Este hecho se debe a que las lluvias intensas (desencadenante climático del fenómeno de movimientos en masa) incrementan progresivamente a medida que aumenta el horizonte temporal y el escenario climático. Dentro de cada escenario y horizonte temporal, los niveles de riesgo más altos se encuentran asociados a las diferentes quebradas, laderas del Pichincha y elevaciones volcánicas puesto que presentan una mayor susceptibilidad a los movimientos en masa, en comparación con la zona urbanizada de Quito, cuyas zonas periféricas son las que registran el mayor riesgo al ser las más susceptibles.Así, en los receptores de hábitat urbano y población los niveles de riesgo más altos se concentran en las zonas periféricas de las parroquias urbanas. Estas zonas no solo son las áreas más susceptibles a movimientos en masa, sino que son las más vulnerables; esto es, son las zonas que poseen un nivel socio-económico más bajo, viviendas de calidad constructiva más baja y una mayor densidad de población. | |

Por otra parte, los ríos que discurren en valles inundables de bajas pendientes pueden fluir por ellas dejando cauces abandonados e inundando nuevos terrenos.Las inundaciones, además, son provocadas por causas antrópicas, como taponamiento y rotura de sistemas de recolección de aguas lluvias y alcantarillado o colectores, relleno de los drenajes naturales (quebradas), impermeabilización de suelos que aumenta la cantidad y la velocidad del agua a evacuarse, tala de bosques, inadecuado uso de suelo, construcciones y asentamientos humanos cerca de las vertientes de agua y en las franjas de protección de cuencas hidrográficas, entre otras.Los niveles de riesgo más altos tienen lugar fundamentalmente en las parroquias urbanas del DMQ, donde los eventos de precipitaciones intensas presentan mayor problemática debido a las bajas pendientes y a la falta de capacidad hidráulica del sistema de alcantarillado en algunos puntos. Así, en el caso del receptor hábitat urbano, los niveles de riesgo relativamente más elevados se registran en general en la zona urbana del DMQ, resultado en su mayoría del cruce de las edificaciones con vulnerabilidad a inundaciones moderada y un nivel de peligrosidad alto o muy alto. La vulnerabilidad está asociada a la calidad constructiva de las edificaciones en combinación con el nivel socioeconómico de cada manzana.Respecto al receptor población, la situación de la población en zonas de riesgo alto y muy alto representa un 9% y un 22%, para los escenarios RCP 4.5 (2016-2040) y RCP 8.5 (2041-2070), respectivamente. | |

Es debido a que el nivel de amenaza es asimismo muy alto en todo el territorio y, por consiguiente, su exposición. Las variaciones que existen en el nivel de riesgo se deben a la componente de vulnerabilidad. Considerando el receptor “hábitat urbano”, por ejemplo, predomina un nivel de riesgo “Alto” y “Muy alto” con un total del 97% de la superficie del DMQ. Este nivel se debe no solo a la alta peligrosidad, sino también a la alta y/o moderada vulnerabilidad, que viene caracterizada por el bajo nivel socioeconómico de la población y la baja accesibilidad de las zonas verdes.A destacar la espacialización del riesgo en relación a los espacios naturales, vinculado a la sensibilidad frente a incendios forestales. Como es de esperar, el mayor riesgo se concentra en las laderas con altas pendientes y orientación sur y sureste.Las consecuencias de la isla de calor urbana son muy variadas, desde la reducción del gasto energético por uso de calefacción en invierno hasta el aumento de la demanda por refrigeración en verano, con especial agravio en eventos de calor extremo como las olas de calor y sus consiguientes riesgos para la salud, así como la propia alteración de la flora y fauna urbanas. | |

The city’s infrastructure is aging, and in the event of a 100 year flood event as much as $3.6 Billion in damage is estimated. The ongoing Deep Rock Tunnel project is aimed to mitigate the potential impact of such events but is unlikely to eliminate it altogether. City is also implementing a 20-year, $320 million storm water capital improvement program to eliminate identified neighborhood flooding and drainage issues. In 2016, severe flooding occurred causing 15,000 residents to lose power. Between 2013 and 2018, there were 15 floods and 22 flash floods causing a total of $377.8 thousand dollars in damages. Spring and Summer of 2019 have been some of the wetter months on record according to Weather.gov. Average rainfalls from February through April were well above the 2.3 to 3.8 inch averages. May’s precipitation was slightly above average at 4.96 inches, but June’s precipitation was close to double the average at 7.51 inches. July and August both hovered near the average. May 2020 recorded 7.13 inches of precipitation above the 4.75 inch normal. However, April was well below average at 1.72 inches. The rest of the spring and summer averaged near normal rainfall.

