25zero
25zero is a mountaineering project, tracking Retreat of glaciers since 1850, equatorial glacial melt and raising awareness of the impacts of climate change, led by explorer Tim Jarvis Order of Australia, AM. The project was founded in 2014, and focussed on bringing live footage from the peaks of three mountain glaciers to the 37,000 delegates at the COP21 summit in 2015 in Paris, France, as a way of showcasing the impact of global warming on vulnerable and remote areas. In 2016 the 25zero project grew into a documentary film production, with a broader focus on both the glaciers themselves and the communities that live near them. The resulting 15-minute short film, entitled ''25zero//East Africa'', was released in 2019. Naming the project While many mountains straddle the equator, only 25 of these have a glacier at their peak (defined at the time of the United Nations Framework Convention on Climate Change adoption in 1992); hence, 25 mountains at zero latitude.

Retreat Of Glaciers Since 1850
The retreat of glaciers since 1850 affects the availability of fresh water for irrigation and domestic use, mountain recreation, animals and plants that depend on glacier-melt, and, in the longer term, the level of the oceans. Deglaciation occurs naturally at the end of ice ages, but glaciologists find the current glacier retreat is accelerated by the measured increase of atmospheric greenhouse gases—an effect of climate change. Mid-latitude mountain ranges such as the Himalayas, Rockies, Alps, Cascades, Southern Alps, and the southern Andes, as well as isolated tropical summits such as Mount Kilimanjaro in Africa, are showing some of the largest proportionate glacial losses. Excluding peripheral glaciers of ice sheets, the total cumulated global glacial losses over the 26 year period from 1993–2018 were likely 5500 gigatons, or 210 gigatons per yr.Fox-Kemper, B., H.T.

Nevado Del Ruiz
The Nevado del Ruiz (), also known as La Mesa de Herveo ( en, Mesa of Herveo, the name of the nearby town) is a volcano on the border of the departments of Caldas and Tolima in Colombia, about west of the capital city Bogotá. It is a stratovolcano composed of many layers of lava alternating with hardened volcanic ash and other pyroclastic rocks. Volcanic activity at Nevado del Ruiz began about two million years ago, since the Early Pleistocene or Late Pliocene, with three major eruptive periods. The current volcanic cone formed during the present eruptive period, which began 150,000 years ago. The volcano usually generates Vulcanian to Plinian eruptions, which produce swift-moving currents of hot gas and rock called pyroclastic flows. These eruptions often cause massive lahars (mud and debris flows), which pose a threat to human life and the environment. The impact of such an eruption is increased as the hot gas and lava melt the mountain's snowcap, adding large quantitie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nevado Del Quindío
The Nevado del Quindío is an inactive volcano located in the Central Cordillera of the Andes in central Colombia. The summit marks the tripoint of the departments of Risaralda, Quindío and Tolima, and is also the highest point of the departments of Risaralda and Quindío. The mountain is one of the highest peaks in the Los Nevados National Natural Park, which is a wildlife sanctuary. There are no historical records of any eruption. The andesitic volcano is located on top of the Palestina Fault.Plancha 225, 1998González, 2001 The snow fields and glaciers in the mountain are decreasing in a progressive way, about ten percent annually since the first scientific measures in the late 1980s, presumably because of global warming. The mountain offers beautiful landscapes, attracting touristic visits all the year. The lower part is a cloud forest habitat, rich in endemic species. Botanist and naturalist Alexander von Humboldt visited the area in 1801, describing new species such a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nevado Del Huila
Nevado del Huila (, ) at , is the highest volcano in Colombia, located at the tripoint of the departments of Huila, Tolima and Cauca. It is visible from the city of Cali. The andesitic volcano is located on top of the Ibagué Batholith.Plancha 322, 1999 After being dormant for more than 500 years, the volcano showed heavy signs of activity in 2007 and 2008. As of February 20, 2007, there were more than 7000 "minor" seismic events, and a high state of alert was in place for the departments of Cauca, Huila, Caldas and Valle del Cauca. The volcano erupted twice in April 2007, once in April 2008 and again in November 2008. Any eruption would affect the small villages around the volcano, mostly Páez, where their inhabitants still have in memory the eruption of the Nevado del Ruiz volcano and the destruction of Armero. Eruptions 2007 eruption On April 18, 2007, the volcano erupted twice causing avalanches into the Paez River; this event caused water levels to rise ...

