+==== Experiments at 70 km ====
+^At 70 km, there is a spike in the CO<sub>2</sub> from emission from the warm upper stratosphere.^
+|{{ :300ppm20km300ppm70kmf.png }}|
+^ Double CO<sub>2</sub>. Enhanced stratospheric cooling.^
+{{ :300ppm70km600ppm70kmf.png }}
+^Smaller temperature increase is needed to restore equilibrium. Increasing stratospheric temperature is not a good approximation for what happens in restored equilibrium. The stratopsphere would cool. ^
