"a change that is ascribed directly or indirectly to human activity that modifies the chemical makeup of the world's atmosphere and that is in addition to natural climatic variability seen over similar time periods," as defined by the United Nations Framework Convention on Climate Change (UNFCCC). Temperature rise, precipitation shifts, and more frequent occurrences of heat waves, cold snaps, frosty days, droughts, floods, and other severe weather events are all predicted as a result of climate change. Climate change poses a significant threat to several aspects of plant life, including vegetative development, blooming, fruiting, and the quality of fruit. Crop production is predicted to decrease as a result of two primary aspects of climate change: more variable rainfall patterns and unexpected high temperature spells.
