New Study Gives 150 Million Reasons to Reduce Carbon Emissions

Taking serious action on climate change now could mean saving hundreds of millions of lives across the globe, according to a new study published in Nature Climate Change on Monday by researchers at Duke University. The study looked at the human health benefits of holding global climate change to 1.5° Celsius (2.7° Fahrenheit) — the aspirational goal set by the Paris climate agreement. It found that taking significant steps to reduce carbon emissions in line with this goal would prevent more than 150 million premature deaths worldwide, largely through a decrease in air pollution. The study looked at three different scenarios for carbon emissions reductions — one scenario where carbon emissions were reduced rapidly to keep the planet below 2° Celsius (3.6° Fahrenheit) by the end of the century, another where emissions were reduced less rapidly (but still enough to keep warming below 2°C by 2100), and a third where emissions were reduced rapidly enough to limit warming to 1.5°C....
