The silver anniversary of Roy Spencer’s career-defining moment arrived with no expectation in March. He didn’t realize it until someone mentioned it to him.
For John Christy, he had no idea that a discovery announced in 1990 would not only still resonate 25 years later but would be at the center of a raging debate.
The date was March 29, 1990. That was the day – though unbeknownst to either Christy or Spencer – they publicly became climate change skeptics.
The scientists at the University of Alabama in Huntsville are known throughout the environmental community as being skeptical that climate change (or global warming) will have a catastrophic effect on the earth. The crux of the matter is that their research, using satellite data to measure temperatures in the atmosphere, disagrees with climate models they say that overstates the earth’s warming.
“We are in the minority, there’s no question about that,” Christy said.
