958City of Johannesburg31115South AfricaJohannesburgC402015Temperature Increase/HeatwavesExtremely seriousCurrentA clear trend of average maximum temperatures has been observed. From time to time, Johannesburg will experience heatwaves. This will lead to heavy use of water and electricity. Furthermore, heatwaves can lead to loss of life.(-26.2041028°, 28.0473051°)(-30.559482°, 22.937506°)
959City of Buenos Aires31155ArgentinaBuenos AiresC402015Frequent/Intense RainfallLess seriousCurrentRegarding the evolution of the annual accumulated precipitation for the reference stations for the period 1960-2011, significant trends show an increase in the annual precipitation accumulated of about 5 mm per year, which represents an increase in annual precipitation of 20% in the 62 years analyzed(-34.6037232°, -58.3815931°)(-38.416097°, -63.616672°)

Increased wildfire risk to watersheds and risk of interuptions to electricity transmission and the operations of hydroelectric projects.(47.6062095°, -122.3320708°)(37.09024°, -95.712891°)

963City of Sydney31114AustraliaSydneyC402015Storms/FloodsSeriousCurrentRisks: displacement, property/infrastructure damage, flash flooding, localised power infrastructure damage, overflow contaminants, reduced amenity, changed biodiversity, food security, communication disruption. Climate models for rainfall indicate the potential for both increases and decreases which provides a low level of certainty. El Nino remains the greatest uncertainty in projecting the future climate of eastern Australia.(-33.8674869°, 151.2069902°)(-25.274398°, 133.775136°)
964Prefeitura do Rio de Janeiro31176BrazilRio de JaneiroC402015Temperature Increase/HeatwavesSeriousShort-termIt is estimated an increase in annual water consumption by 20%, pushing the water demand on the supply and sanitation public system. For the 2nd half of the century, a general increase in temperature, hotter nights, heat waves and extreme rainfall events are expected.(-22.9054389°, -43.5614471°)(-14.235004°, -51.92528°)
965City of San Francisco31182USASan FranciscoC402015DroughtExtremely seriousCurrentImpacted Sectors: Community-wide, Business and Residential, Water Utility, Wastewater Utility, Buildings, Transport, SF Recreation and Parks.(37.7749295°, -122.4194155°)(37.09024°, -95.712891°)

967City of Pittsburgh35877USAPittsburgh2015OtherSeriousCurrentHazardous conditions, increased labor and maintenance cost to local government (road maintenance, increase in need for public heating centers, etc.)(40.4406248°, -79.9958864°)(37.09024°, -95.712891°)
968Prefeitura de Florianópolis50384BrazilFlorianópolis2015Temperature Increase/HeatwavesSeriousShort-termGreater energy expenditure. More greenhouse gases.(-27.5949884°, -48.5481743°)(-14.235004°, -51.92528°)
969City of Paris31175FranceParisC402015DroughtSeriousLong-termMore intense droughts might cause problems for water supply (at least the part coming from surface waters). Other potential impacts include low water flow and thus potential impacts on goods transport through river transport. Impacts on biodiversity (possibility of a higher risk for forest fires) and potential impacts on energy distribution (particularly for the cold and heat urban networks).To a lesser extent, potential impacts on buildings (with the swelling-shrinking movements of some clay soils)(48.856614°, 2.3522219°)(46.227638°, 2.213749°)
970Tokyo Metropolitan Government31111JapanTokyoC402015Frequent/Intense RainfallCurrentReduced quality of river and reservoir water - Accidents caused by river water rise and surface water flooding(35.6896342°, 139.6921007°)(36.204824°, 138.252924°)
971City of Los Angeles10894USALos AngelesC402015Sea Level RiseExtremely seriousLong-termWould impact the City's power plants near the sea that use sea water to cool equipment.(34.0522342°, -118.2436849°)(37.09024°, -95.712891°)
972Greater Manchester35898United KingdomManchester2015Storms/FloodsSeriousMedium-termimpacts/disruption to transport and other infrastruture and services which support both community and economic activiites in GM(53.4575955°, -2.1578377°)(55.378051°, -3.435973°)
973Mexico City31172MexicoMexico CityC402015Frequent/Intense RainfallExtremely seriousCurrentThe inumber of extreme rain events in Mexico City shows an increased trend since this parameter has been recorded in the late XIX Century. This provokes that the floods become more intense.(19.4326077°, -99.133208°)(23.634501°, -102.552784°)
974City of Sydney31114AustraliaSydneyC402015Frequent/Intense RainfallSeriousCurrentRisks: displacement, property/infrastructure damage, flash flooding, localised power infrastructure damage, overflow contaminants, reduced amenity, changed biodiversity, food security, communication disruption. Potential changes in frequency and distribution of large storm events is largely unknown, and it is these extreme events that cause the most damage and therefore present the greatest risks. The CSIRO and Bureau of Meteorology's 2013 State of the Climate report suggests that average rainfall in southern Australia is projected to decrease, and heavy rainfall is projected to increase over most parts of Australia.(-33.8674869°, 151.2069902°)(-25.274398°, 133.775136°)
975City of Vancouver20113CanadaVancouverC402015Temperature Increase/HeatwavesLess seriousMedium-termIncreased health and safety risks to vulnerable populations; water supply pressures in late summer; increasing vectors for disease and respiratory illness are all expected with hotter, drier summers.(49.261226°, -123.1139268°)(56.130366°, -106.346771°)
976City of Edmonton43912CanadaEdmonton2015Temperature Increase/HeatwavesExtremely seriousMedium-termOur water supply is heavily dependent upon snow Pack in the mountains which has noticeably decreased over the years. Water supply could be in jeopardy in the future.(53.544389°, -113.4909267°)(56.130366°, -106.346771°)
