119-857: The High Altitude Warfare School ( HAWS ) is a defence service training and research establishment of the Indian Army . In 1948, the Indian Army established a ski school in Gulmarg that later became the High Altitude Warfare School, which specialises in snow–craft and winter warfare. It is located in an area which is prone to avalanches. Selected soldiers from the US, UK, Germany and other countries visit regularly for specialist training. The birth of High Altitude Warfare School (HAWS) of Indian Army in 1948 can be directly attributed to

Responding to this PIL, Delhi Police told the SC in July 2019 that nearly 500 illegal Bangladeshi immigrants have been deported in the preceding 28 months. There are estimated 600,000 to 700,000 illegal Bangladeshi and Rohingya immigrants in National Capital Region (NCR) region specially in
357-492: A sovereign state , including its citizens , economy , and institutions , which is regarded as a duty of government . Originally conceived as protection against military attack , national security is widely understood to include also non-military dimensions, such as the security from terrorism , minimization of crime , economic security , energy security , environmental security , food security , and cyber-security . Similarly, national security risks include, in addition to
476-562: A broader sense also includes previous long-term changes to Earth's climate. The current rise in global temperatures is driven by human activities , especially fossil fuel burning since the Industrial Revolution . Fossil fuel use, deforestation , and some agricultural and industrial practices release greenhouse gases . These gases absorb some of the heat that the Earth radiates after it warms from sunlight , warming
595-590: A decadal timescale. Other changes are caused by an imbalance of energy from external forcings . Examples of these include changes in the concentrations of greenhouse gases , solar luminosity , volcanic eruptions, and variations in the Earth's orbit around the Sun. To determine the human contribution to climate change, unique "fingerprints" for all potential causes are developed and compared with both observed patterns and known internal climate variability . For example, solar forcing—whose fingerprint involves warming
714-542: A lot of light to being dark after the ice has melted, they start absorbing more heat . Local black carbon deposits on snow and ice also contribute to Arctic warming. Arctic surface temperatures are increasing between three and four times faster than in the rest of the world. Melting of ice sheets near the poles weakens both the Atlantic and the Antarctic limb of thermohaline circulation , which further changes
833-412: A marked increase in temperature. Ongoing changes in climate have had no precedent for several thousand years. Multiple independent datasets all show worldwide increases in surface temperature, at a rate of around 0.2 °C per decade. The 2014–2023 decade warmed to an average 1.19 °C [1.06–1.30 °C] compared to the pre-industrial baseline (1850–1900). Not every single year was warmer than
952-408: A physical climate model. These models simulate how population, economic growth , and energy use affect—and interact with—the physical climate. With this information, these models can produce scenarios of future greenhouse gas emissions. This is then used as input for physical climate models and carbon cycle models to predict how atmospheric concentrations of greenhouse gases might change. Depending on
1071-584: A powerful phrase to invoke against diverse threats to interests of the state, such as domestic concerns. The notion that national security encompasses more than just military security was present, though understated, from the beginning. The Act established the National Security Council so as to "advise the President on the integration of domestic, military and foreign policies relating to national security". The act establishes, within
1190-461: A result of climate change. Global sea level is rising as a consequence of thermal expansion and the melting of glaciers and ice sheets . Sea level rise has increased over time, reaching 4.8 cm per decade between 2014 and 2023. Over the 21st century, the IPCC projects 32–62 cm of sea level rise under a low emission scenario, 44–76 cm under an intermediate one and 65–101 cm under
1309-474: A result. The World Health Organization calls climate change one of the biggest threats to global health in the 21st century. Societies and ecosystems will experience more severe risks without action to limit warming . Adapting to climate change through efforts like flood control measures or drought-resistant crops partially reduces climate change risks, although some limits to adaptation have already been reached. Poorer communities are responsible for

Many climate change impacts have been observed in the first decades of the 21st century, with 2023 the warmest on record at +1.48 °C (2.66 °F) since regular tracking began in 1850. Additional warming will increase these impacts and can trigger tipping points , such as melting all of
