Gruner’s Canon prints innate heat and airs as the environmental frame, crowding a fuel-emissions reading
Gruner 1930 prints the Canon’s airs, waters, places, and innate-heat physiology as the way a body meets climate and fuel. A miasma-and-heat frame can delay treating combustion smoke, coal, and later household fuel as a distinct security and health problem. In the causal graph this event weakens Energy Security, a driver that strengthens Poverty headcount ratio at $3.00 a day (2021 PPP) (% of population) — an improving welfare path.

Gruner 1930 prints the Canon’s airs, waters, places, and innate-heat physiology as the way a body meets climate and fuel. A miasma-and-heat frame can delay treating combustion smoke, coal, and later household fuel as a distinct security and health problem.
Context
Split any improving observation of airs. Medium confidence on unique industrial-era coefficients.
Avicenna is not the sole author of every later object, law, or museum label that uses the name. Shared work with courts, excavators, printers, spouses, officials, and later states does not erase a documented role, and it does not make an ancient person the signer of a twentieth-century statute.
