I am not going to allow myself not to perform well just because I don't feel well. I am bulletproof to the extent that a lot of things can be thrown at me, but it's about how much I am prepared to let them affect me
There is no significant man-made global warming at this time, there has been none in the past and there is no reason to fear any in the future. Efforts to prove the theory that carbon dioxide is a significant 'greenhouse' gas and pollutant causing significant warming or weather effects have failed. There has been no warming over 18 years.
