Well, this was the coldest summer in my memory. I don't think I've ever experienced 50 degree weather in July/August (and I used to live further north).
Oh, this is just localized. Except, wow...I've got friends over in Europe experiencing the same. Okay, perhaps it is just the northern hemisphere of Earth. I haven't checked with my Aussie and S. American friends as to whether this year was warmer or colder for them.
But if this is in fact the highest CO2, and one of the warmest global temperature years. Something is very lacking on the observable real anectdotal evidence. And yes, folks dismiss anecdotal evidence. But if anecdotal evidence is in fact in conflict with your theory. You should pause and reconsider. If you say, penguins can't fly, and suddenly see a penguin fly.....it's time to pause and re-analyze and assess whether you've discovered a new type of penguin or whether your premise is not globally valid. Perhaps one must revise to "most penguins" don't fly.
Now granted, we have not discovered any flying penguins. But we've found a lot of equivalent questionables in regards to Global Warming claims. Enough that I think there needs to be some honest re-evaluation.
