The mountain is part of a ski area and its summit is easily accessible from Bretaye with the Bex–Villars–Bretaye railway . A ski-lift leads to a secondary summit (1,987 m). Mountain A mountain is an elevated portion of the Earth's crust , generally with steep sides that show significant exposed bedrock . Although definitions vary,

136-652: A Declaration on the Human Environment ( Stockholm Declaration ) and the establishment of an environmental management body, which was later named the United Nations Environment Program (UNEP). UNEP was established by General Assembly Resolution 2997. Headquarters were established in Nairobi , Kenya, with a staff of 300, including 100 professionals in a variety of fields, and with a five-year fund of more than US$ 100 million. At

204-428: A biotemperature below 1.5 °C (34.7 °F). Mountain environments are particularly sensitive to anthropogenic climate change and are currently undergoing alterations unprecedented in last 10,000 years. The effect of global warming on mountain regions (relative to lowlands) is still an active area of study. Observational studies show that highlands are warming faster than nearby lowlands, but when compared globally,

272-647: A book with the Parliament of the World's Religions Climate Action Program entitled, "Faith for Earth: A Call for Action." The book serves as an educational resource for students, teachers, and leaders across the world and highlights the role that faith-based organizations can play in addressing critical environmental issues. UN assigns specific years to topics to raise awareness and engagement. The following years pertain to environmental topics: See international observance and list of environmental dates . Following

340-666: A joint statement with the United Nations University predicting that "50 million people could become environmental refugees by 2010, fleeing the effects of climate change ". This was reinforced in 2008, by Srgjan Kerim, President of the UN General Assembly, who estimated that there would be between 50 million and 200 million environmental migrants by 2010. In 2008, UNEP made a series of statements that glaciers are shrinking at record rates and many could disappear within decades. Scientists measuring

408-692: A member of the United Nations Development Group , UNEP aims to help the world meet the 17 Sustainable Development Goals . UNEP hosts the secretariats of several multilateral environmental agreements and research bodies, including The Convention on Biological Diversity (CBD), The Minamata Convention on Mercury , The Basel , Rotterdam and Stockholm Conventions, The Convention on Migratory Species and The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), among others. In 1988,

476-464: A mountain is roughly equivalent to moving 80 kilometres (45 miles or 0.75° of latitude ) towards the nearest pole. This relationship is only approximate, however, since local factors such as proximity to oceans (such as the Arctic Ocean) can drastically modify the climate. As the altitude increases, the main form of precipitation becomes snow and the winds increase. The effect of

544-481: A mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill , typically rising at least 300 metres (980  ft ) above the surrounding land. A few mountains are isolated summits , but most occur in mountain ranges . Mountains are formed through tectonic forces , erosion , or volcanism , which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through

612-648: A significant role in religion. There are for example a number of sacred mountains within Greece such as Mount Olympus which was held to be the home of the gods. In Japanese culture, the 3,776.24 m (12,389.2 ft) volcano of Mount Fuji is also held to be sacred with tens of thousands of Japanese ascending it each year. Mount Kailash , in the Tibet Autonomous Region of China, is considered to be sacred in four religions: Hinduism, Bon , Buddhism, and Jainism . In Ireland, pilgrimages are made up

680-594: A universal member system (all UN member states). (UNEA, UN Environment Assembly) It was implemented once in 2014. The European Investment Bank and the United Nations Environment Programme created the Renewable Energy Performance Platform (REPP) in 2015 to assist a United Nations project dubbed Sustainable Energy for All. Renewable Energy Performance Platform was established with $ 67 million from

748-471: A whole, 24% of the Earth's land mass is mountainous. There are three main types of mountains: volcanic , fold , and block . All three types are formed from plate tectonics : when portions of the Earth's crust move, crumple, and dive. Compressional forces, isostatic uplift and intrusion of igneous matter forces surface rock upward, creating a landform higher than the surrounding features. The height of

