Library of Congress
The Library of Congress is the research library that serves the United States Congress and is the de facto national library of the United States. It is the oldest federal cultural institution in the United States; the Library is housed in three buildings on Capitol Hill in Washington, D. C.. The Library's functions are overseen by the Librarian of Congress, its buildings are maintained by the Architect of the Capitol; the Library of Congress has claimed to be the largest library in the world. Its "collections are universal, not limited by subject, format, or national boundary, include research materials from all parts of the world and in more than 450 languages."The Library of Congress moved to Washington in 1800 after sitting for 11 years in the temporary national capitals in New York City and Philadelphia. The small Congressional Library was housed in the United States Capitol for most of the 19th century until the early 1890s. Most of the original collection had been destroyed by the British in 1814 during the War of 1812, the library sought to restore its collection in 1815.
They bought Thomas Jefferson's entire personal collection of 6,487 books. After a period of slow growth, another fire struck the Library in its Capitol chambers in 1851, again destroying a large amount of the collection, including many of Jefferson's books. After the American Civil War, the Library of Congress grew in both size and importance, which sparked a campaign to purchase replacement copies for volumes, burned; the Library received the right of transference of all copyrighted works to deposit two copies of books, maps and diagrams printed in the United States. It began to build its collections, its development culminated between 1888 and 1894 with the construction of a separate, extensive library building across the street from the Capitol; the Library's primary mission is to research inquiries made by members of Congress, carried out through the Congressional Research Service. The Library is open to the public, although only high-ranking government officials and Library employees may check out books and materials.
James Madison is credited with the idea of creating a congressional library, first making such a proposition in 1783. The Library of Congress was subsequently established April 24, 1800 when President John Adams signed an act of Congress providing for the transfer of the seat of government from Philadelphia to the new capital city of Washington. Part of the legislation appropriated $5,000 "for the purchase of such books as may be necessary for the use of Congress... and for fitting up a suitable apartment for containing them." Books were ordered from London, the collection consisted of 740 books and three maps which were housed in the new United States Capitol. President Thomas Jefferson played an important role in establishing the structure of the Library of Congress. On January 26, 1802, he signed a bill that allowed the president to appoint the Librarian of Congress and establishing a Joint Committee on the Library to regulate and oversee it; the new law extended borrowing privileges to the President and Vice President.
The invading British army burned Washington in August 1814 during the War of 1812 and destroyed the Library of Congress and its collection of 3,000 volumes. These volumes had been left in the Senate wing of the Capitol. One of the few congressional volumes to survive was a government account book of receipts and expenditures for 1810, it was taken as a souvenir by British Admiral George Cockburn, whose family returned it to the United States government in 1940. Within a month, Thomas Jefferson offered to sell his personal library as a replacement. Congress accepted his offer in January 1815; some members of the House of Representatives opposed the outright purchase, including New Hampshire Representative Daniel Webster who wanted to return "all books of an atheistical and immoral tendency." Jefferson had spent 50 years accumulating a wide variety of books in several languages and on subjects such as philosophy, law, architecture, natural sciences, studies of classical Greece and Rome, modern inventions, hot air balloons, submarines, fossils and meteorology.
He had collected books on topics not viewed as part of a legislative library, such as cookbooks. However, he believed, he remarked: I do not know that it contains any branch of science which Congress would wish to exclude from their collection. Jefferson's collection was unique in that it was the working collection of a scholar, not a gentleman's collection for display. With the addition of his collection, the Library of Congress was transformed from a specialist's library to a more general one, his original collection was organized into a scheme based on Francis Bacon's organization of knowledge. He grouped his books into Memory and Imagination, which broke down into 44 more subdivisions; the Library followed Jefferson's organization scheme until the late 19th century, when librarian Herbert Putnam began work on a more flexible Library of Congress Classification structure that now applies to more than 138 million items. In 1851, a fire destroyed two thirds of the Jefferson collection, with only 2,000 books remaining.
