But no matter how big the effort to push a propaganda line might be, climate change is bigger. This, undoubtedly and regrettably, is the biggest immediate long-term environmental challenge we face. A failure to concretely come to some policy outcome on climate change has not only a negative environmental impact but also social and economic consequences for us.

That was the crossover line for us, to be able to play that many shows, sell them out real quick and have that tribe queue up outside and still be a mystery to everybody else.

Look, very clearly there are things that need to be done urgently in relation to climate change, and of those the most obvious is to have an enforceable and equitable arrangement delivering deep cuts in emissions into the middle of the century.

The place where the system and people's intentions meet is the political arena.

The Pro-Life cause is the preeminent cause of our time, and this struggle between the gospel of life and the culture of death will determine the destiny of mankind.

I guess for me what is more significant than success is the nature of each of the songs and of the words.

I believe that the quantum of our knowledge will increase considerably in the coming years and that scientists will continue to be amongst the brave voices speaking out.
