Sentences with phrase «greenhouse warming resulting»

While carbon dioxide is the main greenhouse gas resulting from human activity, it's not the only thing causing the atmosphere to warm.

Global warming is the result of a greenhouse gas - caused imbalance between incoming solar energy and heat that the Earth radiates away to space.
If we accept that greenhouse gases are warming the planet, the next concept that needs to be grasped is that it takes time, and we have not yet seen the full rise in temperature that will occur as a result of the CO2 we have already emitted.
