In a recent debate among environmental scientists, a claim was made that if global carbon emissions were reduced by 50% over the next ten years, the rate of ice melting in polar regions would also decrease significantly. Another scientist countered that such policies would require substantial economic sacrifices, as industries heavily reliant on fossil fuels might collapse. A study referenced in the debate indicated that countries with stringent environmental regulations typically experience short-term economic downturns but eventually recover economically over the long term.
Based on these statements, which of the following conclusions can most reliably be drawn?
