Earth’s heat balance is certainly complex, but higher temperatures could come from retention of increased heat from Earth sources, with solar radiation absorption and emission continuing as in the past. Modelling of changes to the world energy balance can account for global warming and the futility of the net zero concept.

Heat energy to warm Earth’s land, oceans and atmosphere, is emitted by respiration of living things, by combustion of vegetation and fossil fuels, by capture of renewable energy replenished by the Sun and by geothermal processes. Some heat produced is radiated into space, but my calculations indicate the remainder is sufficient to add to normal solar warming and cooling, causing warming noticeable near city heat sources. 

Warming would not in the least be reduced by substituting for fossil fuels with solar, wind or hydro energy supplies. Warming in the environment is caused by spent inefficient energy consumed.  Reduction to net zero could require cutting energy consumption and waste by human populations to a low level, until entropy increase is balanced if possible by removal in endothermic reactions, such as photosynthesis, which absorbs heat with light. Deindustrialisation may be necessary. The theory of warming by greenhouse gases is considered in my previous post here Greenhouse Gases Not To Blame.

My satirical book Animal Farm 2 explains paradigm-shifted climate science.
