It depends on what you mean by 'peace'

Soviet ideology defined 'peace' as submission to the Soviet Union.

Islamist ideology defines 'peace' as submission to Islam.

So, in that sense, I guess it makes sense that Al Gore won the Nobel 'Peace' Prize. As chief ideologue of the radical environmental left, Gore has told us in many ways that 'peace' is submission to the views and prescriptions of the CoGW.

Discerning folks (defined as those with more than a smidgen of common sense) know that the Nobel Peace Prize has long been a vehicle for the promotion of leftist ideology. The awarding of the prize to unrepentant terror leader Yasser Arafat back in the 90s should have removed all doubt about that.

The October 12 AP article linked above shows that the Nobel committee does not even pretend to honor Alfred Nobel's intention for the peace prize:

In recent years, the Norwegian committee has broadened its interpretation of peacemaking and disarmament efforts outlined by Swedish industrialist Alfred Nobel in creating the prize with his 1895 will. The prize now often also recognizes human rights, democracy, elimination of poverty, sharing resources and the environment.

Satirist Scott Ott added his own spin to the news:

Mr. Gore could not be reached for comment as he was returning from Oslo, Norway, in a private jet. However, his spokesman said that his efforts to bring peace on earth speak for themselves.

“Thanks to Al Gore’s movies, speeches and books,” said the unnamed spokesman, “Terrorists and tyrants around the world will soon lay aside the weapons of war and give peace a chance by working together to develop a hybrid car that runs on cheap, clean-burning gunpowder.”

With this gargantuan boost to Gore's ego, we can be sure that we won't be getting any peace from him any time soon.
