Yet however comforting and peaceful beach-combing is, it ends up like the sea, as disturbing as it is reassuring. In dark moments I believe that walking on a beach at low tide is to be looking for death, or at least anticipating it. You will only find the dead, the spilled and the cast-off. Things torn free of their life or their place.

Nothing is as daunting as the threats associated with global warming. That's the biggie. Everyone bangs on about rising sea levels but the real challenge of a warming planet is ocean acidification. An acid ocean spells the end of life on earth.

And the sun on the wall of her room, the block of sun with all the tiny flying things in it. When she was little she thought they were the souls of dead insects, still buzzing in the light.

The notion that love is abroad in the world has shaped my life.

I don't consciously watch and file lived moments for my work. I have a couple of writer friends who do that and it creeps me out, to be honest. I know people think I must do that too, but I don't. But I do have a long memory.

Australia was once a leader in taking global warming seriously. The former PM [Kevin Rudd] called it 'greatest moral challenge of our time'. But in the past couple of years the national consensus has been eroded and Australians are being encouraged by the polluters and their mates in Parliament to forget it was ever mentioned. It's heartbreaking.

It's sadness coming on like the old days, the vast seamless hopeless weight of sadness looking for a place to rest.
