Reacción a "Reactions: Review details impacts of climate change on global wine production"

I think the paper is an excellent review of the influence of climate change on the future development of viticulture. Its impact will be greater in regions that already have a warm and dry climate, such as those located in the southern half of Spain. 

There is still a lot of work to be done. There are some 10,000 varieties of vines in the world for all uses: wine, spirits, table, sultanas, juices, etc. Worldwide, 16 of them, 50% of the world's cultivated area of wine grapes, and in Spain three varieties (Tempranillo, Airén and Bobal) account for 50% of the area planted with wine grapes. 

We must look for other varieties that are better adapted to the new climatic conditions and, if we do not find them among those that already exist, develop genetic improvement programmes, such as the one initiated at IMIDA at the end of the last century, and try to obtain new varieties that are better adapted to the new climatic adversities. In this sense, four new varieties have already been registered, three red (Myrtia, Gebas and Calnegre) and one white (Calblanque), from crosses of Monastrell with Cabernet Sauvignon and Monastrell with Syrah.
