Well, last winter was the coldest I remember, here in a long time, and the low temps lasted for days, which is unusual here.Lots of plants were killed, from it Paulette, they are basing that on the oceans conditions...most think that global warming has a lot to do with it...but i think we all just know about it now,from heavy population and communications. When I was a kid...I didn't know what it was doing even in Fl. But the trouble will be affording heat. I wish I still had my house. had a wood insert in my big den fireplace. Oh well.......... Stella
