Climate change has caused temperatures in the world to rise in the last few decades, and temperatures in Europe have risen twice as fast as the average change in the rest of the world. [1] In Spain, which already has a hot and dry climate, extreme events such as heatwaves are becoming increasingly frequent. [2] [3] The country is also experiencing more episodes of drought and increased severity of these episodes. [4] Water resources will be severely affected in various climate change scenarios. [5]
To mitigate the effects of climate change, Spain is promoting an energy transition to renewable energies, such as solar and wind energy. [6] In 2021, to support this process, the government approved a law on climate change and energy transition. [7]
Spanish society as a whole is one of the most climate change conscious societies in the EU. [8] Due to the effects of global warming, Spanish society is demanding stronger measures. [9]
Four sectors generate 90% of emissions: transport, industry, agriculture and energy. [10]
Per capita CO2 emissions (not including land use change) were 5 tonnes in 2021. [11] Spain accounts for 9% of the total CO2 emissions in the European Union. [12] CO2 emissions are dominated by the combustion of fossil fuels for transport and electricity generation, and by the industrial production of materials such as cement. [13]
A large part of Spain's energy demand comes from fossil fuels, which account for over 70% of the total. In 2021 oil was responsible for 60% of the emissions and natural gas 30% of emissions. [14] [ page needed ] [15]
Greenhouse gas emissions are the highest in the transportation sector, accounting for 27% of total GHG emissions. [16] Of that, 90% of emissions come from road transport, with light-duty vehicles, such as passenger cars and motorbikes, contributing 66% and heavy trucks and buses accounting for the remaining 34%. [17]
Spain is considered an energy island, as its electricity import and export capacity is very limited, at 2.8 GW with France and 3.70 GW with Portugal. [18]
In 2022 coal-fired power plants emitted 15% of the CO2 from electricity generation, [18] but these will be shut down by 2030. [15] Almost all the rest is from gas-fired power plants. [18]
In the Balearic Islands electricity production is mainly natural gas and some solar energy, while the Canary Islands produce almost all their electricity with oil. [18]
Agriculture produces two potent greenhouse gasses: nitrous oxide and methane. [13]
Between 1965 and 2015 the average temperature rose by 1.5 °C (2.7 °F). [2] According to Aemet the frequency of heatwaves have doubled since 2010. Between 1980 and 2000 were 10 to 12 heatwaves per decade, whereas between 2010 and 2020 there were 24. The duration of these heatwaves will also be longer, with at least 41 days of extreme heat predicted in 2050 and, in the worst emissions scenario, 50 days. Compare this to heatwaves in 1971-2000 when the average number of days was 21 days annually. [3]
Based on the IPCC reports, different scenarios have been developed in order to study the future climate. The AEMET (Spanish meteorology agency) has studied how three of these would affect the Spanish climate through the year 2100: RCP 4.5, RCP 6, and RCP 8.5. The first scenario (RCP 4.5) envisages an increase in greenhouse gas emissions for several more decades, before stabilising and then decreasing before the end of the century. The RCP 8.5 scenario models the most extreme case, with no regulation of greenhouse gas emissions. [22]
In the best-case scenario (RCP 4.5), between 2081 and 2100 the annual maximum temperature would increase 2–4 °C (3.6–7.2 °F), with an uncertainty of 0.5–1.5 °C (0.90–2.70 °F). [22] In RCP 6.0 that becomes an increase of 1-4 °C ± 0.5-1.5 °C (1.8–7.2 °F ± 0.90–2.70 °F) between 2046 and 2065, and of 3–5 °C (5.4–9.0 °F) between 2081 and 2100. [22]
In the worst-case scenario (RCP 8.5), the annual maximum temperature increases of 4–7 °C (7.2–12.6 °F) are expected for 2081–2100. In this scenario there is an uncertainty of 1.5–3 °C (2.7–5.4 °F). [22]
Changes are also predicted regarding precipitation. In scenario RCP 4.5, predicted changes for the years 2081-2100 range from +10% (in specific localised regions) to -20% with an uncertainty of up to 30%. Whereas in scenario RCP 8.5 the expected annual precipitation change varies from +10% to -30% with uncertainties of 10-30% between 2081 and 2100. [22]
Of Spain's many heat waves, some that stand out are: [23]
Climate change made the April 2023 heatwave at least 100 times more likely. [24] The previous year (2022) heatwaves killed almost 4,000 people in Spain. [25]
