A scatter plot comparing countries based on total annual spending on food with the share of total consumer expenses on food. Kenya is an example where in absolute terms, relatively little is spent on food, but what is spent makes up a comparatively large portion of all combined consumer expenses. A map of mainland Europe, showing PFAS contamination sites. A clear accumulation can be seen in northwestern Europe and the east coast of Sweden, where the usage of firefighting foams containing the chemicals is recorded. A map of the Iberian Peninsula, showing the electrical potential of different sites in megawatts, grouped by their type of generation.

"Pascal Duclos’ aircraft shook like a toy plane as he and his co-pilot navigated 100 miles per hour winds over arid canyons, the arcing blue curve of the Pacific Ocean and rising plumes of smoke from the voracious Palisades Fire."
www.bloomberg.com/news/feature...
A large area of Topanga State Park and nearby residential areas are highlighted with the perimeter of the Palisades fire on Jan. 7, 2025. The flight paths of two Super Scoopers cover the area, returning from the Pacific Ocean back to the fire area more than 8 times in one hour, represented with a chart showing altitude increasing from zero when over water and more than 1,500 km in height when preparing for water drops.
