Greta Thunberg, a climate change activist learned to deliver the snark at 2021. She was particularly adept when she had to confront criticism and attack her foes.

While she became less active on Twitter in the second quarter of 2018, it gave us an inside look into her life. These are her most popular tweets.

Thunberg also used some snark in a tweet about a “magic wand” to alleviate problems. Thunberg argued that quick fixes were unfair and undemocratic.