The winter of 2022-2023 was, in general, hot and humid. December 2022 was the hottest December in the historical record, with the winter being the fifth hottest of the 21st century. [26]
In March 2022 AEMET analysed the previous 12 months and found that peninsular Spain has been in a meteorological drought since January 2022. These events are probably made more likely by climate change. [26]
The annual precipitation was 601.2 mm (23.7 in) between 1991 and 2020, and may decrease by 64.52 mm (2.5 in) in 2040–2059. [2] The effect that climate change has on water resources can be worse in regions that already have low water resources levels and recurring droughts. [5]
According to existing climate change scenarios, Spain's water resources will be severely affected. However, these effects are difficult to accurately measure due to the natural variability of the water cycle and the impact of water usage on flow rates. As a result, enhancing the assessment of climate change impacts by hydrological simulation models is needed. [5]
River basin districts with a higher water exploitation index appear to experience more significant reductions in mean annual runoff. If the predicted climate change scenarios in Spain materialize, the traditional measures used to combat water scarcity must be applied more intensely and in ways consistent with regional effects on water resources. Policymakers in Spain face the challenge of understanding the impact of climate change and devising and executing policies that guarantee the best adaptation to the expected decrease in water resources in the most impacted regions, particularly those already facing water scarcity. [5]
Water resources in Spain are expected to experience temperature increases, more frequent and severe droughts and floods, and decreases in river flows, resulting in reduced water availability. These impacts may aggravate existing conflicts between Spanish regions and further elevate water as a potential powerful political tool. [27]
The Ebro Delta is a significant wetland area in the western Mediterranean, about 40% of the delta plain is less than 0.5 metres (20 in) above mean sea level, and parts of the southern margin are at mean sea level but protected by dikes. The delta may see a sea level rise of at least 3 mm (1⁄8 in) per year. [28] The government is investing millions of euros into shifting sediments to alleviate the impacts of erosion, however this is not seen as a long-term solution. [29]
To offset negative impacts from waterlogging and saltwater intrusion, and to maintain land elevation, future management plans should consider the relative sea level rise. Plans will also need to regulate freshwater and sediment flows from the river. Doing this will entail the partial removal of sediments trapped behind the Ribarroja Dam and Mequinença Dam, as the stocks and inputs of sediments in the corresponding reservoirs are sufficient to elevate the delta plain by around 50 cm (20 in). [28]
Coastal measurements indicate that the global mean sea level has risen at a rate of 1.8 mm (1⁄16 in) per year from 1950 to 2000, with regional variability. Gauge records in the Bay of Biscay indicate that sea-level rise is accelerating, which is in line with rates observed from satellite imagery in the open ocean since 1993. [30]
Coastal habitats have been mapped via historical airborne photography since 1954 and via high-resolution imagery since 2004. The analysis of tide gauge records from Santander in northern Spain shows that relative mean sea level has been rising at a rate of 2.08 ± 0.33 mm (0.082 ± 0.013 in) per year from 1943 to 2004, consistent with trends from measurements elsewhere in the region. Using a LIDAR-based DTM, the study predicts an 11.1 ha (27 acres) sea-level rise in the Gipuzkoan coast within a 50-year period. However, only 2.95 hectares (7.3 acres) change was detected from historical and recent orthophotography, possibly due to sea-level rise. While 98 hectares (240 acres; 0.98 km2; 0.38 sq mi) were transformed by human impacts, suggesting that human impact poses a greater threat to Basque coastal and estuarine habitats than natural erosive processes and global climate change. [30]
A study conducted in northeast Spain concluded that the disappearances of white-clawed crayfish, Mediterranean barbel, chub, European eel, and southern water vole were clearly related to the hydrological changes of the studied stream. The study suggested that no other factors could explain their disappearance: there is no industrial or agrarian sewage in the Olzinelles valley that could cause water quality to deteriorate; the industrial pollution in the river Tordera has been reduced by the construction of sewage treatment plants and other administrative measures; these species had no market value in the study area, and fishing and capturing were occasional, making it unlikely that negative effects on their populations resulted from these activities. Additionally, the human pressure on these species has decreased over the years, as the valley's population dropped by 76% from 1924 to 2007. [31]
