Modeling reveals significant climatic impacts of megapolitan expansion
https://asunews.asu.edu/20120812_urbanclimate[font face=Serif][font size=5]Modeling reveals significant climatic impacts of megapolitan expansion[/font]
Posted: August 13, 2012
[font size=3]According to the United Nations' 2011 Revision of World Urbanization Prospects, global urban population is expected to gain more than 2.5 billion new inhabitants through 2050. Such sharp increases in the number of urban dwellers will require considerable conversion of natural to urban landscapes, resulting in newly developing and expanding megapolitan areas.
Could climate impacts arising from built environment growth pose additional concerns for urban residents also expected to deal with impacts resulting from global climate change?
In the first study of its kind, attempting to quantify the impact of rapidly expanding megapolitan areas on regional climate, a team of researchers from Arizona State University and the National Center for Atmospheric Research has showed that local maximum summertime warming resulting from projected expansion of the urban Sun Corridor could approach 4 degrees Celsius.
This finding, reported in the journal Nature Climate Change, establishes that this factor can be as important as warming that results from increased levels of greenhouse gases.
