The effects of climate change on plant biodiversity can be predicted by using various models, for example bioclimatic models. [5][6] Habitats may change due to climate change. This can cause non-native plants and pests to impact native vegetation diversity. [7] Therefore, the native vegetation may become more vulnerable to damage.
Climate change is already now altering biomes, adversely affecting terrestrial and marine ecosystems. [2][3] Climate change represents long-term changes in temperature and average weather patterns. [4][5] This leads to a substantial increase in both the frequency and the intensity of extreme weather events. [6]
The report concluded that global warming of 2 °C (3.6 °F) over the preindustrial levels would threaten an estimated 5% of all the Earth's species with extinction even in the absence of the other four factors, while if the warming reached 4.3 °C (7.7 °F), 16% of the Earth's species would be threatened with extinction.
The diversity of species and genes in ecological communities affects the functioning of these communities. These ecological effects of biodiversity in turn are affected by both climate change through enhanced greenhouse gases, aerosols and loss of land cover [citation needed], and biological diversity, causing a rapid loss of biodiversity and extinctions of species and local populations.
Deforestation is a primary contributor to climate change, [1][2] and climate change affects the health of forests. [3] Land use change, especially in the form of deforestation, is the second largest source of carbon dioxide emissions from human activities, after the burning of fossil fuels. [4][5] Greenhouse gases are emitted from deforestation ...
They also concluded that climate change would result in the extinction of many species and a reduction in the diversity of different types of ecosystems (p. 792). Terrestrial ecosystems and biodiversity : With a warming of 4-5 °C, relative to 2010 levels, it is likely that global terrestrial vegetation would become a net source of carbon ...
Biodiversity is commonly measured in terms of taxonomic richness of a geographic area over a time interval. In order to calculate biodiversity, species evenness, species richness, and species diversity are to be obtained first. Species evenness[181] is the relative number of individuals of each species in a given area.
Biodiversity loss happens when plant or animal species disappear completely from Earth (extinction) or when there is a decrease or disappearance of species in a specific area. Biodiversity loss means that there is a reduction in biological diversity in a given area. The decrease can be temporary or permanent.
