increase in carbon dioxide

Carbon dioxide is a major greenhouse gas; higher atmospheric CO2 from burning fossil fuels and deforestation increases the greenhouse effect and raises global temperatures. (The other choices—decreases of nitrous oxide or methane would reduce warming; cloud changes are more complex and not simply an increase = warming.)
