This is just the natural variability of the weather we are all experiencing.
A lot of people have "drank the Koolaid" about CO2 and its effect on global warming. It turns out that the flatulence of cattle (methane) has contributed about 5 times as much global warming effect as all of the CO2 released by all of the transportation sector -- except the politicians cannot tax or control flatulence in cud-chewing animals. The other large contributor to global warming is .... regular water vapor.
Hey, thanks for selecting my reply as best answer regarding the strange weather patterns. Cheers, AnonymousButCandid
Because the world is ending. Boo hoo.
The natural warm cycle peaked in the 1990s. We are rapidly drifting down into another natural cold cycle or ice age.
