Today is the last day of the UN climate conference in Bali. The crucial negotiations have now entered their final hours.

No one's really sure how it will all turn out. It's becoming quite the cliff-hanger.

Will Canada back down and stop blocking progress? Will the world move forward and agree to deeper emissions cuts? Or will we get a watered-down deal that lets industrialized countries off the hook?

We won't know for sure until the gavel comes down at the end of the day -- whenever that is. Depending on who you talk to, the negotiations could finish by 6 p.m. or they could go straight through the night and into Saturday morning.

We put out a news release yesterday outlining what we hope will happen here in Bali

All that anyone can do now is wait.
