101-587: The Cape Town Cycle Tour , formerly known as the Cape Argus Cycle Tour , is an annual cycle race hosted in Cape Town , South Africa, usually 109 km (68 mi) long. It is the first event outside Europe to be included in the Union Cycliste Internationale 's Golden Bike Series . South Africa hosts some of the largest, by the number of entrants, sporting events in the world with three being

202-553: A 1970 cyclone killed 300,000, the similarly-sized Cyclone Ampham , which struck India and Bangladesh in 2020, killed just 120 people in total. On July 23, 2020, Munich Re announced that the 2,900 total global deaths from natural disasters for the first half of 2020 were a record-low, and "much lower than the average figures for both the last 30 years and the last 10 years." A 2021 study found that 9.4% of global deaths between 2000 and 2019 – ~5 million annually – can be attributed to extreme temperature with cold-related ones making up

303-515: A prison where people were isolated, banished, and exiled for nearly 400 years. It was also used as a leper colony, a post office, a grazing ground, a mental hospital, and an outpost. The Cape Peninsula is a rocky and mountainous peninsula that juts out into the Atlantic Ocean at the south-western extremity of the continent. At its tip is Cape Point and the Cape of Good Hope . The peninsula forms

404-510: A severe water shortage from 2015 to 2018. According to Oxfam , "in the face of an imminent water shortage, the city of Cape Town in South Africa successfully reduced its water use by more than half in three years, cutting it from 1.2bn litres per day in February 2015 to 516m litres per day in 2018." In 2021 Cape Town also experienced a violent turf war between rival taxi firms which led to

505-429: A 'climate-related event' refers to floods, storms, droughts, landslides, extreme temperatures (like heat waves or freezes), and wildfires; it excludes geophysical events such as volcanic eruptions, earthquakes, or mass movements. While there is evidence that a changing global climate, such as an increase in temperature, has impacted the frequency of extreme weather events, the most significant effects are likely to arise in

606-451: A 2023 study, "weak extreme cold events (ECEs) significantly decrease in frequency, projection area and total area over the north hemisphere with global warming. However, the frequency, projection area and total area of strong ECEs show no significant trend, whereas they are increasing in Siberia and Canada." A tropical cyclone is a rapidly rotating storm system with a low-pressure center,

707-452: A Summer of 1816, one of several years during the 1810s in which numerous crops failed during freakish summer cold snaps after volcanic eruptions reduced incoming sunlight. In some cases more frequent extremely cold winter weather – i.e. across parts of Asia and North America including the February 2021 North American cold wave – can be a result of climate change such as due to changes in

808-439: A closed low-level atmospheric circulation , strong winds, and a spiral arrangement of thunderstorms that produce heavy rain and squalls . Depending on its location and strength, a tropical cyclone is called a hurricane ( / ˈ h ʌr ɪ k ən , - k eɪ n / ), typhoon ( / t aɪ ˈ f uː n / ), tropical storm, cyclonic storm, tropical depression, or simply cyclone. A hurricane is a strong tropical cyclone that occurs in

909-860: A cold wave is accompanied by heavy and persistent snow, grazing animals may be unable to reach necessary food and water, and die of hypothermia or starvation. Cold waves often necessitate the purchase of fodder for livestock at a considerable cost to farmers. Human populations can be inflicted with frostbite when exposed for extended periods of time to cold and may result in the loss of limbs or damage to internal organs. Extreme winter cold often causes poorly insulated water pipes to freeze. Even some poorly protected indoor plumbing may rupture as frozen water expands within them, causing property damage. Fires, paradoxically, become more hazardous during extreme cold. Water mains may break and water supplies may become unreliable, making firefighting more difficult. Cold waves that bring unexpected freezes and frosts during

1010-408: A competitor's age group belongs to Penny Krohn , who scored 25 such age group wins. By far the quickest time ever recorded (and highest ever average speed) was set on the 105 km course in 1993 by Wimpie van der Merwe in his fully faired recumbent (02:16:40, averaging 46.1 km/h). The oldest cyclist to complete the race within the maximum allowed seven hours is Japie Malan (92 years old at

