Wind Power

Electricity generated by wind power relies on air moving past a propeller to spin a turbine. Wind is created as a result of the differential heating of the earth's surface of the sun. Air masses move from areas of high atmospheric pressure to low atmosphere pressure. Wind energy creates very few greenhouse gases and will exist as long as the sun shines and winds blow. There are challenges to implementing wind energy, though. Wind energy, like other forms of renewable energy, operates...

United Nations

GLOBAL CLIMATE CHANGE is one of the most pressing issues of the 21st century. Because of the use of coal, oil, and gas for energy and the loss and degradation of forests, our planet is warming faster than at any time in the last several thousand years. We have already experienced warming temperatures, changing rainfall patterns, and sea-level rise. These disruptive forces have severe effects on economies, environment, and society of humankind. Nonetheless, the climate challenge may at the same...

Widely Disputed

The climate of the Cretaceous is less certain and more widely disputed. Average temperatures were higher than today by about 18 degrees F (10 degrees C). In fact, by the middle Cretaceous, equatorial ocean waters may have been too warm for sea life, and land areas near the equator may have been deserts, despite their proximity to water. The circulation of oxygen to the deep ocean may also have been disrupted. Large volumes of organic matter accumulated because they were unable to decompose and...

Pollution Water

WATER POLLUTION USUALLY describes the introduction or presence of harmful or objectionable substance in water in magnitude sufficient to alter the quality indices of natural water. It also connotes the presence of polluting substances in rivers, lakes, bays, seas, streams, underground water, or oceans in levels capable of resulting in measurable degradation of the water quality or usefulness. For example, if water contains too much contamination as a result of certain harmful chemical compounds...

Conclusion

The pollution of water resources can have serious and wide-ranging effects on the environment and human health. The immediate effects of water pollution can be seen in water bodies and the animal and plant life that inhabits them. Pollution poisons and deforms fish and other animals, unbalances ecosystems, and causes a reduction in biodiversity. Ultimately, these effects take their toll on human life. Drinking-water sources become contaminated, causing sickness and disease. Pollutants...

Climatic Data Tree Ring Records

PAST CLIMATES CAN be reconstructed by the use of the relationship between the climate and tree-growth parameters (dendroclimatology). Dendroclimatol-ogy is a sub-discipline of dendrochronology, which is the analysis of tree rings, including the dating of annual rings and study of patterns of ring characteristics, such as width, density, and isotopic composition. Annual growth rings of trees are natural recorders of climatic conditions (a proxy variable). Outside the tropics, in the temperate...

Legal Regulation

In a neoclassical utilitarian framework, the regulator is typically a natural or legal person or an entity with the power to regulate within its domain. The difficulty in the context of global issues such as planetary warming and climate change is the absence of a single regulator with the jurisdiction for the global atmosphere or the climate and hence no one with authority to regulate the global commons. Since local climate is not independent or separable from global atmosphere and does not...

Agulhas Current

The agulhas current is the major western boundary current of the Southern Hemisphere. It completes the anti-cyclonic gyre of the South Indian Ocean, and because the African continent terminates at a relatively modest latitude, it becomes a mechanism for the climatologically important inter-ocean exchange between the Indian and Atlantic Oceans. The south-westward flowing Agulhas Current only becomes fully constituted along the east coast of southern Africa at a latitude somewhere between Durban...

Climate Change As A Merchandise

Programs about the environment and related issues have become merchandise that can be bought and sold by producers to distributors and television networks. As with any other program, the value of a one-hour feature on climate change will depend, among other factors, on the audience it gathered when it was first aired. Other elements are the year it was produced, the cost of its rental, and its original language (if a translation is needed). Some television programs are sold on videocassette or...

Thermohaline Circulation

THERMOHALINE CIRCULATION IS global oceanic circulation generated by buoyancy fluxes resulting from heat and freshwater exchange between the ocean, atmosphere, cryosphere, and land. External forcing leading to an increase in water density (i.e., cooling or salinity rise) causes the sinking of more dense water (so-called thermohaline convection) and compensating transport of more light shallower waters of the upper mixed layer and thermocline. This process forms thermohaline overturning, which is...

