> Scientists arguing that global warming is primarily caused by natural processes

I count eight people who seem to have worked in (broadly) related fields:

    Timothy Ball, historical climatologist, and retired professor of geography at the University of Winnipeg
    William Kininmonth, meteorologist, former Australian delegate to World Meteorological Organization Commission for Climatology
    Anthony Lupo, professor of atmospheric science at the University of Missouri
    Tim Patterson, paleoclimatologist and professor of geology at Carleton University in Canada.
    Murry Salby, atmospheric scientist, former professor at Macquarie University and University of Colorado
    Nir Shaviv, professor of physics focusing on astrophysics and climate science at the Hebrew University of Jerusalem
    Roy Spencer, meteorologist; principal research scientist, University of Alabama in Huntsville
    George H. Taylor, retired director of the Oregon Climate Service at Oregon State University

You could probably raid a single decent university and find more people working on understanding AGW better.

This is the equivalent of saying "Zoologist X Somebody in University of North Carolina said there's no link between smoking and lung cancer!", and keeping smoking while having a lung cancer while ignoring mountains of research, except that it's not your own lung this time.
