[301] Furthermore, net importers of fossil fuels win economically from switching to clean energy, causing net exporters to face stranded assets: fossil fuels they cannot sell. Almost half of global wetlands have disappeared due to climate change and other human impacts. [336] In 2021, the European Commission released its "Fit for 55" legislation package, which contains guidelines for the car industry; all new cars on the European market must be zero-emission vehicles from 2035. [127] Models are used to estimate the degree of warming future emissions will cause when accounting for the strength of climate feedbacks,[128][129] or reproduce and predict the circulation of the oceans, the annual cycle of the seasons, and the flows of carbon between the land surface and the atmosphere. [169] On the timescale of centuries to millennia, the magnitude of climate change will be determined primarily by anthropogenic CO2 emissions. [24] Since the 2000s, climate change has increased in usage. Today, agriculture takes up 34% of Earth's land area, while 26% is forests, and 30% is uninhabitable (glaciers, deserts, etc.). [214] An expert elicitation concluded that the role of climate change in armed conflict has been small compared to factors such as socio-economic inequality and state capabilities. Ist das comment so okay und das englisch? When the eruption is sufficiently strong (with sulfur dioxide reaching the stratosphere), sunlight can be partially blocked for a couple of years. Klima- und energiepolitischer Rahmen bis 2030 - Climate Action [366][367][368][369] In the 1820s, Joseph Fourier proposed the greenhouse effect to explain why Earth's temperature was higher than the sun's energy alone could explain. [223], Storm intensification. [337] While India has strong incentives for renewables, it also plans a significant expansion of coal in the country. For instance, the change from a dark forest to grassland makes the surface lighter, causing it to reflect more sunlight. Paradebeispiel Klimawandel: Letzter Beitrag: 20 Jan. 09, 14:39: Es geht um einen wissenschaftlichen Titel. [54] Melting of glaciers and ice sheets in the Arctic disrupts ocean circulation, including a weakened Gulf Stream, further changing the climate. [21] Global warming—used as early as 1975[23]—became the more popular term after NASA climate scientist James Hansen used it in his 1988 testimony in the U.S. Climate change Overview Climate change is impacting human lives and health in a variety of ways. Impacts can now be observed on all continents and ocean regions,[189] with low-latitude, less developed areas facing the greatest risk. Drought and high temperatures worsened the 2020 bushfires in Australia. Global Warming comment ich habe ein comment über gloabel warming geschrieben.brauche ich für eine englischarbeit. The Environment: German Vocab & Reading | German Language Blog These include reducing growth in demand for food and other agricultural products, increasing land productivity, protecting and restoring forests, and reducing greenhouse gas emissions from agricultural production. [380], There is a near-complete scientific consensus that the climate is warming and that this is caused by human activities. Klimawandel | Übersetzung Englisch-Deutsch - dict.cc [16], Reducing emissions requires generating electricity from low-carbon sources rather than burning fossil fuels. This corresponds to 10 to 13 years of current emissions. It's here and it's happening now, threatening our food supplies, our infrastructure, our health, and the fabrics of our societies. [106] If solar variations were responsible for the observed warming, the troposphere and stratosphere would both warm. Going forward, battery storage can be expanded, energy demand and supply can be matched, and long-distance transmission can smooth variability of renewable outputs. Species can also be introduced to areas acquiring a favorable climate. [339], As of 2021, based on information from 48 national climate plans, which represent 40% of the parties to the Paris Agreement, estimated total greenhouse gas emissions will be 0.5% lower compared to 2010 levels, below the 45% or 25% reduction goals to limit global warming to 1.5 °C or 2 °C, respectively. [144], Even though the temperature will need to stay at or above 1.5 °C for 20 years to pass the threshold defined by the Paris agreement, a temporary rise above this limit also can have severe consequences. Shown: Telly, Mali (2008). [274] In one of its recent publications, FAO maintains that forest and landscape restoration yields many benefits for the climate, including greenhouse gas emissions sequestration and reduction. Paradebeispiel Klimawandel: Letzter Beitrag: 20 Jan. 09, 14:39: Es geht um einen wissenschaftlichen Titel. [266] A set of actions could reduce agriculture and forestry-based emissions by two thirds from 2010 levels. [135] Additionally, climate models may be unable to adequately predict short-term regional climatic shifts. She concluded that "An atmosphere of that gas would give to our earth a high temperature..."