Fruit trees don't do well here. The only trees that do well are Birch, Aspen, Cottonwood, and Spruce. When it gets down to 50 and 60 below, the little moisture in the trees freezes and causes the tree to split open. Come spring the trees that can heal those large splits will make it. Those that don't will die. Fruit trees will not survive. I was looking at one of my big Birches next to my driveway this morning. It has a split two inches wide, and five feet from top to bottom. This one may not survive come spring, since it is sure to get worse during the winter.
Oldshooter: Stopping the demise of the Amazon Rainforest would help CO2 increases, BUT is global warming real? Do we really need to stop CO2 increases? I don't think so. The earth has been warmer before, and will be warmer again, without our intervention. One good volcano blast and we could have another year or two with no summers, like back in either the late 1700s or early 1800s. (There goes my memory again. I know it happened, I just can not remember the year.)
