This is despite a fall in global energy-related CO2 emissions of 5.8% in 2020 due to restrictions related to the coronavirus (COVID-19) pandemic (See chapter: Global Greenhouse Gas Emissions and Budgets). Zachariah, M., et al., 2022. This is 4 GtCO2e lower than the median estimate of the 2020 Emissions Gap Report (UNEP, 2020) and 9 GtCO2e lower than the 2010-policies scenario, which illustrates how global emissions would evolve had there been no new climate policies since 2010. The majority are furthermore unclear or undecided on the inclusion of emissions from international aviation and shipping and the use of international offsets. This production of methane is a rather complicated process, requiring a highly reducing environment (Eh 350 to 450 mV) and a pH between 6 and 8, as well as a complex syntrophic, consortia of different varieties of archaea and bacteria. Data-Driven EnviroLab, Global climate action from cities, regions and businesses. Measures which reduce the risk of hydrate formation include: At sufficient depths, methane complexes directly with water to form methane hydrates, as was observed during the Deepwater Horizon oil spill in 2010. [50] (Kicks, which can cause blowouts, typically do not involve hydrates: see Blowout: formation kick). the fresh water Lake Baikal, Siberia. However, some methane clathrates deposits in the Arctic are much shallower than the rest, which could make them far more vulnerable to warming. Extreme heat also affected Central Europe and the broader Mediterranean region where Syracuse in Sicily, Italy, reached 48.8 C. This includes many European countries as well as Japan, Mexico, and the United States of America. WMO is currently exploring the possibility of developing an internationally coordinated, operational Global Greenhouse Monitoring Infrastructure to observe and model GHG concentrations in the atmosphere and the relevant fluxes between atmosphere, land, and oceans. They may cap even larger deposits of gaseous methane. At a time when urgent action to address climate change is needed, the report provides unified scientific information to inform decision-makers and highlights some of the physical and socioeconomic impacts of the current and projected climate. Figure 2. Early warning systems can save lives, reduce losses and damages, contribute to disaster risk reduction, and support climate change adaptation. In the other four cases, the NDCs lead to emissions in 2030 that are about 25%95% higher than a linear path towards their net-zero targets would imply. As a result, the water depth got shallower with less hydrostatic pressure, without further warming. Figure 2 provides an example in New York City, which focuses on tracking resiliency indicators and monitoring over time. Most of the excess energy that accumulates in the Earth system due to increasing concentrations of GHGs is taken up by the ocean. However, less than half of all countries in the world have these crucial systems and coverage is particuarly low in vulnerable countries. Contribution of Working Group I to the Third Assessment Report of the Intergovernmental Panel on Climate Change, edited by J.T. Local variations may be widespread since the act of forming hydrate, which extracts pure water from saline formation waters, can often lead to local and potentially significant increases in formation water salinity. 417470, Cambridge University Press, 2001. Contribution of Working Group II to the Sixth Assessment Report of the Intergovernmental Panel on Climate Change [H.-O. Prtner, D.C. Roberts, E.S. Loutre, D. McGee, K. Rehfeld, R. Rhodes, A.W.R. In 2021, the spotlight was on the implication of new or updated climate mitigation pledges for 2030, the status of net-zero emissions pledges and pathways, and the estimated global warming at the end of the century under current policies, pledges and scenarios. Skill is low to medium for these regions, giving low to medium confidence. Desbruyeres, E. Frajka-Williams, B. Moat, and J. Robson, 2022: The evolution of the North Atlantic Meridional Overturning Circulation since 1980. Photo WMO/Agusti Descarrega Sola). Tropical regions, such as Amazonia, play an important role in the global carbon budget. Mallett, R. D. C.; Stroeve, J. C.; Cornish, S. B. et al., 2021: Record winter winds in 2020/21 drove exceptional Arctic sea ice transport. Additionally, a coinciding marine heatwave led to devastating consequences for marine life and an extended drought across large parts of Europe impacted freshwater and other aquatic ecosystems through low river waters, plant stress and forest fires. Urban areas can create opportunities to increase resource efficiency and significantly reduce GHG emissions through the systemic transition of infrastructure and urban form through low-emission development pathways towards net-zero emissions (IPCC Working Group III, 2022). [1][2][3][4] [5] Originally thought to occur only in the outer regions of the Solar System, where temperatures are low and water ice is