Greenhouse Gases: Carbon dioxide (CO2) is a greenhouse gas in the atmosphere that may raise average temperatures on Earth. The burning of fossil fuels could be responsible for the increased levels of carbon dioxide. If current trends continue‚ future concentrations of atmospheric carbon dioxide in parts per million (ppm) could reach the levels shown in the accompanying table. The CO2 concentration in the year 2000 was greater than it had been at any time in the previous 160‚000 years. Year 2000

INTRODUCTION [SLIDE 2] Many chemical compounds found in the Earth’s atmosphere act as “greenhouse gases.” These gases allow sunlight to enter the atmosphere freely. When sunlight strikes the Earth’s surface‚ some of it is reflected back towards space as infrared radiation (heat). Greenhouse gases absorb this infrared radiation and trap the heat in the atmosphere. Over time‚ the amount of energy sent from the sun to the Earth’s surface should be about the same as the amount of energy radiated back

The greenhouse effect in is the entrapment of the sun’s heat energy in the earth’s atmosphere. Greenhouse gases such as carbon dioxide‚ water vapor‚ methane‚ and nitrous oxides are all gases that contribute to this phenomenon. Carbon dioxide is the most abundant greenhouse gas while water vapor the least harmful gas makes up less than one percent of the gases in the atmosphere. These greenhouse gases are produced naturally by the earth for example carbon dioxide‚ and methane is produced from the

Final Draft Do you ever wonder why last summer was one of the hottest summers worldwide on record or why some recent winters have been among the warmest ever recorded? Do you also wonder why disastrous weather events like super-storm Sandy continue to increase in their frequency and severity? Many modern scientists attribute these dangerous environmental trends of global warming to the ‘greenhouse effect’. The ‘greenhouse effect’ results from greenhouse gases such as carbon dioxide

Well‚ based on my research‚ wind energy is the result of the sun’s energy interacting with the earth’s surfaces. It is also an ideal renewable energy source that is infinitely sustainable; pollution free; doesn’t use fuel; and doesn’t produce greenhouse gases‚ toxic or radioactive waste. This type of energy is considered a green power technology because it has minor impacts on the environment. When using wind to generate electricity we use machines known as turbines and this turbines use blades that

Introduction: The presence of greenhouse gases in the Earth’s atmosphere last year reached its highest levels since pre-industrial times‚ a report released by the United Nations World Meteorological Organization (WMO) warns recently. Even if we managed to halt our greenhouse gas emissions today‚ and this is far from the case‚ they would continue to linger in the atmosphere for decades to come and so continue to affect the delicate balance of our living planet and our climate. The latest

Greenhouse gases Carbon dioxide is a colourless‚ odourless gas that makes up .04 percent of the earth’s atmosphere. It’s released by the breakdown of organic materials‚ by animals when they respire‚ and by the burning of fossil fuels. Carbon dioxide isn’t toxic—after all‚ we exhale it with every breath and use it to make our drinks fizzy. However‚ carbon dioxide is considered a pollutant because‚ as a greenhouse (heat-trapping) gas‚ it’s a significant contributor to global warming. In the last 150

What are Greenhouse Gases? These are the gases that make up our atmosphere: Carbon Dioxide 89% Methane 7% Nitrous Oxide 3% Halocarbons 1% What is the Greenhouse Effect? The Greenhouse Effect is the way that gases in the atmosphere trap heat from the sun. They let heat in‚ but prevent most of it from escaping. It is essential for life because we need a certain amount of radiation to heat up our atmosphere. What human activities produce Greenhouse Gases? By burning fossil fuels such as coal‚ oil and

the greenhouse gases? There are four greenhouse gases that trap and absorb heat on Earth so living organisms can sustain life. Not only are they the greenhouse gases up also make up the 1% in the atmosphere. The greenhouse gases include water vapor (H2O)‚ carbon dioxide (CO2)‚ methane (CH4)‚ and nitrous oxide (N2O).
