This week, delegates from nearly 200 countries are trying to wrap up their work at the successor to last year's climate conference in Copenhagen. And I'm one of about 2,000 journalists from around the world who are here to cover the event.
I've spent most of the morning weaving my way through checkpoints of armed Federales. The security here is squeaky-tight. which makes getting around between the widely spread-out conference venues a time-consuming challenge.
