Dear old birdbrain, that question has been put and answered many times before on this thread and in many other.places. And you still don't get it.

if it's your belief that this objective fact isn't true, then your belief could more accurately described as a personal deluson.

here's what no less of a scientific authority than NASA say on an internet page marked science.nasa.gov.

"the vast majority of actively publishing climate scientists – 97 percent – agree that humans are causing global warming and climate change."

birdie, you of course don't have to accept that but out of respect perhaps you could choose not to burden others with your bizarre personal delusion.
