Climate Security
Climate security refers to the national and international security risks induced, directly or indirectly, by changes in climate patterns. It is a concept that summons the idea that climate-related change amplifies existing risks in society that endangers the security of humans, ecosystems, economy, infrastructure and societies. Climate-related security risks have far-reaching implications for the way the world manages peace and security. Climate actions to adapt and mitigate impacts can also have a negative effect on human security if mishandled. Climate change has the potential to exacerbate existing tensions or create new ones – serving as a threat multiplier. It can be a catalyst for violent conflict and a threat to international security. A meta-analysis of over 50 quantitative studies that examine the link between climate and conflict found that "for each 1 standard deviation (1σ) change in climate toward warmer temperatures or more extreme rainfall, median estimates in ...

Energy Security
Energy security is the association between national security and the availability of natural resources for energy consumption. Access to (relatively) cheap energy has become essential to the functioning of modern economies. However, the uneven distribution of energy supplies among countries has led to significant vulnerabilities. International energy relations have contributed to the globalization of the world leading to energy security and energy vulnerability at the same time. Renewable resources exist worldwide across every biome except the North and South Poles (only nuclear (and wind in the winter) is feasible), in contrast to fossil fuels, which are concentrated in a limited number of countries. Nations don't switch from unpredictable fossil fuels to renewables overnight. It is a long, continuous process. Rapid deployment of renewable energy, increased energy efficiency, and diversification of energy sources, energy stores, and types of energy machines can use all ...

Greenhouse Gas Emissions
Greenhouse gas emissions from human activities strengthen the greenhouse effect, contributing to climate change. Most is carbon dioxide from burning fossil fuels: coal, oil, and natural gas. The largest emitters include coal in China and large oil and gas companies, many state-owned by OPEC and Russia. Human-caused emissions have increased atmospheric carbon dioxide by about 50% over pre-industrial levels. The growing levels of emissions have varied, but it was consistent among all greenhouse gases (GHG). Emissions in the 2010s averaged 56 billion tons a year, higher than ever before. Electricity generation and transport are major emitters; the largest single source, according to the United States Environmental Protection Agency, is transportation, accounting for 27% of all USA greenhouse gas emissions. Deforestation and other changes in land use also emit carbon dioxide and methane. The largest source of anthropogenic methane emissions is agriculture, closely followed by ...

United States Department Of Defense
The United States Department of Defense (DoD, USDOD or DOD) is an executive branch department of the federal government charged with coordinating and supervising all agencies and functions of the government directly related to national security and the United States Armed Forces. The DoD is the largest employer in the world, with over 1.34 million active-duty service members (soldiers, marines, sailors, airmen, and guardians) as of June 2022. The DoD also maintains over 778,000 National Guard and reservists, and over 747,000 civilians bringing the total to over 2.87 million employees. Headquartered at the Pentagon in Arlington, Virginia, just outside Washington, D.C., the DoD's stated mission is to provide "the military forces needed to deter war and ensure our nation's security". The Department of Defense is headed by the secretary of defense, a cabinet-level head who reports directly to the president of the United States. Beneath the Department of Defense are th ...

The Pentagon
The Pentagon is the headquarters building of the United States Department of Defense. It was constructed on an accelerated schedule during World War II. As a symbol of the U.S. military, the phrase ''The Pentagon'' is often used as a metonym for the Department of Defense and its leadership. Located in Arlington County, Virginia, across the Potomac River from Washington, D.C., the building was designed by American architect George Bergstrom and built by contractor John McShain. Ground was broken on 11 September 1941, and the building was dedicated on 15 January 1943. General Brehon Somervell provided the major impetus to gain Congressional approval for the project; Colonel Leslie Groves was responsible for overseeing the project for the U.S. Army Corps of Engineers, which supervised it. The Pentagon is the world's largest office building, with about of floor space, of which are used as offices. Some 23,000 military and civilian employees, and another 3,000 non-defense sup ...

Quadrennial Defense Review
The Quadrennial Defense Review (QDR) was a study by the United States Department of Defense that analyzes strategic objectives and potential military threats. The ''Quadrennial Defense Review Report'' was the main public document describing the United States' military doctrine. In 2018, the QDR was replaced by the National Defense Strategy (February 2018). As stipulated in the 1997 National Defense Authorization Act (NDAA), the QDR is to be conducted every four years. , five QDR's have been published. The first in 1997, then September 2001, February 2006, February 2010, and most recently March 2014. Starting with the 2006 QDR, the publication is required to coincide with the issuance of the next year's budget request. The congressionally mandated Quadrennial Defense Review (QDR) directs DoD to undertake a wide-ranging review of strategy, programs, and resources. Specifically, the QDR is expected to delineate a national defense strategy consistent with the most recent National Secur ...

