Global Warming

Hotter Cities

New research finds that a combination of global warming and localized heating due to the urban heat island (UHI) effect could cause some of the world’s cities to be as much as 14 degrees Fahrenheit warmer by the end of this century.

The UHI effect occurs as buildings, roadways and other man-made structures store far more heat than natural settings, especially after the sun goes down. This amplifies the local warming effects of climate change, according to a report published in the journal Nature Climate Change.

Scientists recommend painting roofs a reflective white and planting more trees to limit urban warming.
