Esta agua sobrante podría hacer que aumente considerablemente el nivel del mar. Note that the 5–95% intervals often quoted in square brackets in AR5 correspond to very likely ranges, while likely ranges correspond to 17–83%, or the central two-thirds, of the distribution of uncertainty. 5. 28th Annual Conference of the International Group for Lean Construction (IGLC). Adaptation can be incremental, or transformational, meaning fundamental attributes of the system are changed (Chapter 3 and 4). Beginning in 2013 and ending at the COP21 in Paris in 2015, the first review period of the long-term global goal largely consisted of the Structured Expert Dialogue (SED). Allan, W.J. For ambitious mitigation goals, and under conditions of rapid warming or declining sea ice (Berger et al., 2017)59, the difference can be significant. Specifically, warming at a given point in time is defined as the global average of combined land surface air and sea surface temperatures for a 30-year period centred on that time, expressed relative to the reference period 1850–1900 (adopted for consistency with Box SPM.1 Figure 1 of IPCC (2014a)53 ‘as an approximation of pre-industrial levels’, excluding the impact of natural climate fluctuations within that 30-year period and assuming any secular trend continues throughout that period, extrapolating into the future if necessary. Estimates of the warming commitment from eliminating aerosol emissions are affected by large uncertainties in net aerosol radiative forcing (Myhre et al., 2013, 2017)166 and the impact of other measures affecting aerosol loading (e.g., Fernández et al., 2017)167. (2018)63 show that this is primarily an issue for the interpretation of the historical record to date, with less absolute impact on projections of future changes, or estimated emissions budgets, under ambitious mitigation scenarios. Matthews, 2016: On the proportionality between global temperature change and cumulative CO. Bowerman, N.H.A., D.J. This schematic assumes for the purposes of illustration that the fractional contribution of non-CO2 climate forcers to total anthropogenic forcing (which is currently increasing, Myhre et al., 2017)112 is approximately constant from now on. A fin de comprender mejor el impacto del hombre en el sistema climático, compartimos otros datos impactantes: - Algunos de los calores extremos observados en la última década habrían sido muy improbables sin la influencia del hombre en el sistema climático. van Vuuren, D.P. Elaborar e implementar dichas estrategias puede generar un impacto positivo en la marca de las empresas mediante la reducción de costos, mejores relaciones comerciales, beneficios ambientales y mejor manejo de recursos que les permitirá obtener mayores beneficios económicos (Cruzado-Ramos & Brioso, 2020). Barriers for transitioning from climate change mitigation and adaptation planning to practical policy implementation include finance, information, technology, public attitudes, social values and practices (Whitmarsh et al., 2011; Corner and Clarke, 2017)255, and human resource constraints. Disminución de las zonas habitables, resultando en el desplazamiento de poblaciones. Accordingly, warming from pre- industrial levels to the decade 2006–2015 is assessed to be 0.87°C (likely between 0.75°C and 0.99°C). 2020, Sustainability Performance Evaluation in Building Projects by Integrating Lean and Sustainable Management Using the Delphi Method. The key surface temperature attribution studies underlying this finding (Gillett et al., 2013; Jones et al., 2013; Ribes and Terray, 2013)91 used temperatures since the 19th century to constrain human-induced warming, and so their results are equally applicable to the attribution of causes of warming over longer periods. Regional warming for the 2006–2015 decade relative to 1850–1900 for the annual mean (top), the average of December, January, and February (bottom left) and for June, July, and August (bottom right).

