From James Annan, climate scientist:
Do solar/heliospheric changes affect the earth's climate?
That was the title of the keynote talk at a workshop held here last week. To save you the trouble of reading any further, I should just say now that the answer provided was "no, at least not to any significant extent since the middle of last century".
I may play around later with Inhofe's updated (650 scientists!) list of deniers. But one of the new names on the list is Oliver "Iron Sun" Manuel, who I have previously written about here.
