Step-by-step explanation:
The subject of this question is Science and the grade level is High School.
The increase in carbon dioxide and other greenhouse gases in the atmosphere amplifies the natural greenhouse effect. This phenomenon causes the temperature of the Earth's atmosphere, ocean, and land surface to rise. Gases like carbon dioxide, methane, and nitrous oxide trap the sun's heat, creating a greenhouse effect that warms the planet. The increasing emissions of greenhouse gases, primarily from the burning of fossil fuels, have intensified this effect, leading to global warming.
