I think people need to see the full interview compared to the cherry-picked one in Investor's Business Daily. It can be accessed here:

Note the first sentence in Edenhofer's response (below), which by itself provides a great deal of context: 

Interviewer: De facto, this means an expropriation of the countries with natural resources. This leads to a very different development from that which has been triggered by development policy.

Ottmar Edenhofer: First of all, developed countries have basically expropriated the atmosphere of the world community. But one must say clearly that we redistribute de facto the world’s wealth by climate policy. Obviously, the owners of coal and oil will not be enthusiastic about this.
