Fire blankets can protect buildings from wildfires

Wrapping a building in a fire-protective blanket is a viable way of protecting it against wildfires, finds the first study to scientifically assess this method of defense. Rigorous testing reveals that existing blanket technology can protect structures from a short wildfire attack, but for successful deployment against severe fires and in areas of high housing density, technological advancement of blanket materials and deployment methods, as well as multi-structure protection strategies, are needed.

Heat waves could increase substantially in size by mid-century

Scientists found that by mid-century, in a middle greenhouse emissions scenario, the average size of heat waves could increase by 50%. Under high greenhouse gas concentrations, the average size could increase by 80% and the more extreme heat waves could more than double in size.
