Glacier National Park is an American national park located in northwestern Montana, on the Canada–United States border, adjacent to the Canadian provinces of Alberta and British Columbia. The park encompasses more than 1 million acres (4,000 km²) and includes parts of two mountain ranges (sub-ranges of the Rocky Mountains), more than 130 named lakes, more than 1,000 different species of plants, and hundreds of species of animals. This vast pristine ecosystem is the centerpiece of what has been referred to as the "Crown of the Continent Ecosystem," a region of protected land encompassing 16,000 square miles (41,000 km²).

The region that became Glacier National Park was first inhabited by Native Americans. Upon the arrival of European explorers, it was dominated by the Blackfeet in the east and the Flathead in the western regions. Under pressure, the Blackfeet ceded the mountainous parts of their treaty lands in 1895 to the federal government; it later became part of the park. Soon after the establishment of the park on May 11, 1910, a number of hotels and chalets were constructed by the Great Northern Railway. These historic hotels and chalets are listed as National Historic Landmarks and a total of 350 locations are on the National Register of Historic Places. By 1932 work was completed on the Going-to-the-Sun Road, later designated a National Historic Civil Engineering Landmark, which provided greater accessibility for automobiles into the heart of the park.

Adults with a chick on Snow Hill Island, Antarctic Peninsula

The emperor penguin (Aptenodytes forsteri) is the tallest and heaviest of all living penguin species and is endemic to Antarctica. The male and female are similar in plumage and size, reaching 100 cm (39 in) in length and weighing from 22 to 45 kg (49 to 99 lb). Feathers of the head and back are black and sharply delineated from the white belly, pale-yellow breast and bright-yellow ear patches.

Like all penguins, it is flightless, with a streamlined body, and wings stiffened and flattened into flippers for a marine habitat. Its diet consists primarily of fish, but also includes crustaceans, such as krill, and cephalopods, such as squid. While hunting, the species can remain submerged around 20 minutes, diving to a depth of 535 m (1,755 ft). It has several adaptations to facilitate this, including an unusually structured haemoglobin to allow it to function at low oxygen levels, solid bones to reduce barotrauma, and the ability to reduce its metabolism and shut down non-essential organ functions.

Sunset at Biscayne National Park

Biscayne National Park is an American national park located south of Miami, Florida in Miami-Dade County. The park preserves Biscayne Bay and its offshore barrier reefs. Ninety-five percent of the park is water, and the shore of the bay is the location of an extensive mangrove forest. The park covers 172,971 acres (270.3 sq mi; 700.0 km²) and includes Elliott Key, the park's largest island and northernmost of the true Florida Keys, formed from fossilized coral reef. The islands farther north in the park are transitional islands of coral and sand. The offshore portion of the park includes the northernmost region of the Florida Reef, one of the largest coral reefs in the world.

Biscayne National Park protects four distinct ecosystems: the shoreline mangrove swamp, the shallow waters of Biscayne Bay, the coral limestone keys and the offshore Florida Reef. The shoreline swamps of the mainland and island margins provide a nursery for larval and juvenile fish, molluscs and crustaceans. The bay waters harbor immature and adult fish, seagrass beds, sponges, soft corals, and manatees. The keys are covered with tropical vegetation including endangered cacti and palms, and their beaches provide nesting grounds for endangered sea turtles. Offshore reefs and waters harbor more than 200 species of fish, pelagic birds, whales and hard corals. Sixteen endangered species including Schaus' swallowtail butterflies, smalltooth sawfish, manatees, and green and hawksbill sea turtles may be observed in the park. Biscayne also has a small population of threatened American crocodiles and a few American alligators. (Full article...)

Grand Canyon of the Yellowstone

Yellowstone National Park is an American national park located in the western United States, largely in the northwest corner of Wyoming and extending into Montana and Idaho. It was established by the 42nd U.S. Congress with the Yellowstone National Park Protection Act and signed into law by President Ulysses S. Grant on March 1, 1872. Yellowstone was the first national park in the U.S. and is also widely held to be the first national park in the world. The park is known for its wildlife and its many geothermal features, especially the Old Faithful geyser, one of its most popular. While it represents many types of biomes, the subalpine forest is the most abundant. It is part of the South Central Rockies forests ecoregion.

While Native Americans have lived in the Yellowstone region for at least 11,000 years, aside from visits by mountain men during the early-to-mid-19th century, organized exploration did not begin until the late 1860s. Management and control of the park originally fell under the jurisdiction of the United States Department of the Interior, the first Secretary of the Interior to supervise the park being Columbus Delano. However, the U.S. Army was eventually commissioned to oversee management of Yellowstone for a 30-year period between 1886 and 1916. In 1917, administration of the park was transferred to the National Park Service, which had been created the previous year. Hundreds of structures have been built and are protected for their architectural and historical significance, and researchers have examined more than a thousand archaeological sites.

