Carbs are more like lines of carbon with hydrogen and oxygen sticking out while lipids are connected by an school glycerol I think. usually a triglyceride. and some have some for hydrogen(unsaturated) while other are full to the max(saturated) this determines weather it's canola oil or butter. I hope that helped?
Global warming is the unusually rapid increase in Earth's average surface temperature over the past century primarily due to the greenhouse gases released by people burning fossil fuels.
