On Thursday March 26th I chaired the first of the monthly science public debates at the new Science Gallery at Trinity College Dublin. The topic for debate was ‘Is the Biofuel Dream Dead?”. On the panel was Professor Keith Smith of the Institute of Atmospheric and Environmental Science at the University of Edinburgh. Professor Smith co-authored a recent controversial paper with Nobel winning chemist Paul Cruzen stating that the N2O release from agro-biofuel production negates global warming reduction by replacing fossil fuels. You can find a description of the study here and details of the debate on the science gallery website.
