Detailed explanation-1: -Carbon dioxide in the atmosphere warms the planet, causing climate change. Human activities have raised the atmosphere’s carbon dioxide content by 50% in less than 200 years.

Detailed explanation-2: -Molecules of carbon dioxide gas have a tendency to absorb the heat. The carbon dioxide molecules present in the atmosphere absorb this heat energy. Hence, an increase in the amount of carbon dioxide molecules in the atmosphere also increases the heat energy, which increases the temperature of the Earth.

Detailed explanation-3: -Carbon dioxide is the greenhouse gas that is most emitted through human activity, accounting for around 75% of human-caused emissions. The burning of fossil fuels, including natural gas, is the primary cause of CO2 emissions.

Detailed explanation-4: -CO2 accounts for about 76 percent of total greenhouse gas emissions. Methane, primarily from agriculture, contributes 16 percent of greenhouse gas emissions and nitrous oxide, mostly from industry and agriculture, contributes 6 percent to global emissions.
