A new study published in the journal Nature Climate Change reveals that the existence of all tree species in Delhi is under threat due to climate change. The study has highlighted that the future of nearly half of the world's city-dwelling tree species is at risk due to rising temperatures and changes in rainfall.
Researchers studied the threat of climate change to 3,129 species of trees and shrubs in 164 cities in 78 countries. The findings show that 56 per cent of the tree species in cities, or more than 1,000 species, are already at risk of rising temperatures and changes in rainfall. The conditions have already gone beyond the natural tolerance limits of these trees due to rising temperatures and water scarcity.
On the other hand, if the havoc of rising temperatures and climate change continues like this, then scientists estimate that in the next 28 years, about 76 percent, or 2,387 species of trees, will be at risk. Scientists estimate that its highest risk is highest in low-latitude cities such as Delhi and Singapore. All urban tree species are vulnerable to climate change. Globally threatened tree species include acacia, neem, peepal, oak, maple, cherry, plum, poplar, wattle, eucalyptus, and chestnut. The researchers pointed out the importance of saving these trees not only to sustain life in these species of trees but also in cities. Also, as many trees as possible should be planted in cities, they added.
