Methane emissions have a feedback on its own lifetime, serve as an ozone precursor, and reduce the production of sulphate and nitrate aerosols (and consequently indirect cloud-aerosol effects), all of which amplify its net warming effect to about 1.2 ppm, a factor of more than 200 smaller).

Our ozone layer serves as a lifesaving UV barrier for planet earth, functioning to absorb most of the sun’s ultraviolet radiation. At the same time, ground-level ozone pollution is extremely harmful to human health. Good Ozone’: Our Essential Sun Shield. How is Ozone Created?

Recent science doesn’t support this optimism, as new studies show that the increased release of Black Carbon, one of the most potent climate change forcers—as well as soot, carbon dioxide, methane and ozone from more traffic in the Arctic—could lead to a 20% increase in the global heating that is causing warmer ocean temperatures.

The sun receives a constant stream of energy produced by nuclear processes that generate an immense amount of heat, light, and radiation. This radiation hits the atmosphere and is absorbed by the ozone layer which reduces the most harmful. At the center of our solar system is a star that we call “The Sun”. Deforestation.
