According to research, the optimal temperature for the development of all living species on Earth has been determined to be 20 degrees Celsius. Temperatures above this level pose a threat to the growth of living organisms.
Studies have confirmed that both animals, plants, and microbes living in air and water reproduce best at around 20 degrees. Scientists state that this temperature appears to be “crucial” for biodiversity: “We find evidence that temperatures above 20 degrees are increasingly suboptimal for all areas of life, including animals and plants. Due to the molecular properties of water in cells, a temperature of 20 degrees is essential for the efficiency of biological processes.”
Fossils are also at risk of disappearing. According to researchers, temperatures above 20 degrees may lead to changes in marine species, such as reduced tolerance to low oxygen levels. In a warming world, organisms that cannot reach comfortable temperatures may struggle more to adapt. Scientists expect that if temperatures remain above this threshold for a long period, similar extinction patterns may be observed in fossils. These findings add to the growing evidence that biodiversity, already declining above 20 degrees, will worsen further with global warming. Researchers warn that this will lead to the “simplification” of ecosystems with fewer life forms in many areas. There will be increased competition among existing species, potentially further limiting their habitats.
