....because you're an idiot.
The principles of AGW like Special Relativity is the science and Einstein wasn't the idiot.
He was accused of doing so by a number of people. Some of whom just denied the science and wore their imbecility as a badge of honor similar to yourself.
All science is based on continuing dialogue toward truth.
The scifience of global warming is based on shutting down the opposition's voice.
I'm not surprise that an idiot like you doesn't know the difference.
So the only way you can get over the continuing dialogue is to call something that isn't scifience , scifience. Yet there were far more compelling arguments against Einstein, by far more eminent scientists, than have denied the science which supports the fundamentals behind AGW.
Bottom line is blind denial is all that nitwits like you will ever manage.
