    The United Nations Framework Convention on Climate Change was established in 1992 to stabilize greenhouse gas concentrations in the atmosphere to prevent dangerous anthropogenic interference with the climate system. The nation states of the world have attempted to arrest climate change through a state-centric large scale multilateral treaty making process. Yet, over a period of more than twenty years, little has been achieved toward that objective. The making of international climate change governance required to arrest climate change is falling short. Greenhouse gases, which scientists consider to be the main culprit of climate change, are increasing rapidly making every subsequent year’s emissions concentration a new record. Climate scientists say global temperatures rising above 2 degrees Celsius could be extremely dangerous. The 1992 Convention, 1997 Kyoto Protocol, 2009 Copenhagen Accord and subsequent agreements have failed to translate the goal and achieve the threshold target as no serious and viable policies are forthcoming. Instead, the United Nations’ climate conferences have become a yearly chore for diplomats. The complexities of climate change governance arise not only from the nature and uncertainty of its impact, but also from its embedded relationships with social, cultural, political, economic, historical and institutional dimensions. Appropriate responses to address the challenges of climate change are difficult in the absence of potential solutions in sight. The pre-requisite for any effective policy responses is that the decision making process be democratic, transparent, and inclusive so that the ultimate addressees can ‘own’ the problem and contribute to solutions. A sizable literature focuses on the causes and reasons behind climate change and advocates radical actions to arrest it. Other research highlights economic implications, alternatives to fossil fuels, consumption and production, scientific uncertainty and challenges the perennial North-South politics in seeking to explain the lack of progress. There has been little research on why international climate change governance is making only incremental progress. This thesis takes as its starting point the paucity of attention to working out how and why progress has not been made, drawing on insights from climate change negotiations, major climate agreements and analyses of data on media communications on the issues of international climate change negotiations for policy making. The research recognizes the complexity of climate change and takes a comprehensive approach in considering why has there been little progress in the making of an effective international climate change governance to prevent climate change. The thesis takes three complementary approaches in addressing the central research question. The first develops from the concept of a democratic deficit and posits that the failure of progress can be attributed to a lack of the democratic processes in grappling with the issues. The second explores the state-centric framework of UNFCCC and posits that since the environmental issues are non-territorial, the challenges postulated by climate change cannot be resolved and progress made by solely relying on a state-centric approach. The third is to do with media communications and posits the role of the media in public education as central to develop the necessary public support for addressing the issues of climate change. The Kyoto Protocol and the Copenhagen Accord, and how they were achieved are central to this research as these are the two major climate change agreements achieved internationally so far. This research concludes that the approaches we have adopted so far have been inadequate because of the lack of involvement of the main stakeholders in decision making processes. The common but differentiated and historical responsibilities, pertinent principles in 1992, no longer reflect current economic growth and greenhouse gas emission patterns. There is a need to review our state-centric institutional framework toward a more inclusive, participatory, and deliberative accountability whereby the public and businesses can ‘own’ the problem. The role of the media is paramount in this because it is the media that passes information from the scientists, experts and policy makers to the public. The research concludes that the media has a key role to play and needs to be more critical in advancing measures to address the problems of climate change

    Deep Low-Frequency Radio Observations of the NOAO Bootes Field: I. Data Reduction and Catalog Construction

    Full text link
    In this article we present deep, high-resolution radio interferometric observations at 153 MHz to complement the extensively studied NOAO Bootes field. We provide a description of the observations, data reduction and source catalog construction. From our single pointing GMRT observation of ~12 hours we obtain a high-resolution (26" x 22") image of ~11.3 square degrees, fully covering the Bootes field region and beyond. The image has a central noise level of ~1.0 mJy/beam, which rises to 2.0-2.5 mJy/beam at the field edge, placing it amongst the deepest ~150 MHz surveys to date. The catalog of 598 extracted sources is estimated to be ~92 percent complete for >10 mJy sources, while the estimated contamination with false detections is <1 percent. The low RMS position uncertainty of 1.24" facilitates accurate matching against catalogs at optical, infrared and other wavelengths. Differential source counts are determined down to <~10 mJy. There is no evidence for flattening of the counts towards lower flux densities as observed in deep radio surveys at higher frequencies, suggesting that our catalog is dominated by the classical radio-loud AGN population that explains the counts at higher flux densities. Combination with available deep 1.4 GHz observations yields an accurate determination of spectral indices for 417 sources down to the lowest 153 MHz flux densities, of which 16 have ultra-steep spectra with spectral indices below -1.3. We confirm that flattening of the median spectral index towards low flux densities also occurs at this frequency. The detection fraction of the radio sources in NIR Ks-band is found to drop with radio spectral index, which is in agreement with the known correlation between spectral index and redshift for brighter radio sources.Comment: 14 pages, 7 figures.

