Climate: Average & VariabilityClimate: Average & VariabilityMain recommendation

» Crop development is affected not only by the mean atmospheric conditions (average climate), but also by the frequency of extreme events such as frost, heat waves, floods, and droughts; or even recurrent conditions unfavorable to crop growth.

» Photosynthesis is not linear related with temperature

» GHG may change not only the average, but also the frequency