The disappearance of white-clawed crayfish in the Olzinelles stream may have been due to the loss of water flow or from the impact of red swamp crayfish. The red swamp crayfish became one of the most widespread invasive species in Spain after its introduction to streams in the Montnegre Mountains in 1989. Though as of 2011 surveys conducted in the Olzinelles stream had not found the crayfish, which was believed related to the absence of water. [31]
Although the scientific community has made significant progress in predicting the magnitude and regional variation of climate change in upcoming decades, it is remains challenging to estimate the economic costs of climate change. The challenge mainly lies in the uncertainties of future climate change and economic projections, as well as the intricacies of connecting physical impacts and economic processes. [32]
As many of the tourist activities in Spain are weather-dependent, the industry may be strongly impacted by climate change. It has been projected that the Tourist Climate Index (TCI), which was 'excellent' and 'very good' during the summers (June–August) of 1961 through 1990, will become 'acceptable' around Spain, and 'good' and 'very good' in the north of the country for the years 2051–2080. [32]
Climate change impacts are being observed globally, with certain regions that are already water scarce having higher levels of vulnerability. Spain is predicted to be highly vulnerable because of uneven availability of water resources, and due to existing demands. As a result of its geographic and socio-economic characteristics, Spain is regarded as one of the most vulnerable countries to climate change in the European Union. Models forecast further increases in temperature and reductions in precipitation, which will likely have a profound impact on the region. [33]
Desertification, one of the most significant impacts of climate change in Spain, poses a significant threat to a substantial portion of the country. Over 30% of the area is already severely impacted by desertification, with human activity in arid regions exacerbating the situation. Causes of desertification include forest fires, loss of vegetation cover, erosion, and salinization processes. Climate change projections predict an exacerbation of these issues, particularly in regions with a dry and semi-arid Mediterranean climate. [33]
The agricultural sector is responsible for about 10% of greenhouse gas emissions in Spain. Livestock, particularly pig manure management, accounts for over half the emissions, while crop systems account for the remainder. While agriculture has shown the ability to adapt to long term changes, the magnitude of the changes due to climate change is likely to exceed the adaptive capacity of many European farmers. Therefore, sustainable agriculture requires the synergy of adaptation and mitigation, with no clear separation between them. The Spanish agriculture sector has already implemented several measures aimed at reducing emissions, improving knowledge about them, and introducing energy efficiency criteria in modernizing irrigation systems. [33]
Climate change will have significant impacts on agriculture, ecosystems, and biodiversity, resulting in alterations to Spain's characteristics, accentuating the existing desertification issues, reducing water availability, increasing costs of adaptation measures, and potentially causing future problems such as pests, invasive species, and reduced crop yields. While agriculture is responsible for significant emissions, the efforts being made to address this also recognize its role as a carbon sink. [33]
Between 1998 and 2012 over three thousand people died annually due to heatwaves. In the worst-case scenario that number could become 14,500 in 2035-2064 and over 30,000 between 2070 and 2099. [3]
Rising temperatures, ozone levels, and fine dust concentrations, particularly in urban areas, have been found to increase heat stress, leading to higher risk of death from various health conditions including ischaemic heart disease, stroke, metabolic disorders, and kidney disease. The health impacts of climate change may disproportionately affect groups such as people with chronic illnesses, the elderly, children, and people who are pregnant. [34]
