Southern California has seen a resurgence of winegrowing regions in the past few decades,however the future of winegrape climatic suitability in the area has not been exhaustively explored.This study evaluated the future climate suitability for the cultivation of winegrape and potential global warming impacts on southern California's winegrowing regions through a series of high-resolution surface air temperature and precipitation projections obtained with the WRF-SSIB regional climate model.Results reveal that by mid-21st-century the surface air temperature will increase by approximately 1.2℃,while average precipitation will decrease by as much as 11%in the southern winegrowing areas under the Intergovernmental Panel on Climate Change high greenhouse-gas emissions scenario.Evaluation of bioclimatic suitability indices indicate increases in heat accumulation for all major winegrowing areas;including an increase of about 10% in growing-degree day,while morning low temperatures in September may experience increases of approximately 11% in the future,thus impacting negatively the ripening stage of grapevines and leading to changes in wine composition and quality.Additionally,the extent of areas classified under the cool to warm climate suitability categories could decrease by nearly 42% in the study area by 2050.Conditions in southern California are already warm and dry for viticulture and continuing heat accumulation increase,along with rainfall reduction,could potentially place additional stress to winegrape crop in the area,including advanced phenological timing and moisture deficit stress that could lead to decreases in yield.The projected decline in viticulture suitability highlights the need for adaptive capacity within this sector to mitigate the impacts of global warming.Possible mitigating strategies include planting hotter climate grape varieties,moving vineyards to regions that are more suitable in the future,and adopting dry-farming techniques.

Aims and Methods We propose a standard protocol at the landscape to continental scale for examining to what extent the range of ecological conditions found in temperate latitudes explains the variations in climber species richness and traits.The protocol was tested in forests of the two Americas.The data set included 151 climber species.We selected four categorical traits and grouped these species into six clusters with regard to these traits.Floristic records of American forests were first gathered into alliances,second combined with Bioclimatic indices(rainfall,temperature,continentality).We obtained a total of 59 vegetational units in which we calculated values of climber species richness and proportion of clusters.Vegetational units were ultimately gathered into five forest formations(characterized by leaf longevity).Wetlands and uplands were considered separately.Important Findings Our results emphasize clear trends in large-scale patterns of climber distribution,independently of taxonomy.Climber species richness(in particular woody climbers)peaks in moist and warm upland forests with oceanic climates,and where conifers are rare.In flooded areas,climber richness is also very high and peaks in seasonally flooded large floodplains.In ecological conditions of frost,dryness or lack of nutrients,climber species richness,abundance and trait diversity decline,resulting in the dominance of small,twining and deciduous life traits.
