Cape Grim
Cape Grim, officially Kennaook / Cape Grim, is the northwestern point of Tasmania, Australia. The Peerapper name for the cape is recorded as ''Kennaook''. It is the location of the Cape Grim Baseline Air Pollution Station and of the Cape Grim Air Archive which is operated by the Australian Bureau of Meteorology in a joint programme with the CSIRO. The station was established in 1976 and has been operating ever since. The data from Cape Grim have been used extensively in assessments of climate change and ozone depletion. Geography Cape Grim's isolated geographic location makes it unique. The next land mass directly west of Cape Grim is not Africa, but the southern tip of Argentina. Winds that make their way to Cape Grim from Antarctica and the Indian Ocean hit no significant land mass. Air pollution values collected at Cape Grim are the closest attainable representation of a global average. History The headland was first charted and named Cape Grim by Matthew Flinders on 7 D ...

Cape (geography)
In geography, a cape is a headland, peninsula or promontory extending into a body of water, usually a sea. A cape usually represents a marked change in trend of the Coast, coastline, often making them important landmarks in sea navigation. This also makes them prone to natural forms of erosion, mainly tidal actions, resulting in a relatively short geological lifespan. Formation Capes can be formed by Glacier, glaciers, Volcano, volcanoes, and changes in sea level. Erosion plays a large role in each of these methods of formation. Coastal erosion by waves and currents can create capes by wearing away softer rock and leaving behind harder rock formations. Movements of the Earth's crust can uplift land, forming capes. For example, the Cape of Good Hope was formed by tectonic forces. Volcanic eruptions can create capes by depositing lava that solidifies into new landforms. Cape Verde, (also known as Cabo Verde) is an example of a volcanic cape. Glaciers can carve out capes by erod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ozone Depletion
Ozone depletion consists of two related events observed since the late 1970s: a lowered total amount of ozone in Earth, Earth's upper atmosphere, and a much larger springtime decrease in stratospheric ozone (the ozone layer) around Earth's polar regions. The latter phenomenon is referred to as the #Ozone hole and its causes, ozone hole. There are also springtime polar tropospheric ozone depletion events in addition to these stratospheric events. The main causes of ozone depletion and the ozone hole are manufactured chemicals, especially manufactured halocarbon refrigerants, solvents, propellants, and foam-blowing agents (chlorofluorocarbons (CFCs), HCFCs, Haloalkanes, halons), referred to as ''ozone-depleting substances'' (ODS). These compounds are transported into the stratosphere by Turbulence, turbulent mixing after being emitted from the surface, mixing much faster than the molecules can settle. Once in the stratosphere, they release atoms from the halogen group through photod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allen & Unwin
George Allen & Unwin was a British publishing company formed in 1911 when Sir Stanley Unwin purchased a controlling interest in George Allen & Co. It became one of the leading publishers of the twentieth century and established an Australian subsidiary in 1976. In 1990 Allen & Unwin was sold to HarperCollins, and the Australian branch was the subject of a management buy-out. George Allen & Unwin in the UK George Allen & Sons was established in 1871 by George Allen, with the backing of John Ruskin, becoming George Allen & Co. Ltd. in 1911 when it merged with Swan Sonnenschein and then George Allen & Unwin on 4 August 1914 as a result of Stanley Unwin's purchase of a controlling interest. Frank Arthur Mumby and Frances Helena Swan Stallybrass, Unwin's son Rayner S. Unwin and his nephew Philip helped him to run the company, which published works by Bertrand Russell, Arthur Waley, Roald Dahl, Lancelot Hogben and Thor Heyerdahl. It became well known as J. R. R. Tolkien's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aboriginal Tasmanians
The Aboriginal Tasmanians (palawa kani: ''Palawa'' or ''Pakana'') are the Aboriginal people of the Australian island of Tasmania, located south of the mainland. At the time of European contact, Aboriginal Tasmanians were divided into a number of distinct ethnic groups. For much of the 20th century, the Tasmanian Aboriginal people were widely, and erroneously, thought of as extinct and intentionally exterminated by white settlers. Contemporary figures (2016) for the number of people of Tasmanian Aboriginal descent vary according to the criteria used to determine this identity, ranging from 6,000 to over 23,000. First arriving in Tasmania (then a peninsula of Australia) around 40,000 years ago, the ancestors of the Aboriginal Tasmanians were cut off from the Australian mainland by rising sea levels 6000 BC. They were entirely isolated from the outside world for 8,000 years until European contact. Before British colonisation of Tasmania in 1803, there were an estimated ...

