Climate change can lead to sudden biodiversity loss worldwide. This conclusion was made by climatologists from University College London, a study of which was published in the journal Nature.
Researchers compiled a model that included data on climate change from 1850 to 2005. Then, the results were compared with the effect of climate change on populations of 30,652 species of birds, mammals, reptiles, amphibians, fish, and other animals and plants.
Based on these data, the researchers compiled a correlation between climate changes and their impact on animal populations and used it to predict changes until 2100.
Researchers have found that in most ecological communities around the world, a significant proportion of organisms will fall outside their temperature comfort zone over the next decade.
The paper says that if global temperatures rise by 4°C by 2100 (this will happen in the middle scenario with high emissions), at least 15% of animal and plant communities around the world will be suddenly affected by climate change. Such events can cause irreversible damage to the functioning of ecosystems, the author of the study concludes.
