I said I wouldn't debate the issue, and I still won't, but while observing the thread I noticed that while everyone is debating whether the current round of global warming has a major human-caused component or not, no-one seems to be concerned about the possibility of a runaway greenhouse effect in it's beginning stages- REGARDLESS what percentage the sun, or humans, or any other component may have. There is little argument on any side that the earth's carbon sinks are at or near capacity- in fact deforestation in developing tropical countries has reached a critical level- not to mention that as ocean temperatures rise- REGARDLESS of cause, the solubility of carbon dioxide in them decreases. Atmospheric CO2 levels have risen, indisputably. Until such time as we know for sure that we won't have an unlivable environment in a few hundred or thousand years, COMMON SENSE dictates that we as a species need to reduce our production of greenhouse gasses (and all pollutants, really) and conserve resources. After all, the fossil fuel industry does have a limited lifetime. One day there simply won't be anymore available sources (for a long, long, time, at least!). The hydrogen ecconomy (or something better) is inevitable, assuming we don't suffocate ourselves first. Again, I'm not debating whether human influences are a major component of global warming. I think those who passionately debate that issue are merely trying to defend an ecconomic investment (or political- they really are the same thing in this country, and most other representative governments), regardless of which side you're on. Note that both sides are constantly trying to accuse the other of being motivated by money- whether or not that's true, it's plain to me that good old fashioned hubris is behind the argument on both sides as well. Come on, people, put the pride aside and quite picking nits. It's time to reduce emissions and spend a LOT more money on new technologies, new fuels, and greenhouse effect research. *The debate on the size of a human component is stupid*. Even if it's miniscule, it needs to be reversed.