Forced Climate Variability

STUDIES ON GLOBAL warming and climate change generally distinguish between internally generated and externally-forced climate variability. Internally generated variability is the result of processes within a system, while externally-forced variability is caused by some factors outside the system. A classic example of externally-forced climate variability is represented by the changes caused by variations in the amount and distribution of solar energy incidents on the Earth because of the...

Budyko Mikhail 19202001

MIKHAIL IVANOVICH BUDYKO was an environmental scientist who was internationally recognized for his pioneering work on the Earth's energy balance, surface hydrology, and climate change, and the role of climate in regulating Earth's biosphere. His work brought about the scientific discipline termed physical climatology, which, in contrast to empirical climatology, is based on the first principles quantitative analysis. Budyko strongly emphasized the importance of the Earth's surface and...

Beyond Polar Bears And Penguins

Simplified presentations on polar bears and penguins that do not account for spatial and temporal processes can never engage the types of ecosystem complexities that these two ecosystem examples reveal. In other words, the iconification of globalization through images of single species precludes a deeper understanding of global warming from an ecological perspective. Moreover, the focus on specific species of animals deemed more worthy of protecting and saving from extinction reflects the...

Thunderstorms

A THUNDERSTORM IS a localized storm that is produced by a cumulonimbus cloud and always contains thunder and lightning. Thunderstorms form in conditionally unstable environments, meaning there is cold, dry air aloft over warm, moist surface air. This causes the air to become buoyant and allows for rising air motion. A lifting mechanism is also needed to start the air moving. Such lifting mechanisms include surface heating, surface convergence, lifting caused by mountains, or lifting along...

Foundation for International Environmental Law and Development

THE foundation for International Environmental Law and Development (FIELD) was established in London in 1989 by a small group of international lawyers interested in the protection of the environ ment and the promotion of sustainable development. The organization provides advice and assistance to governments, inter-governmental and non-governmental groups worldwide. FIELD works for the development of international legislation that defends the environment and encourages fair and sustainable...

Boundary conditions

Some consider changes in solar radiation pattern and timing associated with Milankovitch cycles an important factor in maintaining a glacial climate. These changes are routinely included in GCM simulations of the LGM, however, they have minimal impact, as they were actually very similar to today. The continental configuration was also very similar to today, and changes need not be considered. The conditions at the LGM were the culmination of 100,000 years of cooling, thus models of the LGM must...

Winds Easterlies

This explains why prevailing winds in the mid-latitude northern hemisphere come from the west. An understanding of wind generation helps to explain the operation of ocean currents. There are two general types of ocean circulation and both result from solar heating (1) WDC, and (2) thermohaline circulation (THC). Differential solar heating generates wind. Wind blowing across the surface of the ocean causes the water to move. The direction of the ocean current is determined in part by...

The university's endowment is currently valued at about...

Villach Conference

The conference held in Villach, Austria, from October 9 to 15, 1985, was the result of the continuing work of several international entities. In some views, the background to the conference and the starting point for internationally cohesive attempts to understand the issues related to the stratospheric ozone layer depletion and climate change have been traced to the UN Conference on Human Development in Stockholm in 1972. The technical, scientific understanding of the possibility of...

Antigua and Barbuda

Congo

THE REpuBLIC OF the Congo, a former French colony, has a land area of 132,047 sq. mi. (342,000 sq. km.), with a population of 3,999,000 (2006 est.), and a population density of 31 people per sq. mi. (12 people per sq. km.). Forests cover 62 percent of the country, with less than one percent of arable land, and 29 percent used for meadows and pasture, mainly for low-intensity grazing. The substantial cattle industry contributes to the country's methane emissions. The carbon dioxide emissions...

Global Warming

The effects of global warming on the ITCZ could be significant. Given that surface winds over the ocean tend to follow ocean currents, changes in the circulation of ocean currents brought about by global warming will also have a direct influence on the ITCZ, resulting in an intensification of precipitation in the ITCZ, according to S. Nawrath and A. Lever-mann. A simulation model of global warming (using a general circulation model, or GCM, with enhanced carbon dioxide, or CO2), indicates an...