816-452: Is El Alto , Bolivia, at 4,150 metres (13,620 ft), which has a highly diverse service and manufacturing economy and a population of nearly 1 million. Traditional mountain societies rely on agriculture, with higher risk of crop failure than at lower elevations. Minerals often occur in mountains, with mining being an important component of the economics of some mountain-based societies. More recently, tourism has become more important to

884-571: Is Mount Everest in the Himalayas of Asia , whose summit is 8,850 m (29,035 ft) above mean sea level. The highest known mountain on any planet in the Solar System is Olympus Mons on Mars at 21,171 m (69,459 ft). The tallest mountain including submarine terrain is Mauna Kea in Hawaii from its underwater base at 9,330 m (30,610 ft) and some scientists consider it to be

952-478: Is a poor conductor of heat, so a parcel of air will rise and fall without exchanging heat. This is known as an adiabatic process , which has a characteristic pressure-temperature dependence. As the pressure gets lower, the temperature decreases. The rate of decrease of temperature with elevation is known as the adiabatic lapse rate , which is approximately 9.8 °C per kilometre (or 5.4 °F (3.0 °C) per 1000 feet) of altitude. The presence of water in

1020-419: Is a set of outdoor activities that involves ascending mountains . Mountaineering-related activities include traditional outdoor climbing , skiing , and traversing via ferratas that have become sports in their own right. Indoor climbing , sport climbing , and bouldering are also considered variants of mountaineering by some, but are part of a wide group of mountain sports . Mountains often play

1088-556: Is not enough oxygen to support human life. This is sometimes referred to as the " death zone ". The summits of Mount Everest and K2 are in the death zone. Mountains are generally less preferable for human habitation than lowlands, because of harsh weather and little level ground suitable for agriculture . While 7% of the land area of Earth is above 2,500 metres (8,200 ft), only 140 million people live above that altitude and only 20-30 million people above 3,000 metres (9,800 ft) elevation. About half of mountain dwellers live in

Established in 1974, this is the world's only legal programme for the purpose of protecting

1224-457: Is the highest mountain on Earth, at 8,848 metres (29,029 ft). There are at least 100 mountains with heights of over 7,200 metres (23,622 ft) above sea level, all of which are located in central and southern Asia. The highest mountains above sea level are generally not the highest above the surrounding terrain. There is no precise definition of surrounding base, but Denali , Mount Kilimanjaro and Nanga Parbat are possible candidates for

1292-525: Is the largest mountain on Earth in terms of base area (about 2,000 sq mi or 5,200 km ) and volume (about 18,000 cu mi or 75,000 km ). Mount Kilimanjaro is the largest non-shield volcano in terms of both base area (245 sq mi or 635 km ) and volume (1,150 cu mi or 4,793 km ). Mount Logan is the largest non-volcanic mountain in base area (120 sq mi or 311 km ). The highest mountains above sea level are also not those with peaks farthest from

1360-561: Is the solar loan programme sponsored by UNEP that helped 100,000 people finance solar power systems in India . Success in India's solar programme has led to similar projects in other parts of the developing world, including Tunisia , Morocco , Indonesia and Mexico . In 2001, UNEP alerted about the destruction of the Marshlands when it released satellite images showing that 90 percent of

1428-526: The Andes , Central Asia, and Africa. With limited access to infrastructure, only a handful of human communities exist above 4,000 metres (13,000 ft) of elevation. Many are small and have heavily specialized economies, often relying on industries such as agriculture, mining, and tourism. An example of such a specialized town is La Rinconada, Peru , a gold-mining town and the highest elevation human habitation at 5,100 metres (16,700 ft). A counterexample

1496-649: The Basin and Range Province of Western North America. These areas often occur when the regional stress is extensional and the crust is thinned. During and following uplift, mountains are subjected to the agents of erosion (water, wind, ice, and gravity) which gradually wear the uplifted area down. Erosion causes the surface of mountains to be younger than the rocks that form the mountains themselves. Glacial processes produce characteristic landforms, such as pyramidal peaks , knife-edge arêtes , and bowl-shaped cirques that can contain lakes. Plateau mountains, such as

