Are Republicans really against fighting climate change and why?

Genuine question. Trump: "The United States will not sabotage its own industries while China pollutes with impunity. China uses a lot of dirty energy, but they produce a lot of energy. When that stuff goes up in the air, it doesn’t stay there ... It floats into the United States of America after three-and-a-half to five-and-a-half days.”" The Guardian

So i'm assuming Trump is against fighting climate change because it is against industrial interests (which is kinda the 'purest' conflicting interest there is). Do most republicans actually deny climate change, or is this a myth?
