While researching a topic, a student has taken the following notes:
<ul> <li>The greenhouse effect refers to atmospheric warming due to certain gases.</li> <li>These gases (CO2, methane, water vapor) trap outgoing infrared radiation.</li> <li>Without it, Earth's surface would be far colder.</li> <li>Human activities have intensified the effect since the Industrial Revolution.</li> <li>The intensified effect is a major driver of modern climate change.</li> </ul> The student wants to summarize the greenhouse effect for an audience unfamiliar with the topic.
