In the long run, warming will be determined by how much carbon we pump into the atmosphere before we stop. If we can shave down the curve even a little, we reduce the ultimate tonnage of carbon lingering in the atmosphere. The answer is unequivocally “yes.”. In terms of emissions cuts, the basic rule is simple: Every ton counts.
