Hi,
I had to work on the topic ''climate change as a natural process'' and I found some interesting statements. The expert's arguments are based on the fact that the world has experienced cold and warm periods throughout. They say if you look at the last million years there were always big changes relatet to temperature and precipitation (niederschlag). Furthermore it is explained that there have been times, in which the climate changed more than nowadays in a certain period of time. Some rasons for natural climate change are for example changes in ocean currents or large erruptions of volcanoes.
Moreover the green house effect is often mentioned as an important cause, but many experts are saying that this effect is a nessescary condition for the multifacedet development of life on the world.
I think due to all these aspects it is very difficult to decide how far the humans are blamed for the actual climate changing. That climate is changing over years is deffinately natural, but I could image that the rising emission of CO2 speeds up this development. But human beeing haven't such a big influence on something that big like the world's balnce, like the media is reporting all the time. They exaggerate in many points.

Obama

                           Obamas climate policy
 
 Obama has set high expectations concerning climate changing:
By 2050 he wants to reduce gas emissions 80 percent and he is willing to invest 150 billion dollars in order to reach this aim. Another topic is fighting unemployment by creating new
“green jobs”. As there are several millions of unemployed people in the USA, he intends to kill two birds with one stone: first, he gives work to jobless people and second, he changes the environmental consciousness by establishing renewable and “clean” energy.
Welcome side effect: using domestic energy sources means getting independent from big oil producers like the Middle East.
Moreover, he wants to field hybrid cars and thus abate carbon dioxide emissions as well as he wants to propose a National Low Carbon Fuel Standard, which will regulate the car’s emissions by law.

climate change is a human-made process ?!?

Anthropogenic factors are human activities that change the environment. In some cases the chain of causality of human influence on the climate is direct and unambiguous (for example, the effects of irrigation on local humidity), whilst in other instances it is less clear. Various hypotheses for human-induced climate change have been argued for many years though, generally, the scientific debate has moved on from scepticism to a scientific consensus on climate change that human activity is the probable cause for the rapid changes in world climate in the past several decades. Consequently, the debate has largely shifted onto ways to reduce further human impact and to find ways to adapt to change that has already occurred.

I have the same opinion like many experts and think, that the climate change is a human-made process. Many facts which are mentioned in the text argue for this perception. So it is really important that everyone tries to protect the environment. If we do not change something soon we will have much bigger problems then finding alternative energy and wars.

the climate policy of Obama

Obamas climate policy
Obama wants to reduce the greenhouse gas emission “80 percent below 1990 levels by 2050” therefore he wants to invest about 150 billion Dollars during the next decade.

  • By enlarging clean energy generation he wants to create millions of new “Green Jobs” for the American people.
  • Moreover the clean energy generation shall lead to the independence of the big foreign oil producers. (Middle East & Venezuela)
  • The energy won by coal shall also be reduced and a new National Low Carbon Fuel Standard shall be established
  • Renewable energy and fuel will be developed.
  • Furthermore he wants to strengthen the relationship towards other countries to stop climate change.
  • Innovate car technology
