(photosynthesis and such). 9. The gases that cause the 23 W/m2 (14% by RHT) transferred by RHT. a. 79% Caused by water vapor. b. 14% Caused by carbon dioxide. c. 1% Caused by ozone/oxygen. d. 1% Caused by all other greenhouse gases. 10. The total GHE is caused only by energy that is transferred to the atmosphere. This is because temperature changes only when energy is transferred. 11. Carbon dioxide accounts for only 2.8% of the total GHE.
