"In August 2012, John Christy, a climate scientist from the University of Alabama, Huntsville, testified to the Senate Environment and Public Works Committee that the Earth is not warming.
"In part, Christy's testimony, a controversial one, was based on what he described as a problem with how surface temperatures are measured and averaged.
"Climate scientist Gilbert Compo's response to that was: Well, I'll measure those temperatures differently.
"So he set out to use an entirely different method to determine if the Earth's surface temperature had increased 1.2 degrees Celsius since preindustrial times.
"The answer: Undeniably yes."
