98-438: 8°54′N 11°22′E / 8.900°N 11.367°E / 8.900; 11.367 Jalingo is the capital city of Taraba State in north-eastern Nigeria , named in fulfulde (the word Jalingo means "superior place") and has been estimated with population of 418,000 as of 2018, The city has received the highest number of immigrants mainly from, Kano , Borno , Gombe and the neighboring Cameroon . As of November, 2022
196-677: A classical European understanding of the known world : Europe , North Africa , and Southwest Asia . The phrase is related to the enduring power of the city first as the capital of the Republic and the Empire , and later as the centre of the Catholic Church . In several English-speaking states , the terms county town and county seat are also used in lower administrative divisions . In some unitary states , subnational capitals may be known as 'administrative centres'. The capital
294-497: A monarch held his or her court, the selection, relocation, founding, or capture of a modern capital city is a highly symbolic event. For example: The capital city is usually but not always a primary target in a war, as capturing it usually guarantees capture of much of the enemy government, victory for the attacking forces, or at the very least demoralization for the defeated forces. In ancient China , where governments were massive centralized bureaucracies with little flexibility on
392-562: 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
490-445: A compromise between two or more cities or other political divisions, historical reasons, or enough land was needed to deliberately build a new planned city for the capital. The majority of national capitals are also the largest city in their respective countries. Modern examples are Beijing , Berlin , Cairo , London , Madrid , Mexico City , Moscow , Paris , Rome , Jakarta , Metro Manila , Seoul , and Tokyo . Counties in
588-590: 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
686-405: A distinction is made between the official ( constitutional ) capital and the seat of government, which is in another place . English-language news media often use the name of the capital city as an alternative name for the government of the country of which it is the capital, as a form of metonymy . For example, the "relations between London and Washington " refers to the " relations between
784-542: 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
882-412: 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
980-470: A matter of convention, and because all or almost all the country's central political institutions, such as government departments, supreme court, legislature, embassies, etc., are located in or near them. Many modern capital cities are located near the centre of the country, so that they are more accessible to its population and have better protection from possible invasions. (See also § Capitals in military strategy ) The location may also be based on
1078-408: 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

1274-461: 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
1372-474: 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
1470-417: A small share of global emissions , yet have the least ability to adapt and are most vulnerable to climate change . 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
1568-554: A territory: Plymouth in Montserrat . There are several countries where, for various reasons, the official capital and seat of government are separated: Some historical examples of similar arrangements, where the recognized capital was not the official seat of government: With the rise of the modern nation-state , the capital city has become a symbol for the state and its government , and imbued with political meaning. Unlike medieval capitals, which were declared wherever
1666-428: A usual increase in rainfall on the crest and to the windward and a rain shadow on the leeward side, Jalingo's climate exhibits a straightforward pattern of east-west climatic zones that has been modified by the influence of some highlands. With an average daily high temperature of 96 °F, the hot season lasts for 2.3 months, from February 4 to April 15. With an average high of 99 °F and low of 74 °F, March
1764-548: 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
1862-519: 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,
1960-564: 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
2058-711: 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
SECTION 20
#17327825417632156-399: 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
2254-500: Is often the largest city of its constituent, though not always . Historically, the major economic centre of a state or region has often become the focal point of political power, and became a capital through conquest or federation . Historical examples are ancient Babylon , ancient Athens , ancient Rome , Abbasid Baghdad , Constantinople , Chang'an , and ancient Cusco . The modern capital city has not always existed: in medieval Western Europe, an itinerant (wandering) government
2352-450: 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
2450-444: 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
2548-516: 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
2646-482: Is the hottest month of the year in Jalingo. With an average daily high temperature below 86 °F, the cool season lasts for 3.4 months, from June 25 to October 6. In Jalingo, December is the coldest month of the year, with an average low of 63 °F and high of 91 °F. The average proportion of sky covered by clouds in Jalingo varies significantly seasonally throughout the year. Around October 30 marks
2744-524: Is the municipality holding primary status in a country , state , province , department , or other subnational division , usually as its seat of the government . A capital is typically a city that physically encompasses the government's offices and meeting places; the status as capital is often designated by its law or constitution . In some jurisdictions , including several countries, different branches of government are in different settlements, sometimes meaning multiple official capitals. In some cases,
2842-582: Is the case with Nanjing by Shanghai , Quebec City by Montreal , and several US state capitals . The decline of a dynasty or culture could also mean the extinction of its capital city, as occurred at Babylon and Cahokia . "Political nomadism" was practiced in ancient Near East to increase ties between the ruler and the subjects. Although many capitals are defined by constitution or legislation, many long-time capitals have no such legal designation, including Bern , Edinburgh , Lisbon , London , Paris , and Wellington . They are recognized as capitals as
2940-407: 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
3038-417: 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

