  • Mô hình khí hậu khu vực (Regional Climate Model - RCM) ngày nay đã trở thành một công cụ quan trọng trong mô phỏng và dự báo khí hậu. Tuy nhiên công cụ dự báo khí hậu này cũng có nhiều khiếm khuyết. Do đó việc cải thiện kết quả dự báo của RCM góp phần nâng cao chất lượng dự báo khí hậu nói chung. Việc hạ quy mô (downscaling) từ mô hình toàn cầu có độ phân giải thô bằng mô hình khu vực có độ phân giải tinh cho ta dự báo chi tiết hơn.

  • ‘Climate models’ is a very broad topic, so a single volume can only offer a small sampling of relevant research activities. This volume of 14 chapters includes descriptions of a variety of modeling studies for a variety of geographic regions by an international roster of authors. The climate research community generally uses the rubric ‘climate models’ to refer to organized sets of computer instructions that produce simulations of climate evolution.

  • This is the first of two reports that address the complex issue of incorporating the needs of climate research into the National Polar-orbiting Operational Environmental Satellite System (NPOESS). NPOESS, which has been driven by the imperative of reliably providing short-term weather information, is itself a union of heretofore separate civilian and military programs. It is a marriage of convenience to eliminate needless duplication and reduce cost, one that appears to be working.

  • Evidence grows daily of the rapid changes in climate due to human activities and their impact on plants and animals. Plant function is inextricably linked to climate and atmospheric carbon dioxide concentration. On the shortest and smallest scales the climate affects the plant’s immediate environment and thus directly influences physiological processes. On longer and larger time and space scales climate influ- ences species distribution and community composition and determines what crops can be viably produced in managed agricultural, horticultural and forestry ecosys- tems.

  • This book provides an interdisciplinary view of how to prepare the ecological and socio-economic systems to the reality of climate change. Scientifically sound tools are needed to predict its effects on regional, rather than global, scales, as it is the level at which socio-economic plans are designed and natural ecosystem reacts. The first section of this book describes a series of methods and models to downscale the global predictions of climate change, estimate its effects on biophysical systems and monitor the changes as they occur....

  • This book offers an interdisciplinary view of the biophysical issues related to climate change. Climate change is a phenomenon by which the long-term averages of weather events (i.e. temperature, precipitation, wind speed, etc.) that define the climate of a region are not constant but change over time. There have been a series of past periods of climatic change, registered in historical or paleoecological records.

  • Several years ago the Open University in Heerlen and Maastricht University decided to launch a course on ‘Climate and the Environment’, with a diverse team of authors. Both natural and social scientists, from several regions of the world, contributed to this book. Initially, the book was intended as a textbook within this course for students of Environmental Sciences programmes at the Open University and Maastricht University. As the book developed it became clear that it would be an excellent source to anyone professionally engaged in the wide area of the enhance greenhouse effect....

  • Climate change is happening now. Climate-induced disasters are occurring in the Asia Pacific region, where a distinctly increasing trend has been observed in recent decades. This shows that the region is the most disaster prone, compared with other parts of the world. Studies on the causes of disaster in many affected regions suggest that in a typical disaster, cities with high population density see increases in mortality and number of people affected. Increased economic losses within the region are also inevitable.

  • The government is taking the lead by developing a management plan for the northeast region of Alberta. This plan will look beyond oil sands development on a project-by-project basis by addressing the cumulative effects of development. This approach enables responsible resource development that incorporates creative and innovative solutions to secure economic prosperity, while maintaining the province’s commitment to environmental protection and stewardship.

  • We are aiming to create new partnerships with the private sector to increase green investments. The aim is to demonstrate to major private sector investors that climate friendly investments are financially viable. In particular we are working on two partnerships with the private sector for climate-friendly funds. We and other public sector players will consider investing in these funds alongside private pension and sovereign wealth funds.

  • The United States and other industrialized countries have committed to financial assistance for environmental initiatives through several multilateral agreements (e.g., the Montreal Protocol (1987), the United Nations Framework Convention on Climate Change (1992), United Nations Convention to Combat Desertification (1994), and the Copenhagen Accord (2009)).

  • Greenhouse gases are accumulating in Earth’s atmosphere as a result of human activities, causing surface air temperatures and subsurface ocean temperatures to rise. Temperatures are, in fact, rising. The changes observed over the last several decades are likely mostly due to human activities, but we cannot rule out that some significant part of these changes is also a reflection of natural variability. Human-induced warming and associated sea level rises are expected to continue through the 21st century.

  • A major task of our time is to ensure adequate food supplies for the world’s current population (now nearing 7 billion) in a sustainable way while protecting the vital functions and biological diversity of the global environment. The task of providing for a growing population is likely to be even more difficult in view of actual and potential changes in climatic conditions due to global warming, and as the population continues to grow. Current projections suggest that the world’s temperatures will rise 1.8–4.

  • Climate change has been happening in scales of the global, regional as well as in Vietnam because of human activities which impulse greenhouse gas increasing in the atmosphere. To cope effectively with climate change, the understanding of future climate based on climate change scenarios, particularly scenarios for small areas, is essential. This paper concerns on the application of MAGICC/SCENGEN 5.3 software in combination with statistic correction to develop climate change scenarios for small areas in Vietnam. Results showed that the temperature is increased, while rainfall is changed...

  • Rice area of the Mekong Delta (MD) has decreased in recent years, especially the shift from rice land into land for industrial parks and saline land due to sea level rise and effects of climate change. In addition, the rate of population growth also requires increasingly high demand for rice in the region. By using the model, results showed that the population of the Mekong Delta will be at 26,956.5 thousand inhabitants,

  • The most significant issues facing mankind today are related to the quality of our environment. Past decisions did not always consider environmental factors as critical elements. However, current decisions made daily should reflect the importance of the environment. All environment-related issues are multidisciplinary, ranging from science and engineering to social, economic, and regulatory issues. Further, these issues are not related to any one region or country, but are global in nature, requiring multidisciplinary, multiorganizational, and multinational educational efforts....

  • Abstract. In this study, we assessed the impact of sea level rise, one of the most ascertained consequences of global climate change, for water levels in the Vietnamese Mekong Delta (VMD). We used a hydraulic model to compute water levels from August to November – when flooding is presently critical – under sea level rise scenarios of 20 cm (= 20) and 45

  • In smaller regions such as the Carpathian Basin (located in Eastern/Central Europe), 50 km horizontal resolution may still not be appropriate to describe the meso-scale processes (e.g., cloud formation and convective precipitation). For this purpose on a national level several RCMs have been adapted with finer resolution (25 and 10 km). Here, results from two of the adapted RCMs for Hungary are analyzed, namely, models PRECIS and RegCM. In this paper, first, data and models from PRUDENCE, PRECIS and RegCM are presented.
