I would like to see some evidence that a greenhouse effect in the atmosphere has ever been measured and quantified....Surely with 97% of scientists on board, it has actually been measured...Hasn't it?
The answer is no, it has not been measured. It is a hypothesis unprovable by any known experiment...unmeasurable by any known technology....and fervently believed in by people whose intelligence and ability to think critically is questionable.
About a dozen years ago, when there was still a lot more evidence supporting the AGW position, I was in a debate similar to this one. It dawned on me that the person I was debating had no interest in the facts. It was vitally important to them that AGW be real, they desperately needed it to be real. It was then that I stopped debating global warming, and decided that I would only mock the proponents. So I apologize in advance for not engaging in serious debate with the zealots here.
I posed the question of greenhouses to Abraham because the question itself reveals the fraud involved in AGW.
A greenhouse works by impeding convection with a physical barrier. In convection, water vapor traps heat and carries it away. The glass keeps the vapors trapped and thus retards convection. If the greenhouse becomes too warm, opening windows at the top of the greenhouse allows convection and cools the atmosphere inside.
So, does the atmosphere of Earth work this way? Is there a physical barrier of CO2 that blocks convection? Did we 'close a window' that was keeping the Earth regulated at a cooler temperature?
Well, no... Since we sit in the vacuum of space, convection outside of our atmosphere would quickly result in the extinction of all life on the planet. Further, CO2 is not a physical barrier at all.
Greenhouses retard convection, the mechanism that Abraham misattributes retards radiation. I know, it sounds like I'm picking nits, but this is actually a vital question, because unlike the physical barrier impeding convection, the process of retarding radiation is far more complicated.
The basic greenhouse effect works like this;
A key concept in this is "loading." the reality is that the components of the troposphere cannot exceed 100%. In simple terms, for there to be more CO2, there must be less of another gas. So the way CO2 would affect the transfer of radiation in to space is by replacing a gas that has a lower ability to absorb and delay transference. To affect Earth's total tropospheric greenhouse effect the CO2 would need to displace an inert gas.
Abraham has a financial stake in promoting the myth of AGW. When the con fails, it will literally impede cash from taxpayers from flowing into his pockets. So I expect him to fight the exposure of the AGW fraud with everything he has.
