As a software developer with a keen interest in the future of humanity, I have created this web site as a service to the community, to promote greater understanding and cooperation in responding to the unprecedented challenge of anthropogenic climate change.

I am not a member of any political party and I comment on the policies of Australia's political parties on their merits. I have been writing on climate change since 1997.

The reason I care is that the future of billions of people really is at stake. A rise in temperatures by 4 degrees C by the end of the century must be avoided. Otherwise, the tropics will become too hot for habitation, sea levels will rise by several metres, and famine and war will follow. Up to 2 billion people could become refugees.

We are complacent about the 0.8 degrees C rise already experienced, not realising that the science predicts a delay between cause and effect. By the time governments find the will to act in the interest of the planet rather than their own little kingdoms, it may well be too late.
