Detailed explanation-1: -Five key greenhouse gases are carbon dioxide, nitrous oxide, methane, chlorofluorocarbons, and water vapor. While the Sun has played a role in past climate changes, the evidence shows the current warming cannot be explained by the Sun.
Detailed explanation-2: -Nitrous oxide enhances the greenhouse effect just as carbon dioxide does by capturing reradiated infrared radiation from the Earth’s surface and subsequently warming the troposphere (lower atmosphere).
Detailed explanation-3: -CO2 stays in the atmosphere for up to 1, 000 years, methane for around a decade, and nitrous oxide for approximately 120 years. Measured over a 20-year period, methane is 80 times more potent than CO2 in causing global warming, while nitrous oxide is 280 times more potent.
Detailed explanation-4: -The single-most important thing that we can do to combat climate change is to drastically reduce our consumption of fossil fuels.
