Heat from North American cities causing warmer winters, study finds | scatol8® | Scoop.it

Researchers say extra heat generated by huge cities explains additional warming not explained by existing climate models.


Those who wonder why large parts of North America seem to be skipping winter have a new answer in addition to climate change: big city life.

A study, published in the journal Nature Climate Change, found that the heat thrown off by major metropolitan areas on America's east coast caused winter warming across large areas of North America, thousands of miles away from those cities.

 

Scientists have for years been trying to untangle how big cities – with the sprawl of buildings and cars – affect climate. The study suggests cities themselves have far-reaching effects on climate, in addition to the climate pollution caused by the burning of fossil fuels.