[371][372], Starting in 1859,[373] John Tyndall established that nitrogen and oxygen—together totaling 99% of dry air—are transparent to radiated heat. GLobal Warming - Prüfung, Text aus Englisches Video! - Englisch Forum ... A process known as global warming and that activities pollute the air, water and the earth Ever since the industrial revolution begun, factories, power plants and eventually cars have burned fossil fuels: such as oil and coal. Menschenverursachte Tragödien in der Weltges… 3 Antworten: Klimawandel-Warner: Letzter Beitrag: 06 Mär. Bangladesh after Cyclone Sidr (2007) is an example of catastrophic flooding from increased rainfall. [126] Models also include natural processes like changes in the Earth's orbit, historical changes in the Sun's activity, and volcanic forcing. [340], Public debate about climate change has been strongly affected by climate change denial and misinformation, which originated in the United States and has since spread to other countries, particularly Canada and Australia. Climate is the average weather in a place over many years. By Decision 44 COM 7C, adopted at its extended 44th session (Fuzhou/online, 2021), the World Heritage Committee requested the World Heritage Centre to convene a Panel of experts on Climate Change and World Heritage, with experts drawn from the ad-hoc Working Group, the World Heritage Centre, the Advisory Bodies and other qualified experts in the field of climate science and . [171] These emissions are estimated to have prolonged the current interglacial period by at least 100,000 years. [325], In 2015 all UN countries negotiated the Paris Agreement, which aims to keep global warming well below 2.0 °C and contains an aspirational goal of keeping warming under 1.5 °C. Global Forest Resources Assessment 2015. [286], Adaptation to sea level rise consists of avoiding at-risk areas, learning to live with increased flooding and protection. The IPCC Weighs In", "Forests in the IPCC Special Report on Land Use: 7 Things to Know", "Yale Researcher Anthony Leiserowitz on Studying, Communicating with American Public". [205] Regions dependent on glacier water, regions that are already dry, and small islands have a higher risk of water stress due to climate change. Mild winters allow more pine beetles to survive to kill large swaths of forest. It has caused reduction in global yields of maize, wheat, and soybeans between 1981 and 2010. [4] Additional CO2 emissions come from deforestation and industrial processes, which include the CO2 released by the chemical reactions for making cement, steel, aluminum, and fertiliser. der Themenkomplex Klimawandel: the (complex) set of issues surrounding/around climate change: existenziell; existentiell [alt] {adj} existential: Auch höhere Lebensstandards haben zum Klimawandel geführt, einer existentiellen Bedrohung für unsere Zivilisation. [334] The European Commission presented its European Green Deal with the goal of making the EU carbon-neutral by 2050. [92] Limiting new black carbon deposits in the Arctic could reduce global warming by 0.2 °C by 2050. [202] Crop production will probably be negatively affected in low-latitude countries, while effects at northern latitudes may be positive or negative. 12, 11:37: Klimawandel-Warner und -Skeptiker stehen sich oft unversöhnlich gegenüber. Climate change in a broader sense also includes previous long-term changes to Earth's climate. [246] Heating could be increasingly decarbonised with technologies like heat pumps. Klimawandel - Wörterbuch Deutsch-Englisch - WordReference.com [246][247] For shipping and flying, low-carbon fuels would reduce emissions. [224], Heat wave intensification. [288] In agriculture, adaptation options include a switch to more sustainable diets, diversification, erosion control and genetic improvements for increased tolerance to a changing climate. Klimawandel-Warner und -Skeptiker stehen sich oft unversöhnlich gegenüber. Limiting global warming makes it easier to achieve Sustainable Development Goals, such as eradicating poverty and reducing inequalities. [250] The growth of nuclear power is constrained by controversy around radioactive waste, nuclear weapon proliferation, and accidents. 12, 11:37: Klimawandel-Warner und -Skeptiker stehen sich oft unversöhnlich gegenüber. As part of the European Green Deal, the Commission proposed in September 2020 to raise the 2030 greenhouse gas emission reduction target, including emissions and removals, to at least 55% compared to 1990.. [381][382] No scientific body of national or international standing disagrees with this view. [116] [20], Before the 1980s, when it was unclear whether the warming effect of increased greenhouse gases were 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. [45] Another key indicator is the cooling of the upper atmosphere, which demonstrates that greenhouse gases are trapping heat near the Earth's surface and preventing it from radiating into space. [238] Bioenergy is often not carbon-neutral and may have negative consequences for food security. [109] If cloud cover increases, more sunlight will be reflected back into space, cooling the planet. [273] Farmers can promote sequestration of carbon in soils through practices such as use of winter cover crops, reducing