common, significant deposits of methane clathrate have been found under sediments on the ocean floors of the Earth. These occur in Alaska, Siberia, and Northern Canada. Science, 367, 13311335. The Plot in You have released one EP and five studio albums. However, the full socioeconomic benefits of MHEWS are likely to be underestimated as some benefits are difficult to monetize, such as potential lives saved. Lenton, M. Barton, R.M. These conditions are leading to increasing global surface temperature and other climatic changes, as highlighted by the WMO State of the Global Climate 2021 report, which found the most recent seven years, 2015 to 2021, to be the warmest on record. Nature Climate Change, 12, 499503. Pal, J.S., and E.A.B. Poloczanska, K. Mintenbeck, M. Tignor, A. Alegra, M. Craig, S. Langsdorf, S. Lschke, V. Mller, A. Okem (eds.)]. Amazonia hosts the Earths largest tropical forest, but only has a few of the in situ observations needed to monitor large-scale carbon fluxes, as is the case with other tropical regions. Animal Conservation, 22, 386395, 2019. Once formed, hydrates can block pipeline and processing equipment. Yet, many developing countries still lack such systems. Web6 environmental wins that gave us hope in 2022. It is known that larger hydrocarbon molecules like ethane and propane can also form hydrates, although longer molecules (butanes, pentanes) cannot fit into the water cage structure and tend to destabilise the formation of hydrates. Guiot, J., and W. Cramer, 2016: Climate Change: The 2015 Paris Agreement thresholds and Mediterranean basin ecosystems. Contribution of Working Group I to the Fifth Assessment Report of the Intergovernmental Panel on Climate Change, edited by T.F. [80], Research by Klaus Wallmann et al. Total net anthropogenic GHG emissions have continued to rise during the period 20102019 (IPCC Working Group III, 2022), Average annual GHG emissions during 20102019 were higher than in any previous decade, but the rate of growth between 2010 and 2019 was lower than that between 2000 and 2009 (IPCC Working Group III, 2022). It is interlinked with existing critical infrastructure issues, financial constraints and systemic inequities. Controlling TUBE AMPS From Your Computer? 33115, Cambridge University Press, Cambridge, United Kingdom and New York, NY, USA, 2013. In coastal cities, the combination of more frequent extreme sea level events (due to sea level rise and storm surge) and extreme rainfall/riverflow events will make flooding more probable (high confidence) (IPCC Working Group I, 2021), Interactions between changing urban form, exposure and vulnerability can create climate change-induced risks and losses for cities and settlements. Moog on your desktop it's happening and you can get it right now. Thresholds and tipping points may be increasingly encountered in regional weather patterns and extremes with consequences for local communities and ecosystem services (Drought and developing storm in the Ebro Delta, Spain, 2020. The project has already reached injection phase and was analyzing resulting data by March 12, 2012. Brovkin, V., E. Brook, J.W. The latest IPCC report has assessed tipping points and outlines the limits of the current status of knowledge. I urge all leaders to heed the facts in this report, to unite behind the science and to take ambitious urgent climate action. Their tipping would be particularly dangerous as they would have global consequences due to substantial additional sea-level rise on the timescales of centuries to millennia (Clark et al., 2016). The Russian Federation had its coldest winter since 2009/2010 and below-average temperatures affected much of Japan in late December and early January. Note that the Paris Agreement level of 1.5 C refers to long-term warming, but individual years above 1.5 C are expected to occur with increasing regularity as global temperatures approach this long-term threshold. In recent years, development of other forms of hydrate inhibitors have been developed, like Kinetic Hydrate Inhibitors (increasing the required sub-cooling which hydrates require to form, at the expense of increased hydrate formation rate) and anti-agglomerates, which do not prevent hydrates forming, but do prevent them sticking together to block equipment. Cities, supported by networks such as the Urban Climate Change Research Network (UCCRN), the Global Covenant of Mayors (GCoM), C40, the International Council for Local Environmental Initiatives (ICLEI), United Cities and Local Governments (UCLG), and others, can effectively develop the managerial and governance capacity needed to fulfil climate action stock takes under the requirements of the Paris Climate Agreement and SDG 11: Sustainable Cities and Communities. This is about 5 GtCO2e lower than the gap assessed in the 2020 report (UNEP, 2020), due to the updated NDCs and announced mitigation pledges. The science is clear urgent action is needed to mitigate emissions and adapt to our changing climate. With 3.3 to 3.6 billion