21st-century
The 21st (twenty-first) century is the current century in the ''Anno Domini'' era or Common Era, under the Gregorian calendar. It began on 1 January 2001 ( MMI) and will end on 31 December 2100 ( MMC). Marking the beginning of the 21st century was the rise of a global economy and Third World consumerism, deepening global concern over terrorism after 11 September 2001, terrorist attacks and increased private enterprise. The NATO interventions in Afghanistan and Iraq of the early 2000s and overthrowing several regimes during the Arab Spring of the early 2010s led to mixed outcomes in the Arab world, resulting in several civil wars and political instability. The United States has remained the global superpower, while China is now considered an emerging superpower. In 2017, 49.3% of the world's population lived in "some form of democracy", though only 4.5% lived in "full democracies". The United Nations estimates that by 2050 two thirds of the world's population will be urbanize ...

Emerging Superpower
A potential superpower is a state or a political and economic entity that is speculated to be—or to have the potential to soon become—a superpower. Currently, only the United States fulfills the criteria to be considered a superpower. However, the United States is no longer the only uncontested foremost superpower and the world's sole hyperpower to dominate in every domain (i.e. military, culture, economy, technology, diplomatic). Since the 1990s, China, India, the European Union and Russia have been commonly described as potential superpowers. Japan was formerly considered a potential superpower due to its high economic growth. However, its status as a potential superpower has eroded since the 1990s due to an aging population and economic stagnation. Collectively these potential superpowers, and the United States, comprise 68.0% of global nominal GDP, 62.4% of global GDP (PPP), more than one third of the total land area, and approximately half of the world's popula ...

Rising Sea Level
Globally, sea levels are rising due to human-caused climate change. Between 1901 and 2018, the globally averaged sea level rose by , or 1–2 mm per year on average.IPCC, 2019Summary for Policymakers InIPCC Special Report on the Ocean and Cryosphere in a Changing Climate .-O. Pörtner, D.C. Roberts, V. Masson-Delmotte, P. Zhai, M. Tignor, E. Poloczanska, K. Mintenbeck, A. Alegría, M.  Nicolai, A. Okem, J. Petzold, B. Rama, N.M. Weyer (eds.) Cambridge University Press, Cambridge, UK and New York, NY, USA. https://doi.org/10.1017/9781009157964.001. This rate is accelerating, with sea levels now rising by 3.7 mm per year. Climate scientists expect further acceleration during the 21st century. Climate change heats (and therefore expands) the ocean and melts land-based ice sheets and glaciers. Between 1993 and 2018, the thermal expansion of water contributed 42% to sea level rise; melting of temperate glaciers, 21%; Greenland, 15%; and Antarctica, 8%. Over the next 2000 ...

The World Health Organization (WHO) declared the outbreak a public health emergency of international concern on 30 January 2020, and a pandemic on 11 March 2020. As of , the pandemic had caused more than cases and confirmed deaths, making it one of the deadliest in history. COVID-19 symptoms range from undetectable to deadly, but most commonly include fever, dry cough, and fatigue.

NATO
The North Atlantic Treaty Organization (NATO, ; french: Organisation du traité de l'Atlantique nord, ), also called the North Atlantic Alliance, is an intergovernmental military alliance between 30 member states – 28 European and two North American. Established in the aftermath of World War II, the organization implemented the North Atlantic Treaty, signed in Washington, D.C., on 4 April 1949. NATO is a collective security system: its independent member states agree to defend each other against attacks by third parties. During the Cold War, NATO operated as a check on the perceived threat posed by the Soviet Union. The alliance remained in place after the dissolution of the Soviet Union and has been involved in military operations in the Balkans, the Middle East, South Asia, and Africa. The organization's motto is ''animus in consulendo liber'' (Latin for "a mind unfettered in deliberation"). NATO's main headquarters are located in Brussels, Belgium, while NATO ...

Superpower
A superpower is a state with a dominant position characterized by its extensive ability to exert influence or project power on a global scale. This is done through the combined means of economic, military, technological, political and cultural strength as well as diplomatic and soft power influence. Traditionally, superpowers are preeminent among the great powers. While a great power state is capable of exerting its influence globally, superpowers are states so influential that no significant action can be taken by the global community without first considering the positions of the superpowers on the issue. The term was first applied in 1944 during World War II to the United States, the United Kingdom, and the Soviet Union. During the Cold War, the British Empire dissolved, leaving the United States and the Soviet Union to dominate world affairs. At the end of the Cold War and the dissolution of the Soviet Union in 1991, the United States became the world's sole superpower. ...

September 11 Attacks
The September 11 attacks, commonly known as 9/11, were four coordinated suicide terrorist attacks carried out by al-Qaeda against the United States on Tuesday, September 11, 2001. That morning, nineteen terrorists hijacked four commercial airliners scheduled to travel from the Northeastern United States to California. The hijackers crashed the first two planes into the Twin Towers of the World Trade Center in New York City, and the third plane into the Pentagon (the headquarters of the United States military) in Arlington County, Virginia. The fourth plane was intended to hit a federal government building in Washington, D.C., but crashed in a field following a passenger revolt. The attacks killed nearly 3,000 people and instigated the war on terror. The first impact was that of American Airlines Flight 11. It was crashed into the North Tower of the World Trade Center complex in Lower Manhattan at 8:46 a.m. Seventeen minutes later, at 9:03, the World Trade Center’s S ...

The union has a total area of and an estimated total population of about 447million.

Enlargement Of The European Union
The European Union (EU) has expanded a number of times throughout its history by way of the accession of new member states to the Union. To join the EU, a state needs to fulfil economic and political conditions called the Copenhagen criteria (after the Copenhagen summit in June 1993), which require a stable democratic government that respects the rule of law, and its corresponding freedoms and institutions. According to the Maastricht Treaty, each current member state and the European Parliament must agree to any enlargement. The process of enlargement is sometimes referred to as European integration. This term is also used to refer to the intensification of co-operation between EU member states as national governments allow for the gradual harmonisation of national laws. The EU's predecessor, the European Economic Community,Current Article 1 of the Treaty on European Union reads:"The Union shall be founded on the present Treaty and on the Treaty on the Functioning of the Eu ...

Brexit
Brexit (; a portmanteau of "British exit") was the withdrawal of the United Kingdom (UK) from the European Union (EU) at 23:00 GMT on 31 January 2020 (00:00 1 February 2020 CET).The UK also left the European Atomic Energy Community (EAEC or Euratom). The UK is the only sovereign country to have left the EU or the EC. Greenland left the EC (but became an OTC) on 1 February 1985. The UK had been a member state of the EU or its predecessor the European Communities (EC), sometimes of both at the same time, since 1 January 1973. Following Brexit, EU law and the Court of Justice of the European Union no longer have primacy over British laws, except in select areas in relation to Northern Ireland. The European Union (Withdrawal) Act 2018 retains relevant EU law as domestic law, which the UK can now amend or repeal. Under the terms of the Brexit withdrawal agreement, Northern Ireland continues to participate in the European Single Market in relation to goods, and to be a member o ...
