It could be drier but that also depends on where the ITCV is, there’s a map on discord that shows this area would get to around 38 C on average during the summer months so it could get monsoon rains. Possibly be a Savannah climate?
Also I think it was mentioned that sea level rise would cut off as 80m not the 100m he thought, so there wouldn’t be a seaway thru Eurasia. How far would the ice go during interglacials?
Would seapole have ice at poles? Since tropical currents could move to the poles? Also how long would it take for Antarctica to speciate and have a full biome if it was moved from South Pole?
