Global warming theory is phony

The global warming theory states that carbon dioxide rises into the stratosphere, forming a shield around the earth and, like a greenhouse, traps heat onto the earth’s surface. Basic chemistry and the law of gravity, combined, verify this is impossible.

The molecular weight of air is 28 and the molecular weight of oxygen is thirty-two. Mount Everest climbers and fighter pilots need oxygen tanks/masks to survive at high elevations because oxygen is a heavier gas than air. Therefore, very small quantities of oxygen exist at high elevations due to the law of gravity. The molecular weight of carbon dioxide is 44, a much heavier gas than oxygen. Consequently, by the law of gravity, carbon dioxide cannot possibly rise into the stratosphere in sufficient quantities to form a shield around the earth just as a slab of concrete will not float in the ocean.

I do not deny the earth is warming but the global warming theory is phony. I am a graduate chemical engineer. Check your chemistry and physics books. What is stated above is fact, not theory. Therefore, politicians and news reporters are full of you-know-what.
