The planet has ice caps comparable to Earth's, they're just shown at their lowest point in both hemispheres since I was basing the colouring off this map. I used Google Earth to compare latitudes, particularly with reference to Eurasia since I hadn't really considered adding glaciers - I think I'll add some big glaciers to continent 2 since it's a bit featureless at the moment.
I'm guessing that the principle in that map style is to show each hemisphere as it appears in summer (i.e. northern hemisphere as it appears in July, southern in January). For example where I live is entirely covered in snow in winter (complete with sea ice thick enough to walk on), but it's green even further north than the Arctic circle in the summer. I think making it green on the map gives a better idea of the climate than showing it as either snow covered or half and half (since the entire country feels like one massive forest!), so I just went with that. I'm planning that kind of climate to be the location of one of the major cultural centres of the world, since it gives an interesting dynamic that fits a few ideas I've had
I think the south pole on my planet would be considerably warmer than Earth's due to the lack of a large landmass covering it, but the continents close to it would create a situation similar to our northern hemisphere. It'd also have better heat distribution because those continents would deflect the currents away from the pole, so again it'd be closer to our northern hemisphere. However, like I said before I've only looked into this a little, so my calculations could be completely wrong D:
Good point anyway, I like thinking that kind of thing through and seeing whether it makes sense or not
Thanks!
Illustrator crashed on me... but luckily I had only spent five minutes or so altering the coastlines. Time to start again...
