If you find yourself in an argument with a climate-change skeptic, you can find the perfect riposte just a few taps away on your iPhone. Skeptical Science, a site that compiles peer-reviewed research about climate change, is now available as an iPhone and iPod app.
If the skeptic you encounter presents a specific argument, know that Skeptical Science offers evidence to rebut the ten most common claims, including “The climate has changed before,” “There's no consensus,” and “Models are unreliable.”
