Some examples of direct and indirect impacts of climate change in cities include: Increased temperature: heat stress represents a serious public health concern especially in summers. Urban residents are particularly at risk of heat stress given the fact that higher temperatures occurs in urban regions more than in rural areas due to the 'urban heat island effect' (displayed in Figure 1). Illustrating these impacts, the 2003 summer heat wave in Western Europe has been linked to 35,000 deaths (UN‐HABITAT, 2009). Indirect impacts include the overstress of energy transmission and distribution, due to the increased incidence or duration of summer heat waves, in conjunction with high energy demand for cooling (IEA, 2013).

They can reduce the use of public spaces and thus constrain social life. High temperatures can put infrastructure at risk, including ICT Infrastructure, as fluctuating heat levels can cause continuous thermal expansion and contraction of roads and railroad tracks, physically weakening the construction infrastructure and in the process hamper the supply of goods and movement of commuters. This also adds to maintenance costs (in terms of labour as well as finances) of these structures. (EEA, 2012). Sea level rise: rise in sea level is one of the most well‐known effects of climate change which has proved detrimental to human life and property. One common cause of sea level rise is accelerated glacial melting as a result of increased temperatures due to global warming. Such rises in sea level are unpredictable, and can cause coastal flooding that may lead to loss of life and property (UNFCCC, 2012). Other direct effects of sea level rise include inundation and displacement, coastal erosion and land loss, increased storm flooding and damage, increased salinity in estuaries and coastal aquifers, rising coastal water tables and impeded drainage.
