the global climate summit. where were you when this was happening? what is it like? >> so i was hosting with al gore the 24 hours of climate reality. it has been going on for five years this 24 hour broadcast delivered to nine nations tonight. was interviewing and with the mayor of paris hours before this happened. francois hollande was supposed to be on our set tomorrow night. we are all at the base of the arc detriumph. the show broadcasting 24 hours throughout this time period supposedly is on lockdown right now. i can tell you we raced to get to the cameras here. there is an eerie, eerie quiet in paris tonight. anyone that we tried, a taxi, all taxis had red lights on.
