Question

Write a one page essay about what you know about the "greenhouse effect" using other resources (cite any external resources), be sure to talk about what it is, how it works, what gasses are involved, what it contributes to, etc. (You must answer these questions). In addition, watch the video on Greenhouse gases below. After watching the video be sure to answer these questions as well. What do the scientist remark about vegetation and greenhouse gases? Based on this, what ideas can you come up with to help solve the problem of greenhouses gases. This assignment should be 3/4 to 1 page in length and must be written using full sentences and complete paragraphs. Point form is not permitted. http://video.nationalgeographic.com/video/greenhouse-gases

Explanation / Answer

The greenhouse effect may be defined as warming of the earth’s climate owing to the increased concentrations of CO2 and some other gases in the atmosphere.Greenhouse Effect This effect is the result of certain atmospheric gases letting sunlight through to the earth's surface, while not letting energy radiated outward from the earth's surface. This results in a net buildup of solar energy in the Earth's atmosphere because the flow in is greater than the flow outwards

Causes: There are many causes of the greenhouse effect. The destruction and cutting down of tropical rainforests, vehicles that clog up city streets, the rapid growth of population, the use of chlorofluorocarbons in packaging and manufacturing commercial products, the use of detergents, such as washing powder and washing-up-liquid and various kinds of environmental pollution are the causes of green­house effect. Carbon dioxide gas, produced by the burning of fossil fuels and forests and pollutants such as methane and chlorofluorocarbons also cause the greenhouse effect. In recent years there have been many alarming reports that the world’s climate is undergoing a significant change. All these reports provide strong evidence that world temperatures are increasing day by day. This increase in global warming is caused by increased amounts of carbon dioxide around the earth. Most climatologists believe that the greenhouse effect is the most likely cause of this global warming.

The Environmental Media Services Organization has found that the greenhouse effect could drive temperatures up as much as 6 degrees by the year 2100 - an increase in heat comparable to the 10-degree warming that ended the last ice age (Fast Facts). If a 10-degree warming was the factor that ended the last ice age, imagine what another warming could do. Consider hydrology, for instance. Warm air holds more water vapor than cold air, so there is an increase in evaporation in dry areas, and hence more drought - something that has been documented on every continent. Once that water is in the atmosphere, it's going to come down somewhere - and, indeed, we have seen the most dramatic flooding ever recorded in recent years. In 2004, 300 million humans, 1 in 20 of us, had to leave their homes for a week, a month, a year, or forever because of rising water(The Planet Speaks 124). Much of the gained water would be from melting icecaps in the ocean and melting glaciers on land. Coastal cities and islands could be wiped out

There are many negative environmental effects of global warming. Another effect is the fact that higher temperatures will lead to a change in the water cycle. Warmer temperatures will cause a greater amount of evaporation from lakes, rivers, streams, and oceans. In some areas, this could be good, but in other areas, it could be bad. In northern regions of the U.S., where we live, an increase in the temperature and the amount of rain could extend the growing season of crops. In turn, the farmers could make more money. It could also hurt some farmers though. There is a possibility that crops could get too much rain and crops could be killed. Certain areas would actually get less rain, which would lead to more droughts. Warm temperatures and wet weather would be the main result of global warming in certain areas, and warm temperatures and wet weather are factors that promote tropical storms. Thus, tropical storms would appear more often and with greater frequencies.

More rain as a result of global warming will also force plant life and its species to adjust their location. Species migrate naturally, but scientists say that global warming would cause them to migrate at a much faster rate. If the climate changes, some forest species in North America will shift by as much as 300 miles to the north (Campaign to Stop Global Warming). Plants will also be forced to migrate. If one region is getting more rain than another, plants that need more rain that is on the border of these two regions will naturally begin migrating into the region that is getting more rain.

For our survival, we need to add a strong voice to international advocacy for emission and control of greenhouse gases that are causing global warming by damaging the Ozone layer. The UN Secretary-General Kofi Annan had made a fervent appeal urging the USA to join other nations in reducing emissions and conserving energy. Nevertheless. Kofi Annan warns that climate change may be the greatest challenge, the next generation will face and Bangladesh has to heed it as this country probably has much more to lose from greenhouse gas effects than any other country in the world.
