What physical evidence supports the contention that carbon dioxide emissions from burning fossil fuels are the principal cause of global warming since 1970?
If you have it....lets see it. If you don't....then lets hear your best excuse for not providing it.

What a steaming pile of bullshit...
I am short on time now, but will get around to tearing his claims apart with observed, measured evidence... We might start with his claim that venus is hot because of a greenhouse effect....for a greenhouse effect as described by climate science to exist, first the ground must be warmed by sunlight and then in turn radiate IR outwards...the clouds on venus are so thick that very little solar energy ever reaches the surface of the planet...so the planet's surface isn't being warmed by solar energy...then there is the very troubling fact that the night time side of venus is the same temperature as the daytime side of the planet even though the night time on venus lasts for about 120 of our days...do explain that one...
The temperature is what it is on venus due to incoming solar energy and the extreme density of its atmosphere and the pressure that generates...much like the extreme temperatures found deep in the atmospheres of the gas giants like saturn and jupiter...very high temperatures, no greenhouse gasses, very little sunlight...
I will address more of what he calls empirical evidence later as time permits...did you notice where the paper came from? The vatican? really? If the paper had any merit, and actually provided empirical evidence of man's influence on the global climate that it might have been published in an actual scientific journal rather than the Pontifical Academy of Sciences, at the Vatican?
Once a dupe..always a dupe it appears...
I will get to the rest in time unless someone else beats me to it....anyone with even basic knowledge could tear that paper down...
