In 1988, Washington DC had a miserable hot summer, worse than normal and that year Congress was unable to recess on schedule and many of the congressmen were held over in DC for the hot weather. People like James Hansen at Goddard Institute for Space Science (GISS) in NYC had been thinking maybe "global warming" was the actual threat, and managed to obtain a Congressional hearing on that topic that very summer.
Hansen is on record gloating that he had the set point in the hearing room bumped a few degrees higher than normal, so that the congressmen could sit and sweat and fully experience "global warming". He made his point and the bandwagon henceforth was fueled by ample appropriations for research in global warming."