A ‘scenario’ is an internally consistent, plausible, and integrated description of a possible future of the human–environment system, including a narrative with qualitative trends and quantitative projections (IPCC, 2000)140. In Press. De hecho, por primera vez desde que se tienen registros, las conclusiones de un reciente estudio publicado el pasado marzo han puesto en jaque las estimaciones de evolución climática al revelar que la capacidad de la selva más grande del mundo de absorber carbono de la atmósfera se ha reducido hasta tal punto que ya podría estar liberando más carbono del que almacena. But the number of direct temperature measurements decreases as we go back in time. Asimismo, se registraron mayores aumentos de temperatura sobre la tierra (1.59 °C) que sobre el océano (0.88 °C). Since the rate of human-induced warming is proportional to the rate of CO2 emissions (Matthews et al., 2009; Zickfeld et al., 2009)178 plus a term approximately proportional to the rate of increase in non-CO2 radiative forcing (Gregory and Forster, 2008; Allen et al., 2018179; Cross-Chapter Box 2 in this chapter), these time scales also provide an indication of minimum emission reduction rates required if a warming greater than 1.5°C is to be avoided (see Figure 1.5, Supplementary Material 1.SM.6 and FAQ 1.2). The years 1880–1900 are subject to strong but uncertain volcanic forcing, but in the HadCRUT4 dataset, average temperatures over 1850–1879, prior to the largest eruptions, are less than 0.01°C from the average for 1850–1900. Gomis, E. Lonnoy, T. Maycock, M. Tignor, and T. Waterfield (eds.)]. Recuperado de, Ministerio del Ambiente. The IPCC AR4 and Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation (SREX) reports were mostly based on simulations from the CMIP3 experiment, while the AR5 was mostly based on simulations from the CMIP5 experiment. ‘Risk’ refers to potential negative impacts of climate change where something of value is at stake, recognizing the diversity of values. The AR5 also introduced the notion of climate-resilient development pathways, with a more explicit focus on dynamic livelihoods, multi-dimensional poverty, structural inequalities, and equity among poor and non-poor people (Olsson et al., 2014)149. This report adopts the 51-year reference period, 1850–1900 inclusive, assessed as an approximation of pre-industrial levels in AR5 (Box TS.5, Figure 1 of Field et al., 2014)78. Climate change scenarios are used for analysing and contrasting climate policy choices. In: Bowerman, N.H.A. For CO2, which takes hundreds of thousands of years to be fully removed from the atmosphere by natural processes following its emission (Eby et al., 2009; Ciais et al., 2013)158, the multi-century warming commitment from emissions to date in addition to warming already observed is estimated to range from slightly negative (i.e., a slight cooling relative to present-day) to slightly positive (Matthews and Caldeira, 2008; Lowe et al., 2009; Gillett et al., 2011; Collins et al., 2013)159. Reducing emissions to zero corresponds to stabilizing cumulative CO2 emissions (Figure 1.4c, solid lines) and falling concentrations of CO2 in the atmosphere (panel c dashed lines) (Matthews and Caldeira, 2008; Solomon et al., 2009)116, which is required to stabilize GMST if non-CO2 climate forcings are constant and positive. El Perú está entre los 10 países más vulnerables del mundo al Cambio Climático. This report assesses the spectrum from global mitigation scenarios to local adaptation choices – complemented by a bottom-up assessment of individual mitigation and adaptation options, and their implementation (policies, finance, institutions, and governance, see Chapter 4). An important framing device for this report is the recognition that choices that determine emissions pathways, whether ambitious mitigation or ‘no policy’ scenarios, do not occur independently of these other changes and are, in fact, highly interdependent. Leach et al. There are many dimensions to this question, including the warming ‘commitment’ from past emissions of greenhouse gases and aerosol precursors. Significant governance challenges include the ability to incorporate multiple stakeholder perspectives in the decision-making process to reach meaningful and equitable decisions, interactions and coordination between different levels of government, and the capacity to raise financing and support for both technological and human resource development. The third is the asymmetry in capacity to shape solutions and response strategies, such that the worst-affected states, groups, and individuals are not always well represented (Robinson and Shine, 2018)32. Results are sensitive both to the confidence level chosen and the number of years used to estimate the current rate of anthropogenic warming (5 years used here, to capture the recent acceleration due to rising non-CO2 forcing). The projected impacts have diverse and uneven spatial, temporal, human, economic, and ecological system-level manifestations. Morice, C.P., J.J. Kennedy, N.A. Pathways in which warming exceeds 1.5°C before 2100, but might return to that level in some future century, are not considered 1.5°C pathways. A timeline of notable dates in preparing the IPCC Special Report on Global Warming of 1.5°C (blue) embedded within processes and milestones of the United Nations Framework Convention on Climate Change (UNFCCC; grey), including events that may be relevant for discussion of temperature limits. 3. Technologies for the active removal of other greenhouse gases, such as methane, are even less developed, and are briefly discussed in Chapter 4. Evita el consumo de alimentos que vienen envasados en plástico o en uno de sus derivados.

Frame, A. Otto, and M.R. Some pathways are more consistent than others with the requirements for sustainable development (see Chapter 5). El "efecto invernadero" es el calentamiento que se produce cuando ciertos gases de la atmósfera de la Tierra retienen el calor. Por otro lado, es muy probable que, a nivel mundial, las precipitaciones diarias extremas se intensifiquen en 7%  por cada grado centígrado adicional de calentamiento global aproximadamente.

The assessment of confidence involves at least two dimensions, one being the type, quality, amount or internal consistency of individual lines of evidence, and the second being the level of agreement between different lines of evidence. Es bastante impactante conocer a profundidad hasta qué punto la influencia humana ha podido dañar el ambiente.

The Anthropocene and the Challenge of a 1.5° C Warmer World. Pathways considered in this report, consistent with available literature on 1.5°C, primarily focus on the time scale up to 2100, recognising that the evolution of GMST after 2100 is also important. Similarly, a permanent 1 W m−2 increase in radiative forcing has a similar temperature impact as the cumulative emission of H/AGWPH tonnes of CO2, where AGWPH is the Absolute Global Warming Potential of CO2 (Shine et al., 2005; Myhre et al., 2013; Allen et al., 2018)193. This is at the core of the scenario framework for climate change research that aims to facilitate creating scenarios integrating emissions and development pathways dimensions (Ebi et al., 2014; van Vuuren et al., 2014)145. Sustainable Development Pathways describe national and global pathways where climate policy becomes part of a larger sustainability transformation (Shukla and Chaturvedi, 2013; Fleurbaey et al., 2014; van Vuuren et al., 2015)146. Likewise, volcanic activity depressed temperatures in 1986–2005, partly offset by the very strong El Niño event in 1998. SDG13 also acknowledges that the UNFCCC is the primary international, intergovernmental forum for negotiating the global response to climate change. et al., 2016: Re-conceptualizing the Anthropocene: A call for collaboration. The connection between transformative climate action and sustainable development illustrates a complex coupling of systems that have important spatial and time scale lag effects and implications for process and procedural equity, including intergenerational equity and for non-human species (Cross-Chapter Box 4 in this chapter, Chapter 5). Recent studies also identify compound events (e.g., droughts and heat waves), that is, when impacts are induced by the combination of several climate events (AghaKouchak et al., 2014; Leonard et al., 2014; Martius et al., 2016; Zscheischler and Seneviratne, 2017)219. Okereke, C., 2010: Climate justice and the international regime. {1.2.1, 1.2.2}, Past emissions alone are unlikely to raise global-mean temperature to 1.5°C above pre-industrial levels (medium confidence), but past emissions do commit to other changes, such as further sea level rise (high confidence).

