Is important remember the that our planet is rapidly urbanizing, in order to understand more about what the human impact of high-end climate change and their risks associated, as pollution, floods, climate change, droughts or floods. By 2050, 70% of the world’s population is expected to become urban.
More than half of the world’s population already lives in urban areas and the number is expected to only increase. Between 2010 and 2030, the urban population is expected to nearly double, growing by an additional 1.5 billion people.
The city’s microclimate, above with global climate change, result in an urban heat island effect. Trees can also contribute indirectly to climate-change mitigation by providing more shade and cooling, thereby reducing overall energy consumption.
Cities and their inhabitants and governments should take in account the increasing number of occurrence of extreme natural events and the social perception.
