California Wildfires: cumulative acres burned over time

Wildfires are raging across California (again). Always knew I would end up in hell but I imagined it was more of a spontaneous combustion type of event rather than a gradual descent into the infernal #everythingisfine pic.twitter.com/gl6otozX6f — Christopher Yee (@Eeysirhc) September 8, 2020 What I noticed over the years of “doom watching” is how the news only report on tabulated data. They lacked any sort of visualization to underscore the impact of these fires....

Firearm Sales: How are Americans coping with 2020?