En: Proc. ¿Cómo te cambia la vida la educación financiera? The pace and scale of mitigation and adaptation are assessed in the context of historical evidence to determine where unprecedented change is required (see Chapter 4). This report assesses current knowledge of the environmental, technical, economic, financial, socio-cultural, and institutional dimensions of a 1.5°C warmer world (meaning, unless otherwise specified, a world in which warming has been limited to 1.5°C relative to pre-industrial levels). This is assessed within a transition to climate-resilient development pathways and connection between the evolution towards 1.5°C, associated impacts, and emission pathways. Kosaka, Y. and S.P. (2015)73 and Haustein et al. Por lo tanto, las concentraciones de GEI y la temperatura han sido bastante estables. Parker, 2018: Causes of irregularities in trends of global mean surface temperature since the late 19th century. CMIP5 values are the mean of the RCP8.5 ensemble, with 5–95% ensemble range. The aim of the Paris Agreement under the UNFCCC to ‘pursue efforts to limit’ the rise in global temperatures to 1.5°C above pre-industrial levels raises ethical concerns that have long been central to climate debates (Fleurbaey et al., 2014; Kolstad et al., 2014)23. This could be because of spontaneous climate variability or the response of the climate to natural perturbations, such as volcanic eruptions and variations in the sun’s activity. Climate change scenarios have been used in IPCC assessments since the First Assessment Report (Leggett et al., 1992)124. This is the earliest period with near-global observations and is the reference period used as an approximation of pre-industrial temperatures in the IPCC Fifth Assessment Report. They have been criticised: as too many and too complex, needing more realistic targets, overly focused on 2030 at the expense of longer-term objectives, not embracing all aspects of sustainable development, and even contradicting each other (Horton, 2014; Death and Gabay, 2015; Biermann et al., 2017; Weber, 2017; Winkler and Satterthwaite, 2017)278. The final report of the SED6 concluded that ‘in some regions and vulnerable ecosystems, high risks are projected even for warming above 1.5°C’. Para más información visitar:, Recibe nuestras noticias en tu correo diariamente, Su navegador no soporta iframes. The main impact of statistical infilling is to increase estimated warming to date by about 0.1°C (Richardson et al., 201868 and Table 1.1). Section 1.5 provides assessment frameworks and emerging methodologies that integrate climate change mitigation and adaptation with sustainable development. Impacts can be direct, such as coral bleaching due to ocean warming, and indirect, such as reduced tourism due to coral bleaching. It has been argued (Otto et al., 2015; Xu and Ramanathan, 2017)110 that achieving very ambitious temperature goals will require such an adaptive approach to mitigation, but very few studies have been performed taking this approach (e.g., Jarvis et al., 2012)111. Overshoot pathways are characterized by the peak magnitude of the overshoot, which may have implications for impacts. Morita, T. et al., 2001: Greenhouse Gas Emission Mitigation Scenarios and Implications. In: Leichenko, R. and J.A. {1.2.1}, Warming greater than the global average has already been experienced in many regions and seasons, with higher average warming over land than over the ocean (high confidence). La educación sobre el planeta es fundamental para revertir y ponerle fin a este fenómeno que avanza sin piedad arrasando con todo lo que se cruza en su camino. Marcott, S.A., J.D. The responses chosen could act to synergistically enhance mitigation, adaptation and sustainable development, or they may result in trade-offs which positively impact some aspects and negatively impact others. Plattner, R. Knutti, and P. Friedlingstein, 2009: Irreversible climate change due to carbon dioxide emissions. The first concerns differential contributions to the problem: the observation that the benefits from industrialization have been unevenly distributed and those who benefited most historically also have contributed most to the current climate problem and so bear greater responsibility (Shue, 2013; McKinnon, 2015; Otto et al., 2017; Skeie et al., 2017)30. The notion of a ‘pathway’ can have multiple meanings in the climate literature. Stocker, 2013: Impact of delay in reducing carbon dioxide emissions. Tol, R.S.J., T.K. In: AghaKouchak, A., L. Cheng, O. Mazdiyasni, and A. Farahmand, 2014: Global warming and changes in risk of concurrent climate extremes: Insights from the 2014 California drought. In contrast, sustained constant emissions of a SLCF such as methane, would (after a few decades) be consistent with constant methane concentrations and hence very little additional methane-induced warming (Allen et al., 2018; Fuglestvedt et al., 2018)190. At a global warming of 1.5°C, some seasons will be substantially warmer than 1.5°C above pre-industrial (Seneviratne et al., 2016)206. Schleussner, C.-F., P. Pfleiderer, and E.M. Fischer, 2017: In the observational record half a degree matters. The global transformation that would be needed to limit warming to 1.5°C requires enabling conditions that reflect the links, synergies and trade-offs between mitigation, adaptation and sustainable development. Shindell, D.T., 2015: The social cost of atmospheric release. 4. Los escépticos sostienen que no es posible afirmar que existe un calentamiento gradual porque no se cuenta con suficientes registros (o no son confiables) de las temperaturas en décadas pasadas. The Anthropocene offers a structured understanding of the culmination of past and present human–environmental relations and provides an opportunity to better visualize the future to minimize pitfalls (Pattberg and Zelli, 2016; Delanty and Mota, 2017)19,  while acknowledging the differentiated responsibility and opportunity to limit global warming and invest in prospects for climate-resilient sustainable development (Harrington, 2016)20 (Chapter 5). The impacts of 1.5°C global warming will vary in both space and time (Ebi et al., 2016)207. Los niveles de gases de efecto invernadero (GEI) han aumentado y descendido durante la historia de la Tierra pero han sido bastante constantes durante los últimos miles de años. MacMartin, D.G., K.L. Implementation challenges of 1.5°C pathways are larger than for those that are consistent with limiting warming to well below 2°C, particularly concerning scale and speed of the transition and the distributional impacts on ecosystems and socio-economic actors. This report defines a ‘1.5°C pathway’ as a pathway of emissions and associated possible temperature responses in which the majority of approaches using presently available information assign a probability of approximately one-in-two to two-in-three to warming remaining below 1.5°C or, in the case of an overshoot pathway, to warming returning to 1.5°C by around 2100 or earlier. Haustein, K. et al., 2017: A real-time Global Warming Index. Este div altura necesaria para permitir el sticky sidebar, Todos los derechos reservados. In this report, warming is defined as the increase in the 30-year global average of combined air temperature over land and water temperature at the ocean surface. Tanaka, K. and B.C.

