The cell membrane and the associated transport proteins found in the membrane are responsible for regulating the movement of hundreds, if not thousands, of different types of molecules into and out of the cell.
Among the gases emitted when fossil fuels are burned, one of the most significant is carbon dioxide, a gas that traps heat in the earth's atmosphere. Over the last 150 years, burning fossil fuels has resulted in more than a 25 percent increase in the amount of carbon dioxide in our atmosphere.
Specifically the emission of Carbon dioxide, methane  and several other greenhouse gases.   A:  The CO2 from burning fossil fuels is one of the causes of global  warming, but ironically, the solid particles (soot) which also  comes from fossil fuels is filtering out sunlight and having a  cooling effect.