the intensity and frequency of tillage, and using compost and manure as soil amendments. Yet modeling studies indicate the importance of climate effects on disturbance regimes . Environmental Issues - Topics: Klimawandel, Abholzung, Wasser- und Luftverschmutzung, Verschwendung von Nahrungsmitteln. [178], 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. Senate. ", "Myths vs. Facts: Denial of Petitions for Reconsideration of the Endangerment and Cause or Contribute Findings for Greenhouse Gases under Section 202(a) of the Clean Air Act", "Copenhagen failure 'disappointing', 'shameful', "Climate change could impact the poor much more than previously thought", "School climate strikes: 1.4 million people took part, say campaigners", "Oil and gas firms 'have had far worse climate impact than thought', "New renewable energy capacity hit record levels in 2019", "South Korea vows to go carbon neutral by 2050 to fight climate emergency", "Projected Costs of Generating Electricity 2020", "Watery heatwave cooks the Gulf of Maine", "What's in a Name? ", "Time to pay the piper: Fossil fuel companies' reparations for climate damages", UNFCCC, "What is the United Nations Framework Convention on Climate Change? [170] Oceanic CO2 uptake is slow enough that ocean acidification will continue for hundreds to thousands of years. [271], Natural carbon sinks can be enhanced to sequester significantly larger amounts of CO2 beyond naturally occurring levels. [236], Renewable energy is key to limiting climate change. The Northern Hemisphere not only has much more land, but also more seasonal snow cover and sea ice. Afterwards, the ocean's overturning circulation distributes it deep into the ocean's interior, where it accumulates over time as part of the carbon cycle. Themenseite im Fachportal Englisch: Klimawandel und Naturkatastrophen. It impacts how much of the sunlight gets reflected back into space (albedo), and how much heat is lost by evaporation. [20] The main causes of deforestation are: permanent land-use change from forest to agricultural land producing products such as beef and palm oil (27%), logging to produce forestry/forest products (26%), short term shifting cultivation (24%), and wildfires (23%). [197] The World Health Organization (WHO) has estimated that between 2030 and 2050, climate change would cause around 250,000 additional deaths per year. [90] Indirect effects of aerosols are the largest uncertainty in radiative forcing. [179] 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. [307] More direct methods to reduce greenhouse gases include vehicle efficiency standards, renewable fuel standards, and air pollution regulations on heavy industry. The pattern is independent of where greenhouse gases are emitted, because the gases persist long enough to diffuse across the planet. Yet, only the lower atmosphere has warmed, consistent with greenhouse gas forcing. Are we really threatened? [219] These factors can drive environmental migration, both within and between countries. ", "Clean energy: The challenge of achieving a 'just transition' for workers", "Explainer: How 'Shared Socioeconomic Pathways' explore future climate change", "Analysis: Why the IPCC 1.5C report expanded the carbon budget", "Media reaction: Australia's bushfires and climate change", "Climate Change: Atmospheric Carbon Dioxide", "Climate Action: Can We Change the Climate From the Grassroots Up? [14] Under the 2015 Paris Agreement, nations collectively agreed to keep warming "well under 2 °C". Environmental Issues: Definition & Beispiele In 2019, the concentrations of CO2 and methane had increased by about 48% and 160%, respectively, since 1750. Earth's atmosphere is transparent to sunlight, so sunlight reaches the surface where it is converted to heat. [283] More severe climate change requires more transformative adaptation, which can be prohibitively expensive. [333] That same year, the European Parliament declared a "climate and environmental emergency". [100] Restoration/recreation of coastal wetlands, prairie plots and seagrass meadows increases the uptake of carbon into organic matter. Water vapour, as a potent greenhouse gas, holds heat in the atmosphere. The two scientists subsequently helped Charles Keeling to begin a record of continued increase, which has been termed the "Keeling Curve". [331], In 2019, the United Kingdom parliament became the first national government to declare a climate emergency. Z.B. [376], In the 1950s, Gilbert Plass created a detailed computer model that included different atmospheric layers and the infrared spectrum. [348], Climate change came to international public attention in the late 1980s. Land-surface sink processes, such as carbon fixation in the soil and photosynthesis, remove about 29% of annual global CO2 emissions. [238] Fossil fuels accounted for 80% of the world's energy in 2018. [13] Poorer countries are responsible for a small share of global emissions, yet have the least ability to adapt and are most vulnerable to climate change. Global problems such as climate change and terrorism require cooperation based on trust. Gratis Vokabeltrainer, Verbtabellen, Aussprachefunktion. Not only