ich suche dringend hilfe. Ich schreibe bald meine Prüfung und ich denke wir müssen etwas über Global Warming schreiben.
Ich habe mir den Kopf gemacht und schonmal einen Text zusammen geschrieben.
Da wollte ich euch fragen, ob dies ausreicht bzw. ob viele Aspekte getroffen wurden und ich nichts vergessen habe?
Vor allem ob da irgendwelche Fehler drin sind, oder unverständlich ist, guter Satzanfang etc.
Wenn ihr noch etwas dazu einfügen wollt, würde mir auch sehr helfen.
PS: eine übersetzung brauch ich nicht, wenn es jemand möchte, gerne!
Ich habe auch einige Sätze selbereingefügt, und auch einige gelöscht.
Vielen Dank

For 2.5 million years the earth's climate has fluctuated, cycling from ice ages to warm appearance. But in the last century the planets temperature has risen unusually fast.
Scientists believe it's human activity, that's driving the temperatures up.
Most of the increase is due to human activities, like:
-burning gasoline to drive cars and trucks
-burning oil, coal or wood to produce electricity and power plants
-for heating, cooling, and other purposes burning forests to clear land
A process known as global warming and that activities pollute the air, water and the earth
Ever since the industrial revolution begun, factories, power plants and eventually cars have burned fossil fuels: such as oil and coal.
Releasing huge amounts of carbon dioxide, exhaust fumes, emissions and other gases into the atmosphere. These greenhouse gases trap heat near the earth through naturally accouring process called the greenhouse effect. In that case, the warming effect is the reason for the vicious circle in the greenhouse.
The main gases that cause the greenhouse effect is the process in which the emission, exhaust fumes, water vaper, Co2, methane, nitrous oxide etc. of infrared radiation by the atmosphere warms a planet's surface. And that is a natural phenomenon based on the fact that the Earth's atmosphere acts a little like the glass of a greenhouse, allowing the heat of the Sun to enter, then capturing it.
The greenhouse effect begins with the sun and the energy that radiates to the earth.
The earth and the atmosphere absorbs 51% of the energy-rays while the rest is radiated back into space. Naturally accoring gases in the atmosphere trap some of this energy and reflect it back warm the earth. Also the sun's radiation radiates with UV-Rays into the earth and also to human beings or animals who can get a victim of skin cancer.
Scientist now believe that the greenhouse effect is being intensified by the extra greenhouse gases, that humans have released.
Scientists record that 1998 was the warmest year in measured history.
Meanwhile radiance taken from an ice core show the greenhouse gases carbon dioxide and methane have yet the highest levels in the past 420.000 years. As long as industrialize nations consume energy and developing countries increase there fossil fuel consumption.
The concentration of greenhouse gases in the atmosphere will continue to rise.
Researchers predict that temperatures will increase about 2 to 10 degrees farenheit By the end of the century, what's less certain is what rising temperatures mean for the planet. Others forecast rising sea levels which could flood cost areas around the world. The disappearance of ice cover has been dramatic in recent years, the arctic see ice is shrinking. According to NASA studies the extending see ice has declined about 10% in the last 30 years. The Arctic sea ice, which covers an area the size of united states; shrank by about 6 percent between 1978 and 1996 according to the world watch report, it lost an average of 34,300square kilometers a year, an area larger than the Netherlands.
In this case, melting glaciers can cause serious floods. One example of this occurred in Nepal in 1985, when a glacial lake burst sending a 15-meter high wall of water down the mountains, drowning people and destroying houses. And today we can see on TV, that Netherlands in Europe or Florida in the USA get a flood disasters.
However, it will make hurricanes and other storms more destructive and the higher temeratures may also make these storms more intense and frequent. And a big problem is the volcanic eruptions which pollute the air rapidly.
Although much remains to be learn about global warming, many organizations applicate cutting greenhouse gas emissions to reduce the impact of global warming.
Consumers can help slow global warming by:
-Walking, riding your bicycle, or taking the bus instead of always going by car.
-Not wasting electricity (turn off the lights, the radio, the TV and the computer when you're not using them).
-Reducing, reusing or recycling all kinds of items, from soda pop cans to clothes, to save energy and raw materials.
-Planting trees to help absorb excess CO2, and to provide shade and windbreaks to keep buildings at more even temperatures so they will require less energy for heating or cooling.
