It doesn’t get much dumber than this. Temperatures in DC on June 22 and 23, 1998 were both all time records in DC at 101 and 98. Hansen and Wirth had no way of knowing that a few weeks later it would be even hotter, arranged the hearings to coincide with the record heat, and sabotaged the air conditioner in the hearing room.
But no matter how you look at, Hansen deserves credit for healing the planet with his 1988 warnings. 1988 was the last really hot summer in the US, and ended the long standing tradition of very hot US summers.
