Healthy ecosystems and rich biodiversity are crucial to life on our planet. Climate change is harming the habitats of various kinds, which must either accommodate or migrate to regions with more favorable conditions.
In general, many species have extended their reaches towards poles in latitude and higher in elevation. Populations of several species have diminished, and although in some states climate change is considered to have committed to the decline. At the species level, variations perceived that can be associated with environmental change include those surrounding phenology. Many birds and insects are revealing variations, such as earlier incipience of movement, egg-laying, and breeding. In terms of ecosystems, there has been some indication of changes in population. e.g. desert ecosystems have developed, and tree lines in range systems have replaced.
