  • 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.

  • Plants are continuously affected by a variety of environmental factors. Whereas biotic environmental factors are other organisms such as symbionts, parasites, pathogens, herbivores, and competitors, abiotic factors include parameters and resources which determine plant growth like temperature, relative humidity, light, availability of water, mineral nutrients, and CO 2 , as well as wind, ionizing radiation, or pollutants (Schulze et al. 2002 ) . The effect each abiotic factor has on the plant depends on its quantity or intensity.

  • Worldwide attention to environmental issues combined with the energy crisis force us to reduce greenhouse emissions and increase the usage of renewable energy sources as a solution to providing an efficient environment. This book addresses the current issues of sustainable growth and applications in renewable energy sources. The fifteen chapters of the book have been divided into two sections to organize the information accessible to readers.

  • When planning how to reduce the threat of global warming and how to adapt to it, a very important piece of information is how intense the change will be. That implies estimating the trends of future concentrations of greenhouse gasses, and the potential future changes in temperature, precipitation, storm events and other climatic variables. These predictions are important not only to estimate the magnitude of the changes, but also to determine the uncertainty surrounding them.

  • Understanding greenhouse gas sources, emissions, measurements, and management is essential for capture, utilization, reduction, and storage of greenhouse gas, which plays a crucial role in issues such as global warming and climate change. Taking advantage of the authors' experience in greenhouse gases, this book discusses an overview of recently developed techniques, methods, and strategies: - A comprehensive source investigation of greenhouse gases that are emitted from hydrocarbon reservoirs, vehicle transportation, agricultural landscapes, farms, non-cattle confined buildings, and so on.

  • 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.

  • Liquid fuel consumption by medium- and heavy-duty vehicles (MHDVs) represents 26 percent of all U.S. liquid transportation fuels consumed and has increased more rapidly—in both absolute and percentage terms—than consumption by other sectors. In early recognition of these trends, which are forecast to continue until 2035 (DOE, EIA, 2009), the Energy Independence and Security Act of 2007 (EISA; Public Law 110-140, Dec. 19, 2007), Section 108, was passed, requiring the U.S. Department of Transportation (DOT), for the first time in history, to establish fuel economy standards for MHDVs.

  • By general consent Minnesota has enjoyed a superior reputation for climate, soil, and scenery beyond that of any other State in the Union, with, perhaps, a single exception. The real ground of this pre-eminence, especially in climate, has not been well understood, owing, probably, in part, to the slight acquaintance with the general features and characteristics of the State itself, and, in part, to that want of attention which the subject of climatology and its effects on the health of mankind has deserved.

  • Climate change is a very real and urgent global issue. Its consequences are being experienced every day. We read about it in newspapers, hear it debated in Parliament and our children learn about it in school. It’s a problem we all share, because every single country will be affected. Together, today, we must take action to adapt to it and stop it — or, at least, slow it down. your essential guide It’s now clear that the emission of man-made greenhouse gases is causing climate change. The rate of change began as significant, has become alarming and is simply unsustainable in the...

  • Scientists predict the earth is facing 40-to-60 years of climate change, even if emissions of carbon dioxide and other global warming gases stopped today. One inevitable consequence of the greenhouse gases already in the atmosphere will be an increase in the frequency and severity of natural disaster events. Global Warming, Natural Hazards, and Emergency Management documents the imperative need for communities to prepare for the coming effects of climate change and provides a series of in-depth, road-tested recommendations on how to reduce risks for communities and businesses.

  • With increasing energy demands, dwindling fossil energy resources, and environmental concerns associated with criteria pollutants and greenhouse gases, significant attention in the power generation community has been focused on increasing efficiency and reducing emissions. A highly efficient and low-emission concept is the fuel cell gas turbine (GT) hybrid. Hybrid systems are comprised of fuel cells integrated with a GT engine. A variety of potential configurations have been proposed and a number of cycles have been investigated.