Types Of Waste

Litter is waste material dumped in public places such as streets, parks, picnic areas, bus stops, and near shops. The accumulation of waste threatens the health of people in residential areas. Waste decays, encourages household pests, and turns urban areas into unsightly, dirty, and unhealthy places to live in. The following measures can be used to control land pollution. Anti-litter campaigns can educate people against littering, organic waste can be dumped in places far from residential...

Luxembourg

The impact of climatic changes on the lithosphere and ocean has also been the subject of recent research at LSU, in the tradition of R.J. Russell, James P. Morgan, and J.M. Coleman. For example, Mike Blum has investigated responses of large river systems to climate and sea-level change. Patrick Hesp's research on changes to barrier-island ecosystems under climatic forcing mechanisms also falls within this realm. Likewise, Gregory Stone has analyzed the effects of tropical cyclones and winter...

The Diminution Of Natural Resources

The history of cod fishing in the Atlantic Ocean is a graphic example of the abundance of resources available in past centuries and the way in which those resources have been enormously diminished within the last century. For hundreds and in some cases thou sands of years, the ability of man to harvest resources, renewable resources in any case, was exceeded by the fertility of nature in replacing them. The development of industrialized harvesting techniques succeeded not only in depleting the...

Global warming and politicizing science

The NAS's reputation in research and the dissemination of information about global warming and climate change precedes its accolades for its museum exhibits about climate change. In 1991, the NAS released a report, Policy Implications of Greenhouse Warming, calling for a decrease in the dependence on fossil fuel, the advancement of nuclear and solar energy technologies, and the promotion of energy conservation, all aimed at a reduction in greenhouse gas emissions. The NAS asserted that the...

Phanerozoic Climate Change

Phanerozoic Glaciation

542 500 450 400 350 300 250 200 150 100 50 This figure shows the long-term evolution of oxygen isotope ratios during the Phanerozoic eon as measured in fossils, reported by Veizer et al. (1999), and updated online in 2004 1 . Such ratios reflect both the local temperature at the site of deposition and global changes associated with the extent of continental glaciation. As such, relative changes in oxygen isotope ratios can be interpreted as rough changes in climate. Quantitative conversion...

Ice Albedo Feedback

ALBEDo Is AN estimate of the reflectivity of a surface. The sun produces solar radiation in wavelengths that can be reflected off of many of the Earth's surfaces, some more so than others. The albedo of Earth is estimated as the ratio of the outgoing solar radiation (250-2500 nm.), and the incoming solar radiation. A surface that is perfectly reflective (all incoming light is reflected back again) would have an albedo of 100 percent reflection, or, as a ratio, 1.00. A surface that has no...

Global Climate In Cretaceous

THE CRETACEOuS Era spanned the time period from 144 to 65 million years ago. It was the final epoch of the dinosaurs. It ended when the dinosaurs became extinct. At its height, the Cretaceous was a period of great warmth. The poles were ice-free, and warm ocean currents spread from the equator to the poles. The concentration of carbon dioxide was higher than it is today, causing a greenhouse effect. The abundance of plants was not enough to lower the amount of carbon dioxide in the atmosphere....

Jule Gregory Charney was born in San Francisco, California, on January 1, 1917, to Ely Charney and...

Milankovitch Cycles

The Earth's orbit around the sun is slightly elliptical. Over time the gravitational pull of the moon and other planets causes the Earth's orbit to change following a predictable pattern of natural rhythms, known as Milankovitch cycles. Over a 100,000 year cycle the Earth migrates from an orbit with near-zero eccentricity (a perfect circle) to one with approximately 6 percent eccentricity (a slight ellipse). In addition, the tilt of the Earth axis, known as its obliquity, varies from 21.5 to...

Tsunamis

Tsunamis (sometimes called seismic sea waves) are large sea waves that are created by underwater earthquakes, volcanic eruptions, or even nonseis-mic events such as landslides and meteorite impacts. Tsunamis are also known as tidal waves, even though this is a misnomer because the waves have nothing to do with tides. The word tsunami is a Japanese word meaning harbor wave. Tsunamis are not easily seen on the open water, as they have extremely long wavelengths on the order of tens of kilometers....

