Answer 1

Carbon

Step-by-step explanation:

Global warming is currently a great concern to the world. It is the process whereby the temperature of the atmosphere rises due to the effect of certain gases called GREENHOUSE GASES. Greenhouse gases are those gases that have the ability to trap and emit heat into the atmosphere e.g carbon dioxide, methane, CFC etc.

Carbon dioxide and methane, for example, are greenhouse gases that contain CARBON element in their structure. This implies that an increased input to the CARBON cycle may be responsible for global warming because more carbon input produces more carbon-based greenhouse gases, utterly leading to global warming.
