It’s holiday time here in the US. If you find yourself at a gathering of family and/or friends, and the topic of climate change comes up, and you need to rebut any kind of denier nonsense, here is a link to Skeptical Science’s counter arguments for most of the denier “challenges” to the science about climate change: http://www.skepticalscience.com/argument.php

This website is loaded with up-to-date information about many aspects of climate science and it often has a “beginner’s” answer and a more technical explanation, as well. Just use the link above, and go to their Home page to peruse the site.
