Study: ‘Grapevine yield in [Portugal] is expected to undergo upward trend until end of this century, which might be further enhanced by projected upward trends in CO2 concentration’
International Journal of Biometeorology: 'Elevated CO2 concentration increased net photosynthetic rate, intrinsic water use efficiency & leaf thickness—the grapevines loved the higher levels of CO2! In 2004, the elevated CO2 increased yield by 50%, in 2005 by 27%, & in 2006 by 50%. -- 'The yield per vine showed a clear tendency to increase in elevated [CO2] in the 3 growing seasons' -- 'The models are indeed predicting changes that should benefit vines'