Cooperative Institute for Arctic Research

THE COOpERATIVE INSTITuTE for Arctic Research (CIFAR) was created in 1994, at the University of Alaska following several years of teamwork between the university and the National Oceanic and Atmospheric Administration's (NOAA) Environmental Research Laboratories (ERL).

Portugal

As reported IN a major collaborative international research project, named SIAM II, Portugal is one of the European countries that are expected to suffer from the most extreme consequences of global warming and climatic change. These consequences are expected to entail three major geological effects in Portugal. First, due to the rise in sea levels, studies predict an increase in the erosion of Portugal's coastal areas. Second, scientists anticipate increased levels of rain precipitation and...

Food Miles

REcENT Years Have seen increasing concern about the long-term sustainability of food systems and their unintended side effects that can be imposed on the global environment and human wellness. Food miles are an appraisal of the distance a food or beverage travels from field to plate. While the cost of making things has never been cheaper, the cost of moving them around has never been as high, and it is getting higher. This is partly a consequence of outsourcing practices involving industries...

Oil Consumption of

IN 1970, THE United States became unable to meet its total oil energy needs, and became an oil-importing nation. Until then, American oil fields in Texas, Louisiana, and California had been able to meet the national need. By 2012, it is likely that the world as a whole will consume around 100 million barrels of oil per day. Humans have known about oil and some of its uses for millennia, but it only became identified as a consumable unit, in terms of extraction, refining, and then commercial...

Renewable Energy Sources As An Alternative To Nuclear Power

New Nuclear Construction Global Picture

Building and commissioning massive, complex nuclear plants requires huge government subsidies. Contrast this with wind or solar energy that are distributed and less dense supplies of energy. The amount of solar panels produced on an annual basis is equivalent to the construction of two nuclear facilities. The renewable solar approach seems simpler and safer, and not one requiring subsidies. Such sound Approximately 30 new nuclear power plants are under construction and another 200 are in the...

Impact of climate change

Ohio experienced the effects of higher temperatures in 1993. While other states flooded, Ohio had the driest August on record since 1895. While climate models vary on the amount of temperature increase possible, potential risks include having decreased water supplies, increased risk for wildfires, population (both human and animal) displacement, changes in food production (with agriculture improving in cooler climates and suffering in warmer climates), and changes in rain patterns to downpours,...

Nuclear power and the environment

As a stand-alone device, nuclear reactors do not emit greenhouse gases. The nuclear reaction is contained and the heat generated is used to boil water to turn turbines and produce electricity. Instead of a chemical reaction, an atomic reaction is required, produced by a process of fission using uranium fuel. Due to the splitting of atoms and the radioactive movement of neutrons, no carbon dioxide, methane, or other greenhouse gases are produced. However, the byproducts are toxic, radioactive...

Oceanic Changes

Oceans ARE CONNECTED bodies of saline water that cover about three-quarters of the Earth and comprise more than 97 percent of the world's total water resources. Although continuous, the global ocean is divided into five oceans based on geographic location, geological barriers, and other criteria, into the Arctic, Atlantic, Indian, Pacific, and Southern oceans. Oceans have great influence on global weather patterns and climate. This influence stems from variations in ocean temperature caused...

The relationship of oceans with other aspects of the Earth's environment is also highlighted in oceanographic studies. Biology, chemistry, geology and physics together...

THE FuTuRE oF NucLear Interests

Safety concerns aside, the perceived atmospheric-friendly power produced by nuclear means that the next few decades for nuclear power generation and production of uranium are solid. Approximately 30 new nuclear plants are under construction and another 200 are in the planning phase around the world. Even the nuclear reticent United States has 49 such facilities in the planning stages, the last one was approved almost 30 years ago in 1979. The resurgence of nuclear power, owing directly to...

Carbon Cycling

The past two centuries have witnessed a significant rise in the amount of global carbon emissions and subsequent absorption by oceans around the Earth. The global ocean plays a vital role in the Earth's carbon cycle, about 50 times greater than that of the atmosphere. The oceans absorb from the air about half of carbon deposits from fossil-fuel burning sources. The ocean contains the largest pool of carbon on the Earth's surface however, these carbon concentrations are not distributed equally....

