I must reply to the nasty characterization of myself by Ron Scholl (“Climate change: Information not exactly credible,” letter, March 28). He makes a number of false statements, including to question my credibility as a scientist. For his information, I hold bachelor’s degrees in biology and forest biology, a doctorate in ecology, an honorary doctorate of science from North Carolina State University and in 2009 received the National Award for Nuclear Science and History from the Einstein Society. In 1989 I founded the British Columbia Carbon Project and ever since have remained abreast of the climate change discussion on a daily basis.
In my testimony before the U.S. Senate I simply stated, “There is no scientific proof that humans are the main cause of the minor warming that has occurred over past 150 years.” This is why the Intergovernmental Panel on Climate Change uses the word “likely” when it states that humans are the main cause. This is a judgment (opinion), not a proof. If there was an actual scientific proof, they would write it down on a piece of paper and show it to us.
Scholl also claims that I am not a co-founder of Greenpeace. If he would take the time to Google “Who are the founders of Greenpeace,” he would find my name clearly displayed. Just because Greenpeace has tried to write me out of their history doesn’t actually change historical fact. I was in the leadership of Greenpeace for 15 years, from the first campaign against U.S. H-bomb testing in 1971 until 1986, when I left due to disagreements on points of science and policy. Today Greenpeace campaigns are mainly based on sensation, misinformation and fear. I prefer to base my environmental policies on science and logic.
