Answers
It was a long hurtful century and by the end of the century, more technological advances had been made than in all of preceding history. Communications and information technology, transportation technology, and medical advances had radically altered daily lives. Europe appeared to be at a sustainable peace for the first time in recorded history. The people of the Indian subcontinent, a sixth of the world population at the end of the century, had attained an indigenous independence for the first time in centuries. China, an ancient nation comprising a fifth of the world population, was finally open to the world in a new and powerful synthesis of west and east, creating a new state after the near-complete destruction of the old cultural order. With the end of colonialism and the Cold War, nearly a billion people in Africa were left with truly independent new nation states, some cut from whole cloth, standing up after centuries of foreign domination.[259]
The geographic distribution of surface warming during the 21st century calculated by the Had CM3 climate model if a business as usual scenario is assumed for economic growth and greenhouse gas emissions. In this figure, the globally averaged warming corresponds to 3.0 °C (5.4 °F).
The world was undergoing its second major period of globalization; the first, which started in the 19th century, having been terminated by World War I.[260] Since the US was in a position of almost unchallenged domination, a major part of the process was Americanization.[261] This led to anti-Western and anti-American feelings in parts of the world, especially the Middle East.[262] The influence of China and India was also rising, as the world's largest populations, long marginalized by the West and by their own rulers, were rapidly integrating with the world economy.[263]
However, several problems faced the world. The gap between rich and poor nations continued to widen. Some said that this problem could not be fixed, that there was a set amount of wealth and it could only be shared by so many. Others said that the powerful nations with large economies were not doing enough to help improve the rapidly evolving economies of the Third World. However, developing countries faced many challenges, including the scale of the task to be surmounted, rapidly growing populations, and the need to protect the environment and the cost that goes along with it.
Terrorism, dictatorship, and the spread of nuclear weapons were other issues requiring attention. The world was still blighted by small-scale wars and other violent conflicts, fueled by competition over resources and by ethnic conflicts. Despots such as Kim Jong-il of North Korea continued to lead their nations toward the development of nuclear weapons.[264]
Disease threatened to destabilize many regions of the world. New viruses such as SARS and West Nile continued to spread.[265][266] In poor nations, malaria and other diseases affected the majority of the population. Millions were infected with HIV, the virus which causes AIDS. The virus was becoming an epidemic in southern Africa.[267]
Perhaps most importantly, it was speculated that in the long term, environmental problems threatened the planet's livability. The most serious problem was global warming, which was predicted to frequently flood coastal areas, due to human-caused emission of greenhouse gases, particularly carbon dioxide produced by the burning of fossil fuels.[268] This prompted many nations to negotiate and sign the Kyoto treaty, which set mandatory limits on carbon dioxide emissions.[269]
The celebration of the ending of the 20th century and the beginning of the 21st century was at New Year's Day, 2000
