This is exactly the point of people not understanding how science work :)
I dont know how its even possible for you to be wrong about every statement you make, but let me school you boy.
Science is based on evidence, the more you study something the better results you get. Yes ideas about climate change has changed in the last 120 years, but didn't I just say that the real difference has been in the last 30-40 years? Changes are more drastic, more studies have been made. More evidence have been collected. Sigma value of climate change studies are becoming higher and higher.
Secondly science is never final, yes it is possible that the science is wrong about the climate change, though nobody can say how it could be wrong, but it can be, it is just highly unlikely. Just like you can win in a lottery, but probably wont. So it is best to assume you wont win in a lottery and that climate change is real.
Then your next mistake. I find it funny, just like a peeing monkey, when people keep coming up the same stupidities over and over and over again. Its like you've never opened a science book (maybe any book?). Theory means fact. Just let it sink in. Scientific theory like evolution theory means fact. Thats what it means. There is no such thing as "missing link", that is no how evolution works, but you can read more about these great mistakes from another religious science books.
And I wouldn't even even care to go to gravity, as you clearly have no basic understand of physics, but hey what the hell. Gravity has basically have two theories, Newtons theory of gravity and Einsteins general relativity. Both are very true still to this day. But yes through Einsteins general relativity we could understand that gravity is not a force, but a shape.
Yea. Science have given you everything in your life, your house, your computer, your phones, your clothes, your food, your internet. Now it is giving you the truth about climate change and you think there is something wrong about science. Keep up the good work.