1564-468: The Catskills , are formed from the erosion of an uplifted plateau. Climate in the mountains becomes colder at high elevations , due to an interaction between radiation and convection. Sunlight in the visible spectrum hits the ground and heats it. The ground then heats the air at the surface. If radiation were the only way to transfer heat from the ground to space, the greenhouse effect of gases in

1632-716: The United Kingdom 's International Climate Finance initiative, administered by the Department for Business, Energy and Industrial Strategy , in 2015, and $ 128 million in 2018. REPP was established with a five-year goal of improving energy access for at least two million people in Sub-Saharan Africa. It has so far invested around $ 45 million to renewable energy projects in 13 countries in Sub-Saharan Africa . Solar power and hydropower are among

1700-650: The World Conservation Monitoring Centre , based in Cambridge and sponsored by IUCN , became part of UNEP. In December 1972, the UN General Assembly unanimously elected Maurice Strong to be the first head of UN Environment. He was also secretary-general of both the 1972 United Nations Conference on the Human Environment and the Earth Summit (1992). The position was then held for 17 years (1975–1992) by Mostafa Kamal Tolba , who

1768-903: The World Meteorological Organization and UNEP established the Intergovernmental Panel on Climate Change (IPCC). UNEP is also one of several Implementing Agencies for the Global Environment Facility (GEF) and the Multilateral Fund for the Implementation of the Montreal Protocol . UNEP sometimes uses the alternative name UN Environment. The headquarters of the agency is in Nairobi, Kenya. In

1836-443: The 1970s, the need for environmental governance at a global level was not universally accepted, particularly by developing nations. Some argued that environmental concerns were not a priority for nations in poverty. The leadership of Canadian diplomat Maurice Strong convinced many of the developing nations' governments that they needed to prioritize this issue. In the words of Nigerian professor Adebayo Adedeji : "Mr. Strong, through

1904-409: The 1987 Montreal Protocol for limiting emissions of gases blamed for thinning the planet's protective ozone layer, and the 2017 Minamata Convention , a treaty to limit toxic mercury. UNEP has sponsored the development of solar loan programmes, with attractive return rates, to buffer the initial deployment costs and entice consumers to consider and purchase solar PV systems . The most famous example

1972-694: The 2007 publication of the Intergovernmental Panel on Climate Change Fourth Assessment Report , the Paris Call for Action , presented by French president Jacques Chirac and supported by 46 countries, called for the UNEP to be replaced by a new and more powerful "United Nations Environment Organization", to be modeled on the World Health Organization . The 46 countries included the European Union nations, but notably did not include

2040-621: The 952 metres (3,123 ft) Mount Brandon by Irish Catholics . The Himalayan peak of Nanda Devi is associated with the Hindu goddesses Nanda and Sunanda; it has been off-limits to climbers since 1983. Mount Ararat is a sacred mountain, as it is believed to be the landing place of Noah's Ark . In Europe and especially in the Alps , summit crosses are often erected on the tops of prominent mountains. Heights of mountains are typically measured above sea level . Using this metric, Mount Everest

2108-698: The International Environmental Education Programme (1975–1995), which set out a vision for, and gave practical guidance on how to mobilize education for environmental awareness. In 1976 UNESCO launched an environmental education newsletter Connect as the official organ of the UNESCO-UNEP International Environmental Education Programme (IEEP). Until 2007 it served as a clearinghouse to exchange information on environmental education in general and to promote

2176-455: The US. Fold mountains occur when two plates collide: shortening occurs along thrust faults and the crust is overthickened. Since the less dense continental crust "floats" on the denser mantle rocks beneath, the weight of any crustal material forced upward to form hills, plateaus or mountains must be balanced by the buoyancy force of a much greater volume forced downward into the mantle. Thus

