Task: Question Answering
Input (English): Background Paragraph: Current Situation : Currently the heating effect of extra greenhouse gases (since the start of the industrial revolution) is equal to about . Thus the recent period has recorded parallel increases in concentration of carbon dioxide and average global temperature. As more greenhouse gases are put into the atmosphere the temperature will increase further. There are certain effects of a warmer Earth (discussed more in optional section), which could accelerate the process, even if no more greenhouse gases are put into the atmosphere (an unlikely prospect for the foreseeable future). 
Story: Moon and Earth were two sister planets, both inhabited by humans. People of Earth released large quantities of greenhouse gases into the atmosphere over the last decades, while Moon people were taking good care of their planet and the environment. 
Question: Which planet didn't record parallel increases in concentration of carbon dioxide and average global temperature?
Output (English): Moon.