Ireland is an island in Northern Europe in the north Atlantic Ocean. The island lies on the European continental shelf, part of the Eurasian Plate. The island's main geographical features include low central plains surrounded by coastal mountains. The highest peak is Carrauntoohil (Irish: Corrán Tuathail), which is 1,039 metres (3,409 ft) above sea level. The western coastline is rugged, with many islands, peninsulas, headlands and bays. The island is bisected by the River Shannon, which at 360.5 km (224 mi) with a 102.1 km (63 mi) estuary is the longest river in Ireland and flows south from County Cavan in Ulster to meet the Atlantic just south of Limerick. There are a number of sizeable lakes along Ireland's rivers, of which Lough Neagh is the largest.

Politically, the island consists of the Republic of Ireland, with jurisdiction over about five-sixths of the island, and Northern Ireland, a constituent country of the United Kingdom, with jurisdiction over the remaining sixth. Located west of the island of Great Britain, it is located at approximately . It has a total area of 84,421 km² (32,595 sq mi). It is separated from Great Britain by the Irish Sea and from mainland Europe by the Celtic Sea.
Ireland forms the second largest landmass in the North-West European Archipelago, together with nearby islands including Great Britain and the Isle of Man, known in the United Kingdom as the British Isles. (Full article...)

Lithograph of Weissenburg in 1902

SMS Weissenburg was one of the first ocean-going battleships of the Imperial German Navy. She was the third pre-dreadnought of the Brandenburg class, which also included her sister ships Brandenburg, Wörth, and Kurfürst Friedrich Wilhelm. Weissenburg was laid down in 1890 in the AG Vulcan dockyard in Stettin, launched in 1891, and completed in 1894. The Brandenburg-class battleships were unique for their era in that they carried six large-caliber guns in three twin turrets, as opposed to four guns in two turrets, as was the standard in other navies.
Weissenburg served with I Division during the first decade of her service with the fleet. This period was generally limited to training exercises and goodwill visits to foreign ports. These training maneuvers were nevertheless very important to developing German naval tactical doctrine in the two decades before World War I, especially under the direction of Alfred von Tirpitz. Weissenburg, along with her three sisters, saw only one major overseas deployment during this period, to China in 1900–1901, during the Boxer Uprising. The ship underwent a major modernization in 1904–1905. (Full article...)

The air-tractor sledge was a converted fixed-wing aircraft taken on the 1911–1914 Australasian Antarctic Expedition, the first plane to be taken to the Antarctic.

Expedition leader Douglas Mawson had planned to use the Vickers R.E.P. Type Monoplane as a reconnaissance and search and rescue tool, and to assist in publicity, but the aircraft crashed heavily during a test flight in Adelaide, only two months before Mawson's scheduled departure date. The plane was nevertheless sent south with the expedition, after having been stripped of its wings and metal sheathing from the fuselage. (Full article...)

The orca or killer whale (Orcinus orca) is a toothed whale belonging to the oceanic dolphin family, of which it is the largest member. It is the only extant species in the genus Orcinus and is recognizable by its black-and-white patterned body. A cosmopolitan species, orcas can be found in all of the world's oceans in a variety of marine environments, from Arctic and Antarctic regions to tropical seas.

Orcas have a diverse diet, although individual populations often specialize in particular types of prey. Some feed exclusively on fish, while others hunt marine mammals such as seals and other species of dolphin. They have been known to attack baleen whale calves, and even adult whales. Orcas are apex predators, as they have no natural predators. They are highly social; some populations are composed of very stable matrilineal family groups (pods) which are the most stable of any animal species. Their sophisticated hunting techniques and vocal behaviours, which are often specific to a particular group and passed across generations, have been described as manifestations of animal culture.

The 2002 Pacific typhoon season was a slightly above average Pacific typhoon season, producing twenty-six named storms, fifteen becoming typhoons, and eight super typhoons. It was an event in the annual cycle of tropical cyclone formation, in which tropical cyclones form in the western Pacific Ocean. The season ran throughout 2002, though most tropical cyclones typically develop between May and October. The season's first named storm, Tapah, developed on January 11, while the season's last named storm, Pongsona, dissipated on December 11. The season's first typhoon, Mitag, reached typhoon status on March 1, and became the first super typhoon of the year four days later.

