The Copenhagen climate negotiation was a lost opportunity.

The substance of the Copenhagen Accord presented at the end of the negotiation is frighteningly hollow. It ignores the demands of the climate justice movement and disregards the rights of poor communities.

The impacts of climate change -- floods, droughts, and natural disasters -- threaten food security, livelihoods, and the very right to survival for millions of the world's poorest people.

Instead of concluding more than two years of work by 190 countries to reach a global agreement, the Copenhagen Accord was put together behind closed doors by a few powerful countries, led by the US, at the last minute with no regard for the established United Nations process.

Now, more than ever, we need President Obama to stand up and help lead the world forward to address the climate crisis. Send him a letter asking for his leadership on key steps needed to help us avert climate catastrophe.
