Are the temperatures you quote accurate? You state the lowest temperature as 0 degrees Farenheit. It is much colder than that in many places around the earth. You also say the lowest temperature recorded was in 1960 at 29 degrees Farenheit. This does not make sense.
The temperatures quoted you are referring to are definitely not accurate. The coldest temperature in the Northern Hemisphere ever recorded was -80 F, (i.e. 80 below zero) in Yukon Territory Canada. Antarctica is even colder than that. -129 F I think was the record for coldest ever on Earth, and was recorded in Antarctica.
The coldest temperature that is theoretically possible is absolute 0, which is 0 Kelvin. That would be less than -450 F. Scientists still haven't reached that temperature. Theoretically, at that temperature atoms cease moving entirely.
