Global warming which is as a result of human activities such as burning of fossil fuels and deforestation is a major threat to species diversity. This study is based on species in the climate change hotspots, using the SSDM, phenology, species traits, responses of ectotherms, and vegetation activity. We evaluate shifts in the distribution and numbers of species and their probabilities of dying out. An average Global warming of 1.1°C since the end of the nineteenth century has altered precipitation, deteriorated habitats, and increased the rate of species’ disappearance. If emissions are not reduced, 20-30% of species like the American Pika and many amphibians could be wiped out by end of the century. Phenological activities are taking place 2.5 days earlier per decade, which affects the balance of ecosystems. This study also stresses the importance of flexibility in conservation approaches like connecting the fragmented habitats, rehabilitating the disturbed ones, and the protection of ecological connectivity to reduce the impacts of climate change on species.
