"The ongoing COVID-19 pandemic marks the most significant, singular global disruption since World War II, with health, economic, political, and security implications that will ripple for years to come." -Global Trends 2040 (2021) Global Trends 2040-A More Contested World (2021), released by the US National Intelligence Council, is the latest report in its series of reports starting in 1997 about megatrends and the world's future. This report, strongly influenced by the COVID-19 pandemic, paints a bleak picture of the future and describes a contested, fragmented and turbulent world. It specifically discusses the four main trends that will shape tomorrow's world: - Demographics-by 2040, 1.4 billion people will be added mostly in Africa and South Asia. - Economics-increased government debt and concentrated economic power will escalate problems for the poor and middleclass. - Climate-a hotter world will increase water, food, and health insecurity. - Technology-the emergence of new technologies could both solve and cause problems for human life. Students of trends, policymakers, entrepreneurs, academics, journalists and anyone eager for a glimpse into the next decades, will find this report, with colored graphs, essential reading.

Concern about the threat posed by nuclear weapons has preoccupied the United States and presidents of the United States since the beginning of the nuclear era. Nuclear Security draws from papers presented at the 2013 meeting of the American Nuclear Society examining worldwide efforts to control nuclear weapons and ensure the safety of the nuclear enterprise of weapons and reactors against catastrophic accidents. The distinguished contributors, all known for their long-standing interest in getting better control of the threats posed by nuclear weapons and reactors, discuss what we can learn from past successes and failures and attempt to identify the key ingredients for a road ahead that can lead us toward a world free of nuclear weapons. The authors review historical efforts to deal with the challenge of nuclear weapons, with a focus on the momentous arms control negotiations between U.S. president Ronald Reagan and Mikhail Gorbachev. They offer specific recommendations for reducing risks that should be adopted by the nuclear enterprise, both military and civilian, in the United States and abroad. Since the risks posed by the nuclear enterprise are so high, they conclude, no reasonable effort should be spared to ensure safety and security.