1547-703: A state is at peace. National security ideology as taught by the US Army School of the Americas to military personnel was vital in causing the military coup of 1964 in Brazil and the 1976 one in Argentina. The military dictatorships were installed on the claim by the military that Leftists were an existential threat to the national interests. China's military is the People's Liberation Army (PLA). The military
1666-548: A very high emission scenario. Marine ice sheet instability processes in Antarctica may add substantially to these values, including the possibility of a 2-meter sea level rise by 2100 under high emissions. Climate change has led to decades of shrinking and thinning of the Arctic sea ice . While ice-free summers are expected to be rare at 1.5 °C degrees of warming, they are set to occur once every three to ten years at
1785-519: A warming level of 2 °C. Higher atmospheric CO 2 concentrations cause more CO 2 to dissolve in the oceans, which is making them more acidic . Because oxygen is less soluble in warmer water, its concentrations in the ocean are decreasing , and dead zones are expanding. Greater degrees of global warming increase the risk of passing through ' tipping points '—thresholds beyond which certain major impacts can no longer be avoided even if temperatures return to their previous state. For instance,
1904-402: Is also important since most of the countries in the world are developing and dependent on agriculture and agriculture gets affected largely due to climate change. This effect affects the economy of the nation, which in turn affects national security. The scope and nature of environmental threats to national security and strategies to engage them are a subject of debate. Romm (1993) classifies
2023-564: Is an estimated total sea level rise of 2.3 metres per degree Celsius (4.2 ft/°F) after 2000 years. Oceanic CO 2 uptake is slow enough that ocean acidification will also continue for hundreds to thousands of years. Deep oceans (below 2,000 metres (6,600 ft)) are also already committed to losing over 10% of their dissolved oxygen by the warming which occurred to date. Further, the West Antarctic ice sheet appears committed to practically irreversible melting, which would increase
2142-534: Is associated primarily with managing physical threats and with the military capabilities used for doing so. That is, national security is often understood as the capacity of a nation to mobilise military forces to guarantee its borders and to deter or successfully defend against physical threats including military aggression and attacks by non-state actors , such as terrorism . Most states, such as South Africa and Sweden, configure their military forces mainly for territorial defence; others, such as France, Russia,

2380-711: Is determined by modelling the carbon cycle and climate sensitivity to greenhouse gases. According to UNEP , global warming can be kept below 1.5 °C with a 50% chance if emissions after 2023 do not exceed 200 gigatonnes of CO 2 . This corresponds to around 4 years of current emissions. To stay under 2.0 °C, the carbon budget is 900 gigatonnes of CO 2 , or 16 years of current emissions. The climate system experiences various cycles on its own which can last for years, decades or even centuries. For example, El Niño events cause short-term spikes in surface temperature while La Niña events cause short term cooling. Their relative frequency can affect global temperature trends on
2499-399: Is independent of where greenhouse gases are emitted, because the gases persist long enough to diffuse across the planet. Since the pre-industrial period, the average surface temperature over land regions has increased almost twice as fast as the global average surface temperature. This is because oceans lose more heat by evaporation and oceans can store a lot of heat . The thermal energy in

One such example is the use of Stuxnet by the US and Israel against the Iranian nuclear programme Barry Buzan , Ole Wæver , Jaap de Wilde and others have argued that national security depends on political security : the stability of the social order. Others, such as Paul Rogers, have added that the equitability of
2737-450: Is primarily attributed to sulfate aerosols produced by the combustion of fossil fuels with heavy sulfur concentrations like coal and bunker fuel . Smaller contributions come from black carbon (from combustion of fossil fuels and biomass), and from dust. Globally, aerosols have been declining since 1990 due to pollution controls, meaning that they no longer mask greenhouse gas warming as much. Aerosols also have indirect effects on
2856-444: Is radiating into space. Warming reduces average snow cover and forces the retreat of glaciers . At the same time, warming also causes greater evaporation from the oceans , leading to more atmospheric humidity , more and heavier precipitation . Plants are flowering earlier in spring, and thousands of animal species have been permanently moving to cooler areas. Different regions of the world warm at different rates . The pattern