Cape Grim Massacre
The Cape Grim massacre was an attack on 10 February 1828 in which a group of Aboriginal Tasmanians gathering food at a beach in the north-west of Tasmania is said to have been ambushed and shot by four Van Diemen's Land Company (VDLC) workers, with bodies of some of the victims then thrown from a cliff. About 30 men are thought to have been killed in the attack, which was a reprisal action for an earlier Aboriginal raid on a flock of Van Diemen's Land Company sheep, but part of an escalating spiral of violence probably triggered by the abduction and rape of Aboriginal women in the area. The massacre was part of the "Black War", the period of violent conflict between British Empire, British colonists and Aboriginal Australians in Tasmania from the mid-1820s to 1832. News of the Cape Grim killings did not reach Governor Sir George Arthur, 1st Baronet, George Arthur for almost two years. Arthur sent George Augustus Robinson, who held an unofficial government role as an Aboriginal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Van Diemen's Land
Van Diemen's Land was the colonial name of the island of Tasmania during the European exploration of Australia, European exploration and colonisation of Australia in the 19th century. The Aboriginal Tasmanians, Aboriginal-inhabited island was first visited by the Dutch ship captained by Abel Tasman in 1642, working under the sponsorship of Anthony van Diemen, the Governor-General of the Dutch East Indies. The British retained the name when they established a settlement in 1803 before it became a separate colony in 1825. Its Penal colony, penal colonies became notorious destinations for the Convicts in Australia, transportation of convicts due to the harsh environment, isolation and reputation for being escape-proof. The name was changed to Tasmania on 1st January 1856 to disassociate the island from its convict past and to honour its discoverer, Abel Tasman. The old name had become a byword for horror in England because of the severity of its convict settlements such as Macq ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norfolk (sloop)
The Colonial sloop ''Norfolk'' was built on Norfolk Island in 1798. It was wrecked in 1800. David Collins recorded in his ''Account of the English Colony in New South Wales: ''"The necessity of a vessel to keep up a more frequent intercourse with Norfolk Island, ...having been much felt by the want of various stores ...occasioned Captain Townson, the Commanding officer, to construct a small decked boat, sloop rigged, in which he sent His letters to this port..."'' Cumpston describes ''Norfolk'' as, “A decked longboat built at Norfolk Iland” Governor Hunter put the ''Norfolk'' under the command of Matthew Flinders, the Sailing Master Peter Hibbs (seaman formerly on the "Sirius"). The vessel was to be used as a survey vessel and in that capacity was used by Flinders and Bass in 1798-99 to circumnavigate Van Diemens Land (Tasmania) – proving the existence of Bass Strait. Flinders also took ''Norfolk'' north to chart Cook's ''Morton's Bay'' (now Moreton Bay) and Hervey' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Matthew Flinders
Captain (Royal Navy), Captain Matthew Flinders (16 March 1774 – 19 July 1814) was a British Royal Navy officer, navigator and cartographer who led the first littoral zone, inshore circumnavigate, circumnavigation of mainland Australia, then called New Holland (Australia), New Holland. He is also credited as being the first person to utilise the name ''Australia'' to describe the entirety of that continent including Van Diemen's Land (now Tasmania), a title he regarded as being "more agreeable to the ear" than previous names such as ''Terra Australis''. Flinders was involved in several voyages of discovery between 1791 and 1803, the most famous of which are the circumnavigation of Australia and an earlier expedition when he and George Bass confirmed that Van Diemen's Land was an island. While returning to Britain in 1803, Flinders was arrested by the French at the colony of Isle de France (Mauritius), Isle de France. Although Britain and France were at war, Flinders thought t ...

Air Pollution
Air pollution is the presence of substances in the Atmosphere of Earth, air that are harmful to humans, other living beings or the environment. Pollutants can be Gas, gases like Ground-level ozone, ozone or nitrogen oxides or small particles like soot and dust. It affects both outdoor air and indoor air. Natural sources of air pollution include Wildfire, wildfires, Dust storm, dust storms, and Volcanic eruption, volcanic eruptions. Indoor air pollution is often Energy poverty and cooking, caused by the use of biomass (e.g. wood) for cooking and heating. Outdoor air pollution comes from some industrial processes, the burning of Fossil fuel, fossil fuels for electricity and transport, waste management and agriculture. Many of the contributors of local air pollution, especially the burning of fossil fuels, also cause greenhouse gas emissions that cause climate change, global warming. Air pollution causes around 7 or 8 million deaths each year. It is a significant risk factor for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climate Change
Present-day climate change includes both global warming—the ongoing increase in Global surface temperature, global average temperature—and its wider effects on Earth's climate system. Climate variability and change, Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global temperatures is Scientific consensus on climate change, driven by human activities, especially fossil fuel burning since the Industrial Revolution. Fossil fuel use, Deforestation and climate change, deforestation, and some Greenhouse gas emissions from agriculture, agricultural and Environmental impact of concrete, industrial practices release greenhouse gases. These gases greenhouse effect, absorb some of the heat that the Earth Thermal radiation, radiates after it warms from sunlight, warming the lower atmosphere.

The Doughboys (Tasmania)
The Doughboys are a pair of islands near Cape Grim, the northwestern point of Tasmania, Australia. The western island has an area of and the eastern island has an area of . The two islands form part of the Trefoil Island Group.Brothers, Nigel; Pemberton, David; Pryor, Helen; & Halley, Vanessa. (2001). ''Tasmania's Offshore Islands: seabirds and other natural features''. Tasmanian Museum and Art Gallery: Hobart. In June 2021, the Tasmanian Department of Primary Industries, Parks, Water and Environment, after consultation with local Aboriginal groups, approved the dual naming of the island pair as Koindrim. The dual name is intended to be represented in maps and publications as Koindrim / The Doughboys. This followed the approval in March 2021, after similar consultation, of names for the two islands. The eastern island's new name is Kaninerwidic (pronounced (Ka_nina_widic), while the westernmost one is Karrernootong (pronounced Kara_nu_tong). Fauna The islands are part of t ...
