Could heat emissions cause global warming? I have calculated 6×1020J/a World heat production from human combustion, energy capture, waste heat and emissions to be 8.3 times greater than warming of oceans, land and atmosphere observed, but 216 times lower than solar forcing of 0.9 Watts per square metre assumed in a climate model (Trenberth 2009). The human effect is relatively small but cannot be ignored, because it acts like the last straw that broke the camel’s back and could cause global warming. Earth’s heat load is to absorb and radiate and a much larger quantity of heat day and night. That is relatively constant. The anthropogenic heat straws which add to the radiative camel are enough to shift the heat balance of the Earth, causing global warming.
Solar radiation warms the Earth’s surface, heat is convected into the atmosphere and eventually away into space. Trace carbon dioxide, 0.045% of the volume of the insulating gas blanket, absorbs heat like the other gases and is not chemically active like chlorofluorocarbons were — blamed for catalysing a hole in the ozone layer. Carbon dioxide has a very small part in global warming, which is probably caused by change in the Sun or orbit of the Earth. Increased carbon dioxide has probably been released from ocean water where most is dissolved, like the fizz bubbling from warming lemonade. Carbon dioxide is benign. An enhanced greenhouse effect caused by carbon dioxide is a myth without direct evidence. Phew — what a relief! This interpretation is based on sound science.
A shifted paradigm of climate science is in my satirical novel Animal Farm 2.