1111-603: A few other towns. Industry and commerce is largely in service of the area. After the Cape Peninsula, Helderberg is the next most mountainous part of Greater Cape Town, bordered to the north and east by the highest peaks in the region along the watershed of the Helderberg and Hottentots Holland Mountains, which are part of the Cape Fold Belt with Cape Supergroup strata on a basement of Tygerberg Formation rocks intruded by part of

1212-671: A flood of immigration into South Africa. In 1895 the city's first public power station, the Graaff Electric Lighting Works , was opened. Conflicts between the Boer republics in the interior and the British colonial government resulted in the Second Boer War of 1899–1902. Britain's victory in this war led to the formation of a united South Africa. From 1891 to 1901, the city's population more than doubled from 67,000 to 171,000. As

1313-421: A floodplain puts residents at increased risk of destruction or injury in an extreme precipitation event. More urban areas can also contribute to the rise of extreme or unusual weather events. Tall structures can alter the way that wind moves throughout an urban area, pushing warmer air upwards and inducing convection, creating thunderstorms. With these thunderstorms comes increased precipitation, which, because of

1414-818: A heatwave vary because of the variation of temperatures in different geographic locations. Excessive heat is often accompanied by high levels of humidity , but can also be catastrophically dry. Because heat waves are not visible as other forms of severe weather, like hurricanes, tornadoes, and thunderstorms, they are one of the less known forms of extreme weather. Severely hot weather can damage populations and crops due to potential dehydration or hyperthermia , heat cramps , heat expansion , and heat stroke . Dried soils are more susceptible to erosion, decreasing lands available for agriculture . Outbreaks of wildfires can increase in frequency as dry vegetation has an increased likelihood of igniting. The evaporation of bodies of water can be devastating to marine populations, decreasing

1515-410: A leg to Cape Point , but was reduced to a 104 km (65 mi) route when authority to enter the then Cape Point Nature Reserve was refused. The organisers convinced an initially reluctant Cape Argus , a local newspaper and sponsor, to grant the event the right to use its name. The event now forms part of one of five cycling events which take place over a period of one week starting a week before

1616-532: A major gap at the Fish Hoek–Noordhoek valley. In the south much of the area is a low sandstone plateau with sand dunes. Maximum altitude is 1113 m on Table Mountain. The Cape Flats (Afrikaans: Kaapse Vlakte) is a flat, low-lying, sandy area, area to the east the Cape Peninsula, and west of the Helderberg much of which was wetland and dunes within recent history. To the north are the Tygerberg Hills and

1717-448: A number of satellite towns, suburbs and rural areas such as Atlantis , Bellville , Blouberg , Brackenfell , Durbanville , Goodwood , Gordon's Bay , Hout Bay , Khayelitsha , Kraaifontein , Kuilsrivier , Macassar , Melkbosstrand , Milnerton , Muizenberg , Noordhoek , Parow , Philadelphia , Simon's Town , Somerset West , and Strand among others. The Cape Peninsula is 52 km (30 mi) long from Mouille Point in

1818-592: A poleward extension of where the cyclones reach maximum intensity are among the consequences of human-induced climate change. Tropical cyclones use warm, moist air as their source of energy or fuel . As climate change is warming ocean temperatures , there is potentially more of this fuel available. There are plenty of anthropogenic activities that can exacerbate the effects of extreme weather events. Urban planning often amplifies urban flooding impacts, especially in areas that are at increased risk of storms due to their location and climate variability. First, increasing

1919-720: A rapid fall in temperature within a 24-hour period requiring substantially increased protection for agriculture, industry, commerce, and social activities. The precise criterion for a cold wave is determined by the rate at which the temperature falls, and the minimum to which it falls. This minimum temperature is dependent on the geographical region and time of year. Cold waves generally are capable of occurring at any geological location and are formed by large cool air masses that accumulate over certain regions, caused by movements of air streams. A cold wave can cause death and injury to livestock and wildlife. Exposure to cold mandates greater caloric intake for all animals, including humans, and if

2020-854: A short section of the N2 called Nelson Mandela Boulevard , then the M3 to Muizenberg , and then Main Road along the False Bay coast to Simon's Town and Smitswinkel Bay. The route then crosses the peninsula in a westerly direction, past the entrance to Cape of Good Hope section of the Table Mountain National Park (within which Cape Point is situated). It then heads north along the Atlantic coast through Scarborough , Kommetjie , Noordhoek , Chapman's Peak , Hout Bay over Suikerbossie Hill to Camps Bay and ends next to