people living in contexts that are highly vulnerable to climate change (IPCC, 2022), it is more important than ever for the international community to take ambitious action to not only mitigate emissions, but also adapt to climate change, particularly extreme weather and compounding events, which can lead to long-lasting socioeconomic impacts. Additionally, the Intergovernmental Panel on Climate Change (IPCC) recently released highly anticipated Working Group reports covering The Physical Science Basis; Impacts, Adaptation and Vulnerability; and Mitigation of Climate Change, which are an integral part of its Sixth Assessment Report. Oh wait, I'm supposed to believe man made climate change. Or sneak into in the dead of night. Worthington, E.L., B.I. "[43] Japan estimates that there are at least 1.1 trillion cubic meters of methane trapped in the Nankai Trough, enough to meet the country's needs for more than ten years. Milne, P.L. I should add his type of restaurant doesnt serve snow crab, but I know for a fact this time last year their King crab amd lobster tail prices went through the roof almost overnight. But where sedimentation rates and the organic carbon content are high, which is typically the case on continental shelves and beneath western boundary current upwelling zones, the pore water in the sediments becomes anoxic at depths of only a few centimeters or less. In addition, deep fresh water lakes may host gas hydrates as well, e.g. Based on a new accounting of land-use GHG emissions from agriculture and land-use change, a new analysis shows that emissions from trade in food were 5.8 gigatons of CO2 equivalent (GtCO2e) in 2017, representing 27% of GHG emissions from land-use change (Hong et al., 2022). Island Press, Washington, D.C., USA, 269300. Abalone shells were also traded along routes starting in southern California and reaching east of the Mississippi River. [42] Previously, gas had been extracted from onshore deposits, but never from offshore deposits which are much more common. Geophysical Research Letters, 47, 10.1029/2019GL086075. According to the Urban Climate Change Research Network, cities responsible for up to 70% of human-caused emissions will face increasing climate impacts that will intersect with socioeconomic inequalities. Politics-Govt Just in time for U.S. Senate race, border wall gets a makeover. Multi-Hazard Early Warning Systems (MHEWS) integrate hazard information with risk analysis to provide meaningful early warnings that allow governments, communities, and individuals to understand the risks related to impending events and to act to minimize impacts. Although final global average figures for 2021 are not yet available, the data indicates that the anthropogenic CO2 emissions led to a continued increase in global atmospheric CO2 concentrations. The varied nature of the extreme rainfall, with some areas experiencing persistent heavy rain for several days and others receiving short but very intense rain, makes defining how the event may be connected to human-caused climate change challenging. Stuff goes in cycles. Antarctic sea-ice extent increased slowly from the start of the satellite era to around 2015, as can be seen in Figure 4. Thornalley, N. Cahill, and S. Rahmstorf, 2021: Current Atlantic Meridional Overturning Circulation weakest in last millennium. Abnormally cold conditions affected many parts of the central United States and northern Mexico in mid-February 2021. The rapid release of methane gas in a closed system can result in a rapid increase in pressure.[9]. Overall, analysis reveals that ambition of new pledges would need to be four times higher to get on track to 2 C and seven times higher to get on track to 1.5 C. The methane in gas hydrates is dominantly generated by microbial consortia degrading organic matter in low oxygen environments, with the methane itself produced by methanogenic archaea. Globally, by the 2050s, over 1.6 billion people living in over 970 cities will be regularly exposed to 3-month average temperatures reaching at least 35 C (95 F) (Rosenzweiget al., 2021).

An example of this is the dust bowl period in the United States (e.g., Cowan et al., 2020). Around 90% of the accumulated heat in the Earth system is stored in the ocean, which is measured through Ocean Heat Content.

