There is consensus on how we would know what progress we’re making: We can measure the concentration of greenhouse gases in the atmosphere. It currently stands at 385 parts per million of carbon dioxide equivalent; the NASA team led by James Hansen now says that to get back to the range of atmospheric conditions under which human civilization rose and flourished, we need to push it back to 350 ppm. That may take 30 years, but it’s doable (if we start now we can reverse the trend before reaching the irreversible 450 level). In the meantime, glaciers and ice caps continue to melt and a meter (or more) of sea level rise is probably unavoidable.

Everytime I read a Global Climate Change post, regardless of it leanings, I am stuck by this overwhelming notion that there are people who actually believe man can stop Global Climate Change. Even if we had the intellectual and physical capacity to do so, there would remain a nagging question: How would we know when we’ve actually stopped the change? I ask this question alot and rarely get a rationale answer. A rational way to address the question might be along the lines of the position of John A. Warden III in his Thinking Strategically About Global Climate Change . There is no doubt that achieving any sort of global consensus on an ideal climate would be difficult, but it might be useful to try!