2121-840: A sighting of the Cape of Good Hope. In 1510, at the Battle of Salt River , the Portuguese admiral Francisco de Almeida and sixty-four of his men were killed and his party was defeated by the "Goringhaiqua" in Dutch approximate spelling) using cattle that were specially trained to respond to whistles and shouts. The Gorinaiqua were one of the Khoikhoi clans who inhabited the area. In the late 16th century French, Danish, Dutch and English, but mainly Portuguese, ships regularly continued to stop over in Table Bay en route to

2222-401: A singular cause—there are often many atmospheric variables such as temperature, pressure, or moisture to note on top of any influences from climate change or natural variability. Aspects of our climate system have a certain level of natural variability, and extreme weather events can occur for several reasons beyond human impact, including changes in pressure or the movement of air. Areas along

2323-775: A strong wind from the south-east, known locally as the south-easter or the Cape Doctor , so called because it blows air pollution away. This wind is caused by a persistent high-pressure system over the South Atlantic to the west of Cape Town, known as the South Atlantic High , which shifts latitude seasonally, following the sun, and influencing the strength of the fronts and their northward reach. Cape Town receives about 3,100 hours of sunshine per year. Extreme weather Weather patterns can experience some variation, and so extreme weather can be attributed, at least in part, to

2424-585: Is done in this area, scientists have begun to investigate the connection between climate change and extreme weather events and what future impacts may arise. Much of this work is done through climate modeling. Climate models provide important predictions about the future characteristics of the atmosphere, oceans, and Earth using data collected in the modern day. However, while climate models are vital for studying more complex processes such as climate change or ocean acidification, they are still only approximations. Moreover, weather events are complex and cannot be tied to

2525-432: Is loss of human lives, damage to infrastructure and ecosystem destruction. For example, a global insurer Munich Re estimates that natural disasters cause more than 90 billion dollars in global direct losses in 2015. Some human activities can exacerbate the effects, for example poor urban planning , wetland destruction, and building homes along floodplains . Extreme weather describes unusual weather events that are at

2626-517: Is making some extreme weather events more frequent and more intense. This applies in particular to heat waves and cold waves. The science of extreme event attribution looks at the reasons behind extreme events. Scientists are fairly sure that climate change makes heavy rainfall events as well as drought periods more severe. Climate models indicate that rising temperatures will make extreme weather events worse worldwide. Extreme weather has serious impacts on human society and on ecosystems . There

2727-518: Is the valley of the Steenbras River, in which the Steenbras Dam was built as a water supply for Cape Town. The dam has been supplemented by several other dams around the western Cape, some of them considerably larger. This is almost entirely a conservation area, of high biodiversity. Bellville , Brackenfell , Durbanville , Kraaifontein , Goodwood and Parow are a few of the towns that make up

2828-533: The Anglo-Dutch Treaty of 1814 . The city became the capital of the newly formed Cape Colony , whose territory expanded very substantially through the 1800s, partially as a result of numerous wars with the amaXhosa on the colony's eastern frontier. In 1833 slavery was abolished in the colony freeing over 5500 slaves in the city, almost a third of the city's population at the time. The Convict Crisis of 1849, marked by substantial civil upheaval, bolstered

2929-824: The Atlantic Ocean or northeastern Pacific Ocean . A typhoon occurs in the northwestern Pacific Ocean. In the Indian Ocean and South Pacific, comparable storms are referred to as "tropical cyclones". In modern times, on average around 80 to 90 named tropical cyclones form each year around the world, over half of which develop hurricane-force winds of 65  kn (120 km/h; 75 mph) or more. Generally speaking, one event in extreme weather cannot be attributed to any one cause. However, certain system wide changes to global weather systems can lead to increased frequency or intensity of extreme weather events. Early research in extreme weather focused on statements about predicting certain events. Contemporary research focuses more on

3030-696: The Cape Colony . Until the Witwatersrand Gold Rush and the development of Johannesburg, Cape Town was the largest city in southern Africa. The metropolitan area has a long coastline on the Atlantic Ocean , which includes False Bay, and extends to the Hottentots Holland mountains to the east. The Table Mountain National Park is within the city boundaries and there are several other nature reserves and marine-protected areas within, and adjacent to,

