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.

Very interesting reading this. It seems quite true since the past winter didn't seem as cold as most winters here in Rhode Island. If the big cities cause the winter to be less cool then in the future, would winter even be cold? Lets hope and say this problem will never happen.
