Many victims of the LA Wildfires are still tangled in a set of steep challenges. Many are uninsured or underinsured, and payouts have widely fallen far short of rebuilding costs, noted Thomas Chandler. ow.ly/ocOR50XTa4C #LAWildfires @climate.columbia.edu @us.theguardian.com
The Los Angeles wildfires were ‘the perfect storm’. Is the city ready for the next one?
After the devastating fires, neighborhoods pledged to build back stronger and better than before. A year later, they’re still untangling issues
