How sad...
All the conversation about warming or cooling sadly diverts attention from the real issue: we are not living a sustainable lifestyle, regardless of what it does or does not do to the environment.
That we can exist at all is only because one natural process uses the waste of another in a circular way. As time goes on, one process figures out how to use the waste of another. And eventually that evolution of things made us into what we are. If all outputs can be consumed by some other process in approximately the same timeframes, then everything chugs along just fine.
But that is not happening at the moment and will not in the foreseeable future if we don't change how we live. The evidence? The rate at which CO2 and other gasses are accumulating in the atmosphere indicates that no current natural process can use them as fast as we produce them. Yes, all those gasses naturally occur (like the cows mentioned above), but not at the extremely high levels we produce. Unless something finds a way to digest it soon, it will either accumulate beyond our ability to tolerate the effects, whatever they may wind up being, or be corrected by a sudden, massive upheaval (like an ice age or something that big). This happens in all cycles: physics, biology, economy, weather - nothing is exempt from this basic principle.
