Detailed explanation-1: -The CO2 released from the burning of fossil fuels is accumulating as an insulating blanket around the Earth, trapping more of the Sun’s heat in our atmosphere. Actions carried out by humans are called anthropogenic actions; the anthropogenic release of CO2 contributes to the current enhanced greenhouse effect [1] .
Detailed explanation-2: -An increase in the atmospheric concentrations of greenhouse gases produces a positive climate forcing, or warming effect. From 1990 to 2019, the total warming effect from greenhouse gases added by humans to the Earth’s atmosphere increased by 45 percent.
Detailed explanation-3: -The infrared radiation strikes a molecule such as carbon dioxide and causes the bonds to bend and vibrate-this is called the absorption of IR energy. The molecule gains kinetic energy by this absorption of IR radiation.
Detailed explanation-4: -Continental drift. The ice-albedo feedback is a process that can increase the rate of greenhouse gas emissions into the atmosphere in response to a decrease in albedo. When the Earth’s surface is covered in ice, the amount of sunlight that is reflected back into space is decreased.
Detailed explanation-5: -Molecules of carbon dioxide (CO2) can absorb energy from infrared (IR) radiation. This animation shows a molecule of CO2 absorbing an incoming infrared photon (yellow arrows). The energy from the photon causes the CO2 molecule to vibrate.