does this increase the absorption of sunlight, it also increases melting and sea-level rise. [21], In the 1980s, the terms global warming and climate change became more common. [354] Partisan gaps also exist in many countries,[355] and countries with high CO2 emissions tend to be less concerned. environment - die Umwelt environmentally-friendly - umweltfreundlich pollution - die Umweltverschmutzung (sometimes shortened to die Verschmutzung) climate change - der Klimawandel global warming - die globale Erwärmung greenhouse effect - der Treibhauseffekt renewable energy - die erneuerbare Energie Climate change Average surface air temperatures 2011-21 compared to 1956-76 Change in average surface air temperature since the Industrial Revolution, plus drivers for that change. Climate change: the basics | Basisfakten über den Klimawandel [61], Greenhouse gases are transparent to sunlight, and thus allow it to pass through the atmosphere to heat the Earth's surface. [39][40], Evidence of warming from air temperature measurements are reinforced with a wide range of other observations. Of these emissions, 75% was CO2, 18% was methane, 4% was nitrous oxide, and 2% was fluorinated gases. More highly educated people, and in some countries, women and younger people, were more likely to see climate change as a serious threat. Per-capita emissions were also still relatively low in developing countries and developing countries would need to emit more to meet their development needs. However, water vapour and gases such as methane and carbon dioxide absorb radiated heat and re-radiate that heat into the atmosphere. Habe es mit einem Freund geschrieben.. [384] The 2021 IPCC Assessment Report stated that it is "unequivocal" that climate change is caused by humans. [115], Another major feedback is the reduction of snow cover and sea ice in the Arctic, which reduces the reflectivity of the Earth's surface. [154] Over the 21st century, the IPCC projects that in a very high emissions scenario the sea level could rise by 61–110 cm. [255] Meeting the Paris Agreement goals that limit warming to a 2 °C increase could save about a million of those lives per year by 2050, whereas limiting global warming to 1.5 °C could save millions and simultaneously increase energy security and reduce poverty. [300], The geopolitics of climate change is complex. Although its current use is limited in scale and expensive,[278] carbon capture and storage (CCS) may be able to play a significant role in limiting CO2 emissions by mid-century. der Klimawandel - LEO: Übersetzung im Englisch ⇔ Deutsch Wörterbuch [345] An echo chamber of climate-denying blogs and media has further fomented misunderstanding of climate change. IEA – Projected Costs of Generating Electricity 2020, "Nuclear power in the 21st century: Challenges and possibilities", "Low and zero emissions in the steel and cement industries", National Academies of Sciences, Engineering, and Medicine 2019, "Soil organic carbon changes and distribution in cultivated and restored grassland soils in Saskatchewan", Climate Change 2022: Impacts, Adaptation and Vulnerability. Klimawandel in English - Cambridge Dictionary However, heatwaves and drought have reduced ecosystem productivity in some regions. [105] Further evidence for greenhouse gases causing global warming comes from measurements that show a warming of the lower atmosphere (the troposphere), coupled with a cooling of the upper atmosphere (the stratosphere). But at the same time, this kind of urban development may increase the urban heat island effect, leading to higher temperatures and increased exposure of people to heat-related health risks. World Heritage Centre - Climate Change and World Heritage Klimawandel : Dictionary / Wörterbuch (BEOLINGUS, TU Chemnitz) Scenarios that limit global warming to 1.5 °C typically project the large-scale use of carbon dioxide removal methods over the 21st century. Englisch / Beispiel comment "global warming" . ", "How Effective Is Land At Removing Carbon Pollution? [143] However, it is clear that fossil fuel resources are too abundant for shortages to be relied on to limit carbon emissions in the 21st century. Secondly, more compact urban development may lead to reduced emissions from transport and construction which is good. Vernetze dich mit . Paradebeispiel Klimawandel: Letzter Beitrag: 20 Jan. 09, 14:39: Es geht um einen wissenschaftlichen Titel. Around the same time, Hans Suess found evidence that CO2 levels had been rising, and Roger Revelle showed that the oceans would not absorb the increase. [326] The agreement replaced the Kyoto Protocol. [323] The Accord set the goal of sending $100 billion per year to developing countries for mitigation and adaptation by 2020, and proposed the founding of the Green Climate Fund. From 1961 to 1990, a gradual reduction in the amount of sunlight reaching the Earth's surface was observed. Over 100,000 English translations of German words and phrases. It has often been framed as a free-rider problem, in which all countries benefit from mitigation done by other countries, but individual countries would lose from switching to a low-carbon economy themselves.