2975-516: Is shaped by feedbacks, which either amplify or dampen the change. Self-reinforcing or positive feedbacks increase the response, while balancing or negative feedbacks reduce it. The main reinforcing feedbacks are the water-vapour feedback , the ice–albedo feedback , and the net effect of clouds. The primary balancing mechanism is radiative cooling , as Earth's surface gives off more heat to space in response to rising temperature. In addition to temperature feedbacks, there are feedbacks in

HAWS is the nodal instructional facility for specialised training and dissemination of approved doctrines in mountain, high altitude and snow warfare. The training programs at HAWS are open to personnel of the armed forces of friendly countries. HAWS also trains Indian Armed Forces personnel for winter sports such as snowboarding, alpine skiing and Nordic skiing. The school recently added facilities to allow

The Ministry of State Security was established in 1983 to ensure "the security of the state through effective measures against enemy agents, spies, and counterrevolutionary activities designed to sabotage or overthrow China's socialist system." For Schengen area some parts of national security and external border control are enforced by Frontex according to
3332-407: Is the major reason why different climate models project different magnitudes of warming for a given amount of emissions. A climate model is a representation of the physical, chemical and biological processes that affect the climate system. Models include natural processes like changes in the Earth's orbit, historical changes in the Sun's activity, and volcanic forcing. Models are used to estimate
3451-436: Is the subject of debate. Some argue that the principal beneficiary of national security policy should be the nation state itself, which should centre its strategy on protective and coercive capabilities in order to safeguard itself in a hostile environment (and potentially to project that power into its environment, and dominate it to the point of strategic supremacy ). Others argue that security depends principally on building
3570-562: Is the urgent need to protect valuables such as these which legitimizes and makes essential the role of national security. To address the institutionalisation of new bureaucracies and government practices in the post–World War II period in the U.S., the culture of semi-permanent military mobilisation joined the National Security Council (NSC), the Central Intelligence Agency (CIA), the Department of Defense (DoD), and
3689-417: Is unclear. A related phenomenon driven by climate change is woody plant encroachment , affecting up to 500 million hectares globally. Climate change has contributed to the expansion of drier climate zones, such as the expansion of deserts in the subtropics . The size and speed of global warming is making abrupt changes in ecosystems more likely. Overall, it is expected that climate change will result in

In larger countries, strategies for economic security expect to access resources and markets in other countries and to protect their own markets at home. Developing countries may be less secure than economically advanced states due to high rates of unemployment and underpaid work. Environmental security, also known as ecological security, refers to

Critical infrastructure is vital for the essential functioning of a country. Incidental or deliberate damage can have a serious impact on the economy and essential services. Some of the threats to infrastructure include: Computer security , also known as cybersecurity or IT security, refers to
4165-661: The Earth's energy budget . Sulfate aerosols act as cloud condensation nuclei and lead to clouds that have more and smaller cloud droplets. These clouds reflect solar radiation more efficiently than clouds with fewer and larger droplets. They also reduce the growth of raindrops , which makes clouds more reflective to incoming sunlight. Indirect effects of aerosols are the largest uncertainty in radiative forcing . While aerosols typically limit global warming by reflecting sunlight, black carbon in soot that falls on snow or ice can contribute to global warming. Not only does this increase
4284-573: The Greenland ice sheet is already melting, but if global warming reaches levels between 1.7 °C and 2.3 °C, its melting will continue until it fully disappears. If the warming is later reduced to 1.5 °C or less, it will still lose a lot more ice than if the warming was never allowed to reach the threshold in the first place. While the ice sheets would melt over millennia, other tipping points would occur faster and give societies less time to respond. The collapse of major ocean currents like
4403-840: The Greenland ice sheet . Under the 2015 Paris Agreement , nations collectively agreed to keep warming "well under 2 °C". However, with pledges made under the Agreement, global warming would still reach about 2.8 °C (5.0 °F) by the end of the century. Limiting warming to 1.5 °C would require halving emissions by 2030 and achieving net-zero emissions by 2050. Fossil fuel use can be phased out by conserving energy and switching to energy sources that do not produce significant carbon pollution. These energy sources include wind , solar , hydro , and nuclear power . Cleanly generated electricity can replace fossil fuels for powering transportation , heating buildings , and running industrial processes. Carbon can also be removed from