Pandey, T. Masui, and S. Nishioka, 2017: Methodologies for leapfrogging to low carbon and sustainable development in Asia. It also includes exploring the potential beneficial opportunities associated with climate change (for example, longer growing seasons or increased yields in some regions). Climate-resilient development pathways can be considered at different scales, including cities, rural areas, regions or at global level (Denton et al., 2014271; Chapter 5). Shine, K.P., R.P. Hall, J., G. Fu, and J. Lawry, 2007: Imprecise probabilities of climate change: Aggregation of fuzzy scenarios and model uncertainties. ¿Qué es la Huella de Carbono Perú?. Consta de medidas concretas orientadas a soportar las consecuencias del cambio climático aún sin generar. Entre las medidas que deberían ser tomadas para reducir el calentamiento global se encuentran: La gran mayoría de países del mundo han firmado varios acuerdos para tratar de frenar el calentamiento global. Como resultado, el clima cambia de manera diferente en diferentes áreas. Fue creado por el Programa de las Naciones Unidas para el Medio Ambiente y la Organización Meteorológica Mundial en 1988. The connection between the enabling conditions for limiting global warming to 1.5°C and the ambitions of the SDGs are complex across scale and multi-faceted (Chapter 5). Mientras intentamos entenderlo, la faz de la Tierra tal y como la conocemos, sus costas, bosques y montañas nevadas están en vilo. These include baseline scenarios that assume no climate policy; scenarios that assume some kind of continuation of current climate policy trends and plans, many of which are used to assess the implications of the nationally determined contributions (NDCs); and scenarios holding warming below 2°C above pre-industrial levels. If present-day emissions of all GHGs (short- and long-lived) and aerosols (including sulphate, nitrate and carbonaceous aerosols) are eliminated (Figure 1.5, yellow lines) GMST rises over the following decade, driven by the removal of negative aerosol radiative forcing. La diferencia entre las temperaturas globales medias y durante las edades de hielo tan solo es de 9 grados Fahrenheit y estas oscilaciones se produjeron lentamente, durante el trascurso de cientos de miles de años. Temperature rise to date has already resulted in profound alterations to human and natural systems, including increases in droughts, floods, and some other types of extreme weather; sea level rise; and biodiversity loss – these changes are causing unprecedented risks to vulnerable persons and populations (IPCC, 2012a, 2014a; Mysiak et al., 2016; Chapter 3 Sections 3.4.5–3.4.13)2, Chapter 3 Section 3.4). Moss, R.H. et al., 2010: The next generation of scenarios for climate change research and assessment. et al., 2007: Global Climate Projections. Consequently, total human-induced warming is proportional to cumulative CO2 emissions (solid line in c), and GMST stabilises when emissions reach zero. Variables were calculated using a simple climate–carbon cycle model (Millar et al., 2017a)172 with a simple representation of atmospheric chemistry (Smith et al., 2018)173. Este es uno de los tantos datos sorprendentes del último informe preliminar del IPCC[1]. The magnitude and sign of the ZEC depend on the mix of GHGs and aerosols considered. {1.2.3, 1.2.4, Cross-Chapter Boxes 1 and 2}, This report assesses projected impacts at a global average warming of 1.5°C and higher levels of warming. In the context of this report, regional impacts of global warming at 1.5°C and 2°C are assessed in Chapter 3. Exponiendo a todos a altas temperaturas , sobre todo a aquellas personas que realizan trabajos en el exterior durante varias horas, como el campo o la construcción. Igualmente, junto el Ministerio de Economía y Finanzas (MEF), y el apoyo de GIZ, están iniciando en enero de 2012 un programa de adaptación en la inversión pública, es decir, en el gasto que realizan los gobiernos locales.

