The title is poking fun at the people who constantly invoke the “coldest [winter, summer, day] in history” stories as proof there is no global warming:
It was so hot Monday that it broke the all-time record — and the weatherman’s thermometer.
The National Weather Service’s thermometer for downtown Los Angeles headed into uncharted territory at 12:15 p.m. Monday, reaching 113 degrees for the first time since records began being kept in 1877.
Shortly after that banner moment, the temperature dipped back to 111, and then climbed back to 112. Then at 1 p.m., the thermometer stopped working.
I was in Dallas, Texas, where it was an unseasonably cool 73. When a colleague texted me that it was 106 in Long Beach, I didn’t believe him. So I checked the Weather Channel site on my phone. He was wrong. It was 109.
It is silly to take a single day of any type of weather and extrapolate that to conclude anything about long-term heating and cooling trends. One hot day or season does not prove global warming any more than one cold day or season disproves it.
