Black carbon, a potential global warming gas causes__________.

  1. human morbidity

  2. premature mortality

  3. both a and b

  4. asthma

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Black carbon consists of pure carbon in several linked forms. It is formed through the incomplete combustion of fossil fuels, biofuel, and biomass, and is emitted in both anthropogenic and naturally occurring soot. Black carbon causes human morbidity and premature mortality.
