Marcel CrokMarcel Crok studied physical chemistry in Amsterdam and Leiden after which he became a professional science writer. In 2005 he wrote a lengthy and critical article about the notorious hockey stick graph. That episode was so intriguing that Crok decidd to work full time on climate change. He published a book in Dutch (The State of the Climate, 2010) and in 2013 was involved in the platform Climate Dialogue, a government funded initiative where climate scientists with different views exchanged ideas.
