Question

greenhouse gas
defining key terms
what term is used to describe the ability of a molecule to
contribute to global warming over a period of time?
greenhouse warming potential
carbon footprint
molecule flower profile

Explanation:

The text explicitly defines "greenhouse warming potential" as the term for a molecule's ability to contribute to global warming over time. "Carbon footprint" refers to the total amount of greenhouse gases (including carbon dioxide and methane) that are generated by an individual, event, organization, service, or product, expressed as carbon dioxide equivalent. "Molecule flow profile" is not a relevant term in this context.

Answer:

greenhouse warming potential
