Read our privacy policy All species on Earth appear to thrive at an “optimal” 20 degrees Celsius, according to a new study, which suggests land species may struggle more to adapt to changing climate. This means temperatures warmer than 20 degrees could result in several crucial changes among organisms, such as a reduction in tolerance to low oxygen levels among marine species, researchers explain. Polar bears face starvation crisis as 'climate change forces extended land stays' In a warming world, creatures unable to move to comfortable temperatures may struggle more to adapt. While marine species can adapt by altering their geographical distribution, land species may not be able to shift so easily “due to landscapes modified by cities, farming, and other human infrastructures,” scientists write in The Conversation.
