Earth global warming, any solutions?

Résumé du document

One of the most important ecological problems of the last decade is the global warming of the earth, in fact most scientists agree that the earth has gained about one half to one degree Fahrenheit. The consequences will be dramatic: floods, enormous storms, catastrophic ecological changes. For example the Kilimanjaro ice cap has lost about 80% of its volume during the last twenty years, floods are becoming more and more frequent and destructive all over Europe. Everyone in the world, individuals and firms, should take responsibility for reducing global warming, and know the different solutions available in order to apply them. In the industrial domain, the main solutions are partnership programs, the use of clean energy and energy efficiency increase. The individual solutions are waste management, energy home saving and transportation.
The problem of the warming of the earth comes from the well-known greenhouse effect. When some specific gases (carbon dioxide, methane, nitrous oxide, and many others in low concentrations) are emitted into the atmosphere, it increases the reflection of sun rays against the clouds, and as a result the air is warmer.

Extraits

[...] In developed countries, the governments could oblige everyone to act now against the global warming, for example by voting new laws. More conferences like the one in Kyoto should be organised to push governments to act more quickly. It is not too late to reverse the tendency of rising temperatures, and prevent all its dramatic consequences. Every sector can act industries, individuals and governments should be informed by organisations about the severity of the problem, and what solutions to apply. [...]

[...] This label requires that the products energy efficiency exceed of about 13 to 15% the federal laws.[xi] These laws deal with the amount of energy used by a device, and its efficiency. Using long-lasting compact fluorescent bulbs for example can save as much as 30 percent in heating and cooling costs.[xii] But this label is not the unique solution, and improvements in transportation could be beneficent for reducing global warming. According to the EPA, and the Sierra Club the most important is transportation. Indeed all vehicles release the greatest amount of greenhouse gases in the atmosphere and the U.S. is the greatest source of these gases. Transportation in the U.S. [...]

[...] The main problem in the 70s was the cost of setting up a new heating or new production section in a factory. Now more and more companies are equipped with solar panels or windmills because these clean energies are now very competitive compared to fossil fuels energy production. Hydropower, which consists of using tide and wave power, is a bit different since it can only be used near rivers or seas. As a consequence, firms cannot use this means of producing energy, and companies need to be created to produce electricity, similar to Hoover Dam on the Colorado River. [...]

[...] (see figure The problem with SUVs is their license to guzzle more gas and pollute more than other cars. This license was voted in 1975 during the energy reduction campaign, but SUVs were not well developed and represented about 20% of all vehicles and they are now about half of it, that's why the law is now outdated. One solution to the problem of cars that use too much gas, and so emit too much CO2, is to change laws to oblige car manufacturers to improve the mileage of their cars. [...]
