As the curtain rises tomorrow in Cancún, Mexico, on the next round of international talks on climate change, expectations are low that the delegates will agree on a new treaty to reduce emissions that contribute to global warming. They were unable to do so last year in Copenhagen, and since then the negotiating positions of the biggest countries have grown even further apart.

Yet it is still possible to make significant progress. To give these talks their best chance for success, the delegates in Cancún should move beyond their focus on long-term efforts to stop warming and take a few immediate, practical actions that could have a tangible effect on the climate in the coming decades.

The opportunity to make progress arises from the fact that global warming is caused by two separate types of pollution. One is the long-term buildup of carbon dioxide, which can remain in the atmosphere for centuries. Diplomacy has understandably focused on this problem because, without deep cuts in carbon dioxide emissions, there can be no permanent solution to warming.