The Institute for the Diversification and Saving of Energy (IDAE) is a public entity that has, since its origin, been in charge of the promotion of renewable energies. The IDAE was in charge of carrying out the National Renewable Energy Action Plan 2011–2020, which achieved the 2020 renewable energy objectives, thereby complying with the EU directive to have 20% of energy consumption come from renewable sources. The organization is also charged with meeting the new target of 27% renewable energy by 2030, the commitment the EU made at the Paris climate change conference in 2016 in order to limit the global temperature increase to 1.5 °C (2.7 °F). This support and promotion of renewable energies by Spain and the EU has reduced their costs, especially solar and wind power, turning them into competitive technologies as in some cases they are cheaper than fossil fuels. [6]
The contribution of renewable energies to the electricity generation mix approaches 40%, [6] as Spain has about 3000 hours of sunlight per year, making it one of the sunniest countries in Europe and one with large solar resources. [35] Solar energy generation had a record year in Spain in 2022, growing by 33% and becoming the fourth largest source of electricity. With a generation of 28,000 GWh, and an increase in installed capacity of 3.4 GW, solar energy has seen the greatest growth in production capacity. [36]
Another sector with strong growth is solar energy for self-consumption, which, with an installed capacity of 2,507 MW compared to 1,203 MW in 2021, saw growth of 108%. Spain has an installed self-consumption capacity totaling 5,249 MW. This boom has largely been possible due to a progressive elimination of barriers and local incentives. [37]
In Europe, Spain comes second in terms of wind energy generation and the fourth in terms of installed capacity with a capacity of 30.8 GW. The world's leading renewable energy producer, one of the five largest electricity companies in the world, is Spanish and the leading solar thermal companies are also Spanish. Spain has the largest installed capacity of solar thermal power in the world, with commercial operation in all four currently available technologies: tower, enclosed-parabolic trough, fresnel and dishes. [6]
Control Centre of Renewable Energies (CECRE) is the world's leading renewable energy control centre, which is responsible for ensuring the integration of large shares of renewables into the electricity sector and markets, which presents challenges due to intermittency. Another problem is that Spain is an energy island, as its small electricity interconnection with France does not allow the exchange of energy with the rest of the European continent. The CECRE is the first national control centre in the world dedicated exclusively to monitoring and controlling renewable energy production, maximising its integration, and guaranteeing the security of the electricity system. [6]
There is also the special case of El Hierro, which uses 100% renewable energy. It is a self-sufficient and sustainable island with a hybrid system of wind and hydro energy that covers the entire energy demand of the island. El Hierro stores the surplus wind energy by means of hydroelectric power. [6]
The transportation sector has the highest energy consumption in Spain, accounting for 40.4% of the total demand. Of that demand road transport accounts for 81.3%, the vast majority of which uses imported oil. This energy dependence cost approximately €40 billion in 2014, equivalent to 3.8% of Spain's GDP, with consequent problems for the economy, environment, and energy security. [38]
In order to solve this problem, policies have been established at the national level, with a special focus on trucks, private cars, and buses, which account for the largest share of road transport consumption. Spain approved the Strategy for Boosting Alternative Energy in 2015 and the National Action Framework for the development of the market and the infrastructures for alternative fuels in the transport sector in 2016. These measures are structured according to 3 priorities: infrastructure, market and industrialisation. [38]
Spain has several factories that produce alternative fuels for vehicles, as well as companies that produce the infrastructure equipment for recharging. Electric vehicles on Spanish roads account for less than 1% of all vehicles, although the number of electric vehicles has been increasing. For the promotion of these electric vehicles, and more sustainable transport in general, the Spanish government has launched the MOVES III Plan. The plan, provides direct aid to electric vehicles and charging infrastructure, has a €400 million budget, with the option to increase it to €800 million depending on demand. [39]