Hotter summers will also result in increased education costs. Currently, Indianapolis Public Schools sends children with asthma to air conditioned schools. Schools without air conditioning will need to find ways to provide a comfortable learning environment. Increased heat waves in intensity and duration typically produce air quality stagnation which increases PM2.5 and ozone levels. Public health faces greater jeopardy not only from the heat but also the deterioration of air quality associated with it. Children, older adults, those with underlying health issues, and anyone working outdoors are at a greater risk. In addition, increases in pollution levels reduce crop yields and also decrease the visibility, both of which have economic and quality of life impacts. The last heat wave recorded by NOAA was in 2000, which resulted in one death. In 2017, there was a heat wave in Marion County that included multiple days with heat indices of approximately 100 degrees. | |

A study from 2018 found that though the number of tornadoes in the United States hasn't increased significantly, but the locations of the tornados are shifting more from the Great Plains area to the Midwest, including Indiana. Tornadoes in 2016 and 2014 damaged 100 homes and over 200 vehicles. In 2019, Marion County saw an EF0 and an EF1 tornado, which were the first confirmed touchdowns since 2016. Minor damage resulted. In 2020, Marion county did not experience any tornadoes but adjacent Johnson county reported an EF1 tornado on April 8th, no injuries or deaths were reported.

The risk for heat-related health impacts is highest amongst infants, young children, the elderly over 65, those already ill, athletes, those spending time outside, including outdoor workers, those engaging in physical activity, and those who don’t have access to air conditioning (Climate Central, “U.S. faces dramatic rise in extreme heat, humidity”, 2016), as well as those in more urban areas within the city, due an increase in the Urban Heat Island effect (Environmental Protection Agency & Center for Disease Control, 2016). Since 9.4% of Orlando’s residents are over the age of 65, 7.1% are under five years old, and one-in-five of all residents (20.2%) live at or below the poverty line, which is above average among the lower 48 states (U.S. Census Bureau, 2017), we have a large representation of groups are considered to be especially vulnerable to extreme heat. Furthermore, during dangerously hot days, the risk for these heat-related effects sharply increases and can reach even healthy young adults to middle-aged individuals. According to current predictions, annual heat-related deaths will increase to tens-of-thousands by the end of the century (Climate Central, “U.S. faces dramatic rise in extreme heat, humidity”, 2016), and, with the projections for our region, many of these deaths will occur in Central Florida. For individuals and families with pets that spend some or all of their time outside or do not have air conditioning, this also presents a serious risk (Florida Division of Emergency Management, 2013). These heat impacts may also provide a strain on the healthcare system when faced with increased hospitalizations and doctors’ visits, need for home care, and insurance claims. (Climate Central, “U.S. faces dramatic rise in extreme heat, humidity”, 2016).The impacts from high heat also interact with other climate hazards that can result in amplified risks. This elevated heat can contribute to stagnant air, which has been increasing in Central Florida, and allows dangerous levels of both air pollutants and ground-level ozone to build up in the local area (Climate Central, “Stagnant air on the rise, upping ozone risk”, 2016). | |

Carbon monoxide poisoning can occur during or after the storm has passed if gas-powered generators are placed in an area without proper ventilation, as occurred during the series of Florida hurricanes in 2005. Additionally, populations sensitive to heat, such as the elderly, may be left without power for air conditioning for extended periods of time resulting in injury and fatalities, as tragically occurred in South Florida after Hurricane Irma (Fritz, 2017; Ochoa, 2017). Finally, foodborne illness can result due to lack of power for refrigeration, and water-borne illness from drinking or preparing food with water that has been contaminated from the strains on water reclamation facilities and other sources of water pollution (Florida Department of Health, 2015). | |

However, since this industry is very limited in Orlando, the impacts are more likely to be first seen across surface water in the City’s lakes and streams, as well as subsurface ground water upon which we depend for our potable water for drinking, plumbing, and irrigation. Impacts on local flora and smaller community gardens and urban agriculture may also be experienced.The effect of droughts in the region would also be dangerous for its impacts on other hazards. By lowering water tables and compromising the integrity of soil for holding large amounts of water, droughts present an elevated risk for sinkholes. The dry conditions also raise the risk for wildfires.The local impacts of water regulations could impact the hospitality and tourism sectors, including the water-based attractions at local theme parks, attractions, and hotels, as well as local ecotourism, such as tubing, paddleboarding, and kayaking in local lakes, streams, and springs. Since these industries represent a large portion of the local economy, these impacts could have a significant negatively influence. Additionally, with damages to the statewide agricultural industry, prices on a number of crops, including oranges, grapefruit, sweet corn, watermelons, cucumbers, squash, snap peas and sugar cane, as well as beef, could rise due to reduced supply. | |

