Actually....definitely debunked! The backradiation from CO2 to the Earth's surface is a scientific fact that even denialist scientists like Dr. Roy Spenser have to acknowledge.
And you poor anti-science retards have no evidence at all to support your lies and fraudulent claims.
Sorry thunder....roy was debunked post haste on that little experiment...the manufacturer of the infrared thermometer he was using contacted him and told him point blank that the thermometer was not measuring back radiation..like so many climate change believers, he is apparently easily fooled by instrumentation.
the thermometer was not measuring back radiation..
It was measuring temperature. How did it manage to do that?
It is measuring IR radiation but the problem with doing that with the IR gun Spencer used is that the temperature is computed by the instrument assuming an emissivity of 0.9 for everything it is pointed at.
And in add in addition to that the instrument reading does not give you a true reading of the watts/m^2 of a distant spot...which increases in size at larger distances and assumes that the entire area radiates nearly at the same intensity as the hotter spots in it. In other words the cooler regions don`t affect the reading as much as they should.
So if he points it straight up at the sky pick a distance and use 1/24 th of it as the spot radius and square it times pi. How sure are you that the entire area in that (huge) spot is at the same temperature?
Maybe some where in the middle of a huge desert at a cloudless night sky it is...but no way would it be at a uniform temperature when the terrain is not all the same...with parking lots, buildings, or forest with clearings, farm fields, rivers and lakes etc. Get the picture?
I`m also quite certain he would have seen a whole lot less "back radiation" in the mid-west and the western parts of the USA:
