Ideas on transforming cities - Singapore a case study

Ideas on transforming cities - Singapore a case study | green streets |

'We know that the planet is warming up and the human population is growing, raising our demand for resources. The combination of these factors is why the battle against climate change will be decided in cities, particularly cities in the Asia-Pacific.

These urban centres are triple ‘hot spots’: they face rising temperatures, increasing populations and escalating consumption.

To tackle these challenges, we need practical and successful ideas that can easily be replicated.

At the 4th Sustainable Cities Conference last week in Singapore, I discussed ways for Singapore and Hong Kong, already recognised as innovative cities in tackling these problems, to become even greener and establish themselves as leaders in creating sustainable city models for the Asia-Pacific.'

E isso temos que incentivar.

Singapore transformed it's economy faster than any other nation in the world.  It is not surprising to see them leading on other dimensions as well.

10 High-Tech, Green City Solutions for Beating the Heat

10 High-Tech, Green City Solutions for Beating the Heat | green streets |

From a solar mansion in China to a floating farm in New York, green buildings are sprouting up in cities around the world. Among their many benefits are curbing fossil-fuel use and reducing the urban heat island effect...

Heat from North American cities causing warmer winters, study finds

Heat from North American cities causing warmer winters, study finds | green streets |

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.

Climate Change at the Neighborhood Level

Climate Change at the Neighborhood Level | green streets |
Researchers in Los Angeles try out a more granular approach to temperature change estimates.

Most climate maps break down the world into grid squares 200 kilometers wide. That's great for creating a regional picture, but too big for what's happening at the city & neighborhood levels. New work coming out of the UCLA Dept of Atmospheric and Oceanic Sciences greatly improves that resolution, predicting temperature changes in grid sections just two km wide in the Los Angeles region.

The new report, 'Mid-Century Warming in the Los Angeles Region' finds that climate change will likely affect some parts of Los Angeles more heavily than others, with potential temperature increases of between 1.7 and 7.5 degrees F. Inland areas and places at high elevation are predicted to see temperatures rise 20 to 50 percent more than areas near the coast or within the L.A. basin.

This more method of evaluation is an important tool for planners and policymakers, who would like to have more precise information about how to respond to changing temperature levels within cities, and ideally, to pinpoint efforts aimed at reducing those potential impacts...
