About 200 protesters marched through downtown Chicago Monday evening to demand lawmakers declare a climate emergency.

The group initially rallied at a main downtown plaza across from City Hall, where they hosted speakers and cheered on a simultaneous student protest.

Meanwhile, around two dozen Chicago-area teens dressed in all black gathered across from Trump International Hotel and marched to City Hall, where they staged an 11-minute “die-in.”

During the demonstration, the teens laid on the ground in silence, many with their palms facing up, revealing phrases such as “climate emergency” written in red paint.

“We did this for 11 minutes to symbolize the 11 years we have left before the adverse effects of climate change become unavoidable,” said Isabella Johnson, 17, State Lead for advocacy group Illinois Youth Climate Strike.

Johnson was referring to a 2018 report by the United Nations’ Intergovernmental Panel on Climate Change that stated we only have 12 years left to prevent irreversible damage from climate change.

Organizers initially said 16-year-old Swedish activist Greta Thunberg would be present at the protest, but she was not in attendance.
