This document contains a chart from a 1988 New York Times front page, which graphs the global temperature change since 1880. The graph, created by James Hansen, a leading expert on climate change at NASA, makes clear that global warming was a well-established fact that attracted wide public attention as early as 1988. The chart was used as evidence at Hansen’s testimony hearing in the Senate, during which he stated that he was 99% certain that the warming was a result of trapped carbon in the atmosphere rather than natural variation.
