RE: ‘The Sceptic Meets His match' (Nature vol 475 28 July 2011: 440-441), Jeff Tollefson.
In the recent issue of nature (vol 475 28 July 2011), Jeff Tollefson reported about a pamphlet of the Heartland Institute from 2007. Results from our 2003 survey among climate scientists were used for the statement “The survey clearly shows that the debate over why climate is changing is still underway, with nearly half of the climate scientists disagreeing with what is often claimed to be a ‘consensus view’”. Tollefson goes on to accurately state that “In the survey, nearly 56% of climate scientists agreed that human activity is causing climate change, 14% were unsure and 30% disagreed”. Tollefson also goes on to state that Bast [founder of the Heartland Institute] “dismisses the findings of a follow up survey by Bray and von Storch [this is our 2008 survey] which found that more than 85% of the responding scientists agreed that human activity is behind climate change.” - also an accurate interpretation of the survey data. Tollefson spoke to one of us (HvS), and we find his research done well.