2244-694: The United States, Saudi Arabia, Russia, and China, the top four emitters of greenhouse gases . In December 2012, following the Rio+20 Summit, a decision by the General Assembly of the United Nations to "strengthen and upgrade" the UNEP and establish universal membership of its governing body was confirmed. In other words, it was reorganized by applying the existing executive member system (58 member states) from 1973 to 2013 to

2312-622: The action of weathering , through slumping and other forms of mass wasting , as well as through erosion by rivers and glaciers . High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and climate, mountains tend to be used less for agriculture and more for resource extraction, such as mining and logging , along with recreation, such as mountain climbing and skiing . The highest mountain on Earth

2380-581: The adjacent elevation, is impressive or notable." Whether a landform is called a mountain may depend on local usage. John Whittow's Dictionary of Physical Geography states "Some authorities regard eminences above 600 metres (1,969 ft) as mountains, those below being referred to as hills." In the United Kingdom and the Republic of Ireland, a mountain is usually defined as any summit at least 2,000 feet (610 m) high, which accords with

2448-450: The aims and activities of the IEEP in particular, as well as being a network for institutions and individuals interested and active in environment education. Climate change In 1989, UNEP published a statement predicting that "entire nations could be wiped off the face of the Earth by sea level rise if the global warming trend is not reversed by the year 2000". In 2005, UNEP issued

2516-553: The atmosphere complicates the process of convection. Water vapor contains latent heat of vaporization . As air rises and cools, it eventually becomes saturated and cannot hold its quantity of water vapor. The water vapor condenses to form clouds and releases heat, which changes the lapse rate from the dry adiabatic lapse rate to the moist adiabatic lapse rate (5.5 °C per kilometre or 3 °F (1.7 °C) per 1000 feet) The actual lapse rate can vary by altitude and by location. Therefore, moving up 100 m (330 ft) on

2584-429: The atmosphere would keep the ground at roughly 333 K (60 °C; 140 °F), and the temperature would decay exponentially with height. However, when air is hot, it tends to expand, which lowers its density. Thus, hot air tends to rise and transfer heat upward. This is the process of convection . Convection comes to equilibrium when a parcel of air at a given altitude has the same density as its surroundings. Air

2652-528: The centre of the Earth, because the figure of the Earth is not spherical. Sea level closer to the equator is several miles farther from the centre of the Earth. The summit of Chimborazo , Ecuador's tallest mountain, is usually considered to be the farthest point from the Earth's centre, although the southern summit of Peru's tallest mountain, Huascarán , is another contender. Both have elevations above sea level more than 2 kilometres (6,600 ft) less than that of Everest. UN Environmental Programme As

2720-459: The climate on the ecology at an elevation can be largely captured through a combination of amount of precipitation, and the biotemperature , as described by Leslie Holdridge in 1947. Biotemperature is the mean temperature; all temperatures below 0 °C (32 °F) are considered to be 0 °C. When the temperature is below 0 °C, plants are dormant, so the exact temperature is unimportant. The peaks of mountains with permanent snow can have

2788-534: The conditions above and below a particular zone will be inhospitable and thus constrain their movements or dispersal . These isolated ecological systems are known as sky islands . Altitudinal zones tend to follow a typical pattern. At the highest elevations, trees cannot grow, and whatever life may be present will be of the alpine type, resembling tundra . Just below the tree line , one may find subalpine forests of needleleaf trees, which can withstand cold, dry conditions. Below that, montane forests grow. In

2856-476: The continental crust is normally much thicker under mountains, compared to lower lying areas. Rock can fold either symmetrically or asymmetrically. The upfolds are anticlines and the downfolds are synclines : in asymmetric folding there may also be recumbent and overturned folds. The Balkan Mountains and the Jura Mountains are examples of fold mountains. Block mountains are caused by faults in