By 2008, the Librarians of Congress had found replacements for all but 300 of the works that were in Jefferson's original collection. On December 22, 1851 the largest fire in the Library's history destroyed 35,000 books, about two–thi
The Wall Street Journal
The Wall Street Journal is a U. S. business-focused, English-language international daily newspaper based in New York City. The Journal, along with its Asian and European editions, is published six days a week by Dow Jones & Company, a division of News Corp; the newspaper is published in online. The Journal has been printed continuously since its inception on July 8, 1889, by Charles Dow, Edward Jones, Charles Bergstresser; the Wall Street Journal is one of the largest newspapers in the United States by circulation, with a circulation of about 2.475 million copies as of June 2018, compared with USA Today's 1.7 million. The Journal publishes the luxury news and lifestyle magazine WSJ, launched as a quarterly but expanded to 12 issues as of 2014. An online version was launched in 1996, accessible only to subscribers since it began; the newspaper is notable for its award-winning news coverage, has won 37 Pulitzer Prizes. The editorial pages of the Journal are conservative in their position. The"Journal" editorial board has promoted fringe views on the science of climate change, acid rain, ozone depletion, as well as on the health harms of second-hand smoke and asbestos.
The first products of Dow Jones & Company, the publisher of the Journal, were brief news bulletins, nicknamed "flimsies", hand-delivered throughout the day to traders at the stock exchange in the early 1880s. They were aggregated in a printed daily summary called the Customers' Afternoon Letter. Reporters Charles Dow, Edward Jones, Charles Bergstresser converted this into The Wall Street Journal, published for the first time on July 8, 1889, began delivery of the Dow Jones News Service via telegraph. In 1896, The "Dow Jones Industrial Average" was launched, it was the first of several indices of bond prices on the New York Stock Exchange. In 1899, the Journal's Review & Outlook column, which still runs today, appeared for the first time written by Charles Dow. Journalist Clarence Barron purchased control of the company for US$130,000 in 1902. Barron and his predecessors were credited with creating an atmosphere of fearless, independent financial reporting—a novelty in the early days of business journalism.
In 1921, Barron's, the United States's premier financial weekly, was founded. Barron died in 1928, a year before Black Tuesday, the stock market crash that affected the Great Depression in the United States. Barron's descendants, the Bancroft family, would continue to control the company until 2007; the Journal took its modern shape and prominence in the 1940s, a time of industrial expansion for the United States and its financial institutions in New York. Bernard Kilgore was named managing editor of the paper in 1941, company CEO in 1945 compiling a 25-year career as the head of the Journal. Kilgore was the architect of the paper's iconic front-page design, with its "What's News" digest, its national distribution strategy, which brought the paper's circulation from 33,000 in 1941 to 1.1 million at the time of Kilgore's death in 1967. Under Kilgore, in 1947, the paper won its first Pulitzer Prize for William Henry Grimes's editorials. In 1967, Dow Jones Newswires began a major expansion outside of the United States that put journalists in every major financial center in Europe, Latin America and Africa.
In 1970, Dow Jones bought the Ottaway newspaper chain, which at the time comprised nine dailies and three Sunday newspapers. The name was changed to "Dow Jones Local Media Group".1971 to 1997 brought about a series of launches and joint ventures, including "Factiva", The Wall Street Journal Asia, The Wall Street Journal Europe, the WSJ.com website, Dow Jones Indexes, MarketWatch, "WSJ Weekend Edition". In 2007, News Corp. acquired Dow Jones. WSJ. A luxury lifestyle magazine, was launched in 2008. A complement to the print newspaper, The Wall Street Journal Online, was launched in 1996 and has allowed access only by subscription from the beginning. In 2003, Dow Jones began to integrate reporting of the Journal's print and online subscribers together in Audit Bureau of Circulations statements. In 2007, it was believed to be the largest paid-subscription news site on the Web, with 980,000 paid subscribers. Since online subscribership has fallen, due in part to rising subscription costs, was reported at 400,000 in March 2010.
In May 2008, an annual subscription to the online edition of The Wall Street Journal cost $119 for those who do not have subscriptions to the print edition. By June 2013, the monthly cost for a subscription to the online edition was $22.99, or $275.88 annually, excluding introductory offers. On November 30, 2004, Oasys Mobile and The Wall Street Journal released an app that would allow users to access content from the Wall Street Journal Online via their mobile phones. Many of The Wall Street Journal news stories are available through free online newspapers that subscribe to the Dow Jones syndicate. Pulitzer Prize–winning stories from 1995 are available free on the Pulitzer web site. In September 2005, the Journal launched a weekend edition, delivered to all subscribers, which marked a return to Saturday publication after a lapse of some 50 years; the move was designed in part to attract more consumer advertising. In 2005, the Journal reported a readership profile of about 60 percent top management, an average income of $191,000, an average household net worth of $2.1 million, an average age of 55.
