  • 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....

  • The world’s climate is changing, and it will continue to change throughout the 21st century and beyond. Rising temperatures, new precipitation patterns, and other changes are already affecting many aspects of human society and the natural world. Climate change is transforming ecosystems at extraordinary rates and scales.

  • 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.

  • Climate change is a long-term shift in the statistics of the weather (including its averages). For example, it could show up as a change in climate normalcy (expected average values for temperature and precipitation) for a given place and time of year, from one decade to the next. We know that the global climate is currently changing. The last decade of the 20th Century and the beginning of the 21st have been the warmest periods in the entire global instrumental temperature record, starting in the mid-19th century.

  • Twenty years ago, world leaders gathered at the Earth Summit in Rio de Janeiro and signed the first global agreement to tackle climate change. At the time, the impacts of climate change on communities and economies were just beginning to be understood, and the role of the private sector in responding to these challenges was only just emerging. But two decades later, climate change is no longer a distant threat looming on the horizon; it has emerged as arguably the greatest global challenge of our time.

  • Anomalous climatic outcomes such as higher temperatures, intense rainfall and flood, frequent and severe droughts are now at the new level. Without appropriate adaptation measures, climate change is bound to exacerbate vulnerability of society, place food security and human health at risk, threaten the lives of growing urban population and impede the goal of attaining sustainable development. The human and social dimensions of climate change, including climate policy, are essential parts of our response to the many challenges emanating from climate change....

  • In the framework of the program "Asian Cities Climate Change Resilience Network" funded by Rockefeller Foundation, Vietnam Institute of Hydrology, Meteorology and Environment carried out this study with the aim to strongly support the development of action plan to respond to climate change for Quy Nhon city. The study developed climate change (temperature and rainfall) and sea level rise scenarios corresponding to some key emission scenarios, namely A1FI, A2 and B2. Impacts of climate change on main sectors such as water resources, agriculture and tourism were also assessed.

  • This study investigates impacts of climate change on water resource in the Huong River basin in the Central Vietnam. Hydrological responses of six climate change scenarios were calculated. Results reveal that climate change would cause significant increase in rainfall in wet season resulting in an increase in river flow. By contrast, the decreasing trend of river flow in dry season is a consequence of the decline of rainfall and increase of evapotranspiration under most scenarios. Sea level rise coupled with the lowering of river stages may exacerbate salinity intrusion.

  • Rapid socio–economic development leads to a great increase in water demand of many sectors and conflicts between water users. Moreover, studies have warned about serious degree of influence of climate change (CC) on Vietnam, particularly on the water resources. Therefore, assess CC impacts on water balances are very necessary task. The Ministry of Natural Resources and Environment has completed the appropriate climate change scenarios in Vietnam [1].

  • Climate change (CC) is one of the most significant challenges facing human beings in the 21st century. CC will seriously affect lives, production and environment worldwide. It also leads to the increasing temperature and one of its consequences is sea level rise, resulting in unpredicted changes of the river flow. This may cause more severe floods, serious drought and water shortage, further to continent of the salinity intrusions and negatively effect on the human’s lives, socio-economic development.

  • The Earth is the only planet in our solar system that supports life. The complex process of evolution occurred on Earth only because of some unique environmental conditions that were present: water, an oxygen-rich atmosphere, and a suitable surface temperature. Climate change refers to a statistically significant variation in either the mean state of the climate or in its variability, persisting for an extended period (typically decades or longer).

  • 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...

  • This book contains a set of papers presented during the world’s second online climate change conference (Climate 2009) held on 2–6 Nov 2009. The idea of running on-line climate conferences was born in Hamburg in the summer of 2008. With the first on-line climate change conference (titled “Climate 2008”) and the second one titled “Climate 2009” groundbreaking a methodology was established: the execution of climate change conferences which are not – paradoxically – harmful to the climate as conventional conferences are, but ones which are climate-neutral....
