Are climatic changes around the world human-made?

I think global warming is real, and as a result of the activities of humans on earth. Just look at the follow facts: 1. Temperature records go back to the late 19th Century and show that the global average temperature increased by about 0.6C in the 20th Century. 2. Sea levels have risen 10-20cm - thought to be caused mainly by the expansion of warming oceans. 3. Most glaciers in temperate regions of the world and along the Antarctic Peninsula are in retreat; and records show Arctic sea-ice has thinned by 40% in recent decades in summer and autumn. On the other hand, there are anomalies however - parts of the Antarctic appear to be getting colder, and there are discrepancies between trends in surface temperatures and those in the troposphere (the lower portion of the atmosphere). Still, I believe we have to reduce or even reverse global warming, for the future is unsure, and it would be catastophic to realise too late that in fact "global warming" was the cause of all of this.

Many people around the world nowadays is talking about the global warming problem, in my oppinion its a serious problem so we must to do something from now, in the other hand i also think that maybe televisions and newspapers are giving too importance in order to be concerned us, have a nice day on mylot and happy earnings also.

All the worlds scientists agree with you.