In 2007, the Journal launched a worldwide expansion of its website to include major foreign-language editions. The p
The United Nations is an intergovernmental organization, tasked to maintain international peace and security, develop friendly relations among nations, achieve international co-operation and be a centre for harmonizing the actions of nations. The headquarters of the UN is in Manhattan, New York City, is subject to extraterritoriality. Further main offices are situated in Geneva, Nairobi and The Hague; the organization is financed by voluntary contributions from its member states. Its objectives include maintaining international peace and security, protecting human rights, delivering humanitarian aid, promoting sustainable development and upholding international law; the UN is the largest, most familiar, most internationally represented and most powerful intergovernmental organization in the world. In 24 October 1945, at the end of World War II, the organization was established with the aim of preventing future wars. At its founding, the UN had 51 member states; the UN is the successor of the ineffective League of Nations.
On 25 April 1945, 50 governments met in San Francisco for a conference and started drafting the UN Charter, adopted on 25 June 1945 in the San Francisco Opera House, signed on 26 June 1945 in the Herbst Theatre auditorium in the Veterans War Memorial Building. This charter took effect on 24 October 1945; the UN's mission to preserve world peace was complicated in its early decades during the Cold War between the United States and Soviet Union and their respective allies. Its missions have consisted of unarmed military observers and armed troops with monitoring and confidence-building roles; the organization's membership grew following widespread decolonization which started in the 1960s. Since 80 former colonies had gained independence, including 11 trust territories, which were monitored by the Trusteeship Council. By the 1970s its budget for economic and social development programmes far outstripped its spending on peacekeeping. After the end of the Cold War, the UN shifted and expanded its field operations, undertaking a wide variety of complex tasks.
The UN has six principal organs: the General Assembly. The UN System agencies include the World Bank Group, the World Health Organization, the World Food Programme, UNESCO, UNICEF; the UN's most prominent officer is the Secretary-General, an office held by Portuguese politician and diplomat António Guterres since 1 January 2017. Non-governmental organizations may be granted consultative status with ECOSOC and other agencies to participate in the UN's work; the organization, its officers and its agencies have won many Nobel Peace Prizes. Other evaluations of the UN's effectiveness have been mixed; some commentators believe the organization to be an important force for peace and human development, while others have called the organization ineffective, biased, or corrupt. In the century prior to the UN's creation, several international treaty organizations such as the International Committee of the Red Cross was formed to ensure protection and assistance for victims of armed conflict and strife.
In 1914, a political assassination in Sarajevo set off a chain of events that led to the outbreak of World War I. As more and more young men were sent down into the trenches, influential voices in the United States and Britain began calling for the establishment of a permanent international body to maintain peace in the postwar world. President Woodrow Wilson became a vocal advocate of this concept, in 1918 he included a sketch of the international body in his 14-point proposal to end the war. In November 1918, the Central Powers agreed to an armistice to halt the killing in World War I. Two months the Allies met with Germany and Austria-Hungary at Versailles to hammer out formal peace terms. President Wilson wanted peace, but the United Kingdom and France disagreed, forcing harsh war reparations on their former enemies; the League of Nations was approved, in the summer of 1919 Wilson presented the Treaty of Versailles and the Covenant of the League of Nations to the US Senate for ratification.
On January 10, 1920, the League of Nations formally comes into being when the Covenant of the League of Nations, ratified by 42 nations in 1919, takes effect. However, at some point the League became ineffective when it failed to act against the Japanese invasion of Manchuria as in February 1933, 40 nations voted for Japan to withdraw from Manchuria but Japan voted against it and walked out of the League instead of withdrawing from Manchuria, it failed against the Second Italo-Ethiopian War despite trying to talk to Benito Mussolini as he used the time to send an army to Africa, so the League had a plan for Mussolini to just take a part of Ethiopia, but he ignored the League and invaded Ethiopia, the League tried putting sanctions on Italy, but Italy had conquered Ethiopia and the League had failed. After Italy conquered Ethiopia and other nations left the league, but all of them realised that they began to re-arm as fast as possible. During 1938, Britain and France tried negotiating directly with Hitler but this failed in 1939 when Hitler invaded Czechoslovakia.
