Climate change messes up blooming timing because some plants need certain time periods of cold and being dormant before their "chilling requirements" are being met. Farmers are forced to specifically pick plants with 20% shorter chilling requirements than to local climate's native plants just to make sure it doesn't get warm too early, so they could have their harvest quota covered. It's really an issue as some fruit trees are really sensitive and the area where they can thrive is getting narrower and narrower every year (on the map).
