What has Gore done for peace?
Yes, climate change is certainly a war and peace issue, but it was on the international agenda before Gore started to occupy the theme.
To prioritize this years prize on climate change is fine. But R K Pachauri and the United Nations Intergovernmental Panel on Climate Change alone would have been better in emphazising the global challenge. Gore’s prize makes this an U.S. centric theme.
More in general: Can’t we think of people who have done more – and sacrificed for peace.
Best guess for the motive:
The committee wanted to give Gore a push to run for U.S. president. Maybe not a bad idea, but why (again) demean the peace prize for it. Anyway, may he live up to it.
