Global Warming The greenhouse effect‚ in environmental science‚ is a popular term for the effect that certain variable constituents of the Earth ’s lower atmosphere have on surface temperatures. It has been known since 1896 that Earth has been warmed by a blanket of gasses (This is called the "greenhouse effect."). The gases--water vapor (H2O)‚ carbon dioxide (CO2)‚ and methane (CH4)--keep ground temperatures at a global average of about 15 degrees C (60 degrees F). Without them the average

GLOBAL WARMING : WHAT LIES AHEAD GLOBAL WARMING Climate change is a change in the statistical distribution of weather over periods of time that range from decades to millions of years. In recent usage‚ especially in the context of environment policy‚ it is more generally known as "global warming"‚ which occurs due to increasing levels of greenhouse gases in the atmosphere. Most of the observed temperature increase has been caused by increasing concentrations of greenhouse gases‚ which result

Abstract What is global warming? Global warming is the heating of the earth. Global warming happens when greenhouse gases such as carbon dioxide‚ water vapor‚ nitrous oxide‚ and methane trap heat and light from the sun in the atmosphere. This is known as the greenhouse effect. It prevents heat and light from escaping the earth’s atmosphere kind of like the earth is a giant greenhouse. Global warming is a good thing‚ but at the same time‚ can have devastating effects if not properly monitored and

Introduction A Global Warning: Global Warming | The world is warming dangerously. It depends either on the natural causes or the artificial causes like human based greenhouse gases. This affects both the vegetation and zoological environment and also the human | life. Its effects are gradually increasing every year.The purposes of our project are:·To investigate the causes and the effects of global warming and to present the results of our survey.·To attract attention on the solution proposals about

The earth can be kept healthy and exist longer without global warming. Global warming is becoming a popular topic around the world. “Global Warming and the Greenhouse Effect” discusses what global warming is. This is how global warming is caused. Energy travels from the sun to the earth to heat it. The earth then radiates energy back into

It can be misleading and can easily be taken to be some other ad. * Although the liner used i.e. ‘if we don’t act now‚ the future looks blue’ is very catchy and hard hitting its effect

What is the main cause of global warming? In the last century‚ the sea level has rose for about 17 centimetres. The rate in the last decade is however‚ nearly the double of last century. Major global surface reconstructions also showed that the Earth has warmed since 1880 and it’s still going on. Oceans are also warming up‚ due to the heat. Not only that‚ the Greenland and Antarctic ice sheets are melting‚ glaciers are disappearing and extreme weather events have occurred more often. All these

The changes in the surface air temperature‚ referred to as the global temperature‚ brought about by the enhanced greenhouse effect‚ which is induced by emissions of greenhouse gases into the air. How Global Warming Works Carbon Dioxide (CO2) Fossil fuels (coal‚ oil‚ natural gas) Example of the Greenhouse Effect The Sun’s energy passes through the car’s windshield. This energy (heat) is trapped inside the car and cannot pass back through the windshield
