Most of what you see in the mainstream media is how we produce CO2, and how CO2 can heat the planet. But they don't link the two to show that the amount we produce does and has heated the planet and they don't talk specifically about how even a small increase can be disastrous other than a rise in ocean levels.
The atmospheric CO2 concentration has increased from 310 ppm to 384 ppm in 50 years. There has been a lot of handwaving about how carbon dioxide in the atmosphere is a 'greenhouse' gas that is absorbing heat and preventing it from radiating into space but nothing credible quantifies the effect of that change in concentration. To list just a couple of the problems with the theory:
1) There is already an excess of CO2 in the atmosphere to seemingly provide all of the infrared absorption possible by carbon dioxide. Adding additional carbon dioxide does not increase the absorption effect since there is already an excess beyond what is needed.
2) Uncondensed water vapor has a 'greenhouse' effect 4x to 5x times greater than CO2. Similarly, though, there is already an excess of water vapor in the atmosphere so increasing water vapor does not increase the absorption.
3) Absorption of infrared radiation by any of the gases in the atmosphere causes the absorbing molecule to heat whereupon it almost instantly collides with another molecule contributing to an increase in temperature of the gas mixture, members of which then re-emit radiation which then continues on into space. A (slightly) warmer atmosphere would radiately slightly more heat to space leading to a balanced flow of heat rather than a buildup of heat at ground level.
Satellite imagery from as recent as 1979 shows enormously more ice than we see today.
No, it doesn't.
