  3. If this was Youtube the comments would be flooded with people claiming this is false, that measurements are results of urban island effects, or jet exhausts from airplanes because all weather stations are in airports right at the spot where planes fire up their engines for takeoff etc. It’s wild.

    Very nice data and very clear trend. Sadly most politicians will continue to ignore it.