4522-635: The Industrial Revolution , naturally-occurring amounts of greenhouse gases caused the air near the surface to be about 33 °C warmer than it would have been in their absence. Human activity since the Industrial Revolution, mainly extracting and burning fossil fuels ( coal , oil , and natural gas ), has increased the amount of greenhouse gases in the atmosphere. In 2022, the concentrations of CO 2 and methane had increased by about 50% and 164%, respectively, since 1750. These CO 2 levels are higher than they have been at any time during

By 2100, 50% to 75% of the global population would live in such areas. While total crop yields have been increasing in the past 50 years due to agricultural improvements, climate change has already decreased
5236-414: The carbon cycle . While plants on land and in the ocean absorb most excess emissions of CO 2 every year, that CO 2 is returned to the atmosphere when biological matter is digested, burns, or decays. Land-surface carbon sink processes, such as carbon fixation in the soil and photosynthesis, remove about 29% of annual global CO 2 emissions. The ocean has absorbed 20 to 30% of emitted CO 2 over

Infrastructure security seeks to limit vulnerability of these structures and systems to sabotage , terrorism , and contamination . Many countries have established government agencies to directly manage the security of critical infrastructure, usually, through the Ministry of Interior/Home Affairs, dedicated security agencies to protect facilities such as United States Federal Protective Service , and also dedicated transport police such as
5593-971: The extinction of many species. The oceans have heated more slowly than the land, but plants and animals in the ocean have migrated towards the colder poles faster than species on land. Just as on land, heat waves in the ocean occur more frequently due to climate change, harming a wide range of organisms such as corals, kelp , and seabirds . Ocean acidification makes it harder for marine calcifying organisms such as mussels , barnacles and corals to produce shells and skeletons ; and heatwaves have bleached coral reefs . Harmful algal blooms enhanced by climate change and eutrophication lower oxygen levels, disrupt food webs and cause great loss of marine life. Coastal ecosystems are under particular stress. Almost half of global wetlands have disappeared due to climate change and other human impacts. Plants have come under increased stress from damage by insects. The effects of climate change are impacting humans everywhere in

5950-405: The 18th century and 1970 there was little net warming, as the warming impact of greenhouse gas emissions was offset by cooling from sulfur dioxide emissions. Sulfur dioxide causes acid rain , but it also produces sulfate aerosols in the atmosphere, which reflect sunlight and cause global dimming . After 1970, the increasing accumulation of greenhouse gases and controls on sulfur pollution led to

#17327724946526188-500: The 1980s, the terms global warming and climate change became more common, often being used interchangeably. Scientifically, global warming refers only to increased surface warming, while climate change describes both global warming and its effects on Earth's climate system , such as precipitation changes. Climate change can also be used more broadly to include changes to the climate that have happened throughout Earth's history. Global warming —used as early as 1975 —became

These include ocean heating , ocean acidification and sea level rise . Climate change threatens people with increased flooding , extreme heat, increased food and water scarcity, more disease, and economic loss . Human migration and conflict can also be
6426-435: The Arctic is another major feedback, this reduces the reflectivity of the Earth's surface in the region and accelerates Arctic warming . This additional warming also contributes to permafrost thawing, which releases methane and CO 2 into the atmosphere. Around half of human-caused CO 2 emissions have been absorbed by land plants and by the oceans. This fraction is not static and if future CO 2 emissions decrease,
6545-545: The CO 2 released by the chemical reactions for making cement , steel , aluminum , and fertilizer . Methane emissions come from livestock , manure, rice cultivation , landfills, wastewater, and coal mining , as well as oil and gas extraction . Nitrous oxide emissions largely come from the microbial decomposition of fertilizer . While methane only lasts in the atmosphere for an average of 12 years, CO 2 lasts much longer. The Earth's surface absorbs CO 2 as part of
6664-604: The Earth will be able to absorb up to around 70%. If they increase substantially, it'll still absorb more carbon than now, but the overall fraction will decrease to below 40%. This is because climate change increases droughts and heat waves that eventually inhibit plant growth on land, and soils will release more carbon from dead plants when they are warmer . The rate at which oceans absorb atmospheric carbon will be lowered as they become more acidic and experience changes in thermohaline circulation and phytoplankton distribution. Uncertainty over feedbacks, particularly cloud cover,