The beneficiaries of the MOVES III Plan can be individuals or companies, as long as they purchase an electric vehicle, a plug-in hybrid, or an electric vehicle with a long range. The price of the vehicle must be less than €45,000, and the maximum aid is €7,000. [39]
Spain is the European leader in sustainable rail transportation, as its 3,100 km (1,900 mi) of high speed train tracks are the most extensive high speed network in Europe. Reaching speeds of 310 km/h (190 mph), it possible to connect the North and South of the country in 5 hours. [40] Also 90% of the vehicles using compressed natural gas are public buses, and use in taxis is increasing in some metropolitan areas. [38]
On September 11, 2019, Spain declared a climate emergency. [41]
In 2021, the Spanish parliament approved a law on climate change and energy transition that calls for a 23% reduction of emissions by 2030 (compared to 1990 levels) and carbon neutrality by 2050. By or before 2030 all coal-fired power plants will have been shut down and coal-phase out is supported by EU funds for a just transition. [15] By 2040 Spain plans to limit car sales to electric vehicles. [42]
On 20 May 2021, The Climate Change and Energy Transition Law went into force; the law requires reaching climate neutrality by 2050 at the latest. Article 3 establishes the long-term objective of decarbonising the economy by 2050 with a 100% renewable electricity system. In addition, the law establishes a series of shorter term objectives, including: reducing greenhouse gas emissions at least 23% by 2030, compared to 1990 levels; achieving 42% renewable energy in energy consumption and 74% renewable energy in electricity generation; as well as reducing energy consumption by 39.5% by improving energy efficiency. [7]
The law also prohibits authorisations for hydrocarbon exploration and exploitation, instead establishing direct subsidies for biogas, biomethane, hydrogen and other renewable fuels. By 2040 new commercial vehicles must all be zero emission and by 2023[ needs update ] all municipalities with more than 50,000 inhabitants, and all islands, must implement their own climate change mitigation measures. [7]
Law 7/2021 on climate change and energy transition establishes 7 main objectives: [43]
Spain signed the Paris Agreement on 22 April 2016 and ratified it on 12 June 2017. Prior to this agreement, Spain had signed the Kyoto Protocol on 29 April 1998, which was ratified on 31 May 2002. [44] The last annual conference on climate change took place in Madrid in December 2019. [45]
On 23 March 2023, Teresa Ribera, Vice President of the Spanish Government, and Fatih Birol, International Executive Director of the International Energy Agency, announced Madrid will host an international climate and energy summit on 2 October 2023. The goal of the summit is to build a coalition to maintain the commitment reached in the Paris agreement—limiting the global temperature increase to below 1.5 °C (2.7 °F). [46]
According to the IEA, global CO2 emissions need to peak before 2025, and drop to net zero by 2050, to prevent global temperatures from rising by more than 1.5 °C (2.7 °F). The summit is confirmation of the Paris agreement and will be useful to provide global decision-makers with the opportunity to send a signal of strength for our common future. [46]
In the words of Fatih Birol, the meeting in Madrid will be "the moment to come together in a grand coalition of all stakeholders – encompassing governments, the energy industry, investors and civil society – that are genuinely committed to reducing emissions while safeguarding energy security. We need to send a strong message ahead of COP28 that the 1.5 °C goal is still alive." [46]
As the effects of climate change are being felt more in Spain than in central and northern European countries, Spanish society is more concerned about climate change than countries traditionally considered environmentalist such as Germany or Sweden. [8]
In Spain 82% of people think that climate change is the biggest challenge for humanity in the 21st century. Furthermore, 81% of Spanish people believe that climate change has an impact on their lives, versus 77% of Europeans in general. A majority of Spanish people also believe that their country should rely more on renewable energies. [9]
Spanish people also think that the governmental measures are too flexible and that they allow individuals and companies to avoid changing their behaviour. Therefore 58% of Spanish people think that Spain will not succeed in reducing greenhouse gas emissions as set out in the Paris agreement. [9]
