Hotter regions don't pose a significant challenge. The specific heat of water is pretty high and swimming pools can store significant energy in their water. I don't remember the exact number but raising the temperature of an olympic sized swimming pool by a degree celsius takes megawatt hours of energy. that's a lot and a datacenter is perfect for this, even in hot climates.
