*The Blue Marble*, a photograph of the planet Earth made on 7 December 1972 by the crew of the Apollo 17 spacecraft.

The world is the totality of entities, the whole of reality, or everything that exists. 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 "the 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...)

IDA logo

The International Development Association (IDA) (French: Association internationale de développement) is a development finance institution which offers concessional loans and grants to the world's poorest developing countries. The IDA is a member of the World Bank Group and is headquartered in Washington, D.C. in the United States. It was established in 1960 to complement the existing International Bank for Reconstruction and Development by lending to developing countries which suffer from the lowest gross national income, from troubled creditworthiness, or from the lowest per capita income. Together, the International Development Association and International Bank for Reconstruction and Development are collectively generally known as the World Bank, as they follow the same executive leadership and operate with the same staff.

The association shares the World Bank's mission of reducing poverty and aims to provide affordable development financing to countries whose credit risk is so prohibitive that they cannot afford to borrow commercially or from the Bank's other programs. The IDA's stated aim is to assist the poorest nations in growing more quickly, equitably, and sustainably to reduce poverty. The IDA is the single largest provider of funds to economic and human development projects in the world's poorest nations. From 2000 to 2010, it financed projects which recruited and trained 3 million teachers, immunized 310 million children, funded $792 million in loans to 120,000 small and medium enterprises, built or restored 118,000 kilometers of paved roads, built or restored 1,600 bridges, and expanded access to improved water to 113 million people and improved sanitation facilities to 5.8 million people. The IDA has issued a total US$238 billion in loans and grants since its launch in 1960. Thirty-six of the association's borrowing countries have graduated from their eligibility for its concessional lending. However, nine of these countries have relapsed and have not re-graduated.

Astronomer Copernicus, or Conversations with God by Jan Matejko, 1873

The Scientific Revolution was a series of events that marked the emergence of modern science during the early modern period, when developments in mathematics, physics, astronomy, biology (including human anatomy) and chemistry transformed the views of society about nature. The Scientific Revolution took place in Europe in the second half of the Renaissance period, with the 1543 Nicolaus Copernicus publication De revolutionibus orbium coelestium (On the Revolutions of the Heavenly Spheres) often cited as its beginning. The Scientific Revolution has been called "the most important transformation in human history" since the Neolithic Revolution.

The era of the Scientific Renaissance focused to some degree on recovering the knowledge of the ancients and is considered to have culminated in Isaac Newton's 1687 publication Principia which formulated the laws of motion and universal gravitation, thereby completing the synthesis of a new cosmology. The subsequent Age of Enlightenment saw the concept of a scientific revolution emerge in the 18th-century work of Jean Sylvain Bailly, who described a two-stage process of sweeping away the old and establishing the new. There continues to be scholarly engagement regarding the boundaries of the Scientific Revolution and its chronology. (Full article...)

The Special Report on Global Warming of 1.5 °C (SR15) was published by the Intergovernmental Panel on Climate Change (IPCC) on 8 October 2018. The report, approved in Incheon, South Korea, includes over 6,000 scientific references, and was prepared by 91 authors from 40 countries. In December 2015, the 2015 United Nations Climate Change Conference called for the report. The report was delivered at the United Nations' 48th session of the IPCC to "deliver the authoritative, scientific guide for governments" to deal with climate change. Its key finding is that meeting a 1.5 °C (2.7 °F) target is possible but would require "deep emissions reductions" and "rapid, far-reaching and unprecedented changes in all aspects of society". Furthermore, the report finds that "limiting global warming to 1.5 °C compared with 2 °C would reduce challenging impacts on ecosystems, human health and well-being" and that a 2 °C temperature increase would exacerbate extreme weather, rising sea levels and diminishing Arctic sea ice, coral bleaching, and loss of ecosystems, among other impacts.

SR15 also has modelling that shows that, for global warming to be limited to 1.5 °C, "Global net human-caused emissions of carbon dioxide (CO₂) would need to fall by about 45 percent from 2010 levels by 2030, reaching 'net zero' around 2050." The reduction of emissions by 2030 and its associated changes and challenges, including rapid decarbonisation, was a key focus on much of the reporting which was repeated through the world.

The modern Olympic Games (Olympics; French: Jeux olympiques) are the world's preeminent international sporting events. They feature summer and winter sports competitions in which thousands of athletes from around the world participate in a variety of competitions. The Olympic Games, open to both amateur and professional athletes, involves more than 200 teams, each team representing a sovereign state or territory. By default, the Games generally substitute for any world championships during the year in which they take place (however, each class usually maintains its own records). The Olympics are staged every four years. Since 1994, they have alternated between the Summer and Winter Olympics every two years during the four-year Olympiad.

