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 ...
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.
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.
Climate change and the associated changing weather patterns occurring worldwide have a direct effect on biology, population ecology, and the population of eruptive insects, such as the mountain pine beetle. This is because temperature is a factor which determines insect development and population success. [87]
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 ...
Red list categories of the IUCN Demonstrator against biodiversity loss, at Extinction Rebellion (2018).. The current rate of global biodiversity loss is estimated to be 100 to 1000 times higher than the (naturally occurring) background extinction rate, faster than at any other time in human history, [25] [26] and is expected to grow in the upcoming years.
Summary of major environmental-change categories that cause biodiversity loss. The data is expressed as a percentage of human-driven change (in red) relative to baseline (blue), as of 2021. Red indicates the percentage of the category that is damaged, lost, or otherwise affected, whereas blue indicates the percentage that is intact, remaining ...
Ecosystem-based Adaptation (EbA) describes a variety of approaches for adapting to climate change, all of which involve the management of ecosystems to reduce the vulnerability of human communities to the impacts of climate change such as storm and flood damage to physical assets, coastal erosion, salinisation of freshwater resources, and loss of agricultural productivity.
