Up to 70 per cent of the world's wine regions could become unsuitable for wine growing if global warming exceeds two degrees Celsius. This is the conclusion of a report published in the renowned scientific journal Nature . In it, researchers analysed more than 200 studies on the consequences of climate change for viticulture.
According to the article, climate conditions could become so extreme in up to 29 per cent of existing wine-growing regions that the production of premium wines would become impossible. In 41 per cent of the regions, viticulture depends on effective adaptations. The traditional wine regions in the coastal and lowland areas of France, Spain, Italy, Greece and southern California are particularly affected by heat and drought. Up to 90 per cent of vineyards could disappear there.
On the other hand, a quarter of the current wine-growing regions could benefit from a temperature increase limited to 2°C. These include above all Great Britain, northern France, Washington State, Oregon and Tasmania. Another quarter are likely to maintain their current suitability for viticulture if appropriate practices are applied.
According to a report by the UN Environment Programme, global warming could reach 2.9°C by the end of the century if more is not done to prevent it. In 2023, global greenhouse gas emissions increased by 1.1 per cent compared to 2022, according to the International Energy Agency. EU data shows that global average temperatures in 2023 were 1.52°C higher than before the industrial revolution.
