Causes Of The Greenhouse Effect. Trace gases in the atmosphere cause the greenhouse effect by acting like a blanket on a global scale and slowing the radiation of heat back out into space.mpacts of Different Greenhouse Gases. Carbon dioxide is the largest contributor to global warming, and occurs in relatively high concentrations. On the other hand, methane occurs in low concentrations, but it has a much higher heat-trapping capacity than carbon dioxide per unit volume.
Behind the struggle to address global warming and climate change lies the increase in greenhouse gases in our atmosphere. A greenhouse gas is any gaseous compound in the atmosphere that is capable of absorbing infrared radiation, thereby trapping and holding heat in the atmosphere.By increasing the heat in the atmosphere, greenhouse gases are responsible for the greenhouse effect, which ultimately leads to global warming.he gases in the atmosphere that absorb radiation are known as greenhouse gases (sometimes abbreviated as GHG) because they are largely responsible for the greenhouse effect. The greenhouse effect, in turn, is one of the leading causes of global warming.