Additionally, the WMO World Weather Research Programme highlights that it is the worlds most vulnerable populations that will suffer the most, as has already been observed during recent extreme weather events. OUR U.S. STORE REMAINS OPEN AND SHIPS WORLDWIDE. It's so expensive I've never tried it. [92] A recent study has demonstrated that SNG can be formed directly with seawater instead of pure water in combination with THF.[93]. [43] According to an industry spokesperson, "It [was] the world's first offshore experiment producing gas from methane hydrate". They need to over step the federal government and ban foreign countries from fishing and taking shell fish from Alaska waters. Loss of the Amazon rainforest would have potentially devastating consequences on regional climate, biodiversity and social systems as well as potentially wider impacts through changes of the hydrological and carbon cycles. Stocker). Measurements of the layer from the surface to a 700 metre (m) depth show that the 20182022 global heat content (data to May 2022) was higher than in any previous year (Figure 3). Stocker, T.F., et al., Technical Summary, in Climate Change 2013: The Physical Science Basis. Pattyn, F., et al., 2018: The Greenland and Antarctic ice sheets under 1.5 C global warming. [18]:9, These deposits are located within a mid-depth zone around 300500 m thick in the sediments (the gas hydrate stability zone, or GHSZ) where they coexist with methane dissolved in the fresh, not salt, pore-waters. Science, 365, eaaw6974. What we now refer to collectively as tipping points in the climate system were first addressed in the Third Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) as surprises (Stocker et al., 2001) and subsumed under the Reasons for Concern as large-scale singular events or discontinuities in the climate system (IPCC, 2001). November 29 0. The observed density is around 0.9 g/cm3, which means that methane hydrate will float to the surface of the sea or of a lake unless it is bound in place by being formed in or anchored to sediment. The sedimentary methane hydrate reservoir probably contains 210 times the currently known reserves of conventional natural gas, as of 2013[update]. The science is unequivocal: we are going in the wrong direction. (This was a matrilineal kinship system, with social status passed through the female lines.) However, the global trend of urbanization also offers a critical opportunity in the near-term, to advance climate resilient development (high confidence) (IPCC Working Group II, 2022). The gas hydrates may then flow upward with drilling mud or other discharged fluids. Gas hydrate pingos have been discovered in the Arctic oceans Barents sea. Enhanced action is needed to prevent the continued warming that is increasing the likelihood of irreversible changes in the climate system, known as tipping points, Billions of people around the world are exposed to climate change impacts. The storms caused severe humanitarian impacts across the region one of the poorest and most vulnerable in the world. MacDowell, D.J. This years United in Science report shows that we are way off track. Their first four albums are considered to be deathcore, but their fifth album, Matriarch, is considered to be metalcore. The elderly and people with chronic health conditions are particularly vulnerable, but other factors such as socioeconomic conditions, work conditions, urbanization, and levels of preparedness can also increase vulnerability. Prop 30 is supported by a coalition including CalFire Firefighters, the American Lung Association, environmental organizations, electrical workers and businesses that want to improve Californias air quality by fighting and preventing wildfires and reducing air pollution from vehicles. The resulting violent expulsion of fluid from the annulus is one potential cause or contributor to the "kick". Co-generation of knowledge and research while working with stakeholders is crucial to create usable climate data at the city level. [43] The hydrate field from which the gas was extracted is located 50 kilometres (31mi) from central Japan in the Nankai Trough, 300 metres (980ft) under the sea. There is a 93% probability that at least one year in the next five will be warmer than the warmest year on record (2016) and that the mean temperature for 20222026 will be higher than that of the last five years. There are a range of adaptation options, such as disaster risk management, early warning systems, climate services and risk spreading and sharing that have broad applicability across sectors and provide greater benefits to other adaptation options when combined (high confidence) (IPCC Working Group II, 2022). Poloczanska, K. Mintenbeck, A. Alegra, M. Craig, S. Langsdorf, S. Lschke, V. Mller, A. Okem, B. Rama (eds.)]. In London, for example, the urban heat island made the city significantly warmer than surrounding areas and high levels of inequality exacerbated vulnerability (Zachariah et al., 2022). Breshears, D.D., H.D. Urbanization also increases mean and heavy precipitation over and/or downwind of cities (medium confidence) and resulting runoff intensity (high confidence). They also found that during storms, when wind accelerates air-sea gas exchange, methane levels in the water column drop dramatically. Cheng, L., Abraham, J., Trenberth, K.E. While the underlying physical mechanisms are well-researched and theoretically understood, determination of the critical thresholds for the individual ice basins under realistic conditions and topography is very difficult, and large uncertainties remain (Pattyn and Morlighem, 2020). by Gear Gods. Examples include thinning of 1.52 m per year in New Zealand, 1.24 m per