The duration between the equinoxes is the same six months everywhere on earth. 22-hour days are balanced out by 2-hour days, not a smaller number of days with more than 12 hours of daylight. Of course plants that need, say, 10 hours of light for 9 continuous months to mature would be in trouble, but a lot more could grow closer to the poles if it were warmer. A lot more did grow closer to the poles during the Early Eocene Climatic Optimum. https://en.wikipedia.org/wiki/Early_Eocene_Climatic_Optimum#Land https://en.wikipedia.org/wiki/Early_Eocene_Climatic_Optimum#...
