WASHINGTON (AP) — On June 23, 1988, a top NASA scientist told Congress and the world that global warming had arrived. NASA scientist James Hansen predicted that 1988 would be the world's hottest year on record, thanks to the burning of fossil fuels that released heat-trapping gases.

The Associated Press is republishing a version of its report on the testimony to mark the 30th anniversary.
