- haverkort et al. showed effects of increased CO2 and temperature on crop growth in different agro-ecological conditions. It is urged to take these findings as a point of departure (state of art) and start your research from there rather than from mid1990ies modelling. Jaggard, K.W., Qi, A., Ober, A.A., 2010.
