Thunberg in Denver.

“We will instead tell them, if they won’t do it, we will,” the 16-year-old said to loud cheers on Friday. “The world is waking up and we are the change. The change is coming whether you like it or not.”

Thunberg spoke for several minutes to a crowd of several thousand at Civic Center Park near the state capitol building. The rally highlighted Colorado activists, like Madhvi Chittoor, 8, who has campaigned in the state against plastics.

Thunberg again scolded leaders for not doing enough to fight climate change and for ignoring science. Echoing a line from an angry speech at the United Nations last month that drew global attention, she said several times of leaders, “How dare they,” with some in the crowd repeating the line.