Their creation was inspired by the ancient Olympic Games, held in Olympia, Greece, from the 8th century BC to the 4th century AD. Baron Pierre de Coubertin founded the International Olympic Committee (IOC) in 1894, leading to the first modern Games in Athens in 1896. The IOC is the governing body of the Olympic Movement, which encompasses all entities and individuals involved in the Olympic Games. The Olympic Charter defines their structure and authority.

International trade is the exchange of capital, goods, and services across international borders or territories because there is a need or want of goods or services. (See: World economy.)

In most countries, such trade represents a significant share of gross domestic product (GDP). While international trade has existed throughout history (for example Uttarapatha, Silk Road, Amber Road, salt roads), its economic, social, and political importance has been on the rise in recent centuries.

Artist's conception of a protoplanetary disk

There is evidence that the formation of the Solar System began about 4.6 billion years ago with the gravitational collapse of a small part of a giant molecular cloud. Most of the collapsing mass collected in the center, forming the Sun, while the rest flattened into a protoplanetary disk out of which the planets, moons, asteroids, and other small Solar System bodies formed.

This model, known as the nebular hypothesis, was first developed in the 18th century by Emanuel Swedenborg, Immanuel Kant, and Pierre-Simon Laplace. Its subsequent development has interwoven a variety of scientific disciplines including astronomy, chemistry, geology, physics, and planetary science. Since the dawn of the Space Age in the 1950s and the discovery of exoplanets in the 1990s, the model has been both challenged and refined to account for new observations. (Full article...)

The Seven Wonders of Wales (Welsh: Saith Rhyfeddod Cymru) is a traditional list of notable landmarks in north Wales, commemorated in an anonymously written rhyme:

The rhyme is usually supposed to have been written sometime in the late 18th or early 19th century by an English visitor to North Wales. The specific number of wonders may have varied over the years: the antiquary Daines Barrington, in a letter written in 1770, refers to Llangollen Bridge as one of the "five wonders of Wales, though like the seven wonders of Dauphiny, they turn out to be no wonders at all out of the Principality".

The northernmost tip of Prins Karls Forland in Forlandet National Park

Svalbard is an Arctic wilderness archipelago comprising the northernmost part of Norway. There are twenty-nine protected natural areas, consisting of seven national parks, six nature reserves, fifteen bird sanctuaries and one geotope protected area. In addition, human traces dating from before 1946 are automatically protected. The protected areas make up 39,800 square kilometers (15,400 sq mi) or 65% of the land area, and 78,000 square kilometers (30,000 sq mi) or 86.5% of the territorial waters. The largest protected areas are Nordaust-Svalbard Nature Reserve and Søraust-Svalbard Nature Reserve, which cover most of the areas east of the main island of Spitsbergen, including the islands of Nordaustlandet, Edgeøya, Barentsøya, Kong Karls Land and Kvitøya. Six of the national parks are located on Spitsbergen. Ten of the bird sanctuaries and the Moffen Nature Reserve are located within national parks. Five of the bird sanctuaries are Ramsar sites and fourteen of the bird sanctuaries are islands. Svalbard is on Norway's tentative list for nomination as a UNESCO World Heritage Site.

The supreme responsibility for conservation lies with the Norwegian Ministry of the Environment, which has delegated the management to the Governor of Svalbard and the Norwegian Directorate for Nature Management. The foundation for conservation was established in the Svalbard Treaty of 1920, and has been further specified in the Svalbard Environmental Act of 2001. The first round of protection took force on 1 July 1973, when most of the current protected areas came into effect. This included the two large nature reserves and three of the national parks. Moffen Nature Reserve was established in 1983, followed by four national parks, three nature reserves and one geotope protection area between 2002 and 2005. (Full article...)

This is a list of the nationally designated protected areas of China. There are many forms of protected areas in China. Based on their relative importance, each type of protected area can be further graded into two to three levels (national, provincial and prefectural/county level). Nevertheless, the highest rank for "pocket nature preserve" (social and mass-based), "no-hunting area", "no-fishing area", "no-logging area", "wild medicinal material resources conservation area", "crop germplasm resources conservation area", "forest tree germplasm resources conservation area" or "source water protection area" is practically restricted to provincial level. The local government at county level is also responsible for the delimitation and declaration of "basic farmland protection area" and "basic grassland".

Take note that many protected areas in China have multiple official designations, and the statutory boundaries of these multi-designated PAs may be identical or may vary one from the other. For instance, the boundaries of Huangshan NSHA coincide with those of the Huangshan NGP, whereas Fujian province's Wuyi Mountains NNR, NSHA and NFP are adjacent to each other. In Heilongjiang, 27,642.14 hectares out of 115,340.27 hectares of Huzhong NFP are intersected with the experiment zone of Huzhong NNR. (Full article...)
