Silverthrone Caldera
The Silverthrone Caldera is a potentially active caldera complex in southwestern British Columbia, Canada, located over northwest of the city of Vancouver and about west of Mount Waddington in the Pacific Ranges of the Coast Mountains. The caldera is one of the largest of the few calderas in western Canada, measuring about long (north-south) and wide (east-west). Mount Silverthrone, an eroded lava dome on the caldera's northern flank, which is high, may be the highest volcano in Canada. The main glaciers in the Silverthrone area are the Pashleth, Kingcome, Trudel, Klinaklini and Silverthrone glaciers. Most of the caldera lies in the Ha-Iltzuk Icefield, which is the largest icefield in the southern half of the Coast Mountains; it is one of the five icefields in southwestern British Columbia that thinned between the mid-1980s and 1999 due to global warming. Nearly half of the icefield is drained by the Klinaklini Glacier, which feeds the Klinaklini River. The Silvert ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cambridge University Press
Cambridge University Press was the university press of the University of Cambridge. Granted a letters patent by King Henry VIII in 1534, it was the oldest university press in the world. Cambridge University Press merged with Cambridge Assessment to form Cambridge University Press and Assessment under Queen Elizabeth II's approval in August 2021. With a global sales presence, publishing hubs, and offices in more than 40 countries, it published over 50,000 titles by authors from over 100 countries. Its publications include more than 420 academic journals, monographs, reference works, school and university textbooks, and English language teaching and learning publications. It also published Bibles, runs a bookshop in Cambridge, sells through Amazon, and has a conference venues business in Cambridge at the Pitt Building and the Sir Geoffrey Cass Sports and Social Centre.

Helicopter
A helicopter is a type of rotorcraft in which Lift (force), lift and thrust are supplied by horizontally spinning Helicopter rotor, rotors. This allows the helicopter to VTOL, take off and land vertically, to hover (helicopter), hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of short take-off and landing (STOL) or short take-off and vertical landing (STOVL) aircraft cannot perform without a runway. The Focke-Wulf Fw 61 was the first successful, practical, and fully controllable helicopter in 1936, while in 1942, the Sikorsky R-4 became the first helicopter to reach full-scale mass production, production. Starting in 1939 and through 1943, Igor Sikorsky worked on the development of the Vought-Sikorsky VS-300, VS-300, which over four iterations, became the basis for modern helicopters with a single main rotor and a single tail rotor.

Volcanologist
A volcanologist, or volcano scientist, is a geologist who focuses on understanding the formation and eruptive activity of volcanoes. Volcanologists frequently visit volcanoes, sometimes active ones, to observe and monitor volcanic eruptions, collect eruptive products including tephra (such as Volcanic ash, ash or pumice), Rock (geology), rock and lava samples. One major focus of inquiry in recent times is the prediction of eruptions to alleviate the impact on surrounding populations and monitor natural hazards associated with volcanic activity. Geologists who research volcanic materials that make up the solid Earth are referred to as igneous petrologists. Etymology The word ''volcanologist'' (or ''vulcanologist'') is derived from the English volcanology (volcano + wikt:-logy, -logy), which was derived from the French wikt:volcanologie#French, volcanologie (or vulcanologie), which was further derived from the French word wikt:volcan#French, volcan (volcano), which was even furt ...

Klinaklini River
The Klinaklini River ( Kwak'wala name T̓linat̓łina also spelled ƛ̓inaƛ̓ina) is one of the major rivers of the Pacific Ranges section of the Coast Mountains in the Canadian province of British Columbia. It originates in the Pantheon Range and empties into the head of Knight Inlet. A different spelling of ''Klinaklini'' is Kleena Kleene, which is the name of a recreational community on the river just below its exit from the Pantheon Range onto the Chilcotin Plateau. In the area of Kleena Kleene the Klinaklini, Homathko and Chilanko River basins share the same stretch of plateau. The names Kleena Kleene and Klinaklini derive from the Kwak'wala word for eulachon grease, which is made from the eulachon, a small oily fish that ascend coastal rivers. There is a First Nation village of the Tanakteuk subdivision of the Kwakwaka'wakw peoples at the mouth of the river, Tsawatti. Located on the Indian Reserve of the same name, it is the primary eulachon fishing and preservati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Global Warming
Present-day climate change includes both global warming—the ongoing increase in global average temperature—and its wider effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global temperatures is driven by human activities, especially fossil fuel burning since the Industrial Revolution. Fossil fuel use, deforestation, and some agricultural and industrial practices release greenhouse gases. These gases absorb some of the heat that the Earth radiates after it warms from sunlight, warming the lower atmosphere. Carbon dioxide, the primary gas driving global warming, has increased in concentration by about 50% since the pre-industrial era to levels not seen for millions of years. Climate change has an increasingly large impact on the environment. Deserts are expanding, while heat waves and wildfires are becoming more common. Amplified warming in the Arctic has c ...

Ha-Iltzuk Icefield
The Ha-Iltzuk Icefield is an icefield in the central Pacific Ranges of the Coast Mountains in British Columbia, Canada. It is the largest icefield in the Coast Mountains south of the Alaska Panhandle, with an area of . It is located on the west side of the Klinaklini River and the Waddington Range. The highest summit in the icefield is Mount Silverthrone, which is a mountain on the northeast edge of a circular, wide, deeply dissected caldera complex called the Silverthrone Caldera. The southern half of the icefield is named the Silverthrone Glacier and flows west, joining the Klinaklini Glacier just above that glacier's terminus, where its outflow is short but very large, and joins the Klinaklini River within a few kilometres. The Klinaklini Glacier constitutes the northern half of the icefield, and off its northwest edge a glacial tongue produces the head of the Machmell River. The name Ha-Iltzuk Icefield does not appear in government gazettes. The term is almost cer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
