recent study from researchers at UC Irvine and Global Energy Monitor found that replacing aging coal plants with new gas plants that could operate for 30 years or longer — as America has done in recent years — might reduce long-term carbon emissions by just 12%. The difference is even less after accounting for methane, a pollutant that leaks from gas infrastructure and traps heat in the atmosphere far more powerfully than carbon dioxide over the short term.
