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

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.

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.

There are a range of associated impacts related to increasing temperatures which affect both evaporation rates and river systems, which are already over stressed, and these will hit farming communities and the health of crop lands.

There was never going to be a right time for a band that was still recording and had health in its environment, had made a very good record and was playing well.

At an everyday level I would reckon myself more than fortunate.

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