This is a personal blog to explore and share ideas related to climate change, sustainable development and public health. From the start my aim has been to be both honest and optimistic about these issues. For me they are the most challenging and most important of our time. They demand action on an unprecedented scale and as such give us the greatest opportunity we have ever had to create a better healthier fairer world. I have decided that this is the most valuable thing I can spend my life working on. I have called the blog “Our Greatest Opportunity” because of this.

If this blog inspires greater dialogue and more positive action that would be wonderful.

All the views expressed here are mine and should not be associated with any of the organisations with which I may be working.  I would value constructive comments on the blog.
