Dana Nuccitelli is a key communicator in the climate change conversation. He is co-writer with John Abraham at the Climate Consensus - the 97% blog at the Guardian, and has contributed hundreds of entries to John Cook’s famous site SkepticalScience.com. He has measurably helped people to understand climate change science and the nuances of the false debate based over climate manufactured by science deniers.
And, he’s written a book!
