Research linking fine particulate pollution and premature deaths is under attack in the United States and other countries. nature.com/articles/d4158โ€ฆ nature.com/articles/d41586-019

Rapid global shift to renewable energies can save millions of lives.

Fossil energy is the main source of and related health burdens.


...improvements in air quality in the United States between 1990 and 2010 reduced deaths from by nearly half.


The amount of premature deaths caused by long exposure to high concentrations of particulate matter in the atmosphere is larger than expected: 8.9 million in 2015.