year in Alaska, 1.11 m per year in Central Europe, and 1.05 m per year in Western North America (not including Alaska). However, it dropped rapidly between 2015 and 2017, then returned close to the long-term average between 2017 and 2021 before reaching its lowest or second lowest minimum on record, according to different data sources from February 2022. [40] The University of Bergen's method is being field tested by ConocoPhillips and state-owned Japan Oil, Gas and Metals National Corporation (JOGMEC), and partially funded by the U.S. Department of Energy. In: Climate Change 2022: Impacts, Adaptation and Vulnerability. However, it too is depleted by a depth of centimeters to meters. Climate resiliency should be central in every financial decision that cities and their metropolitan regions make. Contribution of Working Group III to the Sixth Assessment Report of the Intergovernmental Panel on Climate Change [P.R. Atmospheric greenhouse gas concentrations continue to rise and fossil fuel emissions are now above pre-pandemic levels after a temporary drop due to lockdowns associated with the COVID-19 pandemic in 2020 and 2021, Recent years saw record high temperatures and ocean heat. Average 9-year monthly means of ALF carbon flux (20102018). However, it is only archaea that actually emit methane. Science, 354, 465468. Tipping points have become a widely-used shorthand for many aspects of non-linear changes in a complex system. [6] Methane hydrate is formed when hydrogen-bonded water and methane gas come into contact at high pressures and low temperatures in oceans. (eds. al., 2022). The emissions gap in 2030 (Figure 2) highlights that while the new and updated mitigation pledges narrow the gap slightly compared to previous pledges, they are highly insufficient to bridge the gap. These tipping points have both global and regional consequences and include changes in the Atlantic Meridional Overturning Circulation (AMOC), the melting of polar ice sheets, the migration of large-scale weather and climate patterns, and dieback of the Amazon rainforest. High flow-rates, which limit the time for hydrate formation in a volume of fluid, thereby reducing the kick potential. The increase in CO2 from 2019 to 2020 was slightly lower than that observed from 2018 to 2019, but higher than the average annual growth rate over the last decade. However, this range was reassessed and found to be at or slightly above 1.5 to 2 C that is, the global warming limits of the Paris Agreement (Pattyn et al., 2018). Only 10 G20 members (Argentina, China, EU27, India, Japan, the Russian Federation, Saudi Arabia, South Africa, Trkiye and the United Kingdom) are on track to achieve their previous NDCs. There is an almost 50% likelihood that at least one of the years from 20222026 will temporarily exceed warming of 1.5 C above pre-industrial levels (18501900 average), There is a 93% probability that at least one year between 2022 and 2026 will be warmer than the warmest year on record (2016) and that the five-year mean temperature for 20222026 will be higher than that for 20172021. Meanwhile, other parts of the world suffered from drought. If the sedimentation rate is low (about 1 cm/yr), the organic carbon content is low (about 1% ), and oxygen is abundant, aerobic bacteria can use up all the organic matter in the sediments faster than oxygen is depleted, so lower-energy electron acceptors are not used. Nature Climate Change, 11, 680688. The National Inventory Report, which tracks progress against emissions targets under the United Nations Framework Convention on Climate Change (UNFCCC), uses measurements of tree diameter and height at a national network of sites to estimate forest carbon uptake (New Zealand Ministry for the Environment, 2021). Although understanding broad-scale changes in the climate is important, the acute impacts of weather and climate are most often felt during extreme meteorological events such as heavy rain and snow, droughts, heatwaves, cold waves, and storms, including tropical storms and cyclones. The United Nations system, along with its partners, will continue to provide world-leading science to inform decision-making and support global climate action. [57] Clathrate deposits destabilize from the deepest part of their stability zone, which is typically hundreds of metres below the seabed. In 2021 the Global Basic Observing Network (GBON) was established, committing all countries to generate and exchange basic weather and climate data. Weijer, W., W. Cheng, O.A. et al., 2022: Emissions rebound from the Covid-19 pandemic. USGS Digital Data Series DDS-60. A growing number of countries are initiating programs to merge observation-based emission information with activity and emission-factor based estimates. Shop Limited Edition and exclusive products. Cowan, T., G.C. Collectively, countries are falling short of meeting their new or updated pledges with the policies that are currently being implemented. The WCRP, for example, is addressing this issue in one