Detailed explanation-1: -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-2: -Burning fossil fuels, cutting down forests and farming livestock are increasingly influencing the climate and the earth’s temperature. This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming.
Detailed explanation-3: -The higher concentrations of greenhouse gases-and carbon dioxide in particular-is causing extra heat to be trapped and global temperatures to rise.
Detailed explanation-4: -Carbon dioxide is the primary greenhouse gas contributing to recent climate change. Carbon dioxide enters the atmosphere through burning fossil fuels, solid waste, trees, and other biological materials, and as a result of certain chemical reactions, such as cement manufacturing.