Among the most popular Spanish solutions against climate change are: educating and improving children's concern for sustainable consumption; the creation of a specific tax for those products and services that contribute the most to climate change; and eliminating short-haul flights, instead promoting high-speed trains. [9]
Climate movements in Spain are growing especially among the youth. A slogan used by a wide range of civil society groups including climate activists, workers' unions and fair housing movements is that "without sustainability there is no social justice." [47]
Spanish environmental activists have spoken out against plans to expand airports in Madrid and Barcelona; the organisers of these protests have united around a platform called Zeroport. [47]
The Fridays for Future movement has also become very popular in Spain. The first demonstration took place at the University of Girona and quickly spread to the rest of the country. [48]
In 2019, half a million people took to the streets because of climate change. [47]
An emission intensity is the emission rate of a given pollutant relative to the intensity of a specific activity, or an industrial production process; for example grams of carbon dioxide released per megajoule of energy produced, or the ratio of greenhouse gas emissions produced to gross domestic product (GDP). Emission intensities are used to derive estimates of air pollutant or greenhouse gas emissions based on the amount of fuel combusted, the number of animals in animal husbandry, on industrial production levels, distances traveled or similar activity data. Emission intensities may also be used to compare the environmental impact of different fuels or activities. In some case the related terms emission factor and carbon intensity are used interchangeably. The jargon used can be different, for different fields/industrial sectors; normally the term "carbon" excludes other pollutants, such as particulate emissions. One commonly used figure is carbon intensity per kilowatt-hour (CIPK), which is used to compare emissions from different sources of electrical power.
Climate change mitigation (or decarbonisation) is action to limit the greenhouse gases in the atmosphere that cause climate change. Greenhouse gas emissions are primarily caused by people burning fossil fuels such as coal, oil, and natural gas. Phasing out fossil fuel use can happen by conserving energy and replacing fossil fuels with clean energy sources such as wind, hydro, solar, and nuclear power. Secondary mitigation strategies include changes to land use and removing carbon dioxide (CO2) from the atmosphere. Governments have pledged to reduce greenhouse gas emissions, but actions to date are insufficient to avoid dangerous levels of climate change.
Greenhouse gas (GHG) emissions from human activities intensify the greenhouse effect. This contributes to climate change. Carbon dioxide, from burning fossil fuels such as coal, oil, and natural gas, is one of the most important factors in causing climate change. The largest emitters are China followed by the United States. The United States has higher emissions per capita. The main producers fueling the emissions globally are large oil and gas companies. Emissions from human activities have increased atmospheric carbon dioxide by about 50% over pre-industrial levels. The growing levels of emissions have varied, but have been consistent among all greenhouse gases. Emissions in the 2010s averaged 56 billion tons a year, higher than any decade before. Total cumulative emissions from 1870 to 2022 were 703 GtC, of which 484±20 GtC from fossil fuels and industry, and 219±60 GtC from land use change. Land-use change, such as deforestation, caused about 31% of cumulative emissions over 1870–2022, coal 32%, oil 24%, and gas 10%.
Greenhouse gas emissions by Australia totalled 533 million tonnes CO2-equivalent based on greenhouse gas national inventory report data for 2019; representing per capita CO2e emissions of 21 tons, three times the global average. Coal was responsible for 30% of emissions. The national Greenhouse Gas Inventory estimates for the year to March 2021 were 494.2 million tonnes, which is 27.8 million tonnes, or 5.3%, lower than the previous year. It is 20.8% lower than in 2005. According to the government, the result reflects the decrease in transport emissions due to COVID-19 pandemic restrictions, reduced fugitive emissions, and reductions in emissions from electricity; however, there were increased greenhouse gas emissions from the land and agriculture sectors.