The scope of this article is limited to the Pacific Ocean, to the north of the equator between 100°E and the 180th meridian. Within the northwestern Pacific Ocean, there are two separate agencies that assign names to tropical cyclones, which can often result in a cyclone having two names, one from the JMA and one from PAGASA. The Japan Meteorological Agency (JMA) will name a tropical cyclone should it be judged to have 10-minute sustained wind speeds of at least 65 km/h (40 mph) anywhere in the basin, while the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) assigns names to tropical cyclones which move into or form as a tropical depression in their area of responsibility located between 135°E and 115°E and between 5°N–25°N regardless of whether or not a tropical cyclone has already been given a name by the JMA. Tropical depressions that are monitored by the United States' Joint Typhoon Warning Center (JTWC) are given a number with a "W" suffix. (Full article...)

Trafford Town Hall

Trafford is a metropolitan borough of Greater Manchester, England, with an estimated population of 235,493 in 2017. It covers 41 square miles (106 km²) and includes the area of Old Trafford and the towns of Altrincham, Stretford, Urmston, Partington and Sale. The borough was formed in 1974 as a merger of six former districts and part of a seventh. The River Mersey flows through the borough, separating North Trafford from South Trafford, and the historic counties of Lancashire and Cheshire. Trafford is the fifth-most populous district in Greater Manchester.

There is evidence of Neolithic, Bronze Age, and Roman activity in the area, two castles – one of them a Scheduled Ancient Monument – and over 200 listed buildings. In the late 19th century, the population rapidly expanded with the arrival of the railway. Trafford is the home of Altrincham Football Club, Trafford Football Club, Manchester United F.C. and Lancashire County Cricket Club and since 2002 the Imperial War Museum North. (Full article...)

The church at Waltham Abbey, where Hugh de Neville was buried

Hugh de Neville (died 1234) was the Chief Forester under the kings Richard I, John and Henry III of England; he was the sheriff for a number of counties. Related to a number of other royal officials as well as a bishop, Neville was a member of Prince Richard's household. After Richard became king in 1189, Neville continued in his service and accompanied him on the Third Crusade. Neville remained in the royal service following Richard's death in 1199 and the accession of King John to the throne, becoming one of the new king's favourites and often gambling with him. He was named in Magna Carta as one of John's principal advisers, and considered by a medieval chronicler to be one of King John's "evil counsellors". He deserted John after the French invasion of England in 1216 but returned to pledge his loyalty to John's son Henry III after the latter's accession to the throne later that year. Neville's royal service continued until his death in 1234, though by then he was a less significant figure than he had been at the height of his powers. (Full article...)

Dom Pedro II around age 61, c. 1887

Dom Pedro II (2 December 1825 – 5 December 1891), nicknamed the Magnanimous (Portuguese: O Magnânimo), was the second and last monarch of the Empire of Brazil, reigning for over 58 years. He was born in Rio de Janeiro, the seventh child of Emperor Dom Pedro I of Brazil and Empress Dona Maria Leopoldina and thus a member of the Brazilian branch of the House of Braganza. His father's abrupt abdication and departure to Europe in 1831 left the five-year-old as emperor and led to a grim and lonely childhood and adolescence, obliged to spend his time studying in preparation for rule. His experiences with court intrigues and political disputes during this period greatly affected his later character; he grew into a man with a strong sense of duty and devotion toward his country and his people, yet increasingly resentful of his role as monarch.

Pedro II inherited an empire on the verge of disintegration, but he turned Brazil into an emerging power in the international arena. The nation grew to be distinguished from its Hispanic neighbors on account of its political stability, zealously guarded freedom of speech, respect for civil rights, vibrant economic growth, and form of government—a functional representative parliamentary monarchy. Brazil was also victorious in the Platine War, the Uruguayan War, and the Paraguayan War, as well as prevailing in several other international disputes and domestic tensions. Pedro II steadfastly pushed through the abolition of slavery despite opposition from powerful political and economic interests. A savant in his own right, the Emperor established a reputation as a vigorous sponsor of learning, culture, and the sciences, and he won the respect and admiration of people such as Charles Darwin, Victor Hugo, and Friedrich Nietzsche, and was a friend to Richard Wagner, Louis Pasteur, and Henry Wadsworth Longfellow, among others.

Brownhills is a town and former administrative centre in the Metropolitan Borough of Walsall, West Midlands, England. A few miles south of Cannock Chase and close to the large Chasewater reservoir, it is 6 miles (9.7 km) northeast of Walsall, a similar distance southwest of Lichfield and 13 miles (20.9 km) miles north-northwest of Birmingham. It is part of the Aldridge-Brownhills parliamentary constituency and neighbours the large suburban villages of Pelsall and Walsall Wood. It lies within the boundaries of the historic county of Staffordshire.