Ocean Ecology

Oceans are home to the majority of plant and animal life on the planet. Climate change is expected to alter marine ecology both directly, through lower pH and elevated temperatures on the organismal level, and indirectly, via changes in community dynamics and food and habitat alteration on the aggregate level. A major concern is the possible effect climate change may have on ocean productivity. Phytoplankton, small plants found near the ocean's surface that comprise the basis for the marine...

Thermocline

THE THERMoclINE is the region of the ocean where temperature decreases most rapidly with increasing depth. It separates the warm, well-mixed upper layer from the colder, deep water below. A thermo-cline is present throughout the year in the tropics and middle latitudes. It is more difficult to discern in high latitudes, where temperature is more uniform with depth. The presence of a very shallow thermocline in the eastern equatorial Pacific Ocean has important implications for global climate....

The Humanenvironment Relationship

Two major paradigms have animated theories of the conceptualization of the relationships between humans and the natural environment environmental determinism and possibilism, even though other debates in the social sciences should not be dismissed. Environmental determinism holds that the physical environment is a factor that shapes human occupation of the land and the use of resources, determining the course of history, the culture of an area, the settlement pattern, and human behavior. The...

Temperature Increase wC

This figure shows the predicted distribution of temperature change due to global warming from the Hadley Centre HadCM3 climate model. These changes are based on the IS92a (business as usual) projections of carbon dioxide and other greenhouse gas emissions during the next century, and essentially assume normal levels of economic growth and no significant steps are taken to combat global greenhouse gas emissions. The plotted gray tints show predicted surface temperature changes expressed as the...

Singapore

THE REPUBLIC OF Singapore covers the main island of Singapore and 57 outlying islands, most of which are uninhabited. It covers a land area of 270 sq. mi. (704 sq. km.) and has a total population of 4,680,600 (July 2003 est.). This means that Singapore has one of the highest population densities in the world more than 17,335 people per sq. mi. (6425 people per sq. km.). Combined with a high standard of living, Singapore has a high per capita emission level of carbon dioxide, with 15 metric tons...

Resource Allocation

Given that resources are, by definition, finite and scarce in nature, then there must be some mechanism to allocate different shares to different sets of people. Allowing everyone who has an interest in resource exploitation to do so as freely as desired will lead to disastrous depletion of the resource. Consequently, the basis of allocation must be determined. In mature, democratic societies, coalitions of interests will help to set the agenda by which resources are allocated. This can be...

Programs

In 2006, the governor of Minnesota proposed the Next Generation Energy Initiativem designed as a means of developing strategies for focusing public attention on renewable energy, energy conservation, and the need to lower carbon emissions. The following spring, the state created the Minnesota Climate Change Advisory Group (MCCAG), composed of 51 individuals representing business, utilities, environment, academics, religious organizations, the private Although Minnesota is known as the Land of...

Precipitation Patterns

Changes in precipitation patterns foreshadow potentially substantial effects on ecosystems and human communities, including wetlands, lakes, rivers, agriculture, and domestic use. Measures to improve efficient water use, manage water demand, reuse water, and expand water resources can all improve resilience. Such measures include differential pricing structures, permitting, and requirements for water-conserving techniques. Adaptive water management, though still a developing field, is equally...

Pew center on global climate change

In 1998, with a grant from the Pew Charitable Trusts, and within the context of increasing concern over the impact of climate change, the Pew Center on Global Climate Change was established. It is a nonprofit, nonpartisan, independent organization. The role of the Pew Center is to build a bank of credible information about climate change and its impacts, and to try to provide solutions to the problems created by climate change. The Pew Center aims to provide an objective forum for research, and...

Nuclear power

Bush, in a June 2005 speech delivered to a group of nuclear power plant workers intoned, The 103 nuclear power plants in America produce twenty percent of the nation's electricity without producing a single pound of air pollution or greenhouse gases. Experts in the nuclear energy field, both for and against nuclear energy, find this statement lacking credibility. Nuclear energy critics cite the significant amount of greenhouse gases produced by the nuclear fuel cycle in...

