pick an answer: If an industrial city imprents a cap-and-trade system for carbon emissions, how might this affect local instances of thermal inversion? No change, since cap-and-trade focuses on greenhouse gases rather than pollutants involved in inversions. Increased, if companies purchase additional allowances instead of reducing emissions Sporadic fluctuation because companies' emission reductions vary seasonally based on production demands Reduction due to financial incentives for lowering pollution levels
