environmentalist, fir david at 10 tenborough, will address them on the importance of keeping global warming down to less than 1.5 degrees centigrade. while the leaders are listening to that, discussing among themselves how they can tie up the loose ends on that part of the agenda and the open society, how they should project democracies around the world, the importance of that will be on the table today. the fine-tuning of the final communique. i think we'll get to see that in about five hours or so. and then we'll be able to know the depth of agreement and hence where the bigger disagreements and gaps are. >> what's at stake specifically on the climate? because anything that they might decide on or announce as far as fighting global warming is nonbinding. this is a nonbinding forum. so we know there have been a lot of protests specifically targeted at this topic, right? fighting global warming.
