A recent review of how climate change could affect indoor air quality offers a fresh insight into the potential adverse public-health impacts of climate change. The author, William Nazaroff of the University of California said: “Attention is skewed and outdoor issues get much more attention than indoor issues. The research community needs to be reminded that the air around us indoors matters as much as, or even more than, outdoor air.” Nazaroff’s paper is part of the ERL Focus on Environmental Assessments in the Built Environment.