The total value of structures at risk for wildfire damage (broken down by occupancy type in the table above) in Orange County is $17,197,000,000, with an estimated annualized loss of $1,405,000 and the total value of County facilities (shown with values in table below) is $1,454,500,000 with an estimated annualized loss of $32,610 (Florida Division of Emergency Management, 2013). The greatest loss potential lies in the single-family residential homes, many of which lie within the WUI in Orlando.Any wildfire activity will result in damage to forested lands and protected natural lands that provide habitats and nesting areas for local wildlife and valuable biodiversity within the region (Florida Division of Emergency Management, 2013), which could negative economic impacts not only for the previously occupied structures, but also future development potential in the area.There is also a possibility for death and injuries, although less common, during the early stages of wildfires and throughout the process of evacuation. A higher risk of harm exists for responders involved in the fire suppression, particularly if the fire grows or suddenly changes directions.Other dangers include possible transportation disruption across the interstate system, as was the case during Florida wildfires in 2012, which can affect local residents as well as the many visitors to the region. | |

In 2018, the city set a new annual precipitation record of 55.18 inches and 2019 the city's annual precipitation was 43.94 inches, when the average annual value is 39.31 inches. Heavy rain has led to flooding of basements and road closures. Models project those trends will continue, creating major vulnerabilities to energy and water infrastructure, health, and transportation. https://byrd.osu.edu/sites/byrd.osu.edu/files/CCAP%20-%20Flooding.pdf | |

From the 1951-1980 period to the 1981-2010 period, the amount of precipitation falling during the heaviest 1% of precipitation events increased by 36.2%. Models project those trends will continue, increasing flood damage risks to infrastructure. The Department of Public Utilities is creating a tool that involves collaboration between DPU, the Department of Public Safety, Columbus Police, and Columbus Fire on the creation of roadway routing for emergency and residential vehicles. While this tool would only be used during major river flooding, it would be a first step to identifying and communicating transportation routes. anhttps://byrd.osu.edu/sites/byrd.osu.edu/files/CCAP%20-%20Flooding.pdfd public health. | |

Fall precipitation increased dramatically, by 43.5% (3.2 inches). As temperatures warm and precipitation increases, the form and timing of precipitation will likely change. The number of days dry enough to plant crops in the spring may be reduced and the potential for rain on semi-frozen ground may increase. The agricultural sector will likely see an increased need for irrigation and controlled drainage and may need to treat livestock for infection and disease. The City will likely see increased infrastructure and property damage due to extreme weather and flooding. | |

To reduce residents' vulnerability to sun exposure and intense heat, some city recreation centers extended their hours . Mayor Ginther released the following statement: “I encourage residents to take care during extreme heat,” said Mayor Ginther. “Our community centers are a safe place to cool off.” Temperatures are expected to continue rising and the frequency of extreme heat days are predicted to increase. In the future, Columbus may need to keep recreation centers open more often to ensure resident safety and will need to create a more robust public-private network of resilience hubs for residents to use during extreme weather events. This pace of extremely hot days continued into 2019 with a similar extended extreme heat event occurring in late July 2019. https://www.10tv.com/article/news/local/5-columbus-rec-centers-remain-open-weekend-help-people-beat-heat-2019-jul/530-dbce69d9-0f17-450d-bc6e-ce0c2030e861.

During elevated river levels, flow in storm sewers may reverse direction and flow from the river into protected areas. Floodgates and backflow preventers are designed to restrict water flow from inundating these protected areas, but this could be an area of impact in the future. There could be an increased need for water treatment due to deteriorated water quality. | |

For the purposes of Edmonton VRA, this was defined as an event with accumulated snowfall of at least 50 cm. A heavy snowfall causes transportation disruptions and can also increase the likelihood of car accidents with associated injuries and fatalities. It can also increase the incidence of heart attacks from snow shoveling. Both these impacts put additional stress on emergency management services and personnel. Newer homes and buildings in the city are designed to withstand a larger snowfalls; however, some older structures may be challenged by new snow loads. The consequences for Edmonton's electricity grid could be widespread, but impacts would be short-lived and less serious. The extent of the impacts depends on the duration and timing of the event. A heavy snow event in May or September, when there are leaves on the trees, could cause significant tree damage and increase the likelihood of power outages. Vulnerable populations include low income individuals living in older, less structurally sound homes that are less able to withstand heavy snow loads. A power outage in the middle of winter can have a significant impact on the homeless and low income individuals and families. Individuals predisposed to heart failure and disease are also particularly vulnerable. | |