Nitrous Oxide

NITROUS OXIDE (N2O) is a compound of two very abundant elements on Earth, which also compose most of the gases in the Earth's atmosphere oxygen and nitrogen. It is a colorless gas with a sweetish odor. It is known by the common name of laughing gas. It occurs naturally, and has been implicated as a potentially significant agent in global warming. Joseph Priestly first synthesized it in the 1770s. Dentists and physicians have used it as a mild anesthetic for decades. It was first used in...

Needs and Wants

THE CONCEPT OF needs and wants and the ability to distinguish one from the other plays an important role in society. The issue is explored in philosophy, psychology, ethics, and modern social thought. To assert that something is a need is to argue that it is an essential element that is required for the body or society to exist. Some philosophers call needs real goods, and wants apparent goods. In Western political thought, the goods of having, doing, and being are seen as needs. The good of...

Nauru

THE Republic of Nauru, located in the Pacific, has a land area of 8.1 sq. mi. (21.2 sq. km.), a population of 10,000 (2006 est.), and a population density of 1,608 people per sq. mi. (621 people per sq. km.). With very little arable land, Nauru is completely dependent on imported food and water. Nauru makes its money from the sale of phosphate, which has led to the destruction of much of the country, and during the 1970s and 1980s, incredible wealth. Electricity production in Nauru comes from...

Monsoons

A MONsOON Is any wind that reverses direction seasonally. These occur in many parts of the globe, but the most famous is the Indian monsoon wind. The name monsoon is an adoption of the Arabic word mausim, which means season. For centuries, Arab sailors took the seasonal mausim as a wind that would carry them to India and beyond. The term was originally applied to the Indian monsoon. However, as the phenomenon came to be studied more thoroughly, the term monsoon has been applied to other annual...

Moldova

Located IN eastern Europe, the Republic of Moldova, formerly a constituent republic of the Soviet Union, has a land area of 13,067 sq. mi. (33,843 sq. km.), with a population of 3,794,000 (2006 est.), and a population density of 339 people per sq. mi. (111 people per sq. km.). Approximately 46.7 percent of the population lives in urban areas. Fifty-three percent of the land is arable, a further 13 percent is used as meadows and pasture, and 8 percent is forested. In 1990, Moldova had a per...

Its capital and largest city is Kiev (50 degrees 27 minutes N, 30 degrees 30 minutes E, population of 2.6 million in 2007, estimation by the Department of Ukrainian State Statistics). The total area of Ukraine is 233,090 sq. mi. (or 603,700 sq. km., the 44th country in size and second in Europe after European Russia). The total population is around 46.6 billion (in 2007, estimation by the Department of Ukrainian State...

From Hothouse To Icehouse

Abrupt cooling at the Eocene Oligocene transition (35 million years ago) marked the appearance of the first continent-spanning ice sheet on Antarctica, potentially the first Cenozoic Northern Hemisphere ice sheets, and the transition from hothouse to icehouse climate in the Cenozoic. However, much of the planet continued to experience climatic conditions warmer than the present, with cool temperate Research on the early Cenozoic era, when tropical forests grew in Wyoming, is revealing new...

Western Boundary Currents

WESTERN BOUNDARY CURRENTS are intense jet currents at the western periphery of large-scale oceanic gyres in the World Ocean. As was shown in the pioneer paper of Henry Stommel in 1948, they are the result of two causes the so-called p-effect (this term has arisen from traditional representation of Corio-lis force, f, in the following form f f + py, where f is a Coriolis parameter at a definite latitude in other words, the p-effect is to the result of the spherical form of the Earth turning...

The governing body of the three campuses is the board of trustees. The campus at Urbana-Champaign is known as the U of I and UIUC, whereas the Chicago campus is known as UIC, and the Springfield campus UIS. The largest university in the Chicago area, UIC has 25,000 students, 15 colleges, including the nation's largest medical school, and annual research...

