Dr Martin Rodger holds a PhD in Operations Management although originally he was a Mechanical Engineer. Living in Poole Dorset UK, he has been educating people about global warming locally for almost two decades. As a member of local group 'Poole Agenda 21' he has written extensively on many aspects of climate change and Greenhouse Gases for their newsletter.
As those denying global warming have grown more vocal, so has Dr Rodger. In 2011, he dusted off many of the illustrations used in the PA21 Newsletter and now keeps them up-to-date on a website MARCLIMATEGRAPHS to plot the continuing progress of climate change. His posts at DeSmogBlog began in 2012 with a series examining an organisation he considers "a national disgrace" - the Global Warming Policy Foundation.
