The Earth Summit in Rio begins today. What’s that? You thought it started weeks ago? Very understandable.

You can watch the plenary sessions here, or streaming below.

Later today, 17 year-old Brittany Trilford will speak to the assembly. (You can read Greg Hanscom’s interview with her here.) We’ll update this post after she does.

Non-governmental organizations continue to announce new initiatives related to the convening. Development banks yesterday committed $7.2 billion to help poor countries prepare for climate change. This morning, a group of banks made a $175 billion commitment to create sustainable transport systems.
