I'm just asking a question. Did anthropogenic Global Warming cause the Ice Age 10,000 years ago?
Did anthropogenic Global Warming cause the continents to separate?
Did anthropogenic Global Warming make my gum bleed and my right upper tooth to hurt when I drink cold water?
No, no and yes. /AGW-hysteric-mode
According to the AGW hysterics everything that's currently wrong with the world from ISIS to Putin's aggressive policies to the nor'easters on the East Coast and the "Beast from the East" in Europe, floods, droughts, . . . . is due to AGW, so surely your bleeding gums and toothache with cold water are due to AGW.
BTW, levity aside, for the sensitive tooth, order some European Synsodyne Repair and Protect toothpaste on Amazon. Unlike the US product with the same name, it actually works. I had horrible cold-sensitivity in a tooth hit while I was on sabbatical the UK, picked up a tube of the stuff at Boots, and the problem vanished within a week. It came back when I bought the US version after returning to the States. Fortunately Amazon has the useful version (from resellers in the UK and Spain), so I didn't have to bother my daughter who lives in the UK to send me some. Be sure the version you get mentions "Novamin" in the formula. The American version is just like old Crest, stannous fluoride toothpaste, the European is sodium fluoride toothpaste with an extra ingredient, brandnamed "Novamin", something called a "bioglass" that binds to exposed dentin and essentially makes new enamel (not chemical identical to tooth-enamel, but it does the same job).
