A sign of what? That we have the same weather pattern they did 80 years ago?

:lmao: Damn those weather patterns!

JJ makes a good point. If you want to raise the fear of global warming, use better statistics than this.

but we didn't have the same amount of crap in the atmosphere we did 80 years ago

let's look at something else caused by "human meddling" [in my best Dr. Strangelove voice]


As a result of the Montreal Protocol and its amendments, the concentrations of ozone-depleting substances in the lower atmosphere (troposphere) peaked around 1995 and are decreasing in both the troposphere and stratosphere. It is estimated these gases reached peak levels in the Antarctica stratosphere in 2001. However, these ozone-depleting substances typically have very long lifetimes in the atmosphere (more than 40 years).

As a result of this slow decline, the ozone hole is estimated to annually very slowly decrease in area by about 0.1 to 0.2 percent for the next five to 10 years. This slow decrease is masked by large year-to-year variations caused by Antarctic stratosphere weather fluctuations.
