Quotes about Haigh

 * She appears regularly on TV, radio and in print media, and as a result, gets a lot of emails – many from people who do not believe that humans are causing climate change. She tries to reply to them all unless they are directly offensive, but admits she has about a “two percent success rate” in positive responses to her explaining the science.