When war broke out in 1939, the League closed down and its headquarters in Geneva remained empty throughout the war. The earliest concrete plan for a new world organization began under the aegis of the U. S. State Department in 1939; the text of the "Declaration by United Nations" was drafted at the White House on December 29, 1941, by President Franklin D. Roosevelt, Prime Minister Winston Churchill, Roosevelt aide Harry Hopkins
Quadrant is an Australian literary and cultural journal. Quadrant reviews literature, as well as featuring essays on ideas and topics such as politics, history and the arts, it publishes poetry and short stories. The magazine was founded in Sydney in 1956 by Richard Krygier, a Polish–Jewish refugee, active in social-democrat politics in Europe and James McAuley, a Catholic poet, known for the anti-modernist Ern Malley hoax, it was an initiative of the Australian Committee for Cultural Freedom, the Australian arm of the Congress for Cultural Freedom, an anti-communist advocacy group funded by the CIA. It has had many notable contributors including Les Murray, its literary editor from 1990 to 2019, Peter Ryan, who wrote a column from 1994 to 2015, Heinz Arndt, Sir Garfield Barwick, Frank Brennan, Ian Callinan, Hal Colebatch, Peter Coleman, Sir Zelman Cowen, Anthony Daniels, Joe Dolce, David Flint, Lord Harris of High Cross, Paul Hasluck, Dyson Heydon, Sidney Hook, A.

In the immediate aftermath of the 2017 Manchester Arena bombing Quadrant's online editor Roger Franklin wrote an article titled "The Manchester Bomber's ABC Pals" Referring to the Manchester bombing and Monday night's Q&A television program, the article said, "Had there been a shred of justice, that blast would have detonated in an Ultimo TV studio" and continued, "Unlike those young girls in Manchester, their lives snuffed out before they could begin, none of the panel’s casualties would have represented the slightest reduction in humanity’s intelligence, empathy or honesty." ABC Managing Director Michelle Guthrie called the article a "vicious and offensive attack" and called for the article to "be removed and apologised for". Quadrant editor-in-chief Keith Windschuttle acknowledged that the article was "intemperate" and "a serious error of judgment", he apologised for the offence it had caused; the article was removed from the Quadrant website on 25 May 2017. The magazine holds a conservative stance on social issues.
In October 1992, Dame Leonie Kramer the Chairman of the magazine's Board of Directors, discussed the "deep values" of Quadrant: "the intrinsic value of cultural and intellectual freedom and of inquiry..." "cultural and intellectual freedoms, indeed negative liberties depend upon an abundance of autonomous institutions and an open society..." "political democracy... support of particular democratic institutions, a culture that accepts peaceful and democratic modes of government and change of government..." "liberal democracy, democracy that respects individual liberty... insists that government be limited: by other holders of political and economic resources, by protected private property, by free media, most of all by the rule of law, the restraint and channelling of power by law..." "the virtues, the wisdom, borne by traditions in social and moral life... It has not pretended that traditions have all the answers or should be treated with uncritical reverence... It has, recommended that... long established moral and social practices be treated with respect and caution."
"an economic order in which markets are allowed to work - within the rule of law - as sources of information, as ingredients and supporters of liberty and as facilitators of competitive private enterprise and individual choice..."In March 2008, the magazine was describing itself as sceptical of "unthinking Leftism, or political correctness, its'smelly little orthodoxies'".

Virtual International Authority File
The Virtual International Authority File is an international authority file. It is a joint project of several national libraries and operated by the Online Computer Library Center. Discussion about having a common international authority started in the late 1990s. After a series of failed attempts to come up with a unique common authority file, the new idea was to link existing national authorities; this would present all the benefits of a common file without requiring a large investment of time and expense in the process. The project was initiated by the US Library of Congress, the German National Library and the OCLC on August 6, 2003; the Bibliothèque nationale de France joined the project on October 5, 2007. The project transitioned to being a service of the OCLC on April 4, 2012; the aim is to link the national authority files to a single virtual authority file. In this file, identical records from the different data sets are linked together. A VIAF record receives a standard data number, contains the primary "see" and "see also" records from the original records, refers to the original authority records.
The data are available for research and data exchange and sharing. Reciprocal updating uses the Open Archives Initiative Protocol for Metadata Harvesting protocol; the file numbers are being added to Wikipedia biographical articles and are incorporated into Wikidata. VIAF's clustering algorithm is run every month; as more data are added from participating libraries, clusters of authority records may coalesce or split, leading to some fluctuation in the VIAF identifier of certain authority records.