3131-601: The Cape Floristic Region , and for landmarks such as Table Mountain and Cape Point . In 2014, Cape Town was named the best place in the world to visit by The New York Times , and was similarly ranked number one by The Daily Telegraph in both 2016 and 2023. Located on the shore of Table Bay , the City Bowl area of Cape Town is the oldest urban area in the Western Cape , with a significant cultural heritage. It

3232-695: The Cape Supergroup , of which parts of the Graafwater and Peninsula Formations remain, were uplifted between 280 and 21S million years ago, and were largely eroded away during the Mesozoic. The region was geologically stable during the Tertiary, which has led to slow denudation of the durable sandstones. Erosion rate and drainage has been influenced by fault lines and fractures, leaving remnant steep-sided massifs like Table Mountain surrounded by flatter slopes of deposits of

3333-528: The Cape Town Stadium in Green Point . In 2009 and 2010, as well as during previous years until 1999 the race had followed slightly different routes, between 104 km (65 mi) and 110 km (68 mi) in length – see the table below. The course records for conventional bicycles for the 110 km course over Chapman's Peak are: The record for the highest number of consecutive victories within

3434-544: The Fort de Goede Hoop (later replaced by the Castle of Good Hope ). The settlement grew slowly during this period, as it was hard to find adequate labour. This labour shortage prompted the local authorities to import enslaved people from Indonesia and Madagascar . Many of these people are ancestors of modern-day Cape Coloured and Cape Malay communities. Under Van Riebeeck and his successors, as VOC commanders and later governors at

3535-497: The National Oceanic and Atmospheric Administration (NOAA) of the U.S. government predicted that, over the 21st Century, the frequency of tropical storms and Atlantic hurricanes would decline by 25 percent while their maximum intensity would rise by 5 percent. Climate change affects tropical cyclones in a variety of ways: an intensification of rainfall and wind speed, an increase in the frequency of very intense storms and

3636-521: The Northern Suburbs of Cape Town. In current popular culture these areas are often referred to as being beyond the " boerewors curtain," a play on the term " iron curtain ." UNESCO declared Robben Island in the Western Cape a World Heritage Site in 1999. Robben Island is located in Table Bay, some 6 km (3.7 mi) west of Bloubergstrand, a coastal suburb north of Cape Town, and stands some 30m above sea level. Robben Island has been used as

3737-595: The Southern Suburbs , close to the mountains, rainfall is significantly higher and averages closer to 1,000 mm (39.4 in). Summer, which lasts from December to March, is warm and dry with an average maximum of 26 °C (79 °F) and minimum of 16 °C (61 °F). The region can get uncomfortably hot when the Berg Wind , meaning "mountain wind", blows from the Karoo interior. Spring and summer generally feature

3838-615: The Table Mountain group sandstones that were deposited on the eroded surface of the granite and Malmesbury series basement about 450 million years ago. The sand, silt and mud deposits were lithified by pressure and then folded during the Cape Orogeny to form the Cape Fold Belt , which extends in an arc along the western and southern coasts. The present landscape is due to prolonged erosion having carved out deep valleys, removing parts of

3939-563: The 1920s, according to the International Disaster Database, even as the total human population on Earth quadrupled, and temperatures rose 1.3 °C. In the 1920s, 5.4 million people died from natural disasters while in the 2010s, just 400,000 did. The most dramatic and rapid declines in deaths from extreme weather events have taken place in south Asia. Where a tropical cyclone in 1991 in Bangladesh killed 135,000 people, and

4040-562: The 19th century came to an end, the economic and political dominance of Cape Town in the Southern Africa region during the 19th century started to give way to the dominance of Johannesburg and Pretoria in the 20th century. In 1910, Britain established the Union of South Africa , which unified the Cape Colony with the two defeated Boer Republics and the British colony of Natal . Cape Town became

4141-547: The Arctic . However, conclusions that link climate change to cold waves are considered to still be controversial. The JRC PESETA IV project concluded in 2020 that overall climate change will result in a decline in the intensity and frequency of extreme cold spells, with milder winters reducing fatalities from extreme cold, even if individual cold extreme weather may sometimes be caused by changes due to climate change and possibly even become more frequent in some regions. According to