2924-513: The core source of UNEP's programs. Between 1974 and 1986 UNEP produced more than 200 technical guidelines or manuals on environment including forest and water management, pest control , pollution monitoring, the relationship between chemical use and health, and management of industry. The location of the headquarters proved to be a major controversy, with developed countries preferring Geneva , where several other UN offices are based, while developing countries preferred Nairobi, as that would be

2992-513: The crust: a plane where rocks have moved past each other. When rocks on one side of a fault rise relative to the other, it can form a mountain. The uplifted blocks are block mountains or horsts . The intervening dropped blocks are termed graben : these can be small or form extensive rift valley systems. This kind of landscape can be seen in East Africa , the Vosges and Rhine valley, and

3060-548: The definition since the 1970s. Any similar landform lower than this height was considered a hill. However, today, the United States Geological Survey concludes that these terms do not have technical definitions in the US. The UN Environmental Programme 's definition of "mountainous environment" includes any of the following: Using these definitions, mountains cover 33% of Eurasia, 19% of South America, 24% of North America, and 14% of Africa. As

3128-460: The dry season and in semiarid areas such as in central Asia. Alpine ecosystems can be particularly climatically sensitive. Many mid-latitude mountains act as cold climate refugia, with the ecosystems occupying small environmental niches. As well as the direct influence that the change in climate can have on an ecosystem, there is also the indirect one on the soils from changes in stability and soil development. The colder climate on mountains affects

3196-523: The economies of mountain communities, with developments focused around attractions such as national parks and ski resorts . Approximately 80% of mountain people live below the poverty line. Most of the world's rivers are fed from mountain sources, with snow acting as a storage mechanism for downstream users. More than half of humanity depends on mountains for water. In geopolitics , mountains are often seen as natural boundaries between polities. Mountaineering , mountain climbing, or alpinism

3264-428: The effect disappears. Precipitation in highland areas is not increasing as quickly as in lowland areas. Climate modeling give mixed signals about whether a particular highland area will have increased or decreased precipitation. Climate change has started to affect the physical and ecological systems of mountains. In recent decades mountain ice caps and glaciers have experienced accelerating ice loss. The melting of

3332-623: The energy methods used in the projects. In September 2018, a series of allegations were made against the executive director of the UNEP, Eric Solheim, at that time, including excessive number of days spent outside the headquarters in Nairobi, Kenya. As a result, Eric Solheim resigned. Several donor countries withdrew their donation in the aftermath of the allegation, including the Dutch government who announced it would withhold $ 8 million in funding to UNEP until nepotism issues were resolved. Sweden and Denmark stopped funding as well. A spokesman for

3400-444: The environmental field. The Global 500 Roll of Honour was initiated in 1987 and ended in 2003. Its 2005 successor, Champions of the Earth , and a similar award, Young Champions of the Earth , are given annually to entrepreneurs, scientists, policy leaders, upcoming talent, individuals and organizations who make significant positive impacts on resources and the environment in their areas. UNEP has registered several successes, such as

3468-433: The feature makes it either a hill or, if higher and steeper, a mountain. Major mountains tend to occur in long linear arcs, indicating tectonic plate boundaries and activity. Volcanoes are formed when a plate is pushed below another plate , or at a mid-ocean ridge or hotspot . At a depth of around 100 km (60 mi), melting occurs in rock above the slab (due to the addition of water), and forms magma that reaches

At this international conference 250 politicians and representatives of non-government organizations discussed future road transportation under the motto of "Sustainable Mobility–the Post-2012 CO 2 Agenda". Circular economy UNEP

3604-478: The first international organization headquartered in the Global South . At first, Mexico City , New Delhi , and Cairo were also competing to be the headquarters, but they pulled out to support Nairobi. Many of the developing countries were "not particularly supportive of creating a new formal institution for environmental governance", but supported its creation as an act of "Southern solidarity". In 2000,

