Climate change around the world is not predicted to be uniform. Most places will get warmer, some will get more rain and others will get less. For areas of Arizona, warmer temperatures are expected to provide a boost in plant growth caused by a longer growing season and more carbon dioxide in the air. However, a new study from Northern Arizona University suggests the contrary. Warming temperatures will cause an initial boost in plant growth, but will quickly diminish over the years. This may lead to significant deterioration in future plant growth.
