Prof Jones has looked at measures to mitigate the effects of heat in places such as Hong Kong, Singapore and Miami. <\/p>\n
In Singapore, where temperatures in the city centre can be a 7C (45F) hotter than outside it, authorities are incorporating open spaces around buildings and lighter colours on walls and roofs, as well as increasing the amount of greenery in the city. <\/p>\n
Nearly half of Singapore is now green space and more than 500,000 trees have been planted since 2020 – with a target of one million by 2030.<\/p>\n
Varying building heights and even making the corners of buildings curved are all effective ways to reduce temperatures without the need for air conditioning.<\/p>\n
But as trees are inexpensive and take time to reach full maturity, Prof Jones said UK cities should start planting as many as possible now.<\/p>\n
The Welsh government said: “Trees on streets and in parks play a vital role in helping us adapt to the effects of a changing climate and in supporting wildlife in urban areas.<\/p>\n
