  • 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.

  • The essential oil industry is under threat from numerous issues at present. Rising agricultural input costs, particularly petrochemical based fertilizers and fuels are squeezing farmers’ profit margins. Rising food prices and the increasing value of housing and industrial land prices is creating competition for land, particularly around populated areas. Adverse weather conditions and changing climate are creating both short and long term problems. Poor crop yields are occurring much more regularly than before because of unusually heavy rain, hail, floods, heat-waves and cold snaps....

  • The heat radiation from gas flaring greatly affects the surrounding environment and particular crops planted within the vicinity of gas flare stations (Abdulkareem and Odigure, 2002). It also has a devastating effect on microorganisms and aquatic life. Heat radiation from gas flaring also causes an increase in heat waves hence there is the possibility that habitants of Niger-Delta Area, where the gas flaring stations are located will suffer heart stroke, heart attacks and other ailments aggravated by the heat (Odigure et al., 2003).

  • Physics has an important role in our life. Without physics and the work of physicists, our modern life would not exist. Using physics, people created machines, instruments and some different divices from the crudest to the most modern aspect. Techology is developed more rapidly, more modern day by day. Moreover, all other natural sciences- example chemistry, biology, medicinedepend upon physics for the foundations of their knowledge.

  • Almost all motorized transportation today involves the combustion of fossil fuels, which produces energy to be transformed into motion. This combustion is the reaction of the hydrogen and carbon present in the fuels with oxygen in the air to produce–in the ideal world–water vapour (H2O) and carbon dioxide (CO2). Neither of these products is damaging to human health.

  • Developed countries in lower latitudes will be more vulnerable - for example, water availability and crop yields in southern Europe are expected to decline by 20% with a 2°C increase in global temperatures. Regions where water is already scarce will face serious difficulties and growing costs. The increased costs of damage from extreme weather (storms, hurricanes, typhoons, floods, droughts, and heat waves) counteract some early benefits of climate change and will increase rapidly at higher temperatures.

  • Literature concerning the 1995 Chicago heat wave (Semenza et al. 1995) demonstrates the devastating toll physical stress took on the elderly living alone and forgotten in sweltering apartments who were afraid to open their windows, and were too poor to have fans or obtain the needed food and water for survival. Some public health department and other government agencies are working together to go door-to-door to find these hidden residents, help them prepare, and to be able to reach them if needed during a disaster.

  • As concerns P, the most common approach is to simply use total population levels. However, as MacKellar et al. (1995) and others have pointed out, it is not a priori clear that only the individual, rather than, say, households or communities, is the relevant demographic unit. To this one can add that a whole range of other demographic factors beyond simple population levels might also impact on emissions.

  • Heat shock genes respond to moderate heat stress by a wave of transcrip-tion. The induction phase is accompanied by the massive eviction of histones, which later reassemble with DNA during the ensuing phase of transcription downregulation. In this article, we identify determinants of this reassembly throughout the heat shock protein 104 gene (HSP104) tran-scription unit.

  • The global population of persons aged 60 and over is rising dramatically – especially in regions that experience the greatest risks of natural or conflict-related emergencies. Headlines of the plight of older persons during the European heat wave of 2003 and Hurricane Katrina in the USA in 2005 shocked the world. In developing countries, their situation is generally much less widely-known and their needs and contributions have been largely invisible. But this is changing.

  • ON that summer day the sky over New York was unflecked by clouds, and the air hung motionless, the waves of heat undisturbed. The city was a vast oven where even the sounds of the coiling traffic in its streets seemed heavy and weary under the press of heat that poured down from above. In Washington Square, the urchins of the neighborhood splashed in the fountain, and the usual midday assortment of mothers, tramps and out-of-works lounged listlessly on the hot park benches. As a bowl, the Square was filled by the torrid sun, and the trees and grass drooped...

  • Talk of heat—or better not—on Xecho. This water-logged world combined all the most unattractive features of a steam bath and one could only dream of coolness, greenness—more land than a stingy string of islands. The young man on the promontory above the crash of the waves wore the winged cap of a spaceman with the insignia of a cargo-master and not much else, save a pair of very short shorts. He wiped one hand absently across his bare chest and brought it away damp as he studied, through protective sun goggles, the treacherous promise of the bright sea.

  • On the morning of June 15th, Guy Burckhardt woke up screaming out of a dream. It was more real than any dream he had ever had in his life. He could still hear and feel the sharp, ripping-metal explosion, the violent heave that had tossed him furiously out of bed, the searing wave of heat. He sat up convulsively and stared, not believing what he saw, at the quiet room and the bright sunlight coming in the window. He croaked, "Mary
