow dot in the center of the picture above is about same latitude as NY) e.g. North-western African coastline resembling more Florida in climate than Morocco
- Specifically, I would like to have a continental dry/continental humid climate (or within “European” range) on the “Italian” land bridge across the deadly salty waste that is the empty Mediterranean basin. My explanation for this according to my own researches is that the lands across the empty basin would essentially behave as a high plateau with their own climate different from that of the geographical oddity that is a 3500 mt deep dry chasm. This chasm, according to this paper about climate during the Messinian age (last time the Mediterranean basin was empty), would against expectations actually increase precipitations on nearby mountain ranges especially on the northeastern edge of the basin (ref. line 599 in the paper); rivers would eventually fall into the hollow abyss and gather as hyper-saline lakes at the bottom then evaporate, restarting this closed cycle.
- Global climate possibly resembling to some degree the Holocene climatic optimum e.g. “Green Sahara”.
Every reasonable explanation that integrates this requests is more than welcomed (but if plainly impossible I’ll just surrender to evidence). There is a lot of useful stuff in this paper about the Messinian Salinity Crisis (MSC) climate, though I honestly can’t understand most of the technical aspects but feel free to read it if you want to (jump to chapter 4. Discussion if you don’t want to read all the details).
TL;DR Can you help me setting the general climate for my world? bonus: is it possible to have a global climate resembling that of the Holocene climatic Optimum? (Or alternatively a climate on the continent depicted above equivalent to latitude to that of North/South America)
THANK YOU! Your help is immensely appreciated :)
