I'm still trying to understand. Have patience with me?

I'm learning a little more with each question I ask. I keep asking them because the info I'm finding on the internet is mostly over my puny head, except for a couple of websites recommended by people here. From reading answers here, it seems like many of you are scientists. So my lay-man follow-on question is: If global warming IS just a part of the natural cycle of things in Earth's climatic history and not man-made, isn't it still a good thing to reduce carbon emissions? I mean like wouldn't it be easier to breathe in traffic congested areas?
