Watts Up With That? (WUWT) is a blog promoting climate change denial that was created by Anthony Watts in 2006. The blog predominantly discusses climate issues with a focus on anthropogenic climate change, generally accommodating beliefs that are in opposition to the scientific consensus on climate change. Contributors include Christopher Monckton and Fred Singer as guest authors. In November 2009, the blog was one of the first websites to publish emails and documents from the Climatic Research Unit controversy, and a driving force behind its coverage.