of their Lighthouse Activities through an international platform to combine theoretical-mathematical approaches, observational moni-toring, and comprehensive climate modelling efforts. Zou, 2020: The critical amplifying role of increasing atmospheric moisture demand on tree mortality and associated regional die-off. Alaska cancels snow crab season, threatening key economic driver Scientists are still evaluating the cause or causes of the snow crab collapse after a stretch of record-breaking warmth in Bering Sea waters spiked in 2019. Several studies demonstrate consistently high returns and provide a strong economic rationale for investments into MHEWS. Increases in frequency of extreme rainfall and heavy downpour events are already causing more frequent flooding of inland coastal cities. The remaining new or updated pledges submitted in 2022 will have limited effects on global emissions projections. Western Europe experienced some of its most severe flooding on record in mid-July 2021. echo do_shortcode('[mkdf_block_two number_of_posts="3" block_proportion="two_third_one_third" category_id="50" author_id="0" featured_thumb_image_size="custom_size" featured_display_post_type_icon="yes" thumb_image_size="custom_size" display_post_type_icon="yes" display_pagination="no" featured_thumb_image_width="856" featured_thumb_image_height="585" thumb_image_width="417" thumb_image_height="280"]'); According to WMO and the UN Office for Disaster Risk Reduction (UNDRR), early warning systems not only save lives and reduce losses and damages, but also contribute to disaster risk reduction, and support climate change adaptation. This page was last edited on 16 October 2022, at 16:51 (UTC). As attribution science continues to improve, evidence of the link between human-induced climate change and observed extremes, such as heatwaves, heavy precipitation and tropical cyclones, has strengthened (IPCC 2021). https://www.worldweatherattribution.org/wp-content/uploads/India_Pak-Hea https://publications.iadb.org/publications/english/document/Impact_of_Hu https://www.dwd.de/DE/leistungen/besondereereignisse/duerre/20220706_tro https://www.dwd.de/DE/wetter/thema_des_tages/2022/7/21.html. This implies that every US$ 1 invested in early warning systems could result, on average, in US$ 9 in net economic benefits. 6198, https://uccrn.ei.columbia.edu/sites/default/files/content/pubs/ARC3.2-PD Hsu, A., et al., 2021: Disproportionate exposure to urban heat island intensity across major US cities. Nature Communications, 11, 2870. Care must be taken to ensure that the removal of the hydrates is carefully controlled, because of the potential for the hydrate to undergo a phase transition from the solid hydrate to release water and gaseous methane at a high rate when the pressure is reduced. It is known to separate the "Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the We need a renewable energy revolution to bring down carbon emissions. A first necessary step, which is both quick and cost-effective, is early warning. The rapid gas expansion ejects fluid from the well, reducing the pressure further, which leads to more hydrate dissociation and further fluid ejection. Even though all modern cetaceans are obligate aquatic mammals, early cetaceans were amphibious, and their ancestors were terrestrial artiodactyls, similar to small deer. However, there is only a small probability (10%) that the five-year mean will exceed this threshold. So much for all-you-can-eat crab coming back to the casino buffets. Wow this is super bad news for restaurants like the one my DH works at. For example, in the devastated town of Lismore, marginalized Aboriginal communities were particularly hard hit as well as lower-income families who are more likely to live in flood-prone locations and to be unable to afford flood insurance (Williamson, 2022). Additionally, there is a 93% chance that at least one year in the same time period will be the hottest on record. Cities responsible for up to 70% of human-caused emissions will face increasing socioeconomic impacts and the worlds most vulnerable populations will suffer most, as seen in recent extreme weather events. Contribution of Working Group III to the Sixth Assessment Report of the Intergovernmental Panel on Climate Change [P.R. Preliminary analysis of the data from a subset of the GAW GHG observational network demonstrated that CO2 concentrations exceeded 410 parts per million (ppm) during the whole of 2021. Microsoft pleaded for its deal on the day of the Phase 2 decision last month, but now the gloves are well and truly off. Effect of hydrate phase transition during deep water drilling, Natural gas hydrates for gas storage and transportation, The average methane clathrate hydrate composition is 1. Despite a strong fluctuation in global emissions over the past 2.5 years, fossil CO2 emissions significantly decreased in 23 countries, accounting for about one quarter of global emissions (9 GtCO2 yr-1), during the pre-pandemic decade of 20102019.
