According to one study, nearly 1 out of 2 species is threatened with extinction in the most biodiverse regions of the world due to global warming, right now. In the future, however, global warming can lead to the extinction of up to 50% of the animal, plants, and aquatic species.
Up to 50% of the animal and plant species can extinct by 2080
Between 25% and 50% of the animal and plant species living in the richest regions of the world in terms of biodiversity, could thus disappear by 2080.
According to a recent report, global warming will be the main cause of this extinction.
This unprecedented study was conducted in 35 priority ecoregions defined by the WWF, among which are the Alps, the Camargue, the Mekong Delta, and the Amazon.
A gloomy future for animal and plants species
Three scenarios were studied by researchers at the Tyndall Center for Climate Change and WWF.
The first corresponds to a temperature increase of 2 degrees Celsius and the second scenario imagined a temperature rise of 3.2 degrees Celsius, both corresponding to current climate change forecasts for 2025- 2030.
On the other hand, the last scenario imagined a temperature rise of 4.5 degrees C, which could happen if humanity will not implement concrete solutions to fight against global warming, according to the WWF.
As expected, this last scenario is the most catastrophic one since it would lead to the disappearance of at least 35% of all the animal species.
Aquatic and plants species are equally threatened by global warming
In the Amazon, an area extremely sensitive to climate change, the increase in temperatures would threaten more than a third of the species. And this is also the case for the Mediterranean which would also face the extinction of more than 35% of its species, including aquatic species.
“Beyond the obvious economic and social repercussions, we expose ourselves to profound changes impacting ecosystems providing vital services to hundreds of millions of people,” says WWF.
The report says that global warming can lead to a chain effect. If temperatures rise, more than 50% of plants may disappear in some parts of the world and this would have a detrimental influence on a large number of animal species.
