Call it hype if you wish, but even then the shrinking glaciers, pack ice and tundra should tell you something, Crab. I am amazed at how a little ignorant political spin, properly laid, can "confuse" people. Of the approx 1,000 peer reviewed scientific publications that discuss climate change in the last decade, zero, zip, nada have embraced your point of view. All, every one, the entire bunch have stated that we are changing our climate. Of course, a few non-scientist White House lawyers agree with Crab, so there ARE two points of view. I personally called the head of the US climate labs in Colorado to ask him what he thought about the "debate". He laughed, and said he should really be crying out.
That being said, the actual carbon cost for the van vs the helo is not just covered by the vehicles, as that lame web site describes. The van needs a road, and that road needs a grader, paving trucks and an entire infrastructure of police patrol, tax guys, repair crews, fencing, gasoline stations and such muck to keep it operating. These all add measurably to the "carbon toll" of that van, but are counted as zip.
The helicopter carries its infrastructure on its back, asks nothing else, but with a higher fuel flow, it looks less efficient.
