554City of Paris31175FranceParisC402014More frequent heat wavesExtremely seriousCurrentIt is projected that heatwaves will become more frequent and more intense during the 21st century: from about 1day per year at the end of the 20th century to 10 to 30 days per year by the end of the 21st century. The 2003 heatwave has seriously touched Paris, particularly in terms of surmortality (+1,070 casualties directly due to the heat spell). Other impacts of heatwaves can concern energy distribution, telecommunications, biodiversity, transport system and business continuity.(48.856614°, 2.3522219°)(46.227638°, 2.213749°)
555City of Durban35863South AfricaDurban2014Increased frequency of large stormsSeriousCurrentDurban is already experiencing an increased frequency of large storms. These impact upon the poorest communities the hardest, especially those living in inappropriately situated informal settlements. Impacts of large storms include flooding and loss of private and public property and infrastructure, an increased risk of lightning strikes and damage from strong winds.(-29.8586804°, 31.0218404°)(-30.559482°, 22.937506°)
556Comune di Venezia36254ItalyVeniceC402014More intense rainfallExtremely seriousCurrentMore intense rainfall are being experienced in the whole Venice Region, and it has become systematic to have hydraulic problems during the main rain season (normally november). During the year 2007 the mainland of Venice has undergone a big flooding precipitations so intense as to locally exceed 100mm per hour and 200mm in 3 hours. The intensity of precipitations has led to widespread flooding with reported damages for as much as almost 50 M€ and over 6.000 assistance request from single citizens.(45.4332515°, 12.3210704°)(41.87194°, 12.56738°)
557City of Porto46514PortugalPorto2014Other: Occurrence of inundation and coastal overtoppingSeriousCurrentThe “National Risk Evaluation Report (Jan 2014)” identifies the western area of Porto and the mouth of the Douro River as sensitive points for coastal overtopping affecting beaches in the coastal protection land strip. However, despite a medium/high level of probability, this report has considered it to be of reduced severity as it only implies traffic restrictions and, in the limit, evacuation of people for a short period, with little impact on the community.(41.1579438°, -8.6291053°)(39.399872°, -8.224454°)

560City of Buenos Aires31155ArgentinaBuenos AiresC402014Increased urban heat island effectLess seriousCurrentDue to an increase in the City`s temperature there is an increase on energy consumption and demand during summer. Besides, due to this phenomenon it rains more and there are more rainy days within the central area of the City compared with its borders and surroundings, according to the difference observed between two meteorological stations belonging to the national observational network. Although both stations are close together, they happen to show some differences due to their geographical location in the city: one of them is located in a coastal area, while the other one is emplaced in a central area of the city.(-34.6037232°, -58.3815931°)(-38.416097°, -63.616672°)

579San Salvador35889El SalvadorSan Salvador2014Increased average annual rainfallExtremely seriousShort-termAgriculture: Climate change has a direct effect on agriculture, especially in the subsistence agriculture, as the crops become vulnerable with the increase of droughts or floods. Buildings: It is to consider the vulnerability of the existing infrastructure in the theme of housing, is to consider that much of the urban and semi-urban areas are built on slopes and these following by the increase of rainfall rains are prone to landslides. Water: This resource is extremely sensitive to the effects of climate change, because if we are affected by prolonged droughts, the rainwater capture that feeds the aquifer is lost, also having direct effects on rivers and lakes, as the rivers get lower and may get dry. On the other hand most of rain´s precipitation drive to rivers overflowing, which pollutes especially wells , that directly affect the life in the sector affected Solid Waste: The inadequate or lack of solid waste´s treatment increase the acceleration of climate change, as there are higher concentrations mainly of methane and carbon dioxide, gases that cause global warming among other consequences Transportation: It is important to note that the lack of policies and the lack of control in the transport regulations are responsible for the environmental pollution. Energy : The use of non-renewable energy and the use inefficient of resources that are used to energy production threaten its sustainability; in our case more than 80% of energy is produced by water resources that will be affected directly as a result of climate change Communications: The whole communication system is supported by the power generation, this being due to points discussed above, will suffer directly. Human health: Human health will be the most vulnerable element to the eminent climate change, the development of our cities is based on power generation and the production structure which is intimately linked to the consumption of energy, whereas human health is directly threatened by pollution and the respective deterioration what it produces, as well as food vulnerability and the quality of water resources mainly , these make human health be directly threatened by pollution(13.6929403°, -89.2181911°)(13.794185°, -88.89653°)
580City of Cleveland35859USACleveland2014More hot daysSeriousShort-termDuring heat waves, high electricity demand combines with climate-related limitations on energy production capabilities, increasing the likelihood of electricity shortages and resulting in brownouts or even blackouts. Warming also decreases the number of days with snow on the ground, which may improve traffic safety. In winter, oil and gas demand for heating would also decline.(41.49932°, -81.6943605°)(37.09024°, -95.712891°)
581City District Government Karachi31168PakistanKarachiC402014More hot daysSeriousLong-termIn the absence of a good public transport system and any mechanism for the fitness of vehicles, indiscriminate dumping of Solid Waste and its burning has increased tremendous amount of emission of GHG's which leads towards the increase of temperature(24.9107179°, 67.1283309°)(30.375321°, 69.345116°)
582Alcadia Distrital de Barranquilla43970ColombiaBarranquilla2014Change in seasonality of rainfallSeriousMedium-termActually drought conditions have alarms generated by the decrease in the availability of water resource, besides the agricultural economy is directly affected by this situation. Excessive rain has created flooding problems leaving a large number of victims across the Department Atlantic that has generated migration to the capital of the department that is Barranquilla. The increased rainfall also has impacts on the city in economic matters.(10.9815944°, -74.7782214°)(4.570868°, -74.297333°)
