Detailed explanation-1: -A vital component of the atmosphere, carbon dioxide (CO2) is released through natural processes (like volcanic eruptions) and through human activities, such as burning fossil fuels and deforestation.
Detailed explanation-2: -Carbon dioxide (CO2). Accounts for around three-quarters of the warming impact of current human greenhouse-gas emissions. The key source of CO2 is the burning of fossil fuels such as coal, oil and gas, though deforestation is also a very significant contributor. Methane (CH4).
Detailed explanation-3: -Burning fossil fuels, releasing chemicals into the atmosphere, reducing the amount of forest cover, and the rapid expansion of farming, development, and industrial activities are releasing carbon dioxide into the atmosphere and changing the balance of the climate system.
Detailed explanation-4: -Direct emissions are produced by burning fuel for power or heat, through chemical reactions, and from leaks from industrial processes or equipment. Most direct emissions come from the consumption of fossil fuels for energy.
Detailed explanation-5: -Carbon dioxide from the burning of fossil fuels is the largest single source of greenhouse gas emissions from human activities.
