That's the beauty of Global Warming Theory, it's extremely robust with respect to data - all observations confirm it with probability 1.0.
Rain, snow, drought, hail, heat wave, cold snap, temperate or harsh weather, it matters not. All are triumphant "confirmations" of Global Warming. (Currently being rebranded as "Climate Change".)
As it turns out global warming also causes global cooling haha, thus the necessity of a new catch phrase. One thing we can be sure of is that the climate will always change, thus the enviro-socialists win either way. This junk works on John Q Public because a)Everybody has been stuck in traffic behind an exhaust spewing truck. b)It’s a secular religion that fills a void in the live of Hollywood celebrities and failed Presidential candidates.
