Neanderthal faces were not adapted to cold

From Physorg

"Neanderthal faces had prominent cheekbones and wide noses previously thought to have developed in extremely cold periods because large sinuses were needed to warm air as it was inhaled. One problem with this theory is that modern people such as the Inuits, and other mammals living in Arctic regions have not developed large sinuses, and their sinuses are often smaller, and another problem is that it has never been proven that Neanderthal sinuses were larger."
