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.

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

Climate change is such a huge issue that it requires strong, concerted, consistent and enduring action by governments.

Well I'm not convinced that expanding uranium mining is in the best interests of the country and the best interests of its environment.

The Capitol was an occasion where you arrive at a sign in the road that says you have arrived at a place you may not have expected to be, but you know how you got here: Next!

Climate change is so big that people who study it.. and many do.. need to speak to it. They must present scientific papers, they must appear in public, they must speak to the media and we must hear their voices. In order to get policy right, policymakers.. governments.. need to make decisions based on sound science.

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