The researchers found that by 2050, in a scenario with a moderate amount of future greenhouse emissions, 76 per cent of urban tree species will be living outside their preferred temperatures and 70 per cent will be living outside their preferred level of precipitation.Ĭities are likely going to want a lot more trees as the climate heats up, not less. The study authors note that cities might be doing things like watering some trees, or the species may be a little more flexible and able to survive, even if it’s not thriving.Īs the climate crisis gets worse, that flexibility may be tested even more. That doesn’t mean these trees are all about to die. Ĭurrently, 56 per cent of tree species are living in areas with non-ideal temperatures for that species - and 65 per cent of species were living in areas with non-ideal amounts of precipitation. Results were published on Monday in the journal Nature Climate Change. The team looked at what kinds of temperature and rainfall conditions each tree species prefers, and then compared that to the temperatures and rainfalls both now and in a climate-altered future.
Some, like trees from the rainforest, may prefer hot and wet conditions, while others, like trees from mountain regions, may prefer habitats that are cool and dry.
The researchers looked at more than 3,000 species of trees in 164 different cities, from the US to South Africa to China.ĭifferent tree species - having evolved in different corners of the world - are going to have different needs to stay healthy.
