Dr Paul JohnstonIt's official. Our scientist Paul Johnston, or PJ as he's affectionately called around here, is more important than Buddha, the Dalai Lama, and more weirdly, Jamie Oliver and Father Christmas. Today the Guardian names the Environment Agency's Top 100 green campaigners of all time, and PJ has come in at a respectable number 40. Nice one PJ!

The citation says:

"Chief Greenpeace scientist who set up the Greenpeace Research Laboratories at London's Queen Mary College in 1987 and continued as principal scientist when they relocated to Exeter in 1992. He has been providing scientific advice and expertise to Greenpeace offices around the world for nearly 20 years."
