same old question.. is global warming really happening?? if yes, are humans solely responsible for this? i have read some books that say that, as earth had "Ice age"(without any human interference) then, its having a "hot age" now. the book also says that human interference with environment in broader sense is very 'little'. although the book agrees that pollution to local surrounding is definetely happening, it still refuses that human activity alone is responsible for such a Major effect as "Global Warming". wats ur opinion?

Funny thing i posted a topic with almost exacly the similar title :P Anyways It is really happening, It is part of the earth's 'cycle' And therefore ice ages happen alot (in the past) Anyways another thing is that if you've watched the global warming documentary with Al Gore. You will really understand whats going on. Another thing is that pollution and such have been reduced badly since the 1970s, But it is still happening i am estimating (or heard) that global warming will happen in around 40-60 years... :S

Its true that the world is warming naturally, in the 15th - 17th century we had what is known as a mini Ice age where temperatures were significantly lower than today and glaciers were much more extensive. Since then the temperature around the world has been gradually rising, generally between 0.2 and 0.5 oC per 100 years. However since the industrial revolution this rate has significantly increased, temperatures rose by about 1.5oC in the last 100 years and all evidence shows that this rate of rise is increasing significantly, by as much as a 4oC rise in the next 50 years. Scientific evidence shows a direct link between greenhouse gas emission (Carbon dioxide etc.)and this significant increase in the rate of warming. So although it is true that even if we weren't here the global temperature would be rising, it would not rise by anywhere near the rate it is anticipated to over the next 50 to 100 years

Yes it is happening, that is beyond doubt, I in my still short lifetime have seen rather grand differences in when winter starts and stops, that would be way too fast for any natural phnomenon, but still that may ver well be part of the answer.
