N2o, cfcs, synthetic fluoride components (sf6: brief history, svante arrhenius (1896) of sweden, was the first to theorize the impact of co2 on earth"s climate (not taken seriously until 1950s, 1980. Infrared radiation (700 nm-3,500 nm: 1800 nm is significantly absorbed by ghgs, sources of earth"s energy, sun contributes energy to earth, about 30% of the sun"s energy is reflected directly back into space. The rest (70%) of the sun"s energy is absorbed into the earth"s system: effects of ghg on warmer earth, carbon cycle and global warming, carbon traps in our earth, fate of co2 and methane. Interfering carbon balance: certain human activities release carbon into the atmosphere as carbon dioxide (co ) and methane (ch ).
