Environmentalists are especially concerned about the amount of carbon dioxide released from burning coal because it is a significant greenhouse gas.
A greenhouse gas (GHG or GhG) is a gas that produces the greenhouse effect by absorbing and emitting heat infrared radiation. Water vapor (H2O), carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and ozone are the planet's main greenhouse gases (O3).
Without greenhouse gases, the average surface temperature of the Earth would be closer to 18 °C (0 °F) than it is today, which is 15 °C (59 °F). Additionally, greenhouse gases are found in the atmospheres of Venus, Mars, and Titan.
Since the start of the Industrial Revolution (about 1750), human activities have increased atmospheric carbon dioxide content by over 50%, from 280 ppm in 1750 to 419 ppm in 2021.
