I am clever enough to admit that I don't know the answer to does global warming exist. A physicist friend of mine told me man-made global warming heats the earth about as much as taking a slash heats up a pool. Regardless fossil fuels are a limited resource that should be used less and more efficiently, that's just common sense!
As for evolution I do think this should be the only explanation of life taught in science. There are countless studies in fossil records showing gradual change of species and it's been proven real time using moths. Creationism should be confined to religious studies. If you chose to believe it that's absolutly fine but you're going to need something more than a 2000 year old book as evidence before it will be taught in uni.
