Last night, I went to the exhibit "Native Land, Stop Eject", a 360-degree room with powerful visual depictions of data related to global warming, floods, droughts and global migration.

It was developed by artists--including my longtime friend Laura Kurgan--for the Kunsthal Charlottenborg museum in Copenhagen. This 45-second video provides a feel for how many cities will be underwater worldwide with the projected 1M rise in sea levels, given rising global temperatures.

It is Sunday and there are no scheduled events in the Bella Center. It is supposed to be a day of rest, but how can anyone rest when there is so far to go and so much to do? I took a run along the river and tried to breathe. I interviewed National Wildlife Federation CEO Larry Schweiger as part of a strategic analysis I am doing on how the clean energy and climate movement can do better.

I also went to a six-hour strategy session with the international Climate Action Network to take stock of where we are and how we can deploy our forces here and at home in the next few days to get a fair, ambitious and binding treaty. The chasm between developed and developing countries is so wide, and the U.S. is so key to the next week's actions. That's why we need you to call President Obama for a fair and binding treaty and to keep up the calls all week!

I feel tired and sad for our planet and its people.

This video from the same museum exhibit of indigenous Ethiopian girls singing to the backdrop of their Native Lands captures my passion for the quiet beauty of the world we are fighting to preserve.
