From the people trying to convince us that the planet is overheating, a graphic and disturbing post about frostbite

Frostbite often creeps up on its victims, and is often unnoticed until the end of the day. Fingers and toes are almost always cold and numb in Arctic conditions, however experienced the traveller. Once numb the person is unaware of any further pain and may be oblivious to freezing injury. Frostbitten fingers and toes are hard, just like a sausage out of the freezer. Once in a place of warmth the frozen part can be thawed. However this must only be undertaken when there is no chance of refreezing. This is usually only possible at a basecamp or prior to evacuation. Should any of the Ice Team develop frostbite, they will not be in a position to guarantee there will be no re-freezing, and difficult decisions about treatment options would entail.

Re-warming is undertake using hot water at 38ºC for 30 –40 minutes. This can be an excruciatingly painful procedure.
