The article states that the overwhelming majority of economists support a tax on carbon emissions as the most effective solution to address climate change. This would provide an incentive for individuals and businesses to reduce their carbon emissions and would generate revenue that could be used for clean energy initiatives or other measures to combat climate change. A "cap and trade" system, which involves giving away permits to emit carbon, has been criticized for being too complex and potentially allowing companies to game the system. Expanding or enforcing regulations may also be less effective than a carbon tax in reducing emissions.
