Is Climate Change real, and caused by us?

It is tempting to write a whole page of text reiterating what is being said by genuine experts, but it’s actually easier just to link to intelligent, authoritative, and well-presented sources, like Simon Clark’s videos. In the first video, he explains how we know climate change is being caused by our industrial processes, and not, say, that it’s not happening, or that its coming from volcanoes or something similar. There are other great videos on the Simon Clark channel that cover other questions one might reasonably have.
