A Twitter thread discusses the cause of the 2018 Camp Fire in California, which was the most destructive in the state's history, burning most of the city of Paradise to the ground and causing 85 deaths. The fire was started by a faulty electrical transmission tower owned by PG&E, which had a broken C hook that was likely nearly 100 years old. The thread highlights the lack of maintenance and record-keeping by PG&E, as well as the role of climate change and poor forestry management in contributing to the disaster. The fire resulted in $16.65 billion in damages.
