John Cook's excellent resource skepticalscience has taken an innovative twist: he's repackaged his quick comebacks to tired talking points from global warming skeptics or deniers into an app for the iPhone and iPod Touch. (This may be a 'tipping point' for me to take the plunge on an iPod Touch that I've been 'i'-ing for a while.)
The great thing about this is that John's neatly organized material actually lends itself to just such a platform. Now, I am saying this without having bought that iPod Touch yet - but I've been quite impressed with his website. John boils down the essential issues and backs up his responses with links citing original peer-reviewed research.
John's new iPhone app is getting plenty of buzz in the media and online. Today it was picked up in the latest post on RealClimate (now that's the big time.)
