Teen climate activist warns EU that it's time to panic

Swedish teenage environmental activist Greta Thunberg says time is running out to halt climate change and she's urging European politicians "to panic."

Thunberg told EU lawmakers Tuesday: "I want you to act as if the house is on fire."

During a speech met with a standing ovation, Thunberg fought back tears as she warned about rapid species extinctions, soil erosion, deforestation and the pollution of oceans.

In a reference to the international funding effort launched to rebuild the fire-ravaged Notre Dame cathedral in Paris, she urged the lawmakers to use "cathedral thinking" to tackle climate change.
