Halestorm's Lzzy Hale has praised Greta Thunberg as "our modern-day Joan of Arc," saying that the teenage climate activist is "sitting at a round table of young women who have inspired and shaped humanity." The Swedish teenager has gained international media attention in recent months for her outspoken activism on climate change, including delivering an impassioned speech to the United Nations Climate Action Summit calling out world leaders for not responding to the climate crisis with more urgency. Hale took to social media to share a photo of Thunberg at the U.N. podium and included the following message: "Our modern day Joan of Arc. @gretathunberg Thank you for your candor, grace,logic and beautiful anger. Wield your sword. You are sitting at a round table of young women who have inspired and shaped humanity." Hale went on to name a few other children who made a positive difference in the world through words and actions, including Ruby Bridges, Anne Frank, Malala Yousafzai, Claudette Colvin, Audrey Faye Hendricks and Mary Shelley.
