This is is my explanation of the greenhouse effect and what it REALY is for people everywhere by way of a story: I remember the greenhouse effect from my childhood visits every summer to my grandparents in Saint Louis.. In the city of Saint Louis in MO, USA, there is a large park called Forest Park. Every summer we would go to Forest Park to fish with worms and fishing poles. When I was five years old a huge glass covered botanical garden was built. Three stores high if I remember. Inside EMF and photons from the Sun penetrated the glass. That caused the inside of the botanical garden to warm up quite nicely and with all the watering of the plants, the relative humidity increased making it a real "hot house.” BUT all that hot hair was trapped inside because the gardens were entirely covered with the glass and the heat could not exit quickly. Thus it stayed warm at night and the plants grew many times faster than they would outdoors in the cooler temperatures. And plants need CO2 for photosynthesis to grow bigger so CO2 was pumped in from storage tanks. I remember my father telling me at the time they increased the CO2 concentration to make the internal CO2 levels 5 to 6 times higher than the ambient outdoor concentrations of CO2 which may have been 350 ppm average in those days. The public was allowed inside also, so even more human produced CO2 (from living…) was introduced inside. My father, a Ph.D. in physics, told me at the time that facility was a greenhouse. Why was it called a greenhouse? Because all the plants inside were very green and large because of the warmth and high levels of CO2. Now can someone criticize me for writing about the way a greenhouse operates? I ask how many large heavy buildings have you seen floating around in the air thousands of feet above ground growing plants. I suspect the answer will be unanimous. Zero. Sorry but greenhouses do not float around in the air. A trace amount of the gasses we put into greenhouses to make them work more efficiently does occur in the air. But only 0.04 percent of the air is such a gas which scientists and political numskulls call Carbon Dioxide and the chemical formula is CO2. Now is this so hard to understand?
Tim adds:
Exactly. They argue the CO2 acts like the roof of the greenhouse and holds in heat, but with just four molecules out of every TEN THOUSAND being carbon dioxide, and three of the four (actually more) having already been there, how does that work exactly? A chicken coop with a wire roof would be better at trapping heat than this miniscule layer of carbon dioxide. I would add water vapor is by far the most powerful greenhouse gas in the Earth's atmosphere and we don't understand it at all. Furthermore, CO2 has a loagarithmic heat-holding, meaning it saturates at it's bandwith after a two degree warming, so it cannot hold any more heat. Hence even if it IS holding heat in the atmosphere it craps out at two degrees. The primary argument they use is that the warming from CO2 will evaporate more water vapor, which will lead to more CO2, and this will lead to the permafrost disappearing and all the methane going into the atmosphere. Runway greenhouse effect. But is that reasonable? Certainly on Mars with a 95% CO2 atmosphere they do not have that; when Mars warms and more CO2 goes into the atmosphere it kicks up dust storms and cools things back down. The same may well be true of increased water vapor, leading to more clouds which block the radiation. BTW there has been no net increase in precipitation worldwide in recent years. In fact the Earth's albedo has decreased in recent years (albedo being a measure of reflectivity) and THAT should not happen in a carbon dioxide-driven planetary warming as more water vapor should mean more clouds and more snow in the Arctic. That that hasn't happened suggests this whole thing is a farce.
