The earth is warming... What else can we confirm...?
So can we now agree not only that the earth is warming, but that it is following a curve previously accepted by most climate scientists, and used as the basis for study into causes for quite a few years now?
If so, then we can pretty much reject your vague assertions and conclusions...
Yes, there is a CO2 cycle, but this doesn't mean that it is stable or free of trends. We know that we have added CO2 to the atmosphere faster than this has ever happened before. This is well-documented and not subject to debate. It is possible and maybe even likely that processes exist or will develop that will counteract this over time, but in the meantime (at least in our lifetimes and those of our children and grandchildren) the increased levels of CO2 are trapping heat coming into the atmosphere faster than it can leave, and the oceans are acidifying. This is having an effect on weather systems and ecosystems, and sea levels are rising.
So, in response to your questions, yes, yes and yes. Your counter-arguments display a lack of understanding of the processes involved.
