Climate change could make cities 8C hotter – scientists

Combination of carbon emissions and 'urban heat island' effect of concrete and asphalt gives rise to worst-case scenario by end of 21st century

Under a dual onslaught of global warming and localised urban heating, some of the world's cities may be as much as 8C (14.4F) warmer by 2100, researchers have warned.

Such a temperature spike would have dire consequences for the health of city-dwellers, rob companies and industries of able workers, and put pressure on already strained natural resources such as water.