World Wildlife Fund

Although the world Wildlife Fund around the world has changed its name to the World Wide Fund for Nature, the original name remains the official one in the United States and Canada. As an international nongovernmental organization, it was founded in 1961 in Switzerland to help with the conservation, research, and restoration of the natural environment, changing its name in 1986, although still keeping its initials (WWF) around the world. Although over many years the WWF became famous for its...

Adaptation

Adaptation in social, cultural, and economic contexts is also an important component of thinking about societal response to climate change. As such, adaptation is defined in many ways. It can be defined as a process that enables people to minimize the adverse effects of climate on their health and well-being. It also refers to the capacity of people or societies to take advantage of the changes that the climate might provide. Adaptation can also mean the adjustments in behavior and economic...

Atmospheric Vertical Structure

THE ATMOSPHERE COMPRISES the thin envelope of gases held by the Earth's gravitational force. Extending for several hundred miles above the Earth's surface with no clear boundary, the atmosphere is often sub divided into vertical layers according to a distinctive physical properties. These properties include thermal characteristics, chemical composition, electrical attributes, or density. The vertical structure of the atmosphere is defined by changes in these physical properties, with each...

Criticisms Of Ngos

The NGO movement, however, is not without its critics. Many question the accountability of NGOs. For example, the work undertaken by World Vision, in coordinating the relief effort resulting from the Tsunami in South East Asia in 2005, has sustained attacks that the donated monies, millions of dollars in this case, were not reaching the intended victims. Many NGOs working in developing countries are partly funded by their own governments, and have been criticized as being a front for foreign...

Agricultural Solutions To Climate Change

There are many strategies that farmers, businesses, and consumers can adopt to reduce greenhouse gases related to agriculture. First, farmers can replace fossil fuels such as gasoline and diesel with biofuels such as ethanol or biodiesel. Ethanol is a fuel alcohol that is produced by a fermentation process that uses yeast to convert the sugars found in plants into a combustible alcohol fuel. Ethanol can offset varying amounts of fossil fuel-generated carbon dioxide depending on the material...

Atmospheric Absorption of solar Radiation

Solar radiation is radiant energy emitted by the Sun. The process begins at the Sun's core, where hydrogen atoms are fused to helium atoms via nuclear fusion. For each second of nuclear fusion, the Sun converts 700 million tons of hydrogen into 695 million tons of helium, with 5 million tons of electromagnetic energy radiating out into space. Some of this energy travels the approximately 92.89 million mi. (149.5 million km.) across the solar system to Earth. The importance of the Sun to Earth...

Afforestation

Afforestation involves taking action to plant trees in an area that has never been a forest area or to restore a deforested area. The trees may be planted from seeds or from seedlings. Legally, afforestation includes the setting aside of forest land, or land to be reforested by law. Many national forests have been created in the last century. These forest On some land, such as this farm in Israel, afforestation will not occur naturally and requires mass planting programs. On some land, such as...

Climate Extremes

This panoply of proxy climate indicators records a startling array of paleoclimates in Earth's history. Climatic conditions on Earth have ranged from extreme icehouse conditions with, potentially, the entire planet covered in glaciers (a paleoclimate known as Snowball Earth) to extreme hothouse conditions, with atmospheric carbon dioxide concentrations as much as 20 times higher than those at present, and tropical forests extending nearly pole to pole. Earth's climate has also apparently...

Gulf Stream Origins

The origin of the Gulf Stream is debatable. One group of scientists believes that the Gulf Stream is driven both by the rotation of the Earth and by a deep-water current called the thermohaline circulation. Another group of scientists accept the theory propounded by Henry Stomme in 1948, that the Gulf Stream is a wind-driven phenomenon. Heating and cooling affect its temperature and other properties, but not its basic existence or structure. Stomme theorized that as long A NASA satellite image...

Emission Trading Systems

The European Union Emission Trading Scheme (ETS) is an example of a carbon permits trading system. The test phase of ETS operated from 2005-07, and is slated for operation in the European Union (EU) during the Kyoto commitment period 2008-12. In the system, the aggregate cap on emissions is set by each EU government agency, and the total number of emissions allowances is defined to provide the owner the right to emit units of emissions. The amount of emissions is capped, whereas the permit...
