Scientists and economists issue urgent warning that $4bn plan is not improving basin health

A group of prominent scientists and economists has issued a stark warning to the nation’s politicians: the Murray-Darling basin plan is failing to achieve environmental goals and is a “gross waste” of money.

The group of seven economists and five scientists with deep expertise in the river are meeting on Monday morning in Adelaide to issue what they are calling the Murray-Darling declaration.

It’s a simple idea: strip CO2 from the air and use it to produce carbon-neutral fuel. But can it work on an industrial scale?

It’s nothing much to look at, but the tangle of pipes, pumps, tanks, reactors, chimneys and ducts on a messy industrial estate outside the logging town of Squamish in western Canada could just provide the fix to stop the world tipping into runaway climate change and substitute dwindling supplies of conventional fuel.

It could also make Harvard superstar physicist David Keith, Microsoft co-founder Bill Gates and oil sands magnate Norman Murray Edwards more money than they could ever dream of.

Concessional $900m loan cannot proceed without Queensland government approval, Karen Andrews says

The Adani Carmichael coalmine will not receive federal funding from the Northern Australia Infrastructure Facility for a vital rail line, a Turnbull government minister has said.

The announcement by Karen Andrews on Sunday is a major blow to Adani, which has sought a $900m concessional loan for rail to link the Carmichael mine to port – and could spell the end of the project entirely if it can’t secure private finance.

Boduan, Pwllheli: A woodland burial reminds us that nature is the mirror and foundation for every resurrection myth

My dear old friend loved birds. They brought her joy. I’d spent many peaceