Yes and no.
Human activities do not meaningfully enter the equation.
And global warming per se is not happening in any significant fashion at the moment. When it does, just as in the past, it will not likely be due to human activities and it won't be amenable to human intervention (keening by the vested interests qua Jeremiahs on the left and right notwithstanding). Gaia alone is the operant entity in maintaining homeostasis.
