Hate to say this but the earth isn't flat & it's a lot larger than just looking around your own neighborhood. I said before & I'll say again that this global warming thing should have been called a climate change from the beginning. If it gets a bit cooler where you are & it is here as well that doesn't necessarily mean it's cooler everywhere, think about the record heat in other parts of just the U.S.. I kind of figure that if they found a Wooly Mammoth in Siberia that they were able to extract blood & get DNA from that means that it has never been thawed before & that's been awhile. The geese never leave around here so I can't put anything into that but it does seem like there are more than usual, I've also gone thru 35#s of sugar for the humming birds already so there are more of them, the little flying pigs
. Whatever it is it won't happen over a year or two but rather a gradual change so it remains to be seen.
