Clean up your mess, youth tell climate talks inside and out

The generation of young people who will inherit a warmer future is telling the generation that caused carbon pollution to clean up its mess.

But they fear that message isn't getting through.

"It's our future. Our future is being negotiated, and we don't have a seat at the table," said 20-year-old Boston College student Julia Horchos.

Young people are attending the talks in Glasgow, Scotland, in unprecedented numbers -- and world leaders have credited their activism with reinvigorating negotiations aimed at avoiding catastrophic climate change.

But even among those who are inside the venue, nearly all are here as observers, like Horchos -- kept outside the rooms where the real decisions are being made.
