A few weeks ago we asked you to send in your questions on climate change for our reporter Mark Schapiro while he was in Copenhagen covering the talks.

Many of you did, sending them via webcam, email and from the summit itself. Questions came in from Tibetans, Russians, Pacific Islanders, Brazilians and many Americans.

As soon as the Bella center shut up shop at the weekend, we found the festive if freezing King’s Square in downtown Copenhagen to put your questions to Mark, and get his initial thoughts on what had been achieved there.

The analysis of what did or should have happened at the summit is only just beginning to surface, and we’ll be following the road from Copenhagen to Bonn and Mexico Ciity where the next crucial stages of these talks will take place in the coming months.

Over the next year, FRONTLINE/World and CIR will report on key issues of climate change in a joint project—Carbon Watch—focusing on the multi-billion-dollar carbon trading market. We’ll look at which proposals to reduce emissions by 2020 really add up; at the hidden interests behind these solutions; and the new industry players.