    Global burden of 369 diseases and injuries in 204 countries and territories, 1990–2019: a systematic analysis for the Global Burden of Disease Study 2019

    Background: In an era of shifting global agendas and expanded emphasis on non-communicable diseases and injuries along with communicable diseases, sound evidence on trends by cause at the national level is essential. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) provides a systematic scientific assessment of published, publicly available, and contributed data on incidence, prevalence, and mortality for a mutually exclusive and collectively exhaustive list of diseases and injuries. Methods: GBD estimates incidence, prevalence, mortality, years of life lost (YLLs), years lived with disability (YLDs), and disability-adjusted life-years (DALYs) due to 369 diseases and injuries, for two sexes, and for 204 countries and territories. Input data were extracted from censuses, household surveys, civil registration and vital statistics, disease registries, health service use, air pollution monitors, satellite imaging, disease notifications, and other sources. Cause-specific death rates and cause fractions were calculated using the Cause of Death Ensemble model and spatiotemporal Gaussian process regression. Cause-specific deaths were adjusted to match the total all-cause deaths calculated as part of the GBD population, fertility, and mortality estimates. Deaths were multiplied by standard life expectancy at each age to calculate YLLs. A Bayesian meta-regression modelling tool, DisMod-MR 2.1, was used to ensure consistency between incidence, prevalence, remission, excess mortality, and cause-specific mortality for most causes. Prevalence estimates were multiplied by disability weights for mutually exclusive sequelae of diseases and injuries to calculate YLDs. We considered results in the context of the Socio-demographic Index (SDI), a composite indicator of income per capita, years of schooling, and fertility rate in females younger than 25 years. Uncertainty intervals (UIs) were generated for every metric using the 25th and 975th ordered 1000 draw values of the posterior distribution. Findings: Global health has steadily improved over the past 30 years as measured by age-standardised DALY rates. After taking into account population growth and ageing, the absolute number of DALYs has remained stable. Since 2010, the pace of decline in global age-standardised DALY rates has accelerated in age groups younger than 50 years compared with the 1990–2010 time period, with the greatest annualised rate of decline occurring in the 0–9-year age group. Six infectious diseases were among the top ten causes of DALYs in children younger than 10 years in 2019: lower respiratory infections (ranked second), diarrhoeal diseases (third), malaria (fifth), meningitis (sixth), whooping cough (ninth), and sexually transmitted infections (which, in this age group, is fully accounted for by congenital syphilis; ranked tenth). In adolescents aged 10–24 years, three injury causes were among the top causes of DALYs: road injuries (ranked first), self-harm (third), and interpersonal violence (fifth). Five of the causes that were in the top ten for ages 10–24 years were also in the top ten in the 25–49-year age group: road injuries (ranked first), HIV/AIDS (second), low back pain (fourth), headache disorders (fifth), and depressive disorders (sixth). In 2019, ischaemic heart disease and stroke were the top-ranked causes of DALYs in both the 50–74-year and 75-years-and-older age groups. Since 1990, there has been a marked shift towards a greater proportion of burden due to YLDs from non-communicable diseases and injuries. In 2019, there were 11 countries where non-communicable disease and injury YLDs constituted more than half of all disease burden. Decreases in age-standardised DALY rates have accelerated over the past decade in countries at the lower end of the SDI range, while improvements have started to stagnate or even reverse in countries with higher SDI. Interpretation: As disability becomes an increasingly large component of disease burden and a larger component of health expenditure, greater research and developm nt investment is needed to identify new, more effective intervention strategies. With a rapidly ageing global population, the demands on health services to deal with disabling outcomes, which increase with age, will require policy makers to anticipate these changes. The mix of universal and more geographically specific influences on health reinforces the need for regular reporting on population health in detail and by underlying cause to help decision makers to identify success stories of disease control to emulate, as well as opportunities to improve.