Intergovernmental Panel on Climate Change
The Intergovernmental Panel on Climate Change is an intergovernmental body of the United Nations, dedicated to providing the world with an objective, scientific view of climate change, its natural and economic impacts and risks, possible response options. It was established in 1988 by the World Meteorological Organization and the United Nations Environment Programme, endorsed by the United Nations General Assembly. Membership is open to all members of the WMO and UN; the IPCC produces reports that contribute to the work of the United Nations Framework Convention on Climate Change, the main international treaty on climate change. The objective of the UNFCCC is to "stabilize greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system"; the IPCC's Fifth Assessment Report was a critical scientific input into the UNFCCC's Paris Agreement in 2015. IPCC reports cover the "scientific and socio-economic information relevant to understanding the scientific basis of risk of human-induced climate change, its potential impacts and options for adaptation and mitigation."
The IPCC does not carry out original research, nor does it monitor climate or related phenomena itself. Rather, it assesses published literature including non-peer-reviewed sources. However, the IPCC can be said to stimulate research in climate science. Chapters of IPCC reports close with sections on limitations and knowledge or research gaps, the announcement of an IPCC special report can catalyse research activity in that area. Thousands of scientists and other experts contribute on a voluntary basis to writing and reviewing reports, which are reviewed by governments. IPCC reports contain a "Summary for Policymakers", subject to line-by-line approval by delegates from all participating governments; this involves the governments of more than 120 countries. The IPCC provides an internationally accepted authority on climate change, producing reports which have the agreement of leading climate scientists and the consensus of participating governments; the 2007 Nobel Peace Prize was shared, between the IPCC and Al Gore.
Following the election of a new Bureau in 2015, the IPCC embarked on its sixth assessment cycle. Besides the Sixth Assessment Report, to be completed in 2022, the IPCC released the Special Report on Global Warming of 1.5 °C in October 2018, will release an update to its 2006 Guidelines for National Greenhouse Gas Inventories—the 2019 Refinement—in May 2019, will deliver two further special reports in 2019: the Special Report on the Ocean and Cryosphere in a Changing Climate, Climate Change and Land. This makes the sixth assessment cycle the most ambitious in the IPCC's 30-year history; the IPCC decided to prepare a special report on cities and climate change in the seventh assessment cycle, held a conference in March 2018 to stimulate research in this area. The IPCC developed from an international scientific body, the Advisory Group on Greenhouse Gases set up in 1985 by the International Council of Scientific Unions, the United Nations Environment Programme, the World Meteorological Organization to provide recommendations based on current research.
This small group of scientists lacked the resources to cover the complex interdisciplinary nature of climate science. The United States Environmental Protection Agency and State Department wanted an international convention to agree restrictions on greenhouse gases, the conservative Reagan Administration was concerned about unrestrained influence from independent scientists or from United Nations bodies including UNEP and the WMO; the U. S. government was the main force in forming the IPCC as an autonomous intergovernmental body in which scientists took part both as experts on the science and as official representatives of their governments, to produce reports which had the firm backing of all the leading scientists worldwide researching the topic, which had to gain consensus agreement from every one of the participating governments. In this way, it was formed as a hybrid between a scientific body and an intergovernmental political organisation; the Intergovernmental Panel on Climate Change assesses peer-reviewed scientific literature and other relevant publications to provide information on the state of knowledge about climate change.
It does not conduct its own original research. It produces comprehensive assessments, reports on special topics, methodologies; the assessments build on previous reports. For example the wording of the reports from the first to the fifth assessment reflects the growing evidence for a changing climate caused by human activity; the IPCC has adopted and published "Principles Governing IPCC Work", which states that the IPCC will assess: the risk of human-induced climate change, its potential impacts, possible options for prevention. This document states that IPCC will do this work by assessing "on a comprehensive, objective and transparent basis the scientific and socio-economic information relevant to understanding the scientific basis" of these topics; the Principles state that "IPCC reports should be neutral with respect to policy, although they may need to deal objectively with scientific and socio-economic factors relevant to the application of particular policies." Korean economist Hoesung Lee has been the chair of the IPCC since 8 October 2015, with the election of the new IPCC Bureau.
