It's a lot easier to worry about sulfur dioxide and NOx producing rain compared to worrying about global carbon emissions. Climate Change seems best dealt with at a local level, with the cause of the problem being pollution.

This site looks very interesting but I'm not quite sure what I'm looking at. What is that map for and how does it filter sources, since it seems like it doesn't include all airports.

There’s a lot of information there. They literally answer the question “What am I looking at?” in the first popup you get (How to use, top left corner).