Climate change has received significant scientific, public and political attention in Sweden. In 1896, Swedish chemist Svante Arrhenius was the first scientist to quantify global heating. Sweden has a high energy consumtion per capita, but reducing the dependency on fossil energy has been on the agenda of cabinets of the Governments of Sweden since the 1970s oil crises. In 2014 and 2016, Sweden was ranked #1 in the Global Green Economy Index (GGEI), because the Swedish economy produces relatively low emissions. Sweden has had one of the highest usages of biofuel in Europe and aims at prohibiting new sales of fossil-cars, including hybrid cars, by 2035, and for an energy supply system with zero net atmospheric greenhouse gas emissions by 2045.
Primary energy consumption in Spain in 2020 was mainly composed of renewable sources. The largest sources are petroleum (42.3%), natural gas (19.8%) and coal (11.6%). The remaining 26.3% is accounted for by nuclear energy (12%) and different renewable energy sources (14.3%). Domestic production of primary energy includes nuclear (44,8%), solar, wind and geothermal (22,4%), biomass and waste (21,1%), hydropower (7,2%) and fossil (4,5%).
Energy in Portugal describes energy and electricity production, consumption and import in Portugal. Energy policy of Portugal will describe the politics of Portugal related to energy more in detail. Electricity sector in Portugal is the main article of electricity in Portugal.
Climate change has far reaching impacts on the natural environment and people of Finland. Finland was among the top five greenhouse gas emitters in 2001, on a per capita basis. Emissions increased to 58.8 million tonnes in 2016. Finland needs to triple its current cuts to emissions in order to be carbon neutral by 2035. Finland relies on coal and peat for its energy, but plans to phase out coal by 2029. Finland has a target of carbon neutrality by the year 2035 without carbon credits. The policies include nature conservation, more investments in trains, changes in taxation and more sustainable wood burning. After 2035 Finland will be carbon negative, meaning soaking more carbon than emitting.
Climate change has resulted in an increase in temperature of 2.3 °C (2022) in Europe compared to pre-industrial levels. Europe is the fastest warming continent in the world. Europe's climate is getting warmer due to anthropogenic activity. According to international climate experts, global temperature rise should not exceed 2 °C to prevent the most dangerous consequences of climate change; without reduction in greenhouse gas emissions, this could happen before 2050. Climate change has implications for all regions of Europe, with the extent and nature of impacts varying across the continent.
Climate change is leading to long-term impacts on agriculture in Germany, more intense heatwaves and coldwaves, flash and coastal flooding, and reduced water availability. Debates over how to address these long-term challenges caused by climate change have also sparked changes in the energy sector and in mitigation strategies. Germany's energiewende has been a significant political issue in German politics that has made coalition talks difficult for Angela Merkel's CDU.
In France, climate change has caused some the greatest annual temperature increases registered in any country in Europe. The 2019 heat wave saw record temperatures of 46.0 °C. Heat waves and other extreme weather events are expected to increase with continued climate change. Other expected environmental impacts include increased floods due to both sea level rise and increased glacier melt. These environmental changes will lead to shifts in ecosystems and affect local organisms. Climate change will also cause economic losses in France, particularly in the agriculture and fisheries sectors.
Climate change is having a considerable impact in Malaysia. Increasing temperatures are likely to greatly increase the number of heatwaves occurring annually. Variations in precipitation may increase the frequency of droughts and floods in various local areas. Sea level rise may inundate some coastal areas. These impacts are expected to have numerous environmental and socioeconomic effects, exacerbating existing environmental issues and reinforcing inequality.
The climate of Greece is changing by way of increased drought, flooding, wildfires and sea level rise. These extreme weather conditions are likely to become more frequent and as a result landscapes and biodiversity will be affected. Climate change will also cause human activities such as land-use change, urbanisation and soil degradation to further affect Greek's ecosystems. Ecosystems in Greece are already at their tipping point, close to their environmental limits. Policies and laws have been put in place by the Greek government to try to manage these issues.
