The primary source of light for more than a billion people in developing nations is also churning out black carbon at levels previously overlooked in climate warming estimates, according to a new study led by researchers at UC Berkeley and the University of Illinois.
UC Berkeley-led researchers have found a dramatic one-third reduction in severe pneumonia diagnoses among children in homes with smoke-reducing chimneys on their cookstoves. Reducing wood smoke could have a major impact on the burden of pneumonia, the leading cause of child mortality in the world, the researchers said. A separate pilot study also found a link between prenatal maternal exposure to woodsmoke and poorer performance in markers for IQ among school-aged children.
Six Berkeley faculty members experts were selected by the Intergovernmental Panel on Climate Change (IPCC) to write the fifth comprehensive climate-change report.
Six international studies published this week in the British journel The Lancet show that cutting greenhouse gases, in particular ozone and black carbon, can save millions of lives worldwide in addition to slowing climate change.
