The World Portal

The world is the totality of entities, the whole of reality, or everything that is. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique while others talk of a "plurality of worlds". Some treat the world as one simple object while others analyze the world as a complex made up of parts. In scientific cosmology, the world or universe is commonly defined as "[t]he totality of all space and time; all that is, has been, and will be". Theories of modality talk of possible worlds as complete and consistent ways how things could have been. Phenomenology, starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon or the "horizon of all horizons". In philosophy of mind, the world is contrasted with the mind as that which is represented by the mind. Theology conceptualizes the world in relation to God, for example, as God's creation, as identical to God or as the two being interdependent. In religions, there is a tendency to downgrade the material or sensory world in favor of a spiritual world to be sought through religious practice. A comprehensive representation of the world and our place in it, as is found in religions, is known as a worldview. Cosmogony is the field that studies the origin or creation of the world while eschatology refers to the science or doctrine of the last things or of the end of the world.

In various contexts, the term "world" takes a more restricted meaning associated, for example, with the Earth and all life on it, with humanity as a whole or with an international or intercontinental scope. In this sense, world history refers to the history of humanity as a whole and world politics is the discipline of political science studying issues that transcend nations and continents. Other examples include terms such as "world religion", "world language", "world government", "world war", "world population", "world economy" or "world championship". (Full article...)

A map of nations which have Lèse-majesté laws as of September 2022

Freedom of speech is the concept of the inherent human right to voice one's opinion publicly without fear of government censorship or punishment. "Speech" is not limited to public speaking and is generally taken to include other forms of expression. The right is preserved in the United Nations Universal Declaration of Human Rights and is granted formal recognition by the laws of most nations. Nonetheless, the degree to which the right is upheld in practice varies greatly from one nation to another. In many nations, particularly those with authoritarian forms of government, overt government censorship is enforced. Censorship has also been claimed to occur in other forms and there are different approaches to issues such as hate speech, obscenity, and defamation laws.

The following list is partially composed of the respective countries' government claims and does not fully reflect the de facto situation, however many sections of the page do contain information about the validity of the government's claims alongside said claims. (Full article...)

Universal Time (UT or UT1) is a time standard based on Earth's rotation. While originally it was mean solar time at 0° longitude, precise measurements of the Sun are difficult. Therefore, UT1 is computed from a measure of the Earth's angle with respect to the International Celestial Reference Frame (ICRF), called the Earth Rotation Angle (ERA, which serves as a modern replacement for Greenwich Mean Sidereal Time). UT1 is the same everywhere on Earth. UT1 is required to follow the relationship
:ERA = 2π(0.7790572732640 + 1.00273781191135448 · T_u) radians
where T_u = (Julian UT1 date - 2451545.0). (Full article...)

White Chuck Glacier in the United States in 1973

The retreat of glaciers since 1850 is well documented and is one of the effects of climate change. The retreat of mountain glaciers, notably in western North America, Asia, the Alps and tropical and subtropical regions of South America, Africa and Indonesia, provide evidence for the rise in global temperatures since the late 19th century. The acceleration of the rate of retreat since 1995 of key outlet glaciers of the Greenland and West Antarctic ice sheets may foreshadow a rise in sea level, which would affect coastal regions. Excluding peripheral glaciers of ice sheets, the total cumulated global glacial losses over the 26-year period from 1993 to 2018 were likely 5500 gigatons, or 210 gigatons per yr.

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 and is thus effect of climate change. Glacier mass balance is the key determinant of the health of a glacier. If the amount of frozen precipitation in the accumulation zone exceeds the quantity of glacial ice lost due to melting or in the ablation zone a glacier will advance; if the accumulation is less than the ablation, the glacier will retreat. Glaciers in retreat will have negative mass balances, and if they do not find an equilibrium between accumulation and ablation, will eventually disappear. (Full article...)

Global average temperatures show that the Medieval Warm Period was not a planet-wide phenomenon, and that the Little Ice Age was not a distinct planet-wide time period but rather the end of a long temperature decline that preceded recent global warming.

