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.
First, when fossil fuels (coal, oil, natural gas) are burned, the carbon in them combines with oxygen in the air to form CO2 (carbon dioxide). CO2 absorbs heat being radiated off the Earth that would normally escape into space, warming the atmosphere. Thus, burning fossil fuels cause global warming, resulting in climate change.
