Fire is the fourth element. It destroys and creates something new. In its heat, colors, and magnitude, it provides a terrifying spectacle as much as an existential threat. Today, it speaks as much to the fragility of human structures as to the damage wrought on nature: the fire at Notre Dame Cathedral in Paris, forest fires from the Amazon to Australia, and infernos in California so colossal that the sky turned red. Reason enough for the Prix Pictet, the world's leading award for photography and sustainability, to dedicate this year's photo book to the many facets of fire. Selected by photography experts from around the world, this impressive publication features 100 images from the Prix Pictet shortlist and beyond. As compelling in its visuals as it is in its messaging, this is an unforgettable document of an elemental force, and of the increasing extremes of climate change.