Similarly, each of the autonomous communities of Spain and regions of Italy has a capital city, such as Seville and Naples , while Madrid is the capital of the Community of Madrid and of
3234-511: The Atlantic meridional overturning circulation (AMOC), and irreversible damage to key ecosystems like the Amazon rainforest and coral reefs can unfold in a matter of decades. The long-term effects of climate change on oceans include further ice melt, ocean warming , sea level rise, ocean acidification and ocean deoxygenation. The timescale of long-term impacts are centuries to millennia due to CO 2 's long atmospheric lifetime. The result
3332-523: The Byzantine capital, Constantinople , Byzantine forces were able to regroup in several provinces; provincial noblemen managed to reconquer the capital after 60 years and preserve the empire for another 200 years after that. The British forces sacked various American capitals repeatedly during the Revolutionary War and War of 1812 , but American forces could still carry on fighting from
3430-661: 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
3528-573: 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
3626-840: 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
3724-635: 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
3822-695: The Kingdom of Spain as a whole and Rome is the capital of Italy and of the region of Lazio . In the Federal Republic of Germany , each of its constituent states (or Länder , plural of Land ) has its own capital city, such as Dresden , Wiesbaden , Mainz , Düsseldorf , Stuttgart , and Munich , as do all of the republics of the Russian Federation . The national capitals of Germany and Russia (the Stadtstaat of Berlin and

Aminu Jauro as the caretaker Chairman of Jalingo. Jalingo as the capital city of Taraba State has many markets, but the major recognized markets are: The wet season in Jalingo is oppressive and cloudy , the dry season is partly cloudy, and it's hot all year round. The average annual temperature ranges from 61 to 99 degrees Fahrenheit , with lows and highs of 56 and 105 degrees respectively. With

4116-518: The World Economic Forum , 14.5 million more deaths are expected due to climate change by 2050. 30% of the global population currently live in areas where extreme heat and humidity are already associated with excess deaths. 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
4214-414: 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
4312-402: The climate system . Solar irradiance has been measured directly by satellites , and indirect measurements are available from the early 1600s onwards. Since 1880, there has been no upward trend in the amount of the Sun's energy reaching the Earth, in contrast to the warming of the lower atmosphere (the troposphere ). The upper atmosphere (the stratosphere ) would also be warming if the Sun

A few nation-states have multiple capitals, and there are also several states that have no capital. Some have a city as the capital but with most government agencies elsewhere. There is also a ghost town which is currently the de jure capital of
4508-971: 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

Vienna , the national capital of Austria , is also one of the states, while Bern is the ( de facto ) capital of both Switzerland and of the Canton of Bern . Governing entities sometimes plan, design and build new capital cities to house
4704-432: The socioeconomic scenario and the mitigation scenario, models produce atmospheric CO 2 concentrations that range widely between 380 and 1400 ppm. The environmental effects of climate change are broad and far-reaching, affecting oceans , ice, and weather. Changes may occur gradually or rapidly. Evidence for these effects comes from studying climate change in the past, from modelling, and from modern observations. Since
4802-405: 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
4900-612: The 1950s, droughts and heat waves have appeared simultaneously with increasing frequency. Extremely wet or dry events within the monsoon period have increased in India and East Asia. Monsoonal precipitation over the Northern Hemisphere has increased since 1980. The rainfall rate and intensity of hurricanes and typhoons is likely increasing , and the geographic range likely expanding poleward in response to climate warming. Frequency of tropical cyclones has not increased as
4998-500: 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

