    Aligning Sub-national Climate Actions for the new post-Paris Climate Regime

    The rise of sub-national actors in global climate governance underscores the need for clear alignment between these efforts and their national counterparts. As these sub-national climate actions are filling gaps in mitigation, adaptation, and financing, among other functions, a critical question is how these efforts complement or overlap with national climate pledges. This consideration is particularly important in the context of the Paris Agreement’s mandate for fiveyear review cycles, where national governments will be asked to demonstrate progress towards climate mitigation goals and increase their ambition. In this paper, we argue that alignment – both vertically between multiple jurisdictions and horizontally with external networks and actors – is critical to clarifying climate actions between multiple levels of actors and to maximizing mitigation potential. We use nine case studies to demonstrate the varying degrees and modes of vertical integration between subnational and national climate actors. We find that the case studies embody different styles of vertical alignment, and exhibit significant variation in the degree and direction of vertical alignment within each of these modes. We also find that many case studies rely on horizontally- aligned international networks and coalitions to fill gaps in financial resources or technical support. As a proof of concept, we demonstrate that an additional 1 gigaton carbon dioxide equivalent (CO2e) in 2020 can be achieved in these nine case studies through stronger alignment that makes it possible to scale sub-national climate actions to the national level. These findings suggest there may be a missed opportunity to realize greater mitigation potential by fostering stronger vertical alignment, and enhancing coordination between horizontal networks of climate action and national governments

    The intrinsic X-ray luminosity distribution of an optically-selected SDSS quasar population

    In active galactic nuclei, the relationship between UV and X-ray luminosity is well studied (often characterised by αox\alpha_\text{ox}) but often with heterogeneous samples. We have parametrized the intrinsic distribution of X-ray luminosity, LXL_\text{X}, for the optically-selected sample of SDSS quasars in the Stripe 82 and XXL fields across redshifts 0.5-3.5. We make use of the available XMM observations and a custom pipeline to produce Bayesian sensitivity curves that are used to derive the intrinsic X-ray distribution in a hierarchical Bayesian framework. We find that the X-ray luminosity distribution is well described by a Gaussian function in log10LX{\log_{10}}L_\text{X} space with a mean that is dependent on the monochromatic 2500A UV luminosity, L2500L_{2500}. We also observe some redshift dependence of the distribution. The mean of the LXL_\text{X} distribution increases with redshift while the width decreases. This weak but significant redshift dependence leads to L2500L_{2500}-LXL_\text{X} and L2500L_{2500}-αox\alpha_\text{ox} relations that evolve with redshift, and we produce a redshift- and L2500L_{2500}-dependent αox\alpha_\text{ox} equation. Neither black hole mass nor Eddington ratio appear to be potential drivers of the redshift evolution.Comment: 18 pages, 16 figures (including appendices). Accepted for publication in MNRA

    Her Voice: Engaging and Preparing Girls With Disabilities for Science, Technology, Engineering, and Math Careers

    Science, technology, engineering, and math (STEM) related fields comprise the top 30 occupations expected to grow the fastest by 2026. This increase in job opportunities, coupled with the evolution of technology, is creating higher demands for diversity in the labor market. Currently all students require innovative training and support from a young age to pursue STEM careers successfully. However, women and girls with disabilities face unique barriers along the STEM education pipeline. In this paper, we report the current and projected labor market trends in the United States. We then consider how this labor market information can be used by elementary educators to engage girls with disabilities in STEM-related learning effectively. Finally, through our analysis of labor market needs and the available assessment and intervention literature, we present a science-informed framework for intervention

    Current approaches used in epidemiologic studies to examine short-term multipollutant air pollution exposures

    Get PDF
    Air pollution epidemiology traditionally focuses on the relationship between individual air pollutants and health outcomes (e.g., mortality). To account for potential copollutant confounding, individual pollutant associations are often estimated by adjusting or controlling for other pollutants in the mixture. Recently, the need to characterize the relationship between health outcomes and the larger multipollutant mixture has been emphasized in an attempt to better protect public health and inform more sustainable air quality management decisions

    Identifying Critical Employability Skills for Employment Success of Autistic Individuals: A Content Analysis of Job Postings

    Get PDF
    This study aimed to examine the literature on the skill sets of autistic individuals and determine how these skills align with current and projected future labour market needs. Based on a literature review, researchers identified the following skill categories common to autistic individuals: visual skills, attention to detail and systemizing composite skills. Researchers then gathered aggregated data on occupations and industries from over 90 state and federal sources in the United States. Next, they collected data on the most in-demand jobs, their industries and relevant skills by analysing hundreds of millions of online job postings. The results indicate the most viable occupations aligned with each skill category. There is minimal available research using labour market data to generate special education goals and transition plans for autistic students. By providing educators and practitioners with critical information regarding viable employment pathways, all stakeholders can more effectively and equitably prepare autistic individuals for the 21st-century workforce

    Beyond national climate action : the impact of region, city, and business commitments on global greenhouse gas emissions

    Get PDF
    This article quantifies the net aggregate impact in 2030 of commitments by individual non-state and subnational actors (e.g. regions, cities and businesses, collectively referred to as ‘NSAs’) to reduce greenhouse gas (GHG) emissions. The analysis was conducted for NSAs operating within ten major emitting economies that together accounted for roughly two-thirds of global GHG emissions in 2016. Our assessment includes 79 regions (e.g. subnational states and provinces), approximately 6,000 cities, and nearly 1,600 companies with a net emissions coverage of 8.1 GtCO2e/year, or a quarter of the ten economies’ total GHG emissions in 2016. The analysis reflects a proposed methodology to aggregate commitments from different subnational (i.e. regional and city government) and non-state (i.e. business) actors, accounting for overlaps. If individual commitments by NSAs in the ten high-emitting economies studied are fully implemented and do not change the pace of action elsewhere, projected GHG emissions in 2030 for the ten economies would be 1.2–2.0 GtCO2e/year or 3.8%–5.5% lower compared to scenario projections for current national policies (31.6–36.8 GtCO2e/year). On a country level, we find that the full implementation of these individual commitments alone could result in the European Union and Japan overachieving their nationally determined contributions (NDCs), while India could further overachieve its unconditional NDC target. In the United States, where the national government has rolled back climate policies, NSAs could become a potential driving force for climate action. Key policy insights Full implementation of reported and quantifiable individual commitments by regions, cities and businesses (NSAs) in ten major economies could reduce emissions by 3.8%–5.5% in 2030 below current national policies scenario projections. National governments’ mitigation targets could be more ambitious if they would take NSA commitments into account. With full implementation of such action, the European Union and Japan would overachieve their NDC targets. For the United States such action could help meeting its original 2025 NDC target in spite of rollbacks in national climate policies. The full universe of NSA climate action expands far beyond the subset of commitments analysed in this study; NSAs could become a strong driving force for enhanced action towards the Paris climate goals.</p
