Sentences with phrase «reducing city temperatures»

Not exact matches

The researchers estimated that areas of the city could reduce average summertime temperatures by as much as 1.7 degrees C or more.

New York's Mayor Michael Bloomberg has committed city funds to converting some of the area's black tar and stone roofs into highly reflective white roofs, which reduce temperatures on roofs and cooling costs but fail to address the storm water runoff problem.

A city's water availability, through rainfall or irrigation, dictates its evaporative cooling effects on temperature, which reduces the severity of a heat wave.

As many as 3,331 people annually could die from heat waves by 2080 in New York City alone if no steps are taken to adapt to warming temperatures and reduce emissions, a new study warns.

Colorado led the way in 1988 when Denver became the first city to introduce the additives on the basis of research claiming that they helped the fuel's hydrocarbons to burn more efficiently at low temperatures, thereby producing more carbon dioxide than CO and also reducing emissions of the polluting hydrocarbons themselves.

Pavements, including roads and parking lots, can cover one - third or more of a typical U.S. city, and previous studies have shown that cool pavements can reduce a city's average outside air temperature by around 0.5 degrees Celsius, depending on the extent of deployment, city size, and city location.

«New urban heat island study shows surprising variation in air temperatures across Twin Cities: Results provide valuable insights into efforts to reduce heat - related harm in metro areas globally.»

Innovative urban design could create increased access to active transport.99 The compact geographical area found in cities presents opportunities to reduce energy use and emissions of heat - trapping gases and other air pollutants through active transit, improved building construction, provision of services, and infrastructure creation, such as bike paths and sidewalks.303, 318 Urban planning strategies designed to reduce the urban heat island effect, such as green / cool roofs, increased green space, parkland and urban canopy, could reduce indoor temperatures, improve indoor air quality, and could produce additional societal co-benefits by promoting social interaction and prioritizing vulnerable urban populations.311, 303

A mature tree canopy in a city shades buildings and can reduce air temperatures by 5 — 10 degrees Fahrenheit, thus reducing the energy needed for air conditioning.

More reflective roofs can reduce a household's energy bill, as well as the overall temperature of a city.

Hence, strategies to reduce urban emissions are essential to solving the climate crisis and cities will play a vital role in achieving the carbon reduction targets required to keep the earth at a viable temperature.

«In cities, it could potentially help reduce the highest temperatures to reduce health problems for the population during heatwaves.

In a program partly sponsored by the New York City government, white synthetic surfaces and paints were found to reduce peak rooftop temperatures by 24 °C (43 °F) compared to typical black rooftops.

It has long been observed that temperatures in cities are higher than in the surrounding countryside, caused, in part, by human structures that reduce albedo and evapo - transpiration, as well as by the effects of waste heat emissions, McCarthy et al 2010.

To minimise the risks of heat stress that are most pronounced in large cities due to the urban heat - island effect in summer (Kalnay and Cai, 2003) urban planning should consider: reducing the heat island in summer, the heat load on buildings, cooling load and high night - time temperature, and taking climate change into account in planning new buildings and setting up new regulations on buildings and urban development.

Rosenzweig et al. (2005) found that climate change based on downscaled general circulation model (GCM) projections would exacerbate the New York City UHI by increasing baseline temperatures and reducing local wind speeds.
