Climate change is also clearly a matter of huge interest and concern for the scientific community.

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.

It's absolutely not acceptable for people to argue that, if we are going to do anything about climate change at all, well, the responsibility lies solely with the individual.

There is job growth in renewables, there is job growth in energy efficiency and there is job growth in developing innovative industries and technologies to successfully meet the challenge of climate change.

It is now well understood that humans ultimately depend on the health of the planet for their wellbeing.

Humans remain entirely atmosphere dependent, so there is no choice but to respond to extreme climatic behaviour and its many effects.

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