Not so fast. CO2 was fine in the amounts present in pre-industrial society The earth was lush and green. CO2 IS a greenhouse gas.
Please get your facts straight. Geologic core samples show that a very long time ago (thousands or millions of years ago depending on whether you believe the young-Earth theory or the ancient-Earth theory) CO2 levels varied between current levels (currently at the minimum) and more than 20 X current levels. And during those cycles, the average global temperature varied between global ice age and global tropics, totally unrelated to the variations in CO2 levels. When both temperature and CO2 are plotted on a timeline, they show absolutely no correlation - they both vary very randomly.
And CO2 can't be a greenhouse gas. CO2 is a linear molecule, so it can only vibrate in 2 directions. Therefore it can absorb only 2 distinct frequencies (wavelengths) of sunlight. Water is a V-shaped molecule and it has 6 distinct oscillation modes, so it can absorb 6 different frequencies of sunlight. Furthermore, there is a lot more water in the atmosphere than CO2. So CO2 absorbs less than .02% of the sun's energy, whereas water absorbs more than 99.97% of the sun's energy. Water is the greenhouse gas. The
only greenhouse gas. CO2 isn't even a drop in the ocean. The problem is: politicians can't tax or regulate the water cycle! As for other gasses, they are present in far lower amounts than even CO2, so they have an even lesser effect.
Besides, what's wrong with a warmer climate? Plants grow better in a warmer climate. That's why gardeners build greenhouses. In historical times (hundreds of years ago), the climate was notably warmer. Remember when Egyptians were depicted in ancient paintings as being shirtless and Greeks and Romans wore flimsy togas? Coastal cities weren't flooded and polar bears weren't extinct. And more of the Earth's land area was farmable. Then a series of volcanic eruptions (Krakatoa and others) spewed so much volcanic ash into the atmosphere that it sent the world into a mini ice age that has never abated. Until Al Gore (a politician, not a scientist) went around spewing his lies about CO2, scientists were worried that this mini ice age would someday turn into a major ice age.
Venus has an atmosphere practically made out of it. I think the surface temperature is somewhere near 800 F.
And no, that fact that it's closer to the sun doesn't explain its vast surface temperature differential from that of earth.
Venus' atmospheric pressure is approx. 100 X Earth's. And Venus' atmosphere contains a lot of sulfuric acid.
Speaking of carbon emissions, fluorocarbons are especially nasty as well. In fact, we almost hair-sprayed a hole in the ozone layer with them..
Again, wrong. That theory was proposed by a college student (obviously not a science or engineering major) for his master's thesis and is almost as full of holes as Al Gore's "climate change" fairy tale. While chlorine may indeed cause the reduction of O3 to O2, O3 is produced by the action of ultraviolet radiation from the Sun, and O3 blocks UV. If there's less O3, more UV gets through to produce O3 which then blocks the UV. It's a self-regulating mechanism that we engineers call "negative feedback".
Furthermore, the hole in the ozone layer is over Antarctica - a part of the world that receives NO sunlight (and therefore no UV to produce) for most of autumn and winter.
Of course there's a shortage of O3 there! And so what? Antarctica is so cold that if you were to step outside without several inches of padded clothing, you'd likely freeze to death before you could even close the door behind you.
Scientists have known about the 11-year cycle in the Sun's activity for a long time, whereas satellite observations of O3 levels over Antarctica have only been made for a much shorter time - not long enough to learn of any long-duration trends that aren't caused by cyclic solar activity. Once again, politics, not science rules! Politicians can't regulate solar activity, so they picked on something they
could regulate.
