My favorite was the old climate change denier shtick that the 'temperature hadn't increased in 14 years'. It was a hard tell that you were dealing with someone profound dishonest.
We had seen temperatures increase in a pretty steady trendline each year....until 1998. That year was unprecedented outlier and broke every record we had for high temperatures. In 1999, temperatures returned to the ascending trendline.
So, climate change deniers would use the outlier as their baseline. An act of dishonesty akin to trying to measure the average height of Americans and using Shaquille O'Neal as your baseline. So when 2000 was higher than 1999, 1997, 1996 and one of the hottest tempatures per year, they'd insist there was no climate change....because 1998 was still higher.
This lasted until about 2013 or so. When the trendline caught up with that massive temperature spike and outlier in 1998. Now AVERAGE temperatures is higher than this massive outlier.
And yet you'll still see, every so often, climate change deniers spew this antiquated, profoundly dishonest line....insisting there's been no temperature increases in 14 years.
