I largely agree. But I am open to the fact that I don't know for sure. None of us really do. And when you see money/power get injected as an influencing agent into something like this, it really makes me question, even harder, the validity of it. I don't think it's unreasonable to assume that we are affecting our planet or even the temperature of it. But how much? I don't think it is possible to say for sure. Certainly, when someone assures you that they absolutely know without a shadow of a doubt the answer to that question, I immediately become skeptical. I don't even know if it's POSSIBLE to know. That doesn't mean we shouldn't do better. But dire predictions of the world ending and of great calamity have been around forever. We're still here. All that said, we should still do our best to reduce reliance on fossil fuels, manage waste better, and all pitch in to make our environment a better place than it currently is.
For me its simple, the Earth has a natural cycle to control CO2.....there is variability in this system like any other natural system.....things like ocean currents, continent placement, where we are in one of the numerous orbit cycles etc....this stuff all factors in and we don't have a good idea of how it all works.....but without a doubt man taking 35 BILLION metric tons of sequestered CO2 annually and releasing it into that system is upsetting the balance there is no way it isn't. There is IMO no denying the sudden recent spike in CO2 PPM levels are a direct result of this....how much warming this is causing I don't know but I know there is no way it isn't having a impact.
