Washington •There is an overlooked benefit to greatly lowering carbon emissions worldwide, a new study says. In addition to preserving Arctic sea ice, reducing sea-level rise and alleviating other effects of global warming, it would probably save more than 150 million human lives.
According to the study, premature deaths would fall on nearly every continent if the world's governments agree to cut emissions of carbon and other harmful gases enough to limit global temperature rise to less than 3 degrees Fahrenheit by the end of the century. That is about a degree lower than the target set by the Paris climate agreement.
