Global warming is happening, but is it really something we can prevent?

by: MarkWhy don’t either side of the argument consider cosmic forces as the reason why the earth is heating up? For instance the earth’s orbit is elliptical and could be expanding or contracting causing periods of extended warmth and/or extended cold (ie Ice Age). If this is the case, we might not be able to prevent it and so cutting back co2 emissions might not be the answer and we might just have to deal with and adapt to a warmer planet.
