Carbon dioxide is no more the only one

Carbon dioxide is not the guilty one alone for climate changes.
It has two brothers helping: Methane and Nitrogen Trifluoride.
One comes from ancient plants, the other from flat-panel screen technology.
For now their action is nothing compared to the one produced by the burning of coal, oil and other fossil fuels, but is rising.
Methane produces one third of warming effects of Carbone dioxide and comes from coal mining, animal waste and decaying plants.
The methane produced thousands of years ago by decaying Arctic plants was frozen and trapped in the Ocean, but now, with the warming of the Artic, it will defrost and harm the environment.

Nitrogen Trifluoride levels have quadrupled in the last decade. For now it contributes only 0.04% of the global warming effect, but is thousands of times stronger at trapping heat than carbon dioxide.
So, an increase of Nitrogen Trifluoride levels would certainly cause big harm with the warming of the climate.