9163-551: The climate cycled through ice ages . One of the hotter periods was the Last Interglacial , around 125,000 years ago, where temperatures were between 0.5 °C and 1.5 °C warmer than before the start of global warming. This period saw sea levels 5 to 10 metres higher than today. The most recent glacial maximum 20,000 years ago was some 5–7 °C colder. This period has sea levels that were over 125 metres (410 ft) lower than today. Temperatures stabilized in
9282-469: The conditions in which equitable relationships between nations can develop, partly by reducing antagonism between actors, ensuring that fundamental needs can be met, and also that differences of interest can be negotiated effectively. In the UK, for example, Malcolm Chalmers argued in 2015 that the heart of the UK's approach should be support for the Western strategic military alliance led through NATO by
9401-566: The council take place in the Presidential Administration Building . The council was created by the provision of Supreme Council of Ukraine #1658-12 on October 11, 1991. It was defined as the highest state body of collegiate governing on matters of defence and security of Ukraine with the following goals: The primary body responsible for coordinating national security policy in the UK is the National Security Council (United Kingdom) which helps produce and enact
9520-684: The current interglacial period beginning 11,700 years ago . This period also saw the start of agriculture. Historical patterns of warming and cooling, like the Medieval Warm Period and the Little Ice Age , did not occur at the same time across different regions. Temperatures may have reached as high as those of the late 20th century in a limited set of regions. Climate information for that period comes from climate proxies , such as trees and ice cores . Around 1850 thermometer records began to provide global coverage. Between
9639-403: The degree of warming future emissions will cause when accounting for the strength of climate feedbacks . Models also predict the circulation of the oceans, the annual cycle of the seasons, and the flows of carbon between the land surface and the atmosphere. The physical realism of models is tested by examining their ability to simulate current or past climates. Past models have underestimated
9758-427: The destroyed trees release CO 2 , and are not replaced by new trees, removing that carbon sink . Between 2001 and 2018, 27% of deforestation was from permanent clearing to enable agricultural expansion for crops and livestock. Another 24% has been lost to temporary clearing under the shifting cultivation agricultural systems. 26% was due to logging for wood and derived products, and wildfires have accounted for
9877-401: The distribution of heat and precipitation around the globe. The World Meteorological Organization estimates there is an 80% chance that global temperatures will exceed 1.5 °C warming for at least one year between 2024 and 2028. The chance of the 5-year average being above 1.5 °C is almost half. The IPCC expects the 20-year average global temperature to exceed +1.5 °C in
9996-473: The districts of Gurugram , Faridabad , and Nuh ( Mewat region), as well as interior villages of Bhiwani and Hisar . Most of them are Muslims who have acquired fake Hindu identity, and under questioning, they pretend to be from West Bengal. In September 2019, the Chief Minister of Haryana , Manohar Lal Khattar announced the implementation of NRC for Haryana by setting up a legal framework under
10115-444: The dominant direct influence on temperature from land use change. Thus, land use change to date is estimated to have a slight cooling effect. Air pollution, in the form of aerosols, affects the climate on a large scale. Aerosols scatter and absorb solar radiation. From 1961 to 1990, a gradual reduction in the amount of sunlight reaching the Earth's surface was observed. This phenomenon is popularly known as global dimming , and
10234-610: The early 2030s. The IPCC Sixth Assessment Report (2021) included projections that by 2100 global warming is very likely to reach 1.0–1.8 °C under a scenario with very low emissions of greenhouse gases , 2.1–3.5 °C under an intermediate emissions scenario , or 3.3–5.7 °C under a very high emissions scenario . The warming will continue past 2100 in the intermediate and high emission scenarios, with future projections of global surface temperatures by year 2300 being similar to millions of years ago. The remaining carbon budget for staying beneath certain temperature increases
10353-466: The effects of warfare on civilians and civil infrastructure . This has led to a dialectical struggle, particularly in liberal democracies , between government authority and the rights and freedoms of the general public. Even where the exercise of national security is subject to good governance , and the rule of law , a risk remains that the term national security may become a pretext for suppressing unfavorable political and social views . In
