Is the climate map for my alternate Earth accurate?

[Jdailey]

Here is a map of an alternate Earth that I've been building and rebuilding for years:

Map by Mikael Asikainen



To make things easier on all of us, myself included especially, at the bottom left is a legend on this world's elevation. The differences become most apparent when comparing this map to our map, with the blank made from the map by the DeviantArtist Concavenator:

Note that the Old World in the alternate Earth is further eastward than ours, and Australia is closer to Antarctica, and that Greenland has been rearranged to the extent that Mont Forel, its highest point, is the North Pole. Presented below is how Asikainen interpreted how these geographical differences affected the ocean currents:

And now here is how "SealBoi" imagined how the differences would affect the overall climate:

The legend in the map is as follows:

Red - hot desert, e.g. Sahara

Orange - hot/semi-arid steppe, e.g. Sahel

Light-ish blue (in the tropics) - savannah, e.g. Serengeti

Cyan-ish - tropical monsoon forest, e.g. Western Ghats

Dark blue - tropical rainforest, e.g. Amazon

Yellow-green - humid subtropical, e.g. Florida

Very pale green - humid subtropical, but drier, e.g. Northern India

Darker green (usually near previous) - like previous, but colder, e.g. Hengduan Mountains

Bright, "normal" green - temperate oceanic, e.g. Ireland

Dark green (see Tasmania) - subpolar oceanic, e.g. coastal Iceland

Pink - cold desert, e.g. Gobi

Pale orange - cold steppe, e.g. Great Plains

Bright yellow - Mediterranean, e.g. Greece

Darker yellow - the previous, but colder, e.g. Ethiopian Highlands

Light blue (in the temperate zone) - humid continental, e.g. Poland

Very light blue - that, but warmer - e.g. Iowa

Dark blue-green - subarctic/taiga, e.g. Siberia

Pale-ish purple - continental but drier, high-altitude counterpart to Mediterranean, e.g. Zagros Mountains

Dark purple - subarctic but with dry summers, rare, e.g. Brooks Range

Pale grey - tundra, e.g. Arctic Archipelago

Dark grey - ice cap, e.g. Antarctica

So using the provided information above, I ask you this one question--is the climate map, in any way, accurate?

Your current ocean current map is off in a few place. Most noticeably were Arabia and zeelandia would be. Without those right the whole map will be off.
