GLOBAL WARMING

Hello this is my first article and i think that you like it. I am going to tell about global warming. the mayority of the information of this article is taken from wikipedia. 

Global warming is the observed century-scale rise in the average temperature of Earth's climate sistem. Since 1971, 90% of the increased energy has been stored in the oceans, mostly in the 0 to 700m region. Despite the oceans' dominant role in energy storage, the term "global warming" is also used to refer to increases in average temperature of the air and sea at Earth's surface.

Since the early 20th century, the global air and sea surface temperature has increased about 0.8 °C, with about two-thirds of the increase occurring since 1980. Each of the last three decades has been successively warmer at the Earth's surface than any preceding decade since 1850.