4242-491: The Atlantic Ocean with significant precipitation and strong north-westerly winds. Winter months in the city average a maximum of 18 °C (64 °F) and minimum of 8.5 °C (47 °F). Winters are snow and frost free, except on Table Mountain and on other mountain peaks, where light accumulation of snow and frost can sometimes occur. Total annual rainfall in the city averages 515 mm (20.3 in) although in

4343-574: The Cape was considered a " Coloured labour preference area", to the exclusion of " Bantus ", i.e. Black Africans. The implementation of this policy was widely opposed by trade unions, civil society and opposition parties. It is notable that this policy was not advocated for by any Coloured political group, and its implementation was a unilateral decision by the apartheid government. During the student-led Soweto Uprising of June 1976, school students from Langa , Gugulethu and Nyanga in Cape Town reacted to

4444-464: The Cape, a wide range of agricultural plants were introduced to the Cape. Some of these, including grapes, cereals, ground nuts, potatoes, apples and citrus, had a large and lasting influence on the societies and economies of the region. With the Dutch Republic being transformed into Revolutionary France 's vassal Batavian Republic , Great Britain moved to take control of Dutch colonies, including

4545-615: The Cycle Tour and culminating in the Cycle Tour. The other events include: Between 2000 and 2003, the race followed an alternative route due to the closure of Chapman's Peak Drive, with a return trip via Ou Kaapse Weg and the Blue Route. The race has been stopped three times due to extreme weather , although in the first two cases many competitors had completed the race before the stoppage, and once significantly shortened due to fire. It has been cancelled once: Key information regarding each of

4646-582: The Indies. They traded tobacco, copper, and iron with the Khoikhoi clans of the region in exchange for fresh meat and other essential travelling provisions. In 1652, Jan van Riebeeck and other employees of the United East India Company ( Dutch : Verenigde Oost-indische Compagnie , VOC) were sent to the Cape Colony to establish a way-station for ships travelling to the Dutch East Indies , and

4747-588: The Stellenbosch district. The Helderberg area of Greater Cape Town, previously known as the "Hottentots-Holland" area, is mostly residential, but also a wine-producing area east of the Cape Flats, west of the Hottentots Holland mountain range and south of the Helderberg mountain, from which it gets its current name. The Helderberg consists of the previous municipalities of Somerset West, Strand, Gordons Bay and

4848-566: The Stellenbosch granite pluton. The region includes the entire catchment of the Lourens and Sir Lowry's rivers, separated by the Schapenberg hill, and a small part of the catchment of the Eerste River to the west. The Helderberg is ecologically highly diverse, rivaling the Cape Peninsula, and has its own endemic ecoregions and several conservation areas. To the east of the Hottentots Holland mountains

4949-630: The Western Cape province. The official boundaries of the city proper extend between the City Bowl and the Atlantic Seaboard to the east and the Southern Suburbs to the south. The City of Cape Town , the metropolitan municipality that takes its name from the city covers the Greater Cape Town metropolitan area , known as the Cape Metropole, extending beyond the city proper itself to include

5050-572: The amount of impervious surfaces, such as sidewalks, roads, and roofs, means that less of the water from incoming storms is absorbed by the land. The destruction of wetlands, which act as a natural reservoir by absorbing water, can intensify the impact of floods and extreme precipitation. This can happen both inland and at the coast. However, wetland destruction along the coast can mean decreasing an area's natural 'cushion,' thus allowing storm surges and flood waters to reach farther inland during hurricanes or cyclones. Building homes below sea level or along

5151-496: The attribution of causes to trends in events. In particular the field is focusing on climate change alongside other causal factors for these events. A 2016 report from the National Academies of Sciences, Engineering, and Medicine , recommended investing in improved shared practices across the field working on attribution research, improving the connection between research outcomes and weather forecasting.

