A mitad de camino entre el ensayo y el libro de divulgación científica, Nuestro reto climático ofrece al lector de forma amena y comprensible todas las claves del mayor desafío al que jamás se ha enfrentado la humanidad: un rápido calentamiento global que lleva nuestra firma y al que resultará difícil adaptarse si no cambiamos profundamente nuestro modelo de sociedad. Estamos obligados a actuar con urgencia, en la década actual, para lograr la descarbonización en 2050 y esquivar los peores escenarios que plantean las proyecciones climáticas dadas a conocer por el Sexto informe del IPCC, publicado en el 2022, cuyos datos y conclusiones principales también se encuentran recogidos en estas páginas.
¿Qué es el cambio climático? ¿Es un fenómeno provocado por los seres humanos? ¿De dónde proceden las emisiones de gases de efecto invernadero? Si el mundo se está calentando, ¿por qué se producen olas de frío o nevadas históricas? ¿Hay vuelta atrás para evitar una catástrofe climática? El cambio climático es una realidad incuestionable. El aumento de las temperaturas está causando consecuencias preocupantes en cada rincón del planeta, por lo que debemos actuar urgentemente. Con este libro entenderemos las bases del cambio climático a través de un viaje por tierra, mar, aire e incluso resbalando por el hielo. Comprenderemos los orígenes de esta crisis, por qué se dan fenómenos tan dispares como inundaciones o sequías y, sobre todo, descubriremos por qué un problema aparentemente sencillo es en realidad uno de los mayores retos a los que se enfrenta la humanidad hoy en día. EL MAÑANA DEPENDE DE LAS DECISIONES QUE SE TOMEN HOY.
The North American Mosaic has four overarching features. First, it is, to the extent feasible, based on comparable information on the status and trends of major indicators of the state of the environment in Canada,Mexico, and the United States. Second, the report confirms that these three countries together make up an incredibly complex, dynamic, and interconnected ecosystem in which humans play a dominant and decisive role. Third, the report raises important and sometimes disquieting questions concerning the sustainability of some current trends. Finally, the report is a reminder that our economic, social, and physical well-being are utterly dependent on the life-sustaining services provided by nature. This report emphasizes the importance of developing mutually compatible economic, social, and environmental goals and policies across the three-country region.
This book presents the research results of an interdisciplinary study on climate change policies by the Enforcing Environmental Policy (EEP) Network, a project supported by the Human Dimension Potential Programme. Contributions are from highly qualified economic and legal specialists based at research institutes across Europe. The book gives answers to several questions related to the implementation of the international rules on climate change, most notably the Kyoto Protocol. It analyses ways and means to facilitate and encourage compliance with the objectives of the Kyoto Protocol. It is addressed to policy-makers, academics, business-sector and stakeholders throughout and outside Europe. Due to its interdisciplinary approach, this work is a distinctive and unique product compared to the existing literature on the subject. The effective implementation of climate protection and clean air policy requires an understanding of the political, legal and economic structures and constraints facing policy makers - and this is exactly what this book offers.
Based on twenty case studies of universities worldwide, and on a survey administered to leaders in 101 universities, this open access book shows that, amidst the significant challenges caused by the COVID-19 pandemic, universities found ways to engage with schools to support them in sustaining educational opportunity. In doing so, they generated considerable innovation, which reinforced the integration of the research and outreach functions of the university. The evidence suggests that universities are indeed open systems, in interaction with their environment, able to discover changes that can influence them and to change in response to those changes. They are also able, in the success of their efforts to mitigate the educational impact of the pandemic, to create better futures, as the result of the innovations they can generate. This challenges the view of universities as "ivory towers" being isolated from the surrounding environment and detached from local problems. As they reached out to schools, universities not only generated clear and valuable innovations to sustain educational opportunity and to improve it, this process also contributed to transform internal university processes in ways that enhanced their own ability to deliver on the third mission of outreach
This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.
This Child-Friendly Schools (CFS) Manual was developed during three-and-a-half years of continuous work, involving the United Nations Children's Fund education staff and specialists from partner agencies working on quality education. It benefits from fieldwork in 155 countries and territories, evaluations carried out by the Regional Offices and desk reviews conducted by headquarters in New York. The manual is a part of a total resource package that includes an e-learning package for capacity-building in the use of CFS models and a collection of field case studies to illustrate the state of the art in child-friendly schools in a variety of settings.
Cities of Tomorrow is a critical history of planning in theory and practice in the twentieth century, as well as of the social and economic problems and opportunities that gave rise to it. Trenchant, perceptive, global in coverage, this book is an unrivalled account of its crucial subject. The third edition of Cities of Tomorrow is comprehensively revised to take account of abundant new literature published since its original appearance, and to view the 1990s in historical perspective. This is the definitive edition, reviewing the development of the modern planning movement over the entire span of the twentieth century.
