Large portions of the continent may become uninhabitable as a result of the rapid effects of climate change, which would have disastrous effects on human health, food security, and poverty. [41] [42] [43] Regional effects on rainfall in the tropics are expected to be much more spatially variable. The direction of change at any one location is ...
Therefore, when environmental conditions change, this can result in changes to biodiversity. [4] 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.
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
The land use change and sea use change was considered the most important stressor, followed by direct exploitation of organisms (i.e. overfishing). Climate change ranked third, followed by pollution and invasive species. The report concluded that global warming of 2 °C (3.6 °F) over the preindustrial levels would threaten an estimated 5% of ...
The loss of biodiversity may not directly affect humans, but the indirect effects of losing many species as well as the diversity of ecosystems in general are enormous. When biodiversity is lost, the environment loses many species that perform valuable and unique roles in the ecosystem.
Climate change is likely to favour some invasive species and harm others, [161] but few authors have identified specific consequences of climate change for invasive species. [162] Invasive species and other disturbances have become more common in forests in the last several decades. These tend to be directly or indirectly connected to climate ...
[11] [12] Furthermore, a loss in biodiversity makes it harder for ecosystems to adapt to climate change. [12] With over half the global GDP being dependent on nature and the livelihoods of over 1 billion people worldwide connected to forests, the consequences of biodiversity loss are extensive.
The main sources of Africa's 3.6% share of the world's Carbon dioxide emissions are gas flaring in the Niger Delta and coal-fired power plants in South Africa. [23] But, the continent's forests are rapidly disappearing because of desertification and deforestation, which has negative consequences for both Africa and the climate at large. [24]
