| Where have we gone wrong in our understanding of \'climate change\'? Think, are ordinary humans really to blame for extra CO2 emissions. Is CO2 really the problem or, is it possible that science of weather today is somewhat confused about it all? In this article, I will attempt to debunk this myth.
Yochan Krushnir who "is a research professor at Lamont-Doherty Earth Observatory, in the Division of Oceans and Climate Physics" says this on the subject in You Asked: " If CO2 Is Only 0.04% of the Atmosphere, How Does it Drive Global Warming? And why isn’t water vapor the major driving factor?"
Krushnir: "Earth absorbs energy from sunlight, but as the surface warms, it also emits energy in the form of infrared radiation (which we know of as heat) out into space. Water vapor and CO2, however, act like a cap, making it more difficult for Earth to get rid of this energy. Without gases like these to absorb the energy, our planet’s average surface temperature would have been near zero degrees Fahrenheit." He adds: "About 99 percent of the atmosphere is made of oxygen and nitrogen, which cannot absorb the infrared radiation the Earth emits. Of the remaining 1 percent, the main molecules that can absorb infrared radiation are CO2 and water vapor, because their atoms are able to vibrate in just the right way to absorb the energy that the Earth gives off. After these gases absorb the energy, they emit half of it back to Earth and half of it into space, trapping some of the heat within the atmosphere. This trapping of heat is what we call the greenhouse effect. Because of the greenhouse effect created by these trace gases, the average temperature of the Earth is around 15˚C, or 59˚F, which allows for life to exist.
CO2 makes up only about 0.04% of the atmosphere, and water vapor can vary from 0 to 4%. But while water vapor is the dominant greenhouse gas in our atmosphere, it has “windows” that allow some of the infrared energy to escape without being absorbed. In addition, water vapor is concentrated lower in the atmosphere, whereas CO2 mixes well all the way to about 50 kilometers up. The higher the greenhouse gas, the more effective it is at trapping heat from the Earth’s surface.
The burning of fossil fuels affects the concentration of CO2 in the atmosphere. Before the industrial revolution, the amount of CO2 in the atmosphere was about 288 ppm. We have now reached about 414 ppm, so we are on the way to doubling the amount of CO2 in the atmosphere by the end of this century. Scientists say that if CO2 doubles, it could raise the average global temperature of the Earth between two and five degrees Celsius. We are already increasing the amount of energy that bounces back to the Earth. Because of the greenhouse effect, this is causing global warming with its many destructive impacts.
Both water vapor and CO2 are responsible for global warming, and once we increase the CO2 in the atmosphere, the oceans warm up, which inevitably triggers an increase in water vapor. But while we have no way to control water vapor, we can control CO2. And because we are increasing the amount of CO2 in the atmosphere by continuing to burn fossil fuels, even in relatively small amounts compared to the entire mass of the atmosphere, we are disturbing the entire heat balance of the planet."

I can spot many discrepancies in this explanation. First one: Since the two layers of gases can not mix and are positioned at two different altitudes, the smaller group of CO2 is much higher than the H2O group [clouds that discharge periodically over the earth] how can they interact with each other? They obviously do not. Air pressure decreases with altitude. "At sea level, air pressure is about 14.7 pounds per square inch (1 kilogram per square centimeter), and the atmosphere is relatively dense. At 10,000 feet (3 km), the air pressure is 10 pounds per square inch (0.7 kg per square cm), which means molecules of gas that make up the atmosphere are less dense."

There is simply not enough CO2 up there to form a blanket which would trap the heat, and the low atmospheric pressure means molecules are far apart from each other so they can not emit heat radiation back to earth. The two strati can not interfere with one another.
Second: If the two are separated and the stratosphere has ozone in it that absorbs sun\'s UV radiation, it is likely that CO2 would share its energy with ozone molecules. Since ozone in our stratosphere reaches up to 1,000 degrees Celsius, because it absorbs solar radiation, isn\'t this evidence pointing then to the sun as a causation of the \'so called\' global warming?
