The idea that the growing demand for energy worldwide can be met with energy from nuclear power is nonsense.

My office has a view of low-cost housing, old East German prefabricated apartment buildings. It isn't an attractive view, but it's very helpful, because it reminds me to ask myself, whenever there is a decision to be made, whether the people who live there can afford our decisions.

Those who reject integration programs in the long term have as little right to stay in Germany as a hate preacher paid from abroad in a mosque.

However, I have a low opinion of people with narrow political horizons. Someone who talks about the environment and knows nothing about economics can make as many mistakes as someone who does the opposite.

We just love international music. We love the climate of that sound, it's that pulse that we just have to appreciate.

It really gets on my goat that people keep quoting Dorothea Mackellar's 'My Country' as proof that there is no such thing as climate change. A poem written more than 100 years ago by a homesick 19 year old versus an ever-increasing body of refereed scientific thought... hmm, hard to know which way to jump, really.

The only thing that will really change global warming in the long run is if we radically increase the speed with which we get alternative technologies to deal with climate change.
