Climate change and wine
Global warming could drastically alter the world wine map. Temperatures are expected to rise from 3° to 5°C by 2050, accompanied by a decrease in summertime precipitation, much more frequent heat waves (over 35°C) that are fatal to grapevines, increased soil erosion and irrigation problems. This investigative documentary surveys the research carried out and the decisions made by both vineyard owners and scientists to tackle the question of global warming.
