Why should we even look for factors from everywhere else? The finger points at us, folks.

I certainly agree, Grace, but I keep running into people (on the web, mainly) who have bizarre conspiracy theories about what they call ”the religion of global warming”. There are a lot of people who simply refuse to face facts, but they do cling to theories like blaming modern global warming on cosmic ray activity. Having a few scientific studies done independently, and the latest even by the US Naval Research Academy, removes much of the semblance of logic from these skeptics’ arguments. Whether the new results will change their minds is another question, because it seems to be a political decision the skeptics have made: they will not believe in global warming caused by man, because, for example, they don’t like Al Gore. I guess they are jealous. Best wishes!
