I strongly recommend the blog of my (new) friend Bill Becker (Bill is the Executive Director of the Presidential Climate Action Project, a national initiative to develop a bold and decisive national climate plan. )
His latest post:
"Imagine you’re a well-to-do person attending a dinner of your peers. The food is top-rate and there’s plenty of it. Course after course is laid upon the table.
A group of less-advantaged people has been watching from the sidelines. When the dinner is done, you invite them to join you at the table. After the restaurant staff has served coffee, the bill comes. You and your rich peers insist that everyone now at the table must share in paying the entire bill.
If that seems unfair, then you have just understood the position of the delegates from emerging economies, now negotiating with their wealthier colleagues from the North over a climate deal at Copenhagen."
