Areas of Greece are among those at risk.
Researchers warned that celebrated wine regions in California, Spain, Italy, France and Greece could disappear if the planet exceeds the 2°C threshold.
They reached this conclusion after reviewing more than 200 studies into the impacts of climate change upon grape production.
‘For temperature increases beyond 2°C, 70% of existing winemaking regions might face substantial risks of suitability loss,’ wrote the researchers in their report, which was published in the Nature Reviews Earth & Environment journal on Tuesday.
‘Specifically, 29% might experience too extreme climate conditions, preventing premium wine production, while the future of the remaining 41% will hinge on the feasibility of effective adaptation measures.’
Average global temperatures were 1.52°C above the pre-Industrial Revolution era in the 12 months to January 2024, according to EU data.
This led to searing heatwaves, extraordinary drought and deadly storms. It also had a major impact upon wine production, as yields fell to their lowest level since 1961.
The International Organisation of Vine and Wine (OIV) attributed the low levels of production to bad weather, including frost, heavy rainfall and drought.
In 2015, a total of 196 countries signed up to the 2015 Paris Agreement in a bid to tackle the negative impacts of climate change. Their shared goal is to ensure that global temperatures do not increase by more than 2°C above pre-industrial levels.
However, global greenhouse gas emissions rose by 1.1% year-on-year in 2023, according to the International Energy Agency. Meanwhile, a 2023 report from
