  • Information about climate1 is used to make decisions every day. From farmers deciding which crops to plant next season to mayors in large cities deciding how to prepare for future heat waves, and from an insurance company assessing future flood risks to a national security planner assessing future conflict risks from the impacts of drought, users of climate information span a vast array of sectors in both the public and private spheres. Each of these communities has different needs for climate data, with different time horizons (see Box 1) and different tolerances for uncertainty...

  • Global warming is the rising average temperature of Earth's atmosphere and oceans since the late 19th century and its projected continuation. Since the early 20th century, Earth's average surface temperature has increased by about 0.8 °C, with about two thirds of the increase occurring since 1980. Warming of the climate system is unequivocal, and scientists are more than 90% certain that most of it is caused by increasing concentrations of greenhouse gases produced by human activities such as deforestation and the burning of fossil fuels.

  • 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....

  • Over the past several years, scientists, public health officials, and policy makers have become increasingly interested in understanding how the emergence and spread of infectious diseases could be affected by environmental factors, particularly variations in climate. In September 1995 the Institute of Medicine/ National Academy of Sciences and the National Science and Technology Council held a Conference on Human Health and Global Climate Change.

  • Water vapor is the dominant greenhouse gas, the most important gaseous source of infrared opacity in the atmosphere. As the concentrations of other greenhouse gases, particularly carbon dioxide, increase because of human activity, it is centrally important to predict howthewater vapor distribution will be affected. To the extent that water vapor concentrations increase in a warmer world, the climatic effects of the other greenhouse gases will be amplified.

  • 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.

  • The Earth’s polar regions (see Figure 1.1) are ecologically, economically, and, increasingly, geopolitically important; they are particularly vulnerable to the speed and magnitude of climate change and have significant potential to influence the global climate system (Oreskes, 2004; IPCC, 2007a; Anderegg et al., 2010). Climate models and observational data have shown that polar regions have warmed at substantially higher rates than the global mean (IPCC, 2007c).

  • The unprecedented prospect of human-induced (rapid) changes to the global climate has prompted a large international scientific effort to assess the evidence. The IPCC, established within the UN framework in 1988, was charged with advis- ing national governments on the causes and processes of climate change; likely impacts and their associated costs; and ways to lessen the impacts. The IPCC’s Third Assessment Report (2001) projects an increase in average world surface temperature ranging from 1.4 to 5.8°C over the course of the twenty-first century (see Figure 1.1).

  • Climate change and sea level rise are an existing threat of humanity in the 21st century. The victims of natural disasters and climate change are none other than people who suffer with increasing levels of disasters for a country and a region. Therefore, the study proposes and implements solutions to minimize negative impacts of natural disasters and adapts to the process of global climate change, which is an urgent task of every country.

  • 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.

  • Many indicators regarding the health of the world’s environment remain firmly in the red. Trends such as climate change, water scarcity, air pollution, biodiversity loss and ecosystem degradation all continue to threaten our finite stock of natural capital and the ability of our economy to provide sustainable growth and prosperity for all. A great deal of this environmental damage is caused by the way we do business. If we are to create a truly sustainable global economy, then we must change our economic models so that business can become part of the solution, not part of the problem. ...

  • The meteorological archive contains what is believed to be the longest continuous daily climate series from a single site in the UK and Ireland and one of the longest in the world. The climate station has been continuously maintained since 1795, with readings currently taken every day at 09:00 (GMT). Calibration of these data has enabled researchers and government agencies to use the Armagh series for reports and research into global warming. This is a subject of strategic importance for Northern Ireland as we move into an era of rapid climate change.

  • In this section, we aim to use a comparative analysis between the Arab Region and the rest of the world to assess the current state of the media industry and identify key opportunities for growth. We will assess the similarities between the media industry in the Arab Region and the global landscape, such as changing consumption trends, the evolution of new platforms and new monetisation models.

  • 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.