For the purposes of Edmonton VRA, these are defined as wind gusts reaching or exceeding a speed of 90 km per hour.Regarding the built environment, severe winds can affect buildings and construction sites, potentially blowing siding, shingles, and solar panels off houses, blowing over cranes, or blowing debris off construction sites. Damage to buildings and property is exacerbated when winds are widespread and longer lasting. If widespread, a severe wind event impacting a major construction site could result in injuries and fatalities, with major implications for emergency management services. Severe wind can impact the environment, notably the urban canopy, damaging trees, which will increase maintenance costs and disrupt access to parks. Depending on the number of downed trees, this could have a major impact on waste management services, which is not equipped to collect tree debris. Other environmental impacts from severe wind could include soil erosion with potential consequences for vegetation germination, and mixing layers in the water column, which could lead to the development of cyanobacteria. Telecommunications and electricity transmissions infrastructure is built to withstand this level of wind event. However, electricity distribution lines could be impacted, with some isolated power outages. Vulnerable populations include the homeless and low income individuals and families. These populations have limited ability to take shelter during a severe wind event, and tend to live in older, lower quality homes that are less able to withstand winds without experiencing damage. These vulnerable populations also have difficulty evacuating and often don't have access to private automobiles. | |

For Edmonton's VRA, this hazards was defined as years with one or more freezing rain events meeting the minimum Environment and Climate Change Canada's warning criteria.Freezing rain is rain that freezes on impact to form a coating of clear ice on the ground and on exposed objects. Freezing rain has the most severe impacts on the following asset and service areas: road transportation, electricity system, and information and communications infrastructure.Regarding the road network, freezing rain causes increased maintenance costs and can also lead to vehicle accidents with associated injuries and fatalities. Freezing rain on surfaces also increases the risk of slips and falls, leading to injuries.Freezing rain will affect electricity distribution infrastructure, leading to increased incidence of power outages, as well as delays in restoring power following an outage (due to concurrent disruption to the road network). High voltage lines will experience some sagging, but if they failed the impacts could be more widespread and significant. A major power outage affecting the downtown core would have major impacts.Information and communications infrastructure, primarily microwave towers, could also be impacted by freezing rain causing service losses. Indirect impacts associated with power outages and telecommunication disruption could be widespread, and affecting multiple service areas: water supply, buildings, rail transport, public health and safety and the economy. No specific vulnerable populations were identified. | |

For the purposes of Edmonton's VRA, heat wave conditions are defined as five consecutive days with maximum temperature greater or equal to 29 degrees Celsius.Regarding the rail network, heat waves can lead to "sun kinks" on the rail line, damaging rail infrastructure and causing transport disruption, with indirect economic impacts due to supply/customer chain disruption. Heat waves can also impact road transportation, including bus transit services, causing overheating. Vulnerable populations, such as the homeless who have limited ability to take shelter during a heat wave, and low income individuals and families who have limited ability to pay space cooling costs (or have access to air conditioning), are particularly at risk to adverse health outcomes. Another vulnerable group are people who work outdoors. Individuals among these groups with existing pulmonary or cardiovascular conditions are most at risk. There are proven associations between heat stress and a range of adverse health effects. Health risks are compounded if extreme heat is accompanied by weather conditions conducive to the formation of smog or a general deterioration in air quality. An intense, long duration heat wave has potential to cause power outages associated with high air conditioning use and reduced efficiency on lines; accompanied by adverse health impacts associated with heat stress, this could lead to an emergency situation. Historically heat waves in Edmonton have not been as common as cold spells, and the city is not as prepared to deal with severe heat waves. | |

For the purposes of Edmonton's VRA, extreme hot days are defined as a day with maximum temperature greater or equal to 29 degrees Celsius.A single hot day could give rise to adverse health outcomes among particularly vulnerable groups; individuals with existing pulmonary or cardiovascular conditions, living along, and unable to mitigate exposure or sensitivity to the heat due to socio-economic circumstances. There is a small risk of rail snaking. Users of public transport may also experience some discomfort due to overheating on buses. | |

For the purposes of Edmonton's VRA, drought was specifically defined by a Palmer Drought Severity Index (PDSI) value of -2 or below.Droughts can have consequences on the urban forest, parks, and aquatic environment in Edmonton. Birch trees can be particularly impacted due to their shallow root systems which cannot tolerate drought. Drought can impact aquatic life, via reduced water levels and increased water temperature, which can lead to a deterioration in water quality. Compared to other parts of the province, Edmonton's food system is not very well equipped to deal with drought. Drought will affect commercial crops and home and community gardens, causing reduced productivity and in extreme cases crop failure. Most crops in the Edmonton area are not drought resistant. Reduced agricultural output will have indirect economic impacts on supply/customer chains, though commercial losses will likely be insured. For the water supply system, drought can reduce available water supply and could lead to water use restrictions. |