#17327825417635096-440: The Arctic is forcing many species to relocate or become extinct . Even if efforts to minimize future warming are successful, some effects will continue for centuries. 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
5194-435: 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,
5292-545: 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
5390-604: 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,

They are the one that run the affairs of the state. The elected Chairman of Jalingo during the last election in 2020 was Hon. Abdulnaseer Bobboji of People Democratic Party (PDP). He had been the Caretaker Chairman until when his tenure ended up on Sunday, 3 July 2022. Following that,

The word capital derives from the Latin word caput (genitive capitis ), meaning ' head ', later borrowed from Medieval Latin capitālis ('of the head'). The Latin phrase Roma Caput Mundi meaning 'Rome capital of the world' ( lit. ' head of the world ' ) was already used by the poet Ovid in 1st century BC . It originates out of

The effect of decreasing sulfur content of fuel oil for ships since 2020 is estimated to cause an additional 0.05 °C increase in global mean temperature by 2050. As the Sun is the Earth's primary energy source, changes in incoming sunlight directly affect
5782-411: The atmosphere , for instance by increasing forest cover and farming with methods that capture carbon in soil . Before the 1980s it was unclear whether the warming effect of increased greenhouse gases was stronger than the cooling effect of airborne particulates in air pollution . Scientists used the term inadvertent climate modification to refer to human impacts on the climate at this time. In
5880-452: The atmosphere. volcanic CO 2 emissions are more persistent, but they are equivalent to less than 1% of current human-caused CO 2 emissions. Volcanic activity still represents the single largest natural impact (forcing) on temperature in the industrial era. Yet, like the other natural forcings, it has had negligible impacts on global temperature trends since the Industrial Revolution. The climate system's response to an initial forcing

#17327825417636076-720: The capital has been changed for geopolitical reasons; Finland 's first city, Turku , which had served as the country's capital since the Middle Ages under the Swedish rule, lost its position during the Grand Duchy of Finland in 1812, when Helsinki was made the current capital of Finland by the Russian Empire. The convergence of political and economic or cultural power is by no means universal. Traditional capitals may be economically eclipsed by provincial rivals as
6174-540: The carbon cycle, such as the fertilizing effect of CO 2 on plant growth. Feedbacks are expected to trend in a positive direction as greenhouse gas emissions continue, raising climate sensitivity. These feedback processes alter the pace of global warming. For instance, warmer air can hold more moisture in the form of water vapour , which is itself a potent greenhouse gas. Warmer air can also make clouds higher and thinner, and therefore more insulating, increasing climate warming. The reduction of snow cover and sea ice in

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
6468-617: The countryside, where they enjoyed support from local governments and the traditionally independent civilian frontiersmen. Exceptions to these generalizations include highly centralized states such as France , whose centralized bureaucracies could effectively coordinate far-flung resources, giving the state a powerful advantage over less coherent rivals, but risking utter ruin if the capital were taken. Climate change Present-day climate change includes both global warming —the ongoing increase in global average temperature —and its wider effects on Earth's climate . Climate change in
6566-684: 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

