How climate change impacts the diversity of living things

Climate change impacts biodiversity because a global rise in temperature will change the habitats that life uses and cause many species to become extinct. This is going to be very drastic if global warming continues at this rate. For example, "new analyses suggest that 15–37% of a sample of 1,103 land plants and animals would eventually become extinct as a result of climate changes expected by 2050." (Nature)

Living things are used to a certain type of climate and usually are able to adapt to slow changes in climate but many species will not be able to adapt quickly enough to the quick rise in temperatures with Global Warming. For example, a certain climate might be perfectly suitable for a plant species but if that climate were to quickly change, the plant species might not be able to adapt and survive. If plant species were to die out, the animals of that ecosystem would also be affected. Also, physical changes in the environment might make species die out. An example of this is the loss of ice in places where polar bears live. This loss of space is affecting the polar bears because they are having less and less room to live.

Climate change impacts the diversity of living things because, if the species cannot adapt, they will become extinct.
