How might critical thinking be applied to the issue of global climate change?

Climate change can be a polarizing, and emotional, topic for many people, but like anything else, you have to decide who to believe. Many scientists and people believe in climate change. Others vehemently deny that it's even happening. Both sides provide evidence to support their views, but it is up to you to use what you know to think through their arguments and come to your own decision. I guess that's where critical thinking comes in. Instead of blindly following one side because they seem the "smartest" or the "best" or the "loudest", you have to use your head to ask "why" and whether they make the most sense.