10472-430: The entire atmosphere—is ruled out because only the lower atmosphere has warmed. Atmospheric aerosols produce a smaller, cooling effect. Other drivers, such as changes in albedo , are less impactful. Greenhouse gases are transparent to sunlight , and thus allow it to pass through the atmosphere to heat the Earth's surface. The Earth radiates it as heat , and greenhouse gases absorb a portion of it. This absorption slows
10591-609: The event of emergence of negative trends towards the creation of potential or real threats to national interests." The primary body responsible for coordinating national security policy in Ukraine is the National Security and Defense Council of Ukraine . It is an advisory state agency to the President of Ukraine , tasked with developing a policy of national security on domestic and international matters. All sessions of
10710-487: The former judge of the Punjab and Haryana High Court, Justice HS Bhalla for updating NRC which will help in weeding out these illegal immigrants. In the years 1997 and 2000, Russia adopted documents titled "National Security Concept" that described Russia's global position, the country's interests, listed threats to national security, and described the means to counter those threats. In 2009, these documents were superseded by
10829-604: The global climate system has grown with only brief pauses since at least 1970, and over 90% of this extra energy has been stored in the ocean . The rest has heated the atmosphere , melted ice, and warmed the continents. The Northern Hemisphere and the North Pole have warmed much faster than the South Pole and Southern Hemisphere . The Northern Hemisphere not only has much more land, but also more seasonal snow cover and sea ice . As these surfaces flip from reflecting
10948-529: The integrity of ecosystems and the biosphere , particularly in relation to their capacity to sustain a diversity of life-forms (including human life). The security of ecosystems has attracted greater attention as the impact of ecological damage by humans has grown. The degradation of ecosystems, including topsoil erosion , deforestation , biodiversity loss , and climate change , affect economic security and can precipitate mass migration , leading to increased pressure on resources elsewhere. Ecological security
11067-409: The international order is equally vital. Hence, political security depends on the rule of international law (including the laws of war ), the effectiveness of international political institutions , as well as diplomacy and negotiation between nations and other security actors. It also depends on, among other factors, effective political inclusion of disaffected groups and the human security of
11186-572: The last 14 million years. Concentrations of methane are far higher than they were over the last 800,000 years. Global human-caused greenhouse gas emissions in 2019 were equivalent to 59 billion tonnes of CO 2 . Of these emissions, 75% was CO 2 , 18% was methane , 4% was nitrous oxide, and 2% was fluorinated gases . CO 2 emissions primarily come from burning fossil fuels to provide energy for transport , manufacturing, heating , and electricity. Additional CO 2 emissions come from deforestation and industrial processes , which include
11305-436: The last two decades. CO 2 is only removed from the atmosphere for the long term when it is stored in the Earth's crust, which is a process that can take millions of years to complete. Around 30% of Earth's land area is largely unusable for humans ( glaciers , deserts , etc.), 26% is forests , 10% is shrubland and 34% is agricultural land . Deforestation is the main land use change contributor to global warming, as
11424-441: The last: internal climate variability processes can make any year 0.2 °C warmer or colder than the average. From 1998 to 2013, negative phases of two such processes, Pacific Decadal Oscillation (PDO) and Atlantic Multidecadal Oscillation (AMO) caused a short slower period of warming called the " global warming hiatus ". After the "hiatus", the opposite occurred, with years like 2023 exhibiting temperatures well above even
11543-608: The loss of Gilgit-Baltistan in the Siege of Skardu to Pakistan in 1947–1948 Indo-Pakistani War . The school was established in December 1948 by General K S Thimayya , then holding the rank of Brigadier . It was initially known as the 19 Infantry Division Ski School . During the winter of 1949–1950, the school was redesignated as a Command Establishment and renamed as the Winter Warfare School . On 8 April 1962, it
11662-608: The lower atmosphere. Carbon dioxide , the primary greenhouse gas driving global warming, has grown by about 50% and is at levels not seen for millions of years. Climate change has an increasingly large impact on the environment . Deserts are expanding , while heat waves and wildfires are becoming more common. Amplified warming in the Arctic has contributed to thawing permafrost , retreat of glaciers and sea ice decline . Higher temperatures are also causing more intense storms , droughts, and other weather extremes . Rapid environmental change in mountains , coral reefs , and
