Water vapor is H2O. Tell me, where in there is the Carbon located? I see the hydrogen. I see the oxygen. I fail to see any carbon. So tell me, since you're the chemistry genius. Where's the carbon in water vapor?
“Carbon” (chemical symbol C) is what we burn to get energy in society.
"Carbon" is also stored in the oceans as dissolved atmospheric carbon dioxide (CO2) and as calcium carbonate shells in marine organisms.
Carbon moves from the atmosphere to the biosphere chiefly by the process of photosynthesis and as every grade schooler learns, CO2 enables photosynthesis and plant growth: carbon dioxide and water in, oxygen and plant growth out, through complex chemical reactions.
Without CO2, there would be no plants and no oxygen; life as we know it would cease. Carbon dioxide is truly the “gas of life” – and no attempt by Al Gore, James Hansen or EPA to brand it as a dangerous pollutant can change that.
All life is based on the element carbon. Carbon is the major chemical constituent of most organic matter."
The statement; "Well over 90% of "carbon footprint" comes from water vapor." Is quite correct.Although carbon footprints are reported in annual tons of CO2 emissions, they actually are a measure of total greenhouse gas emissions. A greenhouse gas is any gas that traps heat in the atmosphere through the greenhouse effect. Because of the presence of greenhouse gases in our atmosphere the average temperature of the Earth is 14 ºC (57 ºF). Without the greenhouse effect, the average temperature of the atmosphere would be -19 ºC (-2.2 ºF).
Many greenhouse gases occur naturally through the natural carbon cycle, moving carbon from its solid form to the gaseous state, thus increasing atmospheric concentrations of carbon dioxide.
What is water vapor?
"Water vapor is water in its gaseous state-instead of liquid or solid (ice).
Water vapor is totally invisible. If you see a cloud, fog, or mist, these are all liquid water, not water vapor.
Water vapor is extremely important to the weather and climate. Without it, there would be no clouds or rain or snow, since all of these require water vapor in order to form. All of the water vapor that evaporates from the surface of the Earth eventually returns as precipitation - rain or snow.
Water vapor is also the Earth's most important greenhouse gas, accounting for about 90% of the Earth's natural greenhouse effect, which helps keep the Earth warm enough to support life.
When liquid water is evaporated to form water vapor, heat is absorbed. This helps to cool the surface of the Earth. This "latent heat of condensation" is released again when the water vapor condenses to form cloud water. This source of heat helps drive the updrafts in clouds and precipitation systems, which then causes even more water vapor to condense into cloud, and more cloud water and ice to form precipitation.
Interesting facts:
Water Vapor Cools AND Warms the Climate System? When water evaporates from the surface of the Earth, it cools the surface.
This keeps the surface from getting too hot. But because that water vapor is also the atmosphere's primary greenhouse gas, water vapor acts to keep the Earth's surface warmer than it would otherwise be.
So which effect is stronger, water vapor's cooling effect or warming effect? Interestingly, it is seldom mentioned in the global warming debate that the surface cooling effect of evaporation (which creates water vapor) is stronger than its greenhouse warming effect."
