"Climate change" was originally called "global cooling". But the Earth stopped cooling down, so they called it "global warming".
But then it kind of stayed the same, so they rebranded it "Climate Change".
My opinion: "climate change" is an extremely young field of science, filled with biased theories that are based on huge extrapolations and logical jumps. The scientists that make most claims have a track record of continuously being wrong, and unnecessarily scaring people.
Until the science becomes more precise, and the predictions actually happen, then I'll choose to ignore "climate change" and the whole "end of the world" talk all together.
To answer your question directly, no, I don't think we should do anything about climate change. The Earth warming up is not necessarily bad. It'd be a lot worse if it was headed the opposite direction and we were all headed for an Ice Age.
