With only one round of talks left before the global leaders meet in Copenhagen this December, efforts to craft a new international agreement to reduce global greenhouse gas emissions are unfortunately making more headlines than actual headway nowadays.

If the world is to save itself from the undesirable consequences of global warming, all countries must work together now to reach a climate accord out of hope, not out of hard but usually short-sighted political calculation.

Though obstacles on the road to Copenhagen climate accord are never so obvious as nations just wrapped up two difficult weeks of UN climate talks in Bangkok early this month, the strongest message I got during a recent visit to Copenhagen is that we mankind must combat climate change, and we can do it.