JASON (advisory Group)
JASON is an independent group of elite scientists which advises the United States government on matters of science and technology, mostly of a sensitive nature. The group was created in the aftermath of the Sputnik launch as a way to reinvigorate the idea of having the nation's preeminent scientists help the government with defense problems, similar to the way that scientists helped in World War II but with a new and younger generation. It was established in 1960 and has somewhere between 30 and 60 members. Its work first gained public notoriety as the source of the Vietnam War's McNamara Line electronic barrier. Although most of its research is military-focused, JASON also produced early work on the science of global warming and acid rain. Current unclassified research interests include health informatics, cyberwarfare, and renewable energy. Activities For administrative purposes, JASON's activities are run through the MITRE Corporation, a not-for-profit corporation in McLean, V ...

Human Security
Human security is a paradigm for understanding global vulnerabilities whose proponents challenges the traditional notion of national security through military security by arguing that the proper referent for security should be at the human rather than national level. Human security reveals a people-centred and multi-disciplinary understanding of security which involves a number of research fields, including development studies, international relations, strategic studies, and human rights. The United Nations Development Programme's 1994 Human Development Report is considered a milestone publication in the field of human security, with its argument that ensuring " freedom from want" and "freedom from fear" for all persons is the best path to tackle the problem of global insecurity.United Nations Development Programme (1994): Human Development Report Critics of the concept argue that its vagueness undermines its effectiveness, that it has become little more than a vehicle for activist ...

Environmental Security
Environmental security examines threats posed by environmental events and trends to individuals, communities or nations. It may focus on the impact of human conflict and international relations on the environment, or on how environmental problems cross state borders. General The Millennium Project assessed definitions of environmental security and created a synthesis definition: Environmental security is environmental viability for life support, with three sub-elements: *preventing or repairing military damage to the environment, *preventing or responding to environmentally caused conflicts, and *protecting the environment due to its inherent moral value. It considers the abilities of individuals, communities or nations to cope with environmental risks, changes or conflicts, or limited natural resources. For example, climate change can be viewed a threat to environmental security (see the article climate security for more nuance to the discussion.) Human activity impacts CO2 emi ...

Power Outage
A power outage (also called a powercut, a power out, a power failure, a power blackout, a power loss, or a blackout) is the loss of the electrical power network supply to an end user. There are many causes of power failures in an electricity network. Examples of these causes include faults at power stations, damage to electric transmission lines, substations or other parts of the distribution system, a short circuit, cascading failure, fuse or circuit breaker operation. Power failures are particularly critical at sites where the environment and public safety are at risk. Institutions such as hospitals, sewage treatment plants, and mines will usually have backup power sources such as standby generators, which will automatically start up when electrical power is lost. Other critical systems, such as telecommunication, are also required to have emergency power. The battery room of a telephone exchange usually has arrays of lead–acid batteries for backup and also a socket ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Price Shock
In economics, a shock is an unexpected or unpredictable event that affects an economy, either positively or negatively. Technically, it is an unpredictable change in exogenous factors—that is, factors unexplained by an economic model—which may influence endogenous economic variables. The response of economic variables, such as GDP and employment, at the time of the shock and at subsequent times, is measured by an impulse response function. Types of shocks A technology shock is the kind resulting from a technological development that affects productivity. If the shock is due to constrained supply, it is termed a supply shock and usually results in price increases for a particular product. Supply shocks can be produced when accidents or disasters occur. The 2008 Western Australian gas crisis resulting from a pipeline explosion at Varanus Island is one example. A demand shock is a sudden change of the pattern of private expenditure, especially of consumption spendin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Famine
A famine is a widespread scarcity of food, caused by several factors including war, natural disasters, crop failure, Demographic trap, population imbalance, widespread poverty, an Financial crisis, economic catastrophe or government policies. This phenomenon is usually accompanied or followed by regional malnutrition, starvation, epidemic, and increased death, mortality. Every inhabited continent in the world has experienced a period of famine throughout history. In the 19th and 20th century, generally characterized Southeast and South Asia, as well as Eastern and Central Europe, in terms of having suffered most number of deaths from famine. The numbers dying from famine began to fall sharply from the 2000s. Since 2010, Africa has been the most affected continent of famine in the world. Definitions According to the United Nations World Food Programme, famine is declared when malnutrition is widespread, and when people have started dying of starvation through lack of access to suf ...
