"There are frozen (or freeze-dried) corpses of climbers all over Mt. Everest, like that of Mallory who disappeared in 1924 and was found well-preserved in 1999." Yeah, but those guys are at 25,000 ft. These mammoths were minding their own business, eating their greens and were then apparently flash-frozen for 10,000 years.
Yes, but the climate was much colder then. There were no SUVs spewing out CO2, for one thing. /s
