  • 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 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.

  • SWAT model was used to assess the impacts of climate change on the streamflow of Ben Hai River Basin. The daily streamflow for 1979 - 1996 and 1997 - 2006 was used to calibrate and validate the SWAT model, respectively. Nash efficiency values for the daily comparison were 0.72 for the calibration period and 0.74 for the validation period. Three scenarios were analyzed relative to the baseli ne with 28-year time series. A doubling of the atmospheric C02 content to 660 ppm (while holding other climatic variables) resulted in a 7.

  • The previous edition of Energy Technology Perspectives(ETP), published in summer 2008, called for an energy technology revolution to tackle the undesirable consequences of our current patterns of energy supply and use. It also highlighted that, if we did not alter course, concerns about energy security and the threat of dangerous climate change would only become much worse. So what – if any – progress have we made over the last two years in meeting these challenges? At first sight, it may seem as though not much has changed.

  • As a country which contains significant concentrations of population in fragile mountain eco- systems, expanding arid zones, various regions which are subject to periodic flooding, increasing deforestation and environmental degradation and high levels of poverty, Bolivia is particularly vulnerable to climate change. Its damaging impact can be seen in a range of phenomena such as increasingly severe and frequent flooding and landslides and the accelerated melting of tropical glaciers.

  • Natural resource managers and conservationists are coming to grips with the fact that rapid global warming and associated climate changes are already having a considerable impact on the world’s ecological systems. More and larger shifts are expected, even in the best-case scenarios for greenhouse gas emissions reductions and future warming. These climate changes are ushering in a fundamental shift in natural resource management and conservation, to help natural systems withstand and adapt to new climate conditions.

  • Most formal modelling in the past has used as a starting point a scenario of 2-3°C warming. In this temperature range, the cost of climate change could be equivalent to a permanent loss of around 0-3% in global world output compared with what could have been achieved in a world without climate change. Developing countries will suffer even higher costs. However, those earlier models were too optimistic about warming: more recent evidence indicates that temperature changes resulting from BAU trends in emissions may exceed 2-3°C by the end of this century.

  • Changing climate and rainfall patterns are expected to have significant impacts on agricultural productivity, especially in arid and semi‐arid regions that are already marginal for agriculture. Most climate modeling scenarios indicate that the dry lands of West and Central Asia and North Africa, for instance, will be severely affected by droughts and high temperatures in the years to come. This could lead to land degradation and agricultural expansion.

  • In all three cities, there is likely to be an increase in the number of persons exposed to flooding in 2050 under different climate scenarios compared to a situa- tion without climate change. For instance, in Bangkok in 2050, the number of persons affected (flooded for more than 30 days) by a 1-in-30-year event will rise sharply for both the low and high emission sce- narios—by 47 percent and 75 percent respectively— compared to those affected by floods in a situation without climate change.

  • The answer to this question is partly a matter of perspective. Current scientific evidence suggests that to mitigate the risk of dangerous climate change, global GHG emissions must be reduced by 60 to 80 percent by mid-century, 14 equivalent to many billions of tons of annual reductions. In this context, the contribution of the voluntary carbon offset market – even under the most optimistic demand scenarios – is likely to be small.

  • Climate change may initially have small positive effects for a few developed countries, but is likely to be very damaging for the much higher temperature increases expected by mid- to late-century under BAU scenarios. In higher latitude regions, such as Canada, Russia and Scandinavia, climate change may lead to net benefits for temperature increases of 2 or 3°C, through higher agricultural yields, lower winter mortality, lower heating requirements, and a possible boost to tourism.

  • Divided into four groups, the participants were asked to create scenarios of what could happen to the country once a Black government took over. Not what they wanted to or feared would happen. But what could. The participants though had one thing in common. They were deeply disaffected by the stalemate and wanted change.

  • Any study forecasting conditions four decades hence will be faced with large uncertainties and these need to be borne in mind in interpreting the results of this study. One uncertainty concerns the pathway of GHG emissions. To address that issue, the city case studies examined both a high and a low GHG emissions scenario to bracket the likely future conditions. In the climate change downscaling methodologies, there are uncertain- ties in forecasting the increase in extreme and seasonal precipitation under the different sce- narios.