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
6762-427: 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
6860-401: 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
6958-444: 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
7056-610: 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
7154-484: The eighteenth century. In Canada , there is a federal capital , while the ten provinces and three territories each have capital cities. The states of such countries as Mexico , Brazil (including the famous cities of Rio de Janeiro and São Paulo , capitals of their respective states), and Australia also each have capital cities. For example, the six state capitals of Australia are Adelaide , Brisbane , Hobart , Melbourne , Perth , and Sydney . In Australia,
7252-430: 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
7350-604: 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
7448-545: The great crisis of Japanese invasion . National capitals were arguably less important as military objectives in other parts of the world, including the West, because of socioeconomic trends toward localized authority, a strategic modus operandi especially popular after the development of feudalism and reaffirmed by the development of democratic and capitalistic philosophies. In 1204, after the Latin Crusaders captured
7546-572: 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
7644-436: 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
7742-441: 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
7840-608: 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
7938-413: 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
8036-466: The provincial level, a dynasty could easily be toppled with the fall of its capital. In the Three Kingdoms period, both Shu and Wu fell when their respective capitals of Chengdu and Jianye fell. The Ming dynasty relocated its capital from Nanjing to Beijing , where they could more effectively control the generals and troops guarding the borders from Mongols and Manchus . The Ming
8134-619: 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
8232-522: 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
8330-622: 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
8428-405: 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
8526-411: 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
8624-476: 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
8722-583: 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
8820-424: The seat of government of a polity or of a subdivision. Deliberately planned and designed capitals include: These cities satisfy one or both of the following criteria: Some examples of the second situation (compromise locations) are: Changes in a nation's political regime sometimes result in the designation of a new capital. Akmola (renamed Astana in 1998) became the capital of Kazakhstan in 1997, following
8918-552: The sky being overcast or mostly cloudy 82% of the time on average. Africa, particularly Nigeria, is highly vulnerable to the effects of climate change due to its geographical characteristics, including its arid northern border and coastal southern region. The region's heavy reliance on rain-fed agriculture, coupled with prevalent poverty and limited response capabilities, magnify its susceptibility. This situation, combined with insufficient adaptation measures and financial constraints among individuals, results in significant threats to both
9016-555: The social and economic well-being of Africa's population. Adverse consequences stemming from climate change, such as heightened temperatures, diminished water resources, loss of biodiversity, and increased disease transmission, significantly impact livelihoods. The lack of awareness, especially among less educated communities, contributes to behaviors that exacerbate the issue. Mobilizing the sizable student population in Nigerian tertiary institutions for climate change awareness can serve as
9114-404: The start of Jalingo's clearer season, which lasts for 4.2 months and ends around March 6. In Jalingo, January is the clearest month of the year, with the sky remaining clear, mostly clear, or partly cloudy 51% of the time on average. Beginning about March 6 and lasting for 7.8 months, the cloudier season of the year ends around October 30. May is the cloudiest month of the year in Jalingo, with
9212-677: The term "capital cities" is regularly used to refer to those six state capitals plus the federal capital Canberra , and Darwin , the capital of the Northern Territory . Abu Dhabi is the capital city of the Emirate of Abu Dhabi and also of the United Arab Emirates overall. In unitary states which consist of multiple constituent nations, such as the United Kingdom and the Kingdom of Denmark , each will usually have its own capital city. Unlike in federations , there
9310-438: 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
9408-820: Was common. The capital city attracts politically motivated people and those whose skills are needed for efficient administration of national or imperial governments, such as lawyers , political scientists , bankers , journalists , and public policy makers . Some of these cities are or were also religious centres , e.g. Constantinople (more than one religion), Rome / Vatican City (the Roman Catholic Church ), Jerusalem (more than one religion), Babylon, Moscow (the Russian Orthodox Church ), Belgrade (the Serbian Orthodox Church ), Paris, and Beijing. In some countries,
9506-632: Was destroyed when Li Zicheng took their seat of power, and this pattern repeats itself in Chinese history, until the fall of the traditional Confucian monarchy in the 20th century. After the Qing dynasty 's collapse, decentralization of authority and improved transportation and communication technologies allowed both the Chinese Nationalists and Chinese Communists to rapidly relocate capitals and keep their leadership structures intact during
9604-524: 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
