Actually, there is evidence to support it. The start of the current warming trend coincided directly with the Industrial Revolution, when humans began burning fossil fuels in sizable quantities. Furthermore, I don't care what source you have for 2019 being cold, the temperature and weather of a single year has nothing to do with a climate shift.
I swear, these kind of arguments remind me of the morons who say "How 'bout that global warming, huh?" if it snows once in a year.