11781-478: The major impacts of ecological changes on national security as: Resources include water, sources of energy, land, and minerals. Availability of adequate natural resources is important for a nation to develop its industry and economic power. For example, in the Persian Gulf War of 1991, Iraq captured Kuwait partly in order to secure access to its oil wells, and one reason for the US counter-invasion
11900-627: The many definitions proposed to date are the following, which show how the concept has evolved to encompass non-military concerns: Potential causes of national insecurity include actions by other states (e.g. military or cyber attack ), violent non-state actors (e.g. terrorist attack ), organised criminal groups such as narcotic cartels , and also the effects of natural disasters (e.g. flooding, earthquakes). Systemic drivers of insecurity, which may be transnational , include climate change , economic inequality and marginalisation , political exclusion , and nuclear proliferation . In view of
12019-413: The more popular term after NASA climate scientist James Hansen used it in his 1988 testimony in the U.S. Senate . Since the 2000s, climate change has increased usage. Various scientists, politicians and media may use the terms climate crisis or climate emergency to talk about climate change, and may use the term global heating instead of global warming . Over the last few million years
12138-672: The population, freedom of speech and information security , social policy and pension provision, housing and communal services, financial services market, protection of property rights, stock markets and circulation of securities, fiscal and customs policy, trade and business, banking services, investment policy, auditing, monetary and exchange rate policy, information security, licensing, industry and agriculture, transport and communications, information technology, energy and energy saving, functioning of natural monopolies, use of subsoil , land and water resources, minerals, protection of ecology and environment and other areas of public administration, in
12257-619: The rate at which heat escapes into space, trapping heat near the Earth's surface and warming it over time. While water vapour (≈50%) and clouds (≈25%) are the biggest contributors to the greenhouse effect, they primarily change as a function of temperature and are therefore mostly considered to be feedbacks that change climate sensitivity . On the other hand, concentrations of gases such as CO 2 (≈20%), tropospheric ozone , CFCs and nitrous oxide are added or removed independently from temperature, and are therefore considered to be external forcings that change global temperatures. Before
12376-522: The rate of Arctic shrinkage and underestimated the rate of precipitation increase. Sea level rise since 1990 was underestimated in older models, but more recent models agree well with observations. The 2017 United States-published National Climate Assessment notes that "climate models may still be underestimating or missing relevant feedback processes". Additionally, climate models may be unable to adequately predict short-term regional climatic shifts. A subset of climate models add societal factors to
12495-622: The rate of yield growth . Fisheries have been negatively affected in multiple regions. While agricultural productivity has been positively affected in some high latitude areas, mid- and low-latitude areas have been negatively affected. According to the World Economic Forum, an increase in drought in certain regions could cause 3.2 million deaths from malnutrition by 2050 and stunting in children. With 2 °C warming, global livestock headcounts could decline by 7–10% by 2050, as less animal feed will be available. If
12614-405: The recent average. This is why the temperature change is defined in terms of a 20-year average, which reduces the noise of hot and cold years and decadal climate patterns, and detects the long-term signal. A wide range of other observations reinforce the evidence of warming. The upper atmosphere is cooling, because greenhouse gases are trapping heat near the Earth's surface, and so less heat
12733-411: The release of chemical compounds that influence clouds, and by changing wind patterns. In tropic and temperate areas the net effect is to produce significant warming, and forest restoration can make local temperatures cooler. At latitudes closer to the poles, there is a cooling effect as forest is replaced by snow-covered (and more reflective) plains. Globally, these increases in surface albedo have been
12852-476: The remaining 23%. Some forests have not been fully cleared, but were already degraded by these impacts. Restoring these forests also recovers their potential as a carbon sink. Local vegetation cover impacts how much of the sunlight gets reflected back into space ( albedo ), and how much heat is lost by evaporation . For instance, the change from a dark forest to grassland makes the surface lighter, causing it to reflect more sunlight. Deforestation can also modify
