We were flying above Hawaii just about to begin decend to kHNL (ground OAT below >80 F) at 41,000 feet the outside air temperature was minus 65 celsius. I did hear air report at minus 70 at same altitude. If temperature up there goes that low up there then no such thing as anthropogenic global warming.
There is no such thing as warming of any kind.
We have been cooling since 1934.
