(Vortrag zur globalen Erwärmung auf Englisch in Stichpunkten, report about global warming in english)
->At the beginning: want to give out some caricatures 2 YOU for taxing your brains…
-Global warming describes the current increase of the global average-temperature.
-The name was shaped between the 80ies and 90ies and refers to anthropogenic changes of the global climate.
-> (in this case anthropogenic means changes which are "caused by human")
-These changes consist not only in the increase of the average-temperature of planet Earth, ___
but they are accompanied by a multiplicity of regional and local phenomenons.
-Most Scientists say, there are 3 principal causes for global warming.
-The first reason is the increased solar-activity. (!)
-More often, the sun radiates more intensive and more dangerous radiations to our planet from year to year.
-Furthermore natural emissions are the second reason. (!)
-That includes volcanic eruptions, forest-fires and other emission producing sources.
-> Through these processes many carbon dioxides and other toxic gases released and soar up to the atmosphere.
-The last and by far most important cause is the anthropogenic greenhouse effect. (die Zahlen entsprechen gemalten BIldern an der tafel..ist ja easy)
-> It works in the following way:
-People burn toxic waste and fossil fuels,
they use the car at every opportunity and
they produce generally much emissions like carbon dioxide and CFC (chlorofluorocarbon). (1)
-The outcome of this process is that the emissions, mostly carbon dioxide, soar up and build an own layer in the atmosphere. (2)
-If the solar radiation (3) touch the earth now, it will be reflected (4),
but can't get out of the atmosphere because the "emission-layer" prevent that natural expiry (5).
-And that is why solar radiation comes back, stays on earth and heats up the atmosphere so that we have a global warming all over the world..(6)
In addition to that I have a nice diagram. (!)
-It shows that the global average-temperature has raised in the last 140 years about approximately 1 degree Celsius.
-Moreover does it prove that the temperature dramatically rise and becomes higher from year to year.
-Furthermore scientists are of the opinion that the global average-temperature rises up to 5 degrees until 2050.
All the mentioned reasons create the so-called effect of "global warming". (Mitte!)
-The consequences of global warming are extensive and disastrous.
-One of the worst results is the displacement of the climate and vegetation-zones.
-> The outcome of this is that the balance of nature will be disturbed and a lot of species become extinct.
-Another result of global warming is the melting of the polar ice caps and glaciers.
-> So on the one hand the sea level rises, which entails more floods and the elimination of some islands.
-> And on the other hand warm streams, like the gulf-stream, get colder, and so some countries get colder too (like europe in this case)!
-Besides another consequence is that the weather will playing mad.
->That means we have heavier rainfalls and winds, but also more heat waves and hurricans.
-Last but not least I want to mention some other results in a note form:
->for example the agriculture will have a bad harvest,
->then the deserts become bigger
->besides less snow falls down
->and finally the solar acitivity favors skin cancer.
-In the end of my report I want to present some ways how we could get out of that vicious circle:
-> First we can save energy by using renewable energy,
-> by using public transport
-> and by turning off the heaters on night.
-> In addition to that we should buy environment friendly products and biodegradable materials.
-For summing up and making the point
we can notice that global warming is an self-inflicted effect by the human race
and if we do nothing against it, we will get assimilate...
