GW temperature lag? So, temperature increases precede co2 increases by as much as 800 years, and co2 fuels these temperature increases via the greenhouse effect. Why doesn%26#039;t this %26quot;feedback loop%26quot; keep going out of control? In other words, what is the catalyst that brings temperature down? Also, why does co2 keep going up after temperature has already started going down again? Also, if it really is a %26quot;feedback loop%26quot;, then why are the slopes of temperature and co2 identical? 75% 3 Votes 0% 0 Votes 25% 1 Vote
