Ahh, the inevitable goal-post shift that we all knew was coming...

My "explanation" of the contribution is that it's negligible. It probably has about as much impact as a flock of birds taking off in Los Angeles has on the weather in San Diego.

I suppose that's correct, technically. Here's what you said:

When confronted with the ridiculousness of your argument, you didn't back down; you didn't say that it was just a contributor to the greater problem of warming; you did nothing but defend your "heat from engines" nonsense.
Sorry, but you've been wholly owned in this thread. Not a single member of the hopeless AGW congregation has tried to back you up, and they're quick to jump in the fight if one of their own is taking a beating. That should tell you something.
But hey, if you want to keep posting about it, please feel free to continue. I'm having a blast watching you make a complete fool of yourself, and reducing the credibility of the AGW supporters in the process.
Summary so far: If we consider the Solar Constant (1,353 watts/square meter) to be 100% of the incoming solar energy in space approaching Earth, about 34% of that energy gets reflected off clouds and dust particles and the Earth. That leaves around 893.0 w/m2 or 283.6 Btu/f2/hr to actually get TO the Earth. This is for an AVERAGE location, so when the Sun is high overhead and there are no clouds, the instantaneous amount can be a little higher than this, as high as about 340 Btu/f2/hr, or 1,070 Watts/sq. meter. On the clearest possible day, this is about the best solar energy input that is possible. However, on the average, the 283.6 Btu/f2/hr is more realistic.
So the sun delivers about 283 BTU per hour per square foot.
According to here the earth is 5,502,532,127,000,000 square foot... <gets out calculator...
That's 1,557,216,591,941,000,000 BTU's per hour the sun delivers to the earth.
Moving onto oil the US consumes a little over 7 billion barrels of oil per year, that's total including all petroleum products. 42 gallons to the barrel so we get 294,000,000,000 gallons of oil per year. Well use the BTU content of fuel oil which is just under 140,000 BTU's per gallon which gives us a grand total of :
41,160,000,000,000,000 BTU's per year from oil.
If we divide the amount of BTU's of the oil into the sun BTU's you get:
37.8, in other words at current oil usage in the US it would take almost 39 years to deliver the same amount of heat the sun delivers in one hour.

I like it when people make ridiculous claims like this, I always learn something researching it.... Anyhow..

Haven't you ever felt a hot engine? It's HOT! You don't think that the heat radiating off your gas-guzzling SUV has an effect on the global temperature? DENIER! DENIER!
