Our friend and MR author Christian Parenti misunderstood our brief comments ("Notes from the Editors," MR, November 2013) on his article in the summer issue of Dissent. We did not challenge the science of climate change, which tells us that carbon emissions must cease before one trillion metric tons of carbon have been emitted—a tipping point that will be reached in about 2040 under business as usual. There is no question that the fossil-fuel industry must go. In fact the reality that the world is confronted by a planetary emergency with respect to climate change (and the global ecological problem as a whole) and that the critical threshold will likely be approached by around 2040 (or even sooner) under capitalist economics as usual, is one that has been insisted upon by Monthly Review for twenty years.
