30 years ago climate scientists warned us to expect an imminent ice age....it even made the cover of Time, if I'm not mistaken.
I noticed that you didn't dispute the fact that the dominant greenhouse gas is water vapor. This is not a disputable fact; no climate scientist will argue with you there. Global warming is also not a disputable fact; it is well-documented and has been occuring since records were first kept. However, saying that scientists have reached an "unprecedented consensus" is absolutely false; and would that even matter? How often do you read a story on CNN or MSNBC that begins with the phrase "Scientists NOW think...." Science is in its very nature an evolutionary process, and findings change over time. Who remembers when nine of out ten doctors smoked Camels more than any other cigarette?
I'm ranting now, sorry. The point is that I've never heard a satisfactory answer as to why water vapor isn't taken into effect when discussing global warming, when it is undeniably the largest factor of the greenhouse effect. But according to the Department of Energy and the EPA, C02 is the dominant greenhouse gas, accounting for over 99% of the greenhouse effect....aside from water vapor. This certainly makes C02 the most significant non-water contributor to global warming...but even then, climate scientists will not argue with you if you point out that nature produces three times the CO2 that humans do.
Forty years ago, cars released nearly 100 times more C02 than they do today, industry polluted the atmosphere while being completely unchecked, and deforestation went untamed. Thanks to grassroots movement in the 60s and 70s (and yes, Greenpeace), worldwide pollution has been cut dramatically, and C02 pollution has been cut even more thanks to the Kyoto Agreement. But global warming continues, despite human's dramatically decreased pollution of the atmosphere.
No climate scientist will argue the fact that global climate change has, in the past, universally been the result of cyclical variances in Earth's orbit/rotation, and to a lesser degree variances in our Sun's output. Why then, since pollution has been reduced dramatically, and since climate change is known to be caused by factors outside of our control, is it so crazy to believe that we're not at fault anymore?
And since when does being in a "tiny percentage" denote right/wrong? Aren't you a Mac zealot?
