Obviously you don't grow fruit or vegetables. The changing climate is causing huge issues with the viability of agriculture. The crazy swings in temperatures when we transition from winter to spring is outpacing the ability of some crops to adjust. In the last 20 or so years I have noticed that several of my fruit trees (down in Florida) are flowering early due to the warm winters just to have a frost/freeze (the crazy swings in temperature) kill all the blossoms, hence no fruit that year. This is happening quicker than evolution can cope without huge die offs. It's not a good thing.