3672-498: The glaciers, permafrost and snow has caused underlying surfaces to become increasingly unstable. Landslip hazards have increased in both number and magnitude due to climate change. Patterns of river discharge will also be significantly affected by climate change, which in turn will have significant impacts on communities that rely on water fed from alpine sources. Nearly half of mountain areas provide essential or supportive water resources for mainly urban populations, in particular during

3740-426: The health of almost 30 glaciers around the world found that ice loss reached record levels in 2006. On average, the studied glaciers shrank by 4.9 feet in 2006. Norway 's Breidalblikkbrea glacier shrank 10.2 feet in 2006. Glaciers lost an average of about a foot of ice a year between 1980 and 1999, but since the turn of the millennium the average loss has increased to about 20 inches. Electric vehicles At

3808-586: The marsh had been lost. The UNEP "support for environmental management of the Iraqi Marshland" began in 2004, to manage the marshland area in an environmentally sound manner. UNEP has a programme for young people known as Tunza. Within this programme are other projects like the AEO for Youth . UNEP uses its position to raise awareness for a range of issues. International Environmental Education Programme (1975–1995) For two decades, UNESCO and UNEP led

3876-1245: The oceans and seas at the regional level. More than 143 countries participate in 18 regional programmes established by the Regional Seas Conventions and Action Plans, with 14 of them underpinned by legally binding international conventions, such as the Helsinki Convention , the Oslo Dumping Convention , the Barcelona Convention or the Bucharest Convention. The RSCAPs include the Caribbean region , East Asian seas, East African region, Mediterranean Basin , Pacific Northwest region, West African region, Caspian Sea , Black Sea region, Northeast Pacific region, Red Sea and Gulf of Aden , ROPME Sea Area, South Asian seas, Southeast Pacific region, Pacific region, Arctic region, Antarctic region, Baltic Sea , and Northeast Atlantic region. Each programme consists of countries which share

In addition, some definitions also include a topographical prominence requirement, such as that the mountain rises 300 metres (984 ft) above the surrounding terrain. At one time, the United States Board on Geographic Names defined a mountain as being 1,000 feet (305 m) or taller, but has abandoned

4012-527: The plants and animals residing on mountains. A particular set of plants and animals tend to be adapted to a relatively narrow range of climate. Thus, ecosystems tend to lie along elevation bands of roughly constant climate. This is called altitudinal zonation . In regions with dry climates, the tendency of mountains to have higher precipitation as well as lower temperatures also provides for varying conditions, which enhances zonation. Some plants and animals found in altitudinal zones tend to become isolated since

After developing organisations such as the International Labour Organization , the Food and Agriculture Organization and the World Health Organization , the 1972 United Nations Conference on the Human Environment (the Stockholm Conference) was convened. In this conference various topics were discussed such as pollution, marine life, protection of resources, environmental change, and disasters relating to natural and biological change. This conference resulted in

4284-514: The surface. When the magma reaches the surface, it often builds a volcanic mountain, such as a shield volcano or a stratovolcano . Examples of volcanoes include Mount Fuji in Japan and Mount Pinatubo in the Philippines. The magma does not have to reach the surface in order to create a mountain: magma that solidifies below ground can still form dome mountains , such as Navajo Mountain in

4352-477: The tallest mountain on land by this measure. The bases of mountain islands are below sea level, and given this consideration Mauna Kea (4,207 m (13,802 ft) above sea level) is the world's tallest mountain and volcano, rising about 10,203 m (33,474 ft) from the Pacific Ocean floor. The highest mountains are not generally the most voluminous. Mauna Loa (4,169 m or 13,678 ft)

4420-481: The tallest on earth. There is no universally accepted definition of a mountain. Elevation, volume, relief, steepness, spacing and continuity have been used as criteria for defining a mountain. In the Oxford English Dictionary a mountain is defined as "a natural elevation of the earth surface rising more or less abruptly from the surrounding level and attaining an altitude which, relatively to
