Can somebody tell me how it is +20 degrees Celsius in Sweden on the first of October?

Global warming is an increasingly real threat to the ecosystem of the planet. My first year in Colorado back in 2009, there was a snow storm in October. Today is the first day we have had snow in Denver and it was warm and sunny up until now. I'm not complaining since I haven't enjoyed the winters here compared to what it was like in California. There the heat is almost unbearable in the summer on the east side of the San Fernando Valley, but I like the warm summer weather in Colorado on the east side of Denver.