The first democratic election , was held four years later, on 27 April 1994. Nobel Square in the Victoria & Alfred Waterfront features statues of South Africa's four Nobel Peace Prize winners: Albert Luthuli , Desmond Tutu , F. W. de Klerk and Nelson Mandela . Cape Town has undergone significant changes in

Of those, 21 were in the Western Cape. The city's economy has diversified, with growth in sectors such as finance, real estate, and tourism. The establishment of the City Centre Improvement District (CCID) has been particularly successful in revitalizing

5454-556: The city center, bringing businesses and people back into the area. This initiative has transformed public spaces such as Greenmarket Square , Company's Garden , and St George's Mall, attracting both locals and tourists. In 2014, Cape Town was named World Design Capital of the Year. Cape Town was voted the best tourist destination in Africa at the 2023 World Travel Awards in Dubai and continues to be

5555-509: The city centre. The legacy of Apartheid means Cape Town remains one of the most racially segregated cities in South Africa. Many Black South Africans continue to live in informal settlements with limited access to basic services such as healthcare, education, and sanitation. The unemployment rate remains high at 23% (though nearly 10 points lower than the nationwide average), particularly among historically disadvantaged groups, and economic opportunities are unevenly distributed. Cape Town faced

5656-577: The city, protecting the diverse terrestrial and marine natural environment. The earliest known remnants of human occupation in the region were found at Peers Cave in Fish Hoek and have been dated to between 15,000 and 12,000 years old. Various Khoikhoi groups notably the Gorinaiqua lived on these lands for thousands of years. Khoikhoi communities were some of the wealthiest groups in Africa and their lands and cattles would go on to build colonial Cape Town and

5757-560: The coast or located in tropical regions are more likely to experience storms with heavy precipitation than temperate regions, although such events can occur. The atmosphere is a complex and dynamic system, influenced by several factors such as the natural tilt and orbit of the Earth, the absorption or reflection of solar radiation, the movement of air masses, and the water cycle . Due to this, weather patterns can experience some variation, and so extreme weather can be attributed, at least in part, to

5858-619: The colonial possessions of the VOC. Britain captured Cape Town in 1795 , but it was returned to the Dutch by treaty in 1803. British forces occupied the Cape again in 1806 following the Battle of Blaauwberg when the Batavian Republic allied with Britain's rival, France, during the Napoleonic Wars . Following the conclusion of the war Cape Town was permanently ceded to the United Kingdom in

Support for parties "which have formally adopted Cape independence" was around 5% in the 2021 municipal elections . Cape Town is located at latitude 33.55° S (approximately the same as Sydney and Buenos Aires and equivalent to Casablanca and Los Angeles in

At this time the drainage outlets lay between Rocky Bank Cape Point to the west, and between Rocky Bank and Hangklip Ridge to the east, with the watershed roughly along the line of the contact zone east of Seal Island and Whittle Rock. Cape Town has a warm summer Mediterranean climate ( Köppen : Csb ), with mild, moderately wet winters and dry, warm summers. Winter, which lasts from June to September, may see large cold fronts entering for limited periods from

The landscape is dominated by sandstone plateaux and ridges, which generally drop steeply at their margins to the surrounding debris slopes, interrupted by

6363-418: The extremes of the historical distribution for a given area. The IPCC Sixth Assessment Report defines an extreme weather event as follows: "An event that is rare at a particular place and time of year. Definitions of 'rare' vary, but an extreme weather event would normally be as rare as or rarer than the 10th or 90th percentile of a probability density function estimated from observations." In comparison,

6464-785: The face of record breaking extreme weather events, climate change adaptation efforts fall short while economists are confronted with inflation, the cost-of-living crisis , and economic uncertainty . In 2011 the IPCC estimated, that annual losses have ranged since 1980 from a few billion to above US$ 200 billion, with the highest economic losses occurring in 2005, the year of Hurricane Katrina . The global weather-related disaster losses, such as loss of human lives, cultural heritage, and ecosystem services , are difficult to value and monetize, and thus they are poorly reflected in estimates of losses. The World Economic Forum Global Risks Perception Survey 2023-2024 (GRPS) found that 66 percent of respondents selected extreme weather as top risk. The survey

6565-631: The future. This is where climate models are useful, for they can provide simulations of how the atmosphere may behave over time and what steps need to be taken in the present day to mitigate any negative changes. The increasing probability of record week-long heat extremes occurrence depends on warming rate, rather than global warming level. Some researchers attribute increases in extreme weather occurrences to more reliable reporting systems. A difference in what qualifies as 'extreme weather' in varying climate systems could also be argued. Over or under reporting of casualties or losses can lead to inaccuracy in