Uno de esos documentos es el “Quinto Informe de Evaluación (AR5) del Grupo Intergubernamental de Expertos sobre el Cambio Climático (IPCC)” del año 2013 que señala al factor humano como la causa más probable del calentamiento global observado desde la mitad del siglo XX. These terms are normally only applied to findings associated with high or very high confidence. N° 011-2011-MINAM. Climate models and associated simulations. Sterner, E., D.J.A. Las erupciones volcánicas, por ejemplo, emiten partículas que enfrían temporalmente la superficie de la Tierra. This is particularly true for developing and island countries in the tropics and other vulnerable countries and areas. To stay below any desired temperature limit, mitigation measures and strategies would need to be adjusted as knowledge of the climate response is updated (Millar et al., 2017b; Emori et al., 2018)137. Over the decade 2006–2015, many regions have experienced higher than average levels of warming and some are already now 1.5°C or more warmer with respect to the pre-industrial period (Figure 1.3). The AR5 suggested that equity, sustainable development, and poverty eradication are best understood as mutually supportive and co-achievable within the context of climate action and are underpinned by various other international hard and soft law instruments (Denton et al., 2014; Fleurbaey et al., 2014; Klein et al., 2014; Olsson et al., 2014; Porter et al., 2014; Stavins et al., 2014)22. Overall, the three-pronged emphasis on sustainable development, resilience, and transformation provides Chapter 5 an opportunity to assess the conditions of simultaneously reducing societal vulnerabilities, addressing entrenched inequalities, and breaking the circle of poverty. No somos conscientes de la gravedad del asunto, pero cada vez estamos más expuestos a las consecuencias del calentamiento global. We recommend moving this block and the preceding CSS link to the HEAD of your HTML file. et al., 2012: NOAA’s merged land-ocean surface temperature analysis. This revised methane forcing estimate results in a smaller peak warming and a faster temperature decline than assessed in AR5 (Figure 1.5, yellow line). See Supplementary Material 1.SM for further details and versions using alternative datasets. Sustained net zero anthropogenic emissions of CO2 and declining net anthropogenic non-CO2 radiative forcing over a multi-decade period would halt anthropogenic global warming over that period, although it would not halt sea level rise or many other aspects of climate system adjustment. Peak warming following elimination of all emissions was assessed at a few tenths of a degree in AR5, and century-scale warming was assessed to change only slightly relative to the time emissions are reduced to zero (Collins et al., 2013)169. Mediante el Renami, las instituciones públicas y privadas pueden registrar sus iniciativas que cooperan a la reducción de emisiones de GEI (Minam, 2020a). A las consecuencias que generan estos gases lo llamamos calentamiento global, pero este fenómeno en realidad está provocando una serie de cambios en los patrones meteorológicos de la Tierra a largo plazo que varían según el lugar. At the present rate, global temperatures would reach 1.5°C around 2040. Leach, N.J. et al., 2018: Current level and rate of warming determine emissions budgets under ambitious mitigation.

Fuglestvedt et al. This is not the case when emissions are aggregated using GWP or GTP, with discrepancies particularly pronounced when SLCF emissions are falling. The 30-year timespan accounts for the effect of natural variability, which can cause global temperatures to fluctuate from one year to the next. Para suscribirse haga click aquí.

Desde casa, cada persona puede tomar acción cambiando el modo en que consume y promover una manera más circular del consumo. 10. {1.2.3, 1.5.2}, There is no single answer to the question of whether it is feasible to limit warming to 1.5°C and adapt to the consequences. As such, it can describe individual scenario components or sometimes be used interchangeably with the word ‘scenario’. Bindoff, N.L. von Stechow, C. et al., 2015: Integrating Global Climate Change Mitigation Goals with Other Sustainability Objectives: A Synthesis. How are Risks at 1.5°C and Higher Levels of Global Warming Assessed in this Chapter? The presence or absence of enabling conditions would affect the options that comprise feasibility pathways (Section 4.4), and can reduce trade-offs and amplify synergies between options. (2011)297 and sources given therein. De hecho, el Panel Intergubernamental de Cambio Climático (IPCC) es el espacio más relevante de investigación e información científica sobre este tema. GISTEMP (Hansen et al., 2010)64 uses interpolation to infer trends in poorly observed regions like the Arctic (although even this product is spatially incomplete in the early record), while NOAAGlobalTemp (Vose et al., 2012)65 and HadCRUT (Morice et al., 2012)66 are progressively closer to a simple average of available observations. This estimate has the advantage of traceability to the AR5, but more formal methods of quantifying externally driven warming (e.g., Bindoff et al., 2013; Jones et al., 2016; Haustein et al., 2017; Ribes et al., 2017)87, which typically give smaller ranges of uncertainty, may be adopted in the future. Second, many of the most important findings of this report are conditional because they refer to ambitious mitigation scenarios, potentially involving large-scale technological or societal transformation. The AR5 discussed ‘poverty’ in terms of its multidimensionality, referring to ‘material circumstances’ (e.g., needs, patterns of deprivation, or limited resources), as well as to economic conditions (e.g., standard of living, inequality, or economic position), and/or social relationships (e.g., social class, dependency, lack of basic security, exclusion, or lack of entitlement; Olsson et al., 2014)40. The IPCC AR5 acknowledged that ‘adaptation and mitigation have the potential to both contribute to and impede sustainable development, and sustainable development strategies and choices have the potential to both contribute to and impede climate change responses’ (Denton et al., 2014)240. Temperatures are anchored to 1°C above pre-industrial in 2017; emissions–temperature relationships are computed using a simple climate model (Myhre et al., 2013; Millar et al., 2017a; Jenkins et al., 2018)122 with a lower value of the Transient Climate Response (TCR) than used in the quantitative pathway assessments in Chapter 2 to illustrate qualitative differences between pathways: this figure is not intended to provide quantitative information. Impulsar el mercado del carbono. Progress towards limiting warming to 1.5°C requires a significant acceleration of this trend. Reisinger, A. et al., 2014: Australasia. Por ejemplo; ante el descongelamiento de los glaciares andinos, se pierde agua potable, la cual es fuente de vida; y ante el aumento de climas extremos, aumenta la desertificación y disminuye la producción de cultivos como el maíz, la papa y el arroz (Castillo, 2019). The grey literature category extends to empirical observations, interviews, and reports from government, industry, research institutes, conference proceedings and international or other organisations. (2016)61 show that the use of blended SAT/SST data and incomplete coverage together can give approximately 0.2°C less warming from the 19th century to the present relative to the use of complete global-average SAT (Stocker et al., 201362, Figure TFE8.1 and Figure 1.2). et al., 2014: Recent intensification of wind-driven circulation in the Pacific and the ongoing warming hiatus. Cross-Chapter Box 4: Figure 1 Climate action is number 13 of the UN Sustainable Development Goals, Figure 1.6. Scenarios and pathways are used to explore conditions enabling goal-oriented futures while recognizing the significance of ethical considerations, the principle of equity, and the societal transformation needed. The histogram shows the population living in regions experiencing different levels of warming (at 0.25°C increments). Climate mitigation–adaptation linkages, including synergies and trade-offs, are important when considering opportunities and threats for sustainable development. Part II: application to global near-surface temperature. All rights reserved, España alcanzó su máximo histórico con con 47,4 ºC y Europa con 48,8 ºC. Es por esto que es importante invertir en mejorar la capacidad de adaptación de las construcciones para que la vulnerabilidad no siga aumentando (Chalmers, 2014).

