* What is the greenhouse effect, and how does it work?
The greenhouse effect is when the short wave lengths of visible light from the son pass through a transparent medium. They are then absorbed but the longer wavelengths of the infrared re-radiation from the heated objects are unable to...
precursors, are emited by natural sources such as volcanoes and decaying vegetation. Man-made
sources are also primary causes for emissions of sulfur dioxide and nitrogen oxides that come from
fossil fuel combustion. The most common emiters of these fossil fuels are power plants, factories
used in the context of pollution emissions that are produced as a result of human activities but applies broadly to all major human impacts on the environment.
The application of technology (in general) often results in unavoidable environmental impacts, which according to the I=PAT equation...
increase in the average temperature of both the earth’s near surface air and the oceans. The temperature increase began in mid twentieth century and is predicted to continue into the future. For example, during the last hundred years ending in 2005, the earth’s surface air temperature has increased drastically...
Researchers aim to cut carbon-dioxideemissions by shedding light on the nanostructure of cement.
Concrete is the most widely used man-made material, and the manufacture of cement--the main ingredient of concrete--accounts for 5 to 10 percent of all anthropogenic emissions of carbondioxide, a leading greenhouse...

Though there is some scepticism that climate change is a result of human actions, it is unlikely to be a natural event. Some dismiss the phenomenon known as “global warming” as a hoax, and claim that yuppies driving SUVs could not possibly change the overall temperature of the earth. In a sense, this...
Every year, almost 7 billion tons of carbondioxide is released into the atmosphere by human activity. That is the equivalent of 107,700,000 jet airplanes being in the air at once! This harrowing figure is the main cause of global warming, and has been increasing for the last 50 years...
CLIMATE CHANGE AND CARBON TRADING: NEW AVENUES FOR ACTUARIES
(Submitted By: Anupam Sharma, Deepa Gupta, Subhash Goyal, Swati Kwatra)
The increasing risk of Climate change can be measured by the fact that natural catastrophes in 2008 cost the global economy $225 billion, which is...
Eleven of the twelve hottest years on record occurred between 1995 and 2006, which further illustrates the impact of global warming on the environment (What is Global Warming, 2007). According to U.S. Geological Survey predictions, glaciers at Glacier National Park will all disappear by the year 2030 (Global...

Global warming is too serious for the world any longer to ignore its danger or split into conflicting...

The study predicted an increase in vehicle kilometres travelled of 57% (central scenario) from 1996 to 2031; the increase being predominantly due to a rise in private...

Here are a few of the main causes of air pollution:
Manufacturing facilities, power plants, and waste incinerators are all industries that emit high levels of carbon monoxide, organic compounds, and chemicals into the atmosphere, just to name a few. Possibly...
The purpose of this essay is to consider the current environmental issues of an enhanced greenhouse effect and global warming with particular reference to the changes that are taking place in response to Greenhouse Gases interacting with the atmosphere and the effects these changes are having on naturally...
Precipitation has risen in some parts of the and has completely fallen in other parts of the African continent, leading to cases of hunger, outbreak of diseases draughts and flooding. What has caused these changes in climate? The main causes of climate change include emission of carbondioxide into the atmosphere...
implementation. Some of these challenges include the argument that though Annex 1 countries have agreed to achieve the Kyoto target 5% reduction in their 1990 levels of greenhouse gas emissions by 2012, it is no more than a pinprick in the menace of climate change. The Kyoto figures also exclude emission from aviation...

Global warming is one of the most controversial environmental issues to confront our world in the last few decades. As the ozone layer has been depleted through the release of carbondioxide gases causing global warming there are still those who question whether global warming even exits, and if it does...