Sincholagua Volcano
Sincholagua is an inactive volcano located in Ecuador northeast of Cotopaxi Volcano and southeast of Quito.Rachoweicki, Rob and Mark Thurber. ''Ecuador: Climbing and Hiking Guide''. Viva Pub. Network, 2008. p.208. It is the 12th highest peak in the country at but also one of the lesser known ones. The name of the mountain comes from the indigenous language Quichua and means "strong above".Brain, Yossi, ''Ecuador: A Climbing Guide'', Seattle: Mountaineers, 2000. p.125. Due to its close proximity to Cotopaxi, the second highest peak in Ecuador and the most popular volcano, it is far less frequently visited compared to other mountains in the country. It has a sharp peak and at one point had glacial cover year round, but all of the glaciers melted a few decades ago. However, snow can still be seen on the peak since there is sometimes heavy snowfall at the summit.http://www.summitpost.org/sincholagua/672776. Andean, Boriss.

Sangay
Sangay (also known as Macas, Sanagay, or Sangai) is an active stratovolcano in central Ecuador. It exhibits mostly strombolian activity. Geologically, Sangay marks the southern boundary of the Northern Volcanic Zone, and its position straddling two major pieces of crust accounts for its high level of activity. Sangay's approximately 500,000-year-old history is one of instability; two previous versions of the mountain were destroyed in massive flank collapses, evidence of which still litters its surroundings today. Due to its remoteness, Sangay hosts a significant biological community with fauna such as the mountain tapir, giant otter, Andean cock-of-the-rock and king vulture. Since 1983, its ecological community has been protected as part of the Sangay National Park. Although climbing the mountain is hampered by its remoteness, poor weather conditions, river flooding, and the danger of falling ejecta, the volcano is regularly climbed, a feat first achieved by Robert T. Moore ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

El Altar
El Altar or Capac Urcu (possibly from Kichwa ''kapak'' principal, great, important / magnificence, ''urku'' mountain) is an extinct volcano on the western side of Sangay National Park in Ecuador, south of Quito, with a highest point of . Spaniards named it so because it resembled two nuns and four friars listening to a bishop around a church altar. In older English sources it is also called The Altar. Geology El Altar consists of a large stratovolcano of Pliocene-Pleistocene age with a caldera breached to the west. Inca legends report that the top of El Altar collapsed after seven years of activity in about 1460, but the caldera is considered to be much older than this by geologists. Nine major peaks over form a horseshoe-shaped ridge about across, surrounding a central basin that contains a crater lake at about , known as Laguna Collanes or Laguna Amarilla. Access and recreation El Altar is perhaps the most technically demanding climb in Ecuador. The route to the El Obispo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cotopaxi
Cotopaxi () is an active stratovolcano in the Andes Mountains, located in Latacunga city of Cotopaxi Province, about south of Quito, and northeast of the city of Latacunga, Ecuador. It is the second highest summit in Ecuador, reaching a height of . Cotopaxi is among the highest active volcanoes in the world. Its most recent eruption began on 14 August 2015, and ended on 24 January 2016. Cotopaxi is known to have erupted 87 times, resulting in the creation of numerous valleys formed by lahars (mudflows) around the volcano. The last eruption lasted from August 2015 to January 2016. Cotopaxi was officially closed by the authorities to climbing until it reopened on October 7, 2017. Description On a clear day, Cotopaxi is clearly visible on the skyline from Latacunga and Quito. It is part of the chain of volcanoes around the Pacific plate known as the Pacific Ring of Fire. It has an almost symmetrical cone that rises from a highland plain of about , with a width at its ...
