The Greenhouse Effect and the Ozone Layer

We have all heard, at least once in our lifetime, that the world is going to end for various reasons, but we never treat it seriously and push it aside as another media stunt. But the thing that will eventually end the world as time passes, which needs to be given serious attention by everybody, is Globalisation. Globalisation comes in different forms, from cutting down trees, to burning fossil fuels, but I have chosen a few main problems to talk about. Greenhouse gases that are causing global warming, and the hole in the ozone layer, and try to talk about what they are, problems they cause, the concerns they arise, and possible solutions.

   We have all heard about Global Warming, but what does it mean? Well, the sun heats the world, but why is it warmer on earth than in space? To understand what controls temperature on earth, we have to understand the Greenhouse effect.

   So by now we can tell that it is the energy sector that contributes most to Global Warming. We could therefore reduce emissions by reducing the amount of energy that is consumed. This can be achieved in several ways; one way is to tax energy to make it more expensive so people and industries use less. Another solution is to find ways of producing electricity and power from renewable energy sources; an example is wind power. Thankfully the European Union encourages research into these new methods. We can also increase efficiency of things that use energy. For example, more efficient cars would run on less petrol. The problem with this solution is that it may not be enough, because more people are using cars globally, so this will cancel out the impact of more efficient motors. All in all, a combination of these solutions is probably the answer. But we should each work independently, being responsible for our world, by reducing energy consumption and being careful about how we use it.

   Since we know which gases harm the Ozone layer, mainly those containing chlorine and bromide, the simplest solution would be to eliminate the use of these gases. However, the harmful gases have a wide range so banning them is a slow and difficult process. CFCs are now banned except for critical use such as in asthma inhalers and aircraft fire extinguishers. HCFCs and methylbromide are also being phased out. But don’t take this too lightly, the total elimination of these substances is urgent. Every five-year delay adds 18 years to the destruction of the Ozone layer!

   Research is also ongoing into alternative Ozone friendly technologies. In fact, the European Union funds the world’s most important Ozone research program.

   The best way the majority of the people can deal with the situation of globalisation, is to research and educate ourselves, and to try to learn as much as we can about the problems that effect us the most, and then try to find our own way of dealing with the problems. image00.png

    Global Warming - Is it man Made?

    According to a study by NASA in 2005 was the year with the highest average temperature for 100 years. The five warmest years since the beginning of the temperature record are in the last decade. Especially threatening: the mountain and polar regions warm more than other areas.

    This is done through the use of rockets. Throughout the life of the satellite the orbit and attitude, the direction it points, must be adjusted. Generally they have on-board rockets for this purpose. Sometimes the rocket may be fired to accelerate the satellite and move it to a higher orbit or to decelerate the satellite and move it to a lower orbit.

    Most scientists agree that the global temperature is rising. They do not agree on more specific elements of the issue: How much will it warm up? What will happen if it does warm up? How far are humans responsible? What should we do to stop it? Scientists believe that if we go on producing gases at the rate we

    This means that the land beneath can still be used for farming. The advantages of using wind power are that it doesn't produce any waste or greenhouse gases and it's free. Wind turbines are a good method of supplying energy to remote areas.

  1. The greenhouse effect

    ground surface to once again radiate repeating the cycle described above, again and again, until no more longwave is available for absorption. The amount of heat energy added to the atmosphere by the greenhouse effect is controlled by the concentration of greenhouse gases in the Earth's atmosphere.

  2. Sustaining life on Mars - the survival of the human race.

    Mars is even more than that of Earth because, there are currently no oceans, lakes, or rivers. The master plan would fill up about %25 of the planet with ocean, which is necessary to ensure plant life, which will be used for oxygen.

  1. Greenhouse Effect.

    This process works by the principle that certain atmospheric gases, (or greenhouse gases) allow short wave radiation from the sun to pass through them unabsorbed, while at the same time absorbing some of the long wave radiation reflected back to space.

    Most chemicals, when released into the atmosphere get rapidly broken down into smaller, harmless components by reactions in the lower atmosphere. The CFCs however, are so stable and unreactive that they survive to reach the highest levels of the atmosphere, and become globally distributed in the stratosphere.
