Physicist John Cook of SkepticalScience has developed an iPhone app that provides answers to common questions about climate change.

I downloaded the app this morning, and after a short test-run, it seems fairly comprehensive and easy to use. The questions are divided into the categories “It’s not happening”, “It’s not us”, and “It’s not bad,” each of which features complaints ranging from the classics (“Glaciers are growing!”) to the latest issues with the IPCC (“They were wrong about the Amazon rainforest!”). The answer provided to each of these assertions includes a short talking point, followed by a longer, more detailed, fully cited (with links!) explanation of the science.

The Guardian has a more extensive review, but this could be a good tool for audiences who just want to know what to say when confronted with questions about the science. Let us know what you think of it.