Pero, ¿qué es exactamente el calentamiento global y cómo impacta en nuestro planeta y nuestro día a día? These different dependencies affect the emissions reductions required of individual forcers to limit warming to 1.5°C or any other level. The current level and rate of human-induced warming determines both the time left before a temperature threshold is exceeded if warming continues (dashed blue line in Figure 1.5) and the time over which the warming rate must be reduced to avoid exceeding that threshold (approximately indicated by the dotted blue line in Figure 1.5). At the present rate, global temperatures would reach 1.5°C around 2040. Perú se pone a la vanguardia en la acción climática con su Registro Nacional de Medidas de Mitigación de gases de efecto invernadero. Impacts may also be triggered by combinations of factors, including ‘impact cascades’ (Cramer et al., 2014)218 through secondary consequences of changed systems. Any comparison between 1.5°C and higher levels of warming implies risk assessments and value judgements and cannot straightforwardly be reduced to a cost-benefit analysis (Kolstad et al., 2014)39. Radiative forcing (top) and global mean surface temperature change (bottom) for scenarios with different combinations of greenhouse gas and aerosol precursor emissions reduced to zero in 2020. Así, bajo un escenario pasivo los efectos del cambio climático podrían ser . This implies that an assessment of feasibility would go beyond a ‘yes’ or a ‘no’. For example, density and risk exposure, infrastructure vulnerability and resilience, governance, and institutional capacity all drive different impacts across a range of human settlement types (Dasgupta et al., 2014; Revi et al., 2014; Rosenzweig et al., 2018)227. How are Potential Impacts on Ecosystems Assessed at 1.5°C versus Higher Levels of Warming? Human-induced warming reached approximately 1°C (likely between 0.8°C and 1.2°C) above pre-industrial levels in 2017, increasing at 0.2°C (likely between 0.1°C and 0.3°C) per decade (high confidence). ¿Cuánto ha contribuido la humanidad al cambio climático? Human rights comprise internationally agreed norms that align with the Paris ambitions of poverty eradication, sustainable development, and the reduction of vulnerability (Caney, 2010; Fleurbaey et al., 2014; OHCHR, 2015)35. Si bien no todos los Gases de Efecto Invernadero (GEI) son contaminantes, sí es cierto decir que todos los GEI ocasionan el calentamiento global, la razón del Cambio Climático. It should be noted that while some radiation modification measures, such as cirrus cloud thinning (Kristjánsson et al., 2016)249, aim at enhancing outgoing long-wave radiation, SRM is used in this report to refer to all direct interventions on the planetary radiation budget. (2018)97. and Kirtman et al. In this report, warming is defined as the increase in the 30-year global average of combined temperature over land and at the ocean surface. Likewise, given that the level of warming is currently increasing at 0.3°C–0.7°C per 30 years (likely range quoted in Kirtman et al., 201356 and supported by Folland et al., 2018)57, the level of warming in 2017 was 0.15°C–0.35°C higher than average warming over the 30-year period 1988–2017. Sensitivity to changing drivers varies markedly across systems and regions., Intergovernmental Panel on Climate Change (2021b). This section frames the implementation options, enabling conditions (discussed further in Cross-Chapter Box 3 on feasibility in this chapter), capacities and types of knowledge and their availability (Blicharska et al., 2017)239 that can allow institutions, communities and societies to respond to the 1.5°C challenge in the context of sustainable development and the Sustainable Development Goals (SDGs). et al., 2015: 100% clean and renewable wind, water, and sunlight (WWS) all-sector energy roadmaps for the 50 United States. Sin duda alguna, las actividades desarrolladas por los humanos están ocasionando el cambio climático, y a su vez están logrando que los eventos climáticos extremos sean cada vez más frecuentes e intensos. At the 21st Conference of the Parties (COP21) in December 2015, 195 nations adopted the Paris Agreement2. In Chapter 2, scenarios of a 1.5°C warmer world and the associated pathways are assessed. In this section, you will find all of the documents available to download for Chapter 1. Summary: Climate change represents an urgent and potentially irreversible threat to human societies and the planet. Depending on mitigation decisions after 2030, they cumulatively track toward a warming of 3°-4°C above pre-industrial temperatures by 2100, with the potential for further warming thereafter (Rogelj et al., 2016a; UNFCCC, 2016)49. Feasibility can be assessed in different ways, and no single answer exists as to the question of whether it is feasible to limit warming to 1.5°C. Climate change risks can be managed through efforts to mitigate climate change forcers, adaptation of impacted systems, and remedial measures (Section 1.4.1). Differences in vulnerability and exposure arise from numerous non-climatic factors (IPCC, 2014a)6. Any choice of reference period used to approximate ‘pre-industrial’ conditions is a compromise between data coverage and representativeness of typical pre-industrial solar and volcanic forcing conditions. AR5 (IPCC, 2013b)235 and World Bank (2013)236 underscored the non-linearity of risks and impacts as temperature rises from 2°C to 4°C of warming, particularly in relation to water availability, heat extremes, bleaching of coral reefs, and more. This chapter frames the context, knowledge-base and assessment approaches used to understand the impacts of 1.5°C global warming above pre-industrial levels and related global greenhouse gas emission pathways, building on the IPCC Fifth Assessment Report (AR5), in the context of strengthening the global response to the threat of climate change, sustainable development and efforts to eradicate . The assessment provides the state of knowledge, including an assessment of confidence and uncertainty.

