Final answer:
Anthropogenic greenhouse gases are gases released into the atmosphere as a result of human activities, contributing to global warming and climate change.
Step-by-step explanation:
Anthropogenic greenhouse gases refer to the greenhouse gases that are emitted into the atmosphere as a result of human activities. These gases are not naturally occurring and are largely responsible for global warming and climate change. The main anthropogenic greenhouse gases include carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).
