The shade provided by trees in your city may decrease with global warming

The best cities are defined by cultural diversity, a great arts and music scene, a solid restaurant selection, and access to some semblance of nature. For many metropolises, that translates to lush, landscaped parks, designated areas where humans can get a much-needed dose of greenery and take a deep breath. Unfortunately, it seems that many of the trees that adorn our world’s parks were not built to withstand the rising temperatures that are expected to accompany climate change.

According to a recent study published in the journal Natural climate change, between 56% and 65% of tree and shrub species in more than 150 countries around the world “exceed the temperature and precipitation conditions encountered in their geographic range”. Basically, just like us, they weren’t built for these extreme weather conditions.

In addition to the respite that trees provide us, they also refresh us and paving of the streets of our city, which, in the midst of record heat waves, is a welcome effect. To coincide with a warmer, stranger future, city planners may need to get as creative as we do in our home gardens, opting for drought-tolerant native plants and trees that can grow better. resist bad weather.
