This is a key issue, but not for the reasons one may think. It has a momentum all of its own and to even murmur that it may not be all that it seems, is political and social suicide. Oh well, too bad. It just doesn't add up.
Copenhagen is the latest in a line of misguided affairs to change something which cannot be changed (the climate) and to ignore the real issues which threaten our common existence. CO2 is made out to be the enemy. We are made out to be evil if we propagate high-carbon deficit technologies or processes, but saviours of ourselves and the entire world if we change our bad carbon ways.
To save ourselves let's start with this: stop the greed. Stop all greed everywhere. Stop it. Don't fool ourselves: carbon is not the problem, greed is. Simple. Until this changes, we can change everything else, nothing will get better.
