Climate change could make cities 8ÂºC hotter by 2100: Study
Continued global warming and urban heating (replacing greenery and lakes by concrete) could take city temperatures 8ÂºC higher by 2100, researchers have warned. Cities cover 1% of Earth's surface but account for 60% of global carbon emissions, researchers said. The study of 1,692 largest cities from 1950 to 2015 further mentions the worst-hit city could lose 10.9% GDP by 2100.
