While many scientists and climate change activists hailed December's Paris agreement as a historic step forward for international efforts to limit global warming, the landmark accord rests on a highly dubious assumption: to achieve the goal of limiting the rise in global average temperature to less than 2 °C (much less the more ambitious goal of 1.5 °C), we don't just need to reduce emissions of carbon dioxide to essentially zero by the end of this century.