The town lies close to the route of the ancient Watling Street, and although there is no record of its existence before the 17th century, Ogley Hay – a district of the town today – is recorded as a settlement in the Domesday Book. Brownhills quickly grew around the coal-mining industry, especially after the town became linked to the canal and railway networks in the mid-19th century. By the end of the century, Brownhills had grown from a hamlet of only 300 inhabitants to a town of more than 13,000, of whom the vast majority were employed in the coal industry. Mining remained the town's principal industry until the 1950s; the subsequent closure of the pits led to a severe economic decline that has continued until the present. The local authority instituted a regeneration programme in 2007, which was hoped would revive the town's fortunes, but there has been little subsequent development. (Full article...)

Winnipeg (/ˈwɪnɪpɛɡ/ (listen)) is the capital and largest city of the province of Manitoba in Canada. It is centred on the confluence of the Red and Assiniboine rivers, near the longitudinal centre of North America. , Winnipeg had a city population of 749,607 and a metropolitan population of 834,678, making it the sixth-largest city, and eighth-largest metropolitan area in Canada.

The city is named after the nearby Lake Winnipeg; the name comes from the Western Cree words for "muddy water" - “winipīhk”. The region was a trading centre for Indigenous peoples long before the arrival of Europeans; it is the traditional territory of the Anishinabe (Ojibway), Ininew (Cree), Oji-Cree, Dene, and Dakota, and is the birthplace of the Métis Nation. French traders built the first fort on the site in 1738. A settlement was later founded by the Selkirk settlers of the Red River Colony in 1812, the nucleus of which was incorporated as the City of Winnipeg in 1873. Being far inland, the local climate is extremely seasonal even by Canadian standards with average January highs of around −11 °C (12 °F) and average July highs of 26 °C (79 °F). (Full article...)

An ice core is a core sample that is typically removed from an ice sheet or a high mountain glacier. Since the ice forms from the incremental buildup of annual layers of snow, lower layers are older than upper ones, and an ice core contains ice formed over a range of years. Cores are drilled with hand augers (for shallow holes) or powered drills; they can reach depths of over two miles (3.2 km), and contain ice up to 800,000 years old.

The physical properties of the ice and of material trapped in it can be used to reconstruct the climate over the age range of the core. The proportions of different oxygen and hydrogen isotopes provide information about ancient temperatures, and the air trapped in tiny bubbles can be analysed to determine the level of atmospheric gases such as carbon dioxide. Since heat flow in a large ice sheet is very slow, the borehole temperature is another indicator of temperature in the past. These data can be combined to find the climate model that best fits all the available data. (Full article...)

Clockwise from top: City of London in the foreground with Canary Wharf in the far background; Trafalgar Square; London Eye; Tower Bridge; and a London Underground roundel in front of Elizabeth Tower

London is the capital and largest city of England and the United Kingdom, with a population of just under 9 million. It stands on the River Thames in south-east England at the head of a 50-mile (80 km) estuary down to the North Sea, and has been a major settlement for two millennia. The City of London, its ancient core and financial centre, was founded by the Romans as Londinium and retains its medieval boundaries. The City of Westminster, to the west of the City of London, has for centuries hosted the national government and parliament. Since the 19th century, the name "London" has also referred to the metropolis around this core, historically split between the counties of Middlesex, Essex, Surrey, Kent, and Hertfordshire, which since 1965 has largely comprised Greater London, which is governed by 33 local authorities and the Greater London Authority.

The United States of America is a federal republic consisting of 50 states, a federal district (Washington, D.C., the capital city of the United States), five major territories, and various minor islands. Both the states and the United States as a whole are each sovereign jurisdictions. The Tenth Amendment to the United States Constitution allows states to exercise all powers of government not delegated to the federal government. Each state has its own constitution and government, and all states and their residents are represented in the federal Congress, a bicameral legislature consisting of the Senate and the House of Representatives. Each state is represented by two senators, while representatives are distributed among the states in proportion to the most recent constitutionally mandated decennial census. Additionally, each state is entitled to select a number of electors to vote in the Electoral College, the body that elects the president of the United States, equal to the total of representatives and senators in Congress from that state. The federal district does not have representatives in the Senate, but has a non-voting delegate in the House, and it is also entitled to electors in the Electoral College. Congress can admit more states, but it cannot create a new state from territory of an existing state or merge of two or more states into one without the consent of all states involved, and each new state is admitted on an equal footing with the existing states.
