Greta Thunberg may be a leading voice when it comes to environmental issues, but she seems to be establishing herself as a budding disability advocate as well.

Over Labor Day weekend, the teenage Swedish climate activist published an Instagram post responding to criticism of her appearance and actions. In the post, the 16-year-old Nobel Peace Prize nominee noted that she has Aspergers syndrome and wrote that her autism means Im sometimes a bit different from the norm. And given the right circumstances being different is a superpower.
