A study of biomass burning aerosols led by University of Wyoming researchers revealed that smoke from wildfires has more of a cooling effect on the atmosphere than computer models assume.
"To understand how the climate has changed over the last century we need to know as reliably as possible the natural atmospheric conditions before the industrialization," says Associate Professor Federico Bianchi from the...
A survey of peer-reviewed studies shows that universal mask wearing (as opposed to wearing masks in specific settings) does not decrease the transmission of respiratory viruses from people wearing masks to people who are...
From WeatherBell Analytics: A mean looking dust plume will meander across the Atlantic during the next 10 days. It will help to keep a damper on any early-season tropical formation in the main development region. It isn’t...
