In Spain, the country with more land under vines than any other, it is harvest time for wine growers.
Ten years ago, most wineries would start gathering in their grapes during September. However, climate change has caused the temperature to rise and now grape varieties are ripening up to a month earlier.
Climate change is now a threat to the industry in Spain and a challenge for wine makers worldwide.
But if temperatures in Spain keep rising - and they have gone up by 2C on average in the past 50 years - the wines could taste very different and some vintages will be ruined.