Before this election, the IPCC was led by Vice-Chair Ismail El Gizouli, designated acting Chair after the resignation of Rajendra K. Pachauri in February 2015; the previous chairs w
Global warming is a long-term rise in the average temperature of the Earth's climate system, an aspect of climate change shown by temperature measurements and by multiple effects of the warming. Though earlier geological periods experienced episodes of warming, the term refers to the observed and continuing increase in average air and ocean temperatures since 1900 caused by emissions of greenhouse gasses in the modern industrial economy. In the modern context the terms global warming and climate change are used interchangeably, but climate change includes both global warming and its effects, such as changes to precipitation and impacts that differ by region. Many of the observed warming changes since the 1950s are unprecedented in the instrumental temperature record, in historical and paleoclimate proxy records of climate change over thousands to millions of years. In 2013, the Intergovernmental Panel on Climate Change Fifth Assessment Report concluded, "It is likely that human influence has been the dominant cause of the observed warming since the mid-20th century."
The largest human influence has been the emission of greenhouse gases such as carbon dioxide and nitrous oxide. Climate model projections summarized in the report indicated that during the 21st century, the global surface temperature is to rise a further 0.3 to 1.7 °C to 2.6 to 4.8 °C depending on the rate of greenhouse gas emissions and on climate feedback effects. These findings have been recognized by the national science academies of the major industrialized nations and are not disputed by any scientific body of national or international standing. Future climate change effects are expected to include rising sea levels, ocean acidification, regional changes in precipitation, expansion of deserts in the subtropics. Surface temperature increases are greatest in the Arctic, with the continuing retreat of glaciers and sea ice. Predicted regional precipitation effects include more frequent extreme weather events such as heat waves, wildfires, heavy rainfall with floods, heavy snowfall. Effects directly significant to humans are predicted to include the threat to food security from decreasing crop yields, the abandonment of populated areas due to rising sea levels.
Environmental impacts appear to include the extinction or relocation of ecosystems as they adapt to climate change, with coral reefs, mountain ecosystems, Arctic ecosystems most threatened. Because the climate system has a large "inertia" and greenhouse gases will remain in the atmosphere for a long time, climatic changes and their effects will continue to become more pronounced for many centuries if further increases to greenhouse gases stop. Possible societal responses to global warming include mitigation by emissions reduction, adaptation to its effects, possible future climate engineering. Most countries are parties to the United Nations Framework Convention on Climate Change, whose ultimate objective is to prevent dangerous anthropogenic climate change. Parties to the UNFCCC have agreed that deep cuts in emissions are required and that global warming should be limited to well below 2.0 °C compared to pre-industrial levels, with efforts made to limit warming to 1.5 °C. Some scientists call into question climate adaptation feasibility, with higher emissions scenarios, or the two degree temperature target.
Public reactions to global warming and concern about its effects are increasing. A 2015 global survey showed that a median of 54% of respondents consider it "a serious problem", with significant regional differences: Americans and Chinese are among the least concerned. Multiple independently produced datasets confirm that between 1880 and 2012, the global average surface temperature increased by 0.85 °C. Since 1979 the rate of warming has doubled. Climate proxies show the temperature to have been stable over the one or two thousand years before 1850, with regionally varying fluctuations such as the Medieval Warm Period and the Little Ice Age. Although the increase of the average near-surface atmospheric temperature is used to track global warming, over 90% of the additional energy stored in the climate system over the last 50 years has accumulated in the oceans; the rest warmed the continents and the atmosphere. The warming evident in the instrumental temperature record is consistent with a wide range of observations, as documented by many independent scientific groups.
Examples include sea level rise, widespread melting of snow and land ice, increased heat content of the oceans, increased humidity, the earlier timing of spring events, e.g. the flowering of plants. Global warming refers with the amount of warming varying by region. Since 1979, global average land temperatures have increased about twice as fast as global average ocean temperatures; this is due to the larger heat capacity of the oceans and because oceans lose more heat by evaporation. Where greenhouse gas emissions occur does not impact the location of warming because the major greenhouse gases persist long enough to diffuse across the planet, although localized black carbon deposits on snow and ice do contribute to Arctic warming; the Northern Hemisphere and North Pole have heated much faster than the South Pole and Southern Hemisphere. The Northern Hemisphere not only has much more land, its arrangement around the Arctic Ocean has resulted in the maximum surface area flipping from reflective snow and ice cover to ocean and land surfaces that absorb more sunlight.