6666-423: The growing season in mid-latitude zones can kill plants during the early and most vulnerable stages of growth. This results in crop failure as plants are killed before they can be harvested economically. Such cold waves have caused famines . Cold waves can also cause soil particles to harden and freeze, making it harder for plants and vegetation to grow within these areas. One extreme was the so-called Year Without

6767-429: The impact of extreme weather. However, the UN reports show that, although some countries have experienced greater effects, there have been increases in extreme weather events on all continents. Current evidence and climate models show that an increasing global temperature will intensify extreme weather events around the globe, thereby amplifying human loss, damages and economic costs, and ecosystem destruction. In 2020,

6868-415: The large amounts of impervious surfaces in cities, can have devastating impacts. Impervious surfaces also absorb energy from the sun and warm the atmosphere, causing drastic increases in temperatures in urban areas. This, along with pollution and heat released from cars and other anthropogenic sources, contributes to urban heat islands. The effects of extreme weather includes, but are not limited to: In

6969-418: The larger share and decreasing and heat-related ones making up ~0.91 % and increasing. Climate change has led to an increase in the frequency and/or intensity of certain types of extreme weather.

The Cycle Tour formed the last leg of the Giro del Capo , a multi-stage race for professional and leading registered riders which

7171-407: The legislative capital of the Union, and later of the Republic of South Africa . By the time of the 1936 census , Johannesburg had overtaken Cape Town as the largest city in the country. In 1945 the expansion of the Cape Town foreshore was completed adding an additional 194 ha (480 acres) to the City Bowl area to the city centre. Prior to the mid-twentieth century, Cape Town was one of

7272-465: The most important tourist destination in the country. Cape Town has been named the best travel city in the world every year since 2013 in the Telegraph Travel Awards. The legacy of apartheid's spatial planning is still evident, with significant disparities between affluent areas and impoverished townships . 60% of the city's population live in townships and informal settlements far from

7373-751: The most racially integrated cities in South Africa. In the 1948 national elections , the National Party won on a platform of apartheid (racial segregation) under the slogan of " swart gevaar " (Afrikaans for "black danger"). This led to the erosion and eventual abolition of the Cape's multiracial franchise . In 1950, the apartheid government first introduced the Group Areas Act , which classified and segregated urban areas according to race. Formerly multi-racial suburbs of Cape Town were either purged of residents deemed unlawful by apartheid legislation, or demolished. The most infamous example of this in Cape Town

7474-486: The mountain. To the immediate south of the city, the Cape Peninsula is a scenic mountainous spine jutting 40 km (25 mi) southward into the Atlantic Ocean and terminating at Cape Point . There are over 70 peaks above 300 m (980 ft) within Cape Town's official metropolitan limits . Many of the city's suburbs lie on the large plain called the Cape Flats , which extends over 50 km (30 mi) to

7575-582: The natural climate variability that exists on Earth. Climatic phenomena such as the El Niño-Southern Oscillation (ENSO) or the North Atlantic Oscillation (NAO) impact weather patterns in specific regions of the world, influencing temperature and precipitation. The record-breaking extreme weather events that have been catalogued throughout the past two hundred years most likely arise when climate patterns like ENSO or NAO work "in

7676-466: The natural climate variability that exists on Earth. For example, the El Niño-Southern Oscillation (ENSO) or the North Atlantic Oscillation (NAO) are climate phenomena that impact weather patterns worldwide. Generally speaking, one event in extreme weather cannot be attributed to any one single cause. However, certain system wide changes to global weather systems can lead to increased frequency or intensity of extreme weather events. Climate change

Table Mountain , with its near vertical cliffs and flat-topped summit over 1,000 m (3,300 ft) high, and with Devil's Peak and Lion's Head on either side, together form a dramatic mountainous backdrop enclosing the central area of Cape Town, the so-called City Bowl . A thin strip of cloud, known colloquially as the "tablecloth" ("Karos" in Afrikaans ), sometimes forms on top of

8080-450: The once continuous Table Mountain Group sandstone cover from over the Cape Flats and False Bay, and leaving high residual mountain ridges. At times the sea covered the Cape Flats and Noordhoek valley and the Cape Peninsula was then a group of islands. During glacial periods the sea level dropped to expose the bottom of False Bay to weathering and erosion, with the last major regression leaving

