If you live in the Western USA, you understand with the direct consequences of fires. From Montana's great mountain forests attacked by beetle infestations in overgrown timber; to the high deserts of Arizona where explosive firestorms have killed 'hotshots' fighting blazes; to California's famous wine country that recently went up in flames, wildfires have been raging out of control. Megafires, burning more than 100,000 acres and rising, are the result of ecological and social changes we caused to western landscapes over a century of misguided management in a rapidly changing climate.

Forest Service ecologist Paul Hessburg offers his perspective on how this happened and why fires are now so intense.
