Not only is there is no evidence that he is an environmentalist
Dr Ian Langford is a Senior Research Associate in CSERGE, specialising in statistical methods applied to environmental and health-related issues. He has a wide range of research interests applying statistics to a number of problems, particularly climate change and health, economic valuation of the environment, and risk perception, particularly of environmental risks to health. He also works on statistical theory and methodology, and is developing analytical tools for spatial analysis in conjunction with Prof. Harvey Goldstein, of the Institute of Education in London, with occasional workshops being held on multilevel modelling. Information on this work and the workshops can be found on the Multilevel Models web site: multilevel modelling
unless you believe that there is no room for serious study of the environment without being a radical greenie, to want someone dead because of their political views is disgusting. Imagine if GWB was assasinated and someone wrote "the world is better off without him", you would be spitting chips in your urge to maul him.
