I have searched and searched for information about the effect of human breathing on global warming and in every case, the article goes immediately into talking about how much CO2 is contained in the human breath and how the CO2 can contribute to global warming.
Enough about the CO2. Greenhouse gases do help keep the heat in but what about the obvious contribution to global warming from humans– THE HEAT?
Think about the last time you were in a room with a bunch of people and the windows were closed. Perhaps it was in a classroom, perhaps you were at an orgy. In most cases, after a period of time, the room heated up. Was this caused by the CO2 buildup? No! It was caused by the HEAT given off from breathing and body heat loss.
On a cold day, when you breathe you can see your breath? Why? Because the water vapor in your breath is warmer than the air and it condenses when hit with the cold and you see it. The fact of the matter is that it’s not just the water vapor in your breath that has been heated — the air is heated too. If you’re inhaling 30 degree air, and exhaling air that’s warmer than that, haven’t you contributed to an increase of the ambient temperature, however minor it is?
So why is the obvious fact that the human body gives off heat via breathing, sweating, and emanating being ignored and everyone jumps to CO2 analysis?
If you think about the atmosphere as a giant room, filled with billions of people, is it so far fetched to think that the more people you add to the “room” will result in a warmer temperature overall?
