Abstract Drivers of forest wildfire severity include fuels, topography and weather. However, because only fuels can be actively managed, quantifying their effects on severity has become an urgent research priority. Here we employed GEDI spaceborne lidar to consistently assess how pre-fire forest fuel structure affected wildfire severity across 42 California wildfires between 2019–2021.

The Covid-19 pandemic represents the single largest challenge to global trade for decades. With restrictions of varying severity coming in and out of force around the world on a rolling basis for the past two years, normality for international trade is by now hard to remember.
