Pretty much what Tony said - bigotry isn't about holding the view that Climate Change is a very real problem, it's refusing to listen to anyone else as you provide the solution. Climate change sceptics are often bigots too.

Climate change is a complicated issue, tied up with international politics, poverty, trade, transport, resources, technology and a whole host of other things. To make any feasible change will require significant numbers of people to make complex decisions with lots of unintended consequences. The Climate bigot doesn't want to hear about the complexities of economics or business they want GREEN THINGS! now! And fewer of X things!

What do we want? CHANGE! How should it be implemented. WE ARENT SURE! But we know you're wrong for driving a car and now we're laying in the road so you can't get where you want! Hah! Climate saved. Those people. If you're rationally raising concerns about climate change - that's great, chances are you're not a climate bigot.