The temperature record of the last 2,000 years is reconstructed using data from climate proxy records in conjunction with the modern instrumental temperature record which only covers the last 170 years at a global scale. Large-scale reconstructions covering part or all of the 1st millennium and 2nd millennium have shown that recent temperatures are exceptional: the Intergovernmental Panel on Climate Change Fourth Assessment Report of 2007 concluded that "Average Northern Hemisphere temperatures during the second half of the 20th century were very likely higher than during any other 50-year period in the last 500 years and likely the highest in at least the past 1,300 years." The curve shown in graphs of these reconstructions is widely known as the hockey stick graph because of the sharp increase in temperatures during the last century. this broad pattern was supported by more than two dozen reconstructions, using various statistical methods and combinations of proxy records, with variations in how flat the pre-20th-century "shaft" appears. Sparseness of proxy records results in considerable uncertainty for earlier periods.

Individual proxy records, such as tree ring widths and densities used in dendroclimatology, are calibrated against the instrumental record for the period of overlap. Networks of such records are used to reconstruct past temperatures for regions: tree ring proxies have been used to reconstruct Northern Hemisphere extratropical temperatures (within the tropics trees do not form rings) but are confined to land areas and are scarce in the Southern Hemisphere which is largely ocean. Wider coverage is provided by multiproxy reconstructions, incorporating proxies such as lake sediments, ice cores and corals which are found in different regions, and using statistical methods to relate these sparser proxies to the greater numbers of tree ring records. The "Composite Plus Scaling" (CPS) method is widely used for large-scale multiproxy reconstructions of hemispheric or global average temperatures; this is complemented by Climate Field Reconstruction (CFR) methods which show how climate patterns have developed over large spatial areas, making the reconstruction useful for investigating natural variability and long-term oscillations as well as for comparisons with patterns produced by climate models.

The COVID-19 pandemic, also known as the coronavirus pandemic, is a global pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The novel virus was first identified in an outbreak in the Chinese city of Wuhan in December 2019, and spread to other areas of Asia and then worldwide in early 2020. The World Health Organization (WHO) declared the outbreak a public health emergency of international concern (PHEIC) on 30 January 2020. The WHO ended its PHEIC declaration on 5 May 2023. As of 23 January 2024, the pandemic has caused 774,144,371^[1] cases and 7,013,140^[1] confirmed deaths, ranking it fifth in the list of the deadliest epidemics and pandemics in history.

COVID-19 symptoms range from asymptomatic to deadly, but most commonly include fever, sore throat, nocturnal cough, and fatigue. Transmission of the virus is often through airborne particles. Mutations have produced many strains (variants) with varying degrees of infectivity and virulence. (Full article...)

Time zones of the world

A time zone is an area which observes a uniform standard time for legal, commercial and social purposes. Time zones tend to follow the boundaries between countries and their subdivisions instead of strictly following longitude, because it is convenient for areas in frequent communication to keep the same time.

Time zones are defined as one or two offsets from Coordinated Universal Time (UTC), and (if two offsets are used) the days when the offset changes. Some time zones switch between offsets throughout the year due to daylight saving time (DST). The UTC offsets range from UTC−12:00 to UTC+14:00, and are usually a whole number of hours, but a few zones are offset by an additional 30 or 45 minutes (such as in India, South Australia and Nepal).

Skyline of Buenos Aires from Puerto Madero

Buenos Aires (/ˌbweɪnəs ˈɛəriːz/ or /-ˈaɪrɪs/; Spanish pronunciation: [ˈbwenos ˈajɾes] ^ⓘ), officially the Autonomous City of Buenos Aires, is the capital and primate city of Argentina. The city is located on the western shore of the Río de la Plata, on South America's southeastern coast. "Buenos Aires" is Spanish for "fair winds" or "good airs". Buenos Aires is classified as an Alpha global city, according to the Globalization and World Cities Research Network (GaWC) 2020 ranking.

The city of Buenos Aires is neither part of Buenos Aires Province nor the Province's capital; rather, it is an autonomous district. In 1880, after decades of political infighting, Buenos Aires was federalized and removed from Buenos Aires Province. The city limits were enlarged to include the towns of Belgrano and Flores; both are now neighborhoods of the city. The 1994 constitutional amendment granted the city autonomy, hence its formal name of Autonomous City of Buenos Aires. Its citizens first elected a Chief of Government in 1996; previously, the Mayor was directly appointed by the President of Argentina. (Full article...)

