Poorly circulated air raises potential exposure to contaminants

Having good room ventilation to dilute and disperse indoor air pollutants has long been recognized, and with the Covid-19 pandemic its importance has become all the more heightened. But new experiments by indoor air researchers at Lawrence Berkeley National Laboratory (Berkeley Lab) show that certain circumstances will result in poor mixing of room air, meaning airborne contaminants may not be effectively dispersed and removed by building level ventilation.

Latest IPCC report suggests urgent action to cut emissions

Our planet’s oceans, forests, and soils perform a valuable service, absorbing half of our carbon dioxide emissions. But the more that our planet warms, the more these so-called “carbon sinks” weaken in their ability to perform this service. If we continue our current trajectory of high emissions of greenhouse gases, by the next century not only will oceans and forests absorb less carbon dioxide, but they could also even reverse their role and become carbon sources.