12971-583: The sea levels by at least 3.3 m (10 ft 10 in) over approximately 2000 years. Recent warming has driven many terrestrial and freshwater species poleward and towards higher altitudes . For instance, the range of hundreds of North American birds has shifted northward at an average rate of 1.5 km/year over the past 55 years. Higher atmospheric CO 2 levels and an extended growing season have resulted in global greening. However, heatwaves and drought have reduced ecosystem productivity in some regions. The future balance of these opposing effects
13090-512: The security of computing devices such as computers and smartphones, as well as computer networks such as private and public networks, and the Internet . It concerns the protection of hardware, software, data, people, and also the procedures by which systems are accessed, and the field has growing importance due to the increasing reliance on computer systems in most societies. Since unauthorized access to critical civil and military infrastructure
13209-537: The security of their regional and international context. For example, Sweden's national security strategy of 2017 declared: "Wider security measures must also now encompass protection against epidemics and infectious diseases, combating terrorism and organised crime, ensuring safe transport and reliable food supplies, protecting against energy supply interruptions, countering devastating climate change, initiatives for peace and global development, and much more." The extent to which this matters, and how it should be done,
13328-451: The sources of strength upon which our future as a nation depends. Some valuables are tangible and earthy; others are spiritual or intellectual. They range widely from political assets such as the Bill of Rights, our political institutions, and international friendships to many economic assets which radiate worldwide from a highly productive domestic economy supported by rich natural resources. It
13447-429: The wide range of risks, the security of a state has several dimensions, including economic security , energy security , physical security , environmental security , food security , border security , and cyber security . These dimensions correlate closely with elements of national power . Increasingly, governments organise their security policies into a national security strategy (NSS); as of 2017, Spain, Sweden,
13566-438: The world. Impacts can be observed on all continents and ocean regions, with low-latitude, less developed areas facing the greatest risk. Continued warming has potentially "severe, pervasive and irreversible impacts" for people and ecosystems. The risks are unevenly distributed, but are generally greater for disadvantaged people in developing and developed countries. The World Health Organization calls climate change one of
13685-655: Was established on 19 November 1998. Although states differ in their approach, various forms of coercive power predominate, particularly military capabilities . The scope of these capabilities has developed. Traditionally, military capabilities were mainly land- or sea-based, and in smaller countries, they still are. Elsewhere, the domains of potential warfare now include the air , space , cyberspace , and psychological operations . Military capabilities designed for these domains may be used for national security, or equally for offensive purposes, for example to conquer and annex territory and resources. In practice, national security
13804-403: Was recognised that military threats to a nation can affect the psyche and social fabric of its people. Therefore, the defence and progress of Singapore are dependent on all of its citizens' resolve, along with the government and armed forces. Total Defence has since evolved to take into consideration threats and challenges outside of the conventional military domain. National security of Ukraine
13923-524: Was sending more energy to Earth, but instead, it has been cooling. This is consistent with greenhouse gases preventing heat from leaving the Earth's atmosphere. Explosive volcanic eruptions can release gases, dust and ash that partially block sunlight and reduce temperatures, or they can send water vapour into the atmosphere, which adds to greenhouse gases and increases temperatures. These impacts on temperature only last for several years, because both water vapour and volcanic material have low persistence in
14042-564: Was the value of the same wells to its own economy. Water resources are subject to disputes between many nations, including India and Pakistan , and in the Middle East . The interrelations between security, energy, natural resources, and their sustainability is increasingly acknowledged in national security strategies and resource security is now included among the UN Sustainable Development Goals . In
14161-689: Was upgraded to a Category A Training Establishment and adopted its current name. HAWS offers two training programmes, the Mountain Warfare course and the Winter Warfare course. The former course is conducted in Sonamarg between May and October each year. The latter course is conducted in Gulmarg between January and April. The two courses train personnel in High Altitude warfare, counter intelligence and survival skills. Ice-craft
