I think that the price of vehicles is keeping many from purchasing a new one. $60K for a new diesel F250 is a hefty price tag.

The AGW crowd....(Anthropological [humans] Global Warming) , REALLY argues with that, and they cite some really high powered scientists to back up their claim.....
But when you do a little research yourself, you find that they (very conveniently IGNORE marine volcanoes and the fact that volcanoes are outgassing CO2 even when they aren't erupting as is "other" tectonic activity.)
It seems that Chiodini et al. (2004, p. 3) may have considered it somewhat implausible that a meagre 62,000 square kilometre area on the earth's surface could be responsible for 10% of all magmatic outgassing, worldwide. How else could they come to conclude that their result suggested underestimation in the first place? They then go on to point out what they think has been left out of the picture. In context, this "CO2 Earth degassing from non-volcanic environment" which "affect almost all tectonically active areas of the world." refers to magmatic outgassing due to tectonic activity rather than volcanic activity. This points to a largely unstudied area and, certainly, extrapolating the results of the study across all tectonically active areas will still produce a very high figure for magmatic outgassing of carbon dioxide, worldwide (i.e. much more than 1.0 GtCpa). However, in the absence of more representative sampling, it remains an incontrovertible fact that, at this point of history, we have absolutely no idea how much volcanic (i.e. magmatic) Carbon Dioxide is annually released into the atmosphere at the surface of the earth.
The entire article is linked below if anyone has the patience to read it!!
Volcanic Carbon Dioxide
So while it's generally true that "ONE" volcano doesn't produce "more" CO2 than all the cars in the world, It's very possible that the several million marine tectonic events + marine volcanoes possibly do dwarf human production of CO2 by a wide margin.
Of course, when anyone calls attention to some of these inconvenient facts, they're immediately called "Climate Deniers" and MUST of course, be silenced...........
