Urban areas experience higher temperatures compared to rural areas, and it is likely that this will lead to health risks within urban communities due extreme heat in the future. However, we have the power to minimize this effect by improving the infrastructures of our cities. An effective way to lower urban temperatures is increasing vegetation and water surfaces, which also provides the added benefit of increasing urban biodiversity, and improving air quality. While this known to be a valid strategy, the magnitude of the climate impact that such an improvement will have when applied on a city scale is unknown. Žuvela-Aloise et al. (2016) have modeled the potential of improving green and blue infrastructure within Vienna, and identified the ways in which changes should be applied in order to counteract urban warming as effectively as possible.
Global ambient temperatures keep rising year by year, and urban areas specifically experience higher temperatures compared to rural areas due to lower vegetation coverage and increased emissions. An effective strategy to counteract this problem is to expand green spaces and improve urban forestry. However, it is important to ensure that the greenery that we integrate into our cities can withstand changing climate conditions as ambient temperatures keep increasing at a rate faster than ever. Lanza and Stone (2016) focus on how global warming has affected the climate conditions around 20 highly populated metropolitan areas in USA, and the impact that this has had on present tree species.
