Heat from North American cities causing warmer winters, study finds

Heat from North American cities causing warmer winters, study finds | Développement durable et efficacité énergétique | 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.

Brittany Ortiz's curator insight, September 29, 5:15 PM

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.

The Cost of Sprawl on Clean Water

The Cost of Sprawl on Clean Water | Développement durable et efficacité énergétique | Scoop.it
The way we grow could have a major impact on water quality in the future.

Sustainable, smart growth and development is necessarily about location, form and function. Becoming greener doesn’t just mean a municipality’s adding a pleasant new park here and there, or planting more trees, although both components may be useful parts of a larger effort.

How a town is designed and developed is related to how well it functions, how well it functions is related to how sustainable it really is, and how sustainable it is, is directly related to how it affects its local waters and those who use those same waters downstream...

Top 10 best and worst cities to live | SmartPlanet

Top 10 best and worst cities to live | SmartPlanet | Développement durable et efficacité énergétique | Scoop.it
A new ranking measures city characteristics like sprawl, green space, and pollution to determine livability.

The Economist Intelligence Unit — the city rankings specialists — has a new list claiming the best cities to live. And they have an interesting new livability metrics to judge the world’s cities.

The rankings combined EIU’s popular “Liveability Index” with a new measure that focuses on spatial characteristics. The “Spatially Adjusted Livability Index” takes into account seven characteristics:

 

-Sprawl: using the ”estimated relation between the metropolitan region’s surface and its total population, the overall coherence of the metropolitan form and an estimate of the extent of low density urban fabric.”

-Green space: based on ”the distribution of green spaces within the metropolitan region, the number of local green spaces and the number of metropolitan scale green spaces.”

-Natural assets: using “Google Earth satellite imagery and information from Open Street Map to assign points to cities based on the natural features” and the number of protected areas around a city center.

-Cultural assets: counting the number of UNESCO World Heritage Sites in the vicinity of the cities.

-Connectivity: calculating how many cities can be reached by plane from a city and the average number of flights from that city.

-Isolation: based on the number of large cities near a city.

-Pollution: using World Health Organisation (WHO)’s Air Pollution in Cities database to calculate air quality with a concentration of particulate matter of over 10 micrometres...
