Explanation:

Combustibles (fuels) when burned release greenhouse gases like carbon dioxide. Excessive use of fuels leads to more greenhouse gas emissions, which trap heat in the atmosphere, causing global warming (calentamiento global) to increase. The first option is incorrect as more fuel use would not decrease global warming.

Answer:

B. aumentará el calentamiento global (Note: Assuming the options are labeled, if original had labels like A and B, with A being "disminuirá el calentamiento global" and B being "aumentará el calentamiento global", the correct one is the second option, so formatted as above. If no labels, just the text "aumentará el calentamiento global" is the correct choice.)