8181-638: The population. It has been estimated that extra pollution during the hot summer of 2006 in the UK, cost 460 lives. The European heat waves from summer 2003 are estimated to have caused 30,000 excess deaths, due to heat stress and air pollution . Over 200 U.S cities have registered new record high temperatures. The worst heat wave in the US occurred in 1936 and killed more than 5000 people directly. The worst heat wave in Australia occurred in 1938–39 and killed 438. The second worst

8282-424: The push for self-governance in the Cape. With expansion came calls for greater independence from the UK, with the Cape attaining its own parliament (1854) and a locally accountable Prime Minister (1872). Suffrage was established according to the non-racial Cape Qualified Franchise . During the 1850s and 1860s, additional plant species were introduced from Australia by the British authorities. Notably rooikrans

It was later renamed by John II of Portugal as " Cape of Good Hope " ( Cabo da Boa Esperança ) because of the great optimism engendered by the opening of a sea route to the Indian subcontinent and East Indies . In 1497, Portuguese explorer Vasco da Gama recorded

8585-559: The same direction as human‐induced warming." Some studies assert a connection between rapidly warming arctic temperatures and thus a vanishing cryosphere to extreme weather in mid-latitudes. In a study published in Nature in 2019, scientists used several simulations to determine that the melting of ice sheets in Greenland and Antarctica could affect overall sea level and sea temperature. Other models have shown that modern temperature rise and

Famous prisoners include activist, lawyer and future president Nelson Mandela who served 18 of his 27 years of imprisonment on the island, as well as two other future presidents, Kgalema Motlanthe and Jacob Zuma . In one of the most famous moments marking the end of apartheid, Nelson Mandela made his first public speech since his imprisonment, from

8787-399: The size of the habitats available as well as the amount of nutrition present within the waters. Livestock and other animal populations may decline as well. During excessive heat, plants shut their leaf pores ( stomata ), a protective mechanism to conserve water but also curtails plants' absorption capabilities. This leaves more pollution and ozone in the air, which leads to higher mortality in

8888-558: The south, the Cape Flats , the Helderberg basin and part of the Steenbras catchment area to the east, and the Tygerberg hills, Blouberg and other areas to the north. Robben Island in Table Bay is also part of Cape Town. It is bounded by the Atlantic Ocean to the west, and False Bay to the south. To the north and east, the extent is demarcated by boundaries of neighbouring municipalities within

8989-758: The subsequent addition of meltwater to the ocean could lead to a disruption of the thermohaline circulation, which is responsible for the movement of seawater and distribution of heat around the globe. A collapse of this circulation in the northern hemisphere could lead to an increase in extreme temperatures in Europe, as well as more frequent storms by throwing off natural climate variability and conditions. Thus, as increasing temperatures cause glaciers to melt, mid-latitudes could experience shifts in weather patterns or temperatures. There were around 6,681 climate-related events reported during 2000-2019, compared to 3,656 climate-related events reported during 1980–1999. In this report,

9090-418: The term severe weather is any aspect of the weather that poses risks to life, property or requires the intervention of authorities. Severe weather is thus a particular type of extreme weather. Definitions of extreme weather vary in different parts of the community, changing the outcomes of research from those fields. Heat waves are periods of abnormally high temperatures and heat index . Definitions of

He is also the oldest man to have ridden the Argus for the first time, which he did in 2004 when he was 84 years old. The oldest woman to complete the race is Mary Warner (80 years old at

9393-431: The water molecules having increased kinetic energy, and precipitation occurs at a greater rate because more molecules have the critical speed needed to fall as rain drops. A shift in rainfall patterns can lead to greater amounts of precipitation in one area while another experiences much hotter, drier conditions, which can lead to drought. This is because an increase in temperatures also lead to an increase in evaporation at

Cape Town outgrew its original purpose as the first European outpost at the Castle of Good Hope , becoming the economic and cultural hub of

9898-399: Was in 1896. Power outages can also occur within areas experiencing heat waves due to the increased demand for electricity (i.e. air conditioning use). The urban heat island effect can increase temperatures, particularly overnight. A cold wave is a weather phenomenon that is distinguished by a cooling of the air. Specifically, as used by the U.S. National Weather Service , a cold wave is
