- Abstract
Climate change is an incontestable phenomenon, one of the major threats to the environment and implicitly over humans. According to the European Environment Agency, climate changes mean global warming, increased sea and ocean temperatures, average global sea and ocean elevation, water acidification, shrinking glaciers due to the extensive melting of glaciers, desertification of green areas, and intensification of extreme meteorological phenomena (floods, long and prolonged drought, storms, etc.). Regarding vine culture, it is known that the main restrictive factors are climate factors, which have a decisive importance on this plant. Temperature and humidity, mainly determine the optimal run of the annual biological cycle of the vine, so of the phenophases. The main forecasts show that temperature variation will increase considerably in most wine regions in Europe. Thus, the increase in temperature will have serious implications for viticulture, especially as regards the plant-water relationship. Changes in the phenology of varieties are already recorded, with the forced triggering of the parga stage and the ripening of the grapes. Due to the fact that the grains of the grapes do not reach the varietal sizes, their must efficiency decreases. Some specialists also show that elevated temperatures and the lack of rainfall during the summer, to ripen grapes, prevent the attack of gray rot and favor the accumulation of sugars.
