It is presently challenging to efficiently cool enclosed spaces such as stationary automobiles that trap heat via the greenhouse effect. In a new report in Science Advances, Se-Yeon Heo and a team of scientists in materials ...
Scientists have devised a simple new model that explains how the undesirable effects of urban heat islands vary across seasons. Their results could help cities in different climatic regions design heat mitigation strategies.