Georgia (Georgian: საქართველო, romanized: sakartvelo, IPA: [sakʰartʰʷelo] ^ⓘ) is a transcontinental country located in Eastern Europe and West Asia. It is part of the Caucasus region, bounded by the Black Sea to the west, Russia to the north and northeast, Turkey to the southwest, Armenia to the south, and by Azerbaijan to the southeast. The country covers an area of 69,700 square kilometres (26,900 sq mi), and has a population of 3.7 million people. Tbilisi is its capital and largest city, home to roughly a third of the Georgian population.

Georgia has been a wine production site since 6,000 BC, being the earliest known location of winemaking in the world. During the classical era, several kingdoms emerged in what is now Georgia, such as Colchis and Iberia. In the early 4th century, Georgians officially adopted Christianity, which contributed to the unification of early Georgian states. In the Middle Ages, the unified Kingdom of Georgia reached its Golden Age during the reign of King David IV and Queen Tamar. Thereafter, the kingdom declined and eventually disintegrated under the hegemony of various regional powers, including the Mongols, the Ottoman Empire, and various dynasties of Persia. In 1783, one of the Georgian kingdoms entered into an alliance with the Russian Empire but Russia reneged on its promises and instead proceeded to annex the territory of modern Georgia piece-by-piece against the wish of the local rulers.

Protected areas of Canada consist of approximately 12.1 percent of the nation's landmass and freshwater are considered conservation areas, including 11.4 percent designated as protected areas. Approximately 13.8 percent of Canada's territorial waters are conserved, including 8.9 percent designated as protected areas. Terrestrial areas conserved have increased by 65 percent in the 21st century, while marine areas conserved have increased by more than 3,800 percent.

Conservation and protected areas have different mandates depending on the organization which manages them, with some areas having a greater focus on ecological integrity, historical preservation, public usage, scientific research, or a combination of usages. Some areas such as the Polar Bear Pass, are co-managed and overseen by government and local indigenous agencies. (Full article...)

According to the California Protected Areas Database (CPAD), in the state of California, United States, there are over 14,000 inventoried protected areas administered by public agencies and non-profits. In addition, there are private conservation areas and other easements. They include almost one-third of California's scenic coastline, including coastal wetlands, estuaries, beaches, and dune systems. The California State Parks system alone has 270 units and covers 1.3 million acres (5,300 km²), with over 280 miles (450 km) of coastline, 625 miles (1,006 km) of lake and river frontage, nearly 18,000 campsites, and 3,000 miles (5,000 km) of hiking, biking, and equestrian trails.

Obtaining an accurate total of all protected land in California and elsewhere is a complex task. Many parcels have inholdings, private lands within the protected areas, which may or may not be accounted for when calculating total area. Also, occasionally one parcel of land is included in two or more inventories. Over 90% of Yosemite National Park for example, is listed both as wilderness by the National Wilderness Preservation System, and as national park land by the National Park Service. The Cosumnes River Preserve is an extreme example, owned and managed by a handful of public agencies and private landowners, including the Bureau of Land Management, the County of Sacramento and The Nature Conservancy. Despite the difficulties, the CPAD gives the total area of protected land at 49,294,000 acres (199,490 km²), or 47.05% of the state (not including easements); a considerable amount for the most populous state in the country.

Protected areas of New Zealand are areas that are in some way protected to preserve their environmental, scientific, scenic, historical, cultural or recreational value. There are about 10,000 protected areas, covering about a third of the country. The method and aims of protection vary according to the importance of the resource and whether it is publicly or privately owned.

Nearly 30 percent of New Zealand's land mass is publicly owned with some degree of protection. Most of this land – about 80,000 square kilometres (31,000 sq mi) – is administered by the Department of Conservation. There are 13 national parks, thousands of reserves, 54 conservation parks, and a range of other conservation areas. (Full article...)