One such measure is solar radiation modification (SRM), also referred to as solar radiation management in the literature, which involves deliberate changes to the albedo of the Earth system, with the net effect of increasing the amount of solar radiation reflected from the Earth to reduce the peak temperature from climate change (The Royal Society, 2009; Smith and Rasch, 2013; Schäfer et al., 2015)248.

Mucha es la información que circula, sobre todo en las redes, acerca del calentamiento global y sus consecuencias devastadoras sobre el planeta. Colours indicate different 1.5°C pathways. Central to the assessment is the reporting of impacts at 1.5°C and 2°C, potential impacts avoided through limiting warming to 1.5°C, and, where possible, adaptation potential and limits to adaptive capacity. This means that warming in many regions has already exceeded 1.5°C above pre-industrial levels. Del artículo de julio de 2017 de la revista National Geographic"True Colors". No solo es necesario producir información sino hacerla accesible y poder transmitirla a las diferentes culturas y realidades que tenemos en el mundo bajo una mirada multidisciplinaria. The storyline of this report (Figure 1.6) includes a set of interconnected components. Pitman, R. Knutti, and R.L. 7.3 Mitigación: Es la reducción de Gases de Efecto Invernadero o, en su defecto, la Captura de Gases de Efecto Invernadero, como por ejemplo a través de los bosques. This observed pattern reflects an on-going transient warming: features such as enhanced warming over land may be less pronounced, but still present, in equilibrium (Collins et al., 2013)104. While many impacts scale with the change in GMST itself, some (such as those associated with ocean acidification) scale with the change in atmospheric CO2 concentration, indicated by the fraction of cumulative CO2 emissions remaining in the atmosphere (dotted lines in Figure 1.4c). Extreme events, such as floods, droughts, and heat waves, especially when they occur in series, can significantly erode poor people’s assets and further undermine their livelihoods in terms of labour productivity, housing, infrastructure and social networks (Olsson et al., 2014)45. In the longer term, Earth system feedbacks such as the release of carbon from melting permafrost may require net negative CO2 emissions to maintain stable temperatures (Lowe and Bernie, 2018)163. In: Riahi, K. et al., 2017: The Shared Socioeconomic Pathways and their energy, land use, and greenhouse gas emissions implications: An overview. This initial warming is followed by a gradual cooling driven by the decline in radiative forcing of short-lived greenhouse gases (Matthews and Zickfeld, 2012; Collins et al., 2013)168. Thus standard cost–benefit analyses become difficult to justify (IPCC, 2014a; Dietz et al., 2016)296 and are not used as an assessment tool in this report. et al., 2013: Technical Summary. Impacts at 1.5°C of warming also depend on the emission pathway to 1.5°C. La temperatura media global y las concentraciones de dióxido de carbono (uno de los principales gases de invernadero) han fluctuado en un ciclo de cientos de miles de años conforme ha ido variando la posición de la Tierra respecto del sol. In framing the objective of holding the increase in the global average temperature rise to well below 2°C above pre-industrial levels, and to pursue efforts to limit warming to 1.5°C, the Paris Agreement associates the principle of equity with the broader goals of poverty eradication and sustainable development, recognising that effective responses to climate change require a global collective effort that may be guided by the 2015 United Nations Sustainable Development Goals. In: Barnett, J. et al., 2014: A local coastal adaptation pathway. Incluso, las temperaturas registradas durante el 2011 y el 2020 no solo coinciden con las observaciones del penúltimo periodo cálido multisecular[3] —de hace aproximadamente 125 mil años—, sino que superan a las del último —de hace aproximadamente 6500 años—. Note that the emissions associated with these schematic temperature pathways may not correspond to feasible emission scenarios, but they do illustrate the fact that the timing of net zero emissions does not in itself determine peak warming: what matters is total cumulative emissions up to that time. Cambridge University Press, Cambridge, UK and New York, NY, USA, pp. Chapter 5 covers linkages between achieving the SDGs and a 1.5°C warmer world and turns toward identifying opportunities and challenges of transformation. Figure 1.4 illustrates categories of (a) 1.5°C pathways and associated (b) annual and (c) cumulative emissions of CO2. This means that the conditions for achieving the global transformation required for a 1.5°C world will be heterogeneous and vary according to the specific context. The section on strengthening the global response (1.4) frames responses, governance and implementation, and trade-offs and synergies between mitigation, adaptation, and the Sustainable Development Goals (SDGs) under transformation, transformation pathways, and transition. Este incremento de temperaturas podría alcanzar un aumento de 2’2 grados frente a los niveles preindustriales en 2040 y los 3'8 en 2100, según el análisis de un grupo de más de 80 científicos en el informe Cambio climático y medioambiental en la cuenca mediterránea, realizado por la red Mediterranean Experts on Climate and Environmental Change (MedECC). New evidence since AR5 suggests a larger methane forcing (Etminan et al., 2016)170 but no revision in the range of aerosol forcing (although this remains an active field of research, e.g., Myhre et al., 2017)171. Chapter 5 takes sustainable development, eradicating poverty and reducing inequalities as its focal point for the analysis of pathways to 1.5°C and discusses explicitly the linkages between achieving SDGs while eradicating poverty and reducing inequality. Shakun, P.U. A range of pathways, both sustainable and not, are explored in this report, including implementation strategies to understand the enabling conditions and challenges required for such a transformation. Governance capacity includes a wide range of activities and efforts needed by different actors to develop coordinated climate mitigation and adaptation strategies in the context of sustainable development, taking into account equity, justice and poverty eradication. Concerns regarding equity have frequently been central to debates around mitigation, adaptation and climate governance (Caney, 2005; Schroeder et al., 2012; Ajibade, 2016; Reckien et al., 2017; Shue, 2018)27. The AR5 noted that climate change-driven impacts often act as a threat multiplier in that the impacts of climate change compound other drivers of poverty (Olsson et al., 2014)43. Institutional capacity to deploy available knowledge and resources is also needed (Mimura et al., 2014)256. and K. Caldeira, 2008: Stabilizing climate requires near-zero emissions. {1.1, 1.4}, Ambitious mitigation actions are indispensable to limit warming to 1.5°C while achieving sustainable development and poverty eradication (high confidence). Esto, como resultado del incremento de gases de efectos invernadero que se caracterizan por retener el calor. Fourth, there is an asymmetry in future response capacity: some states, groups, and places are at risk of being left behind as the world progresses to a low-carbon economy (Fleurbaey et al., 2014; Shue, 2014; Humphreys, 2017)33. Equity and ethics are recognised as issues of importance in reducing vulnerability and eradicating poverty. Hansen, J., R. Ruedy, M. Sato, and K. Lo, 2010: Global surface temperature change. This report recognizes the potential for adverse impacts and focuses on finding the synergies between limiting warming, sustainable development, and eradicating poverty, thus highlighting pathways that do not constrain other goals, such as sustainable development and eradicating poverty. Given that global temperature is currently rising by 0.2°C (±0.1°C) per decade, human-induced warming reached 1°C above pre-industrial levels around 2017 and, if this pace of warming continues, would reach 1.5°C around 2040. Incorporating strong linkages across sectors, devolution of power and resources to sub-national and local governments with the support of national government, and facilitating partnerships among public, civic, private sectors and higher education institutions (Leal Filho et al., 2018)257 can help in the implementation of identified response options (Chapter 4).

