Parks and gardens hold key to cooling overheated cities

Nature in urban settings can have huge impact on temperature and human behaviour, study showsParks, trees, green roofs and gardens are what scientists call nature-based solutions to cooling overheated cities. Then there are the technical solutions, solar panels, heat pumps and other ways of cutting fossil fuel use. But even all these combined are not enough to reach the goal of net zero carbon emissions.This is partly because as climate change makes our cities hotter during the summer months, people tend to change their behaviour. For example, they may stop cycling to work and opt to sit in an air-conditioned car, making a bad situation worse. Continue reading...
