Last Wednesday COTTonLINE wrote about a NASA animated map that shows CO2 production over the period of a year. Notable was the much greater volume of winter-time production, probably associated with fires to keep warm.
This suggests global warming could be somewhat self-limiting. That is, as the northern hemisphere becomes warmer in winter, people will burn less fuel staying warm and production of CO2 will decline.
Perhaps Gaia will outsmart us once again.