In Italy, widespread impacts of climate change are currently being felt. With an increase in extreme events such as heatwaves, droughts and more frequent flooding, Italy faces many challenges adapting to climate change.
India is ranked fourth among the list of countries most affected by climate change in 2015. India emits about 3 gigatonnes (Gt) CO2eq of greenhouse gases each year; about two and a half tons per person, which is less than the world average. The country emits 7% of global emissions, despite having 17% of the world population. Temperature rises on the Tibetan Plateau are causing Himalayan glaciers to retreat, threatening the flow rate of the Ganges, Brahmaputra, Yamuna and other major rivers. A 2007 World Wide Fund for Nature (WWF) report states that the Indus River may run dry for the same reason. Heat waves' frequency and intensity are increasing in India because of climate change. Severe landslides and floods are projected to become increasingly common in such states as Assam. The climate change performance index of India ranks eighth among 63 countries which account for 92% of all GHG emissions in the year 2021.
China's greenhouse gas emissions are the largest of any country in the world both in production and consumption terms, and stem mainly from coal burning, including coal power, coal mining, and blast furnaces producing iron and steel. When measuring production-based emissions, China emitted over 14 gigatonnes (Gt) CO2eq of greenhouse gases in 2019, 27% of the world total. When measuring in consumption-based terms, which adds emissions associated with imported goods and extracts those associated with exported goods, China accounts for 13 gigatonnes (Gt) or 25% of global emissions.
Climate change in the Middle East and North Africa (MENA) refers to changes in the climate of the MENA region and the subsequent response, adaption and mitigation strategies of countries in the region. In 2018, the MENA region emitted 3.2 billion tonnes of carbon dioxide and produced 8.7% of global greenhouse gas emissions (GHG) despite making up only 6% of the global population. These emissions are mostly from the energy sector, an integral component of many Middle Eastern and North African economies due to the extensive oil and natural gas reserves that are found within the region. The region of Middle East is one of the most vulnerable to climate change. The impacts include increase in drought conditions, aridity, heatwaves and sea level rise.
The Netherlands is already affected by climate change. The average temperature in the Netherlands rose by more than 2 °C from 1901 to 2020. Climate change has resulted in increased frequency of droughts and heatwaves. Because significant portions of the Netherlands have been reclaimed from the sea or otherwise are very near sea level, the Netherlands is very vulnerable to sea level rise.
World energy supply and consumption refers to the global supply of energy resources and its consumption. The system of global energy supply consists of the energy development, refinement, and trade of energy. Energy supplies may exist in various forms such as raw resources or more processed and refined forms of energy. The raw energy resources include for example coal, unprocessed oil & gas, uranium. In comparison, the refined forms of energy include for example refined oil that becomes fuel and electricity. Energy resources may be used in various different ways, depending on the specific resource, and intended end use. Energy production and consumption play a significant role in the global economy. It is needed in industry and global transportation. The total energy supply chain, from production to final consumption, involves many activities that cause a loss of useful energy.
Israel, like many other countries in the Middle East and North Africa, experience adverse effects from climate change. Annual and mean temperatures are increasing in Israel, with mean temperature expected to increase between 1.6 and 1.8 °C by 2100. There is a reduction in annual precipitation and delayed winter rains. Israel is already experiencing droughts and water shortages. Heatwaves are other natural hazards expected to increase with climate change.
Medium-range estimates of Arctic carbon emissions could result from moderate climate emission mitigation policies that keep global warming below 3°C (e.g., RCP4.5). This global warming level most closely matches country emissions reduction pledges made for the Paris Climate Agreement...
"The IPCC doesn't make projections about which of these scenarios is more likely, but other researchers and modellers can. The Australian Academy of Science, for instance, released a report last year stating that our current emissions trajectory had us headed for a 3°C warmer world, roughly in line with the middle scenario. Climate Action Tracker predicts 2.5 to 2.9°C of warming based on current policies and action, with pledges and government agreements taking this to 2.1°C.
