yeah but on this I tend to to believe them .. cant believe human activity is not having an impact

95% of the "greenhouse gas" is water vapor. Of the remaining 5% only a small portion of it is caused by humans. So, I would agree that human activity has an impact - roughly the same impact that I had on the world economy this morning when I bought a cup of coffee and a chocolate bar.

Jaysun, I do not agree with your reasoning here.

Percentages of substances are arbitrary when you consider the impact of each substance.

Would you be worried if 5% of that insignificant coffee was composed of Anthrax???
