A Reuters article today describes reports on rapid changes in habitats due to warming temps. The article discusses the pressure on species, from plants to insects to animals, that will require migration north to cooler temperatures and whether many species will not be able to make the curve and eventually become extinct.
At issue is an important fact to remember: current rates of extinction far exceed the normal extinction rates of past millions of years. The spike in extinction has occurred in the industrialization period of human history.
Anther key issue is to remember that each species is part of a community of species that are linked. Loss of one affects many others.
