The phenomenon of climate change is as old as the planet earth itself. For ages, the temperature at the surface of the earth has varied, triggering many different climatic eras: Earth has hitherto known five ice ages, and the first of them is estimated to have happened around 2.4 to 2.1 billion years ago. However, the scientific community proved that mankind has now to face an unprecedented acceleration of such change. What is called in the public opinion "global warming" is the manifestation of such acceleration. The consequences are so far dramatic, and the examples numerous, the melt of the icecap being the most obvious. Finally, a consensus about the explanation of such change has been reached, albeit many skeptical theories also exist.
This is to be correlated with the technological explosion known by mankind during the 20th century, especially through a blossoming industrialization. Thanks to such progresses, the world is now globalized. However, such development was not uniform; some countries are still trying to catch up on the developed countries of the northern hemisphere. They are trying to improve their level of development as the developed world did earlier.

It was very impressive. Then, we went to Times Square. It's the place where there are big adverts on giant screens. How wonderful! [...]

I think I drank about 5 liters of it. On Thursday, we went to the Metropolitan Museum of Art. It was very good, but the museum is too big, so we couldn't visit the entire museum. The day after, we visited Princeton University. [...]
[...] Sample letter to a friend C/O Mr. and Mrs. AGARWAL Xxxxxxxxx xxxxxxxx Mr. Antonio PASTA xxxxxxxxxxx FRANCE Saturday, 16th Hey Antonio, I'm in the USA, in Edison, New Jersey. It's not very far from NYC. I really enjoy my trip. It was my first time traveling oversea; and I really enjoy it. The flight was long, but not too boring because I was with two of my friends.