Trucos para que la Navidad no acabe con tu salud financiera. Global warming is defined in this report as an increase in combined surface air and sea surface temperatures averaged over the globe and over a 30-year period. (2021c). Matthews, H.D. Para estudiar este escenario, científicos del Departamento de Geodinámica de la Universidad de Granada, del Instituto Andaluz de Ciencias de la Tierra (centro mixto del CSIC y la Universidad de Granada), del Instituto de Ciencias del Mar de Barcelona (ICM-CSIC) y del grupo EDANYA de la Universidad de Málaga analizaron la rotura y la dinámica de desplazamiento del antiguo deslizamiento Storfjorden LS-1, localizado al suroeste de las Islas Svalbard, entre 420 metros y 1900 metros de profundidad, con una longitud de 60 kilómetros, un volumen de 40 kilómetros cúbicos albergados en un área de 1300 kilómetros cuadrados. Attention is directed to exploring questions of adaptation and mitigation implementation, integration, and transformation in a highly interdependent world, with consideration of synergies and trade-offs. For example, the RCPs describe GHG concentration trajectories (van Vuuren et al., 2011)141 and the SSPs are a set of narratives of societal futures augmented by quantitative projections of socio-economic determinants such as population, GDP and urbanization (Kriegler et al., 2012; O’Neill et al., 2014)142.

Myhre, G. et al., 2017: Multi-model simulations of aerosol and ozone radiative forcing due to anthropogenic emission changes during the period 1990–2015. By comparing impacts at 1.5°C versus those at 2°C, this report discusses the ‘avoided impacts’ by maintaining global temperature increase at or below 1.5°C as compared to 2°C, noting that these also depend on the pathway taken to 1.5°C (see Section 1.2.3 and Cross-Chapter Box 8 in Chapter 3 on 1.5°C warmer worlds). Mitchell, D. et al., 2016: Realizing the impacts of a 1.5°C warmer world. Such differences become important in the context of a global temperature limit just half a degree above where we are now. {1.1, Cross-Chapter Box 1}. Birkmann, J., T. Welle, W. Solecki, S.

How are Changes in Climate and Weather at 1.5°C versus Higher Levels of Warming Assessed? This framing also emphasises the global interconnectivity of past, present and future human–environment relations, highlighting the need and opportunities for integrated responses to achieve the goals of the Paris Agreement. Based on the CMIP5 ensemble, RCP2.6, provides a better than two-in-three chance of staying below 2°C and a median warming of 1.6°C relative to 1850–1900 in 2100 (Collins et al., 2013)130. Thin blue lines show the modelled global mean surface air temperature (dashed) and blended surface air and sea surface temperature accounting for observational coverage (solid) from the CMIP5 historical ensemble average extended with RCP8.5 forcing (Cowtan et al., 2015; Richardson et al., 2018)75.
