Probably is a blind shot, but I would like to ask if somebody has calculated the impact in global warming of the direct heat. I am thinking for example in the human population (almost 7 billion with a constant  average temperature of 36.5 º C). And not only that, but the average temperature of all the cattle in the world kept by humans, (billions of animals that otherwise wouldn´t exist). Also we could think in the heat from fires (both wildfires and the small ones) and the heat that escapes from our homes, vehicules or industries.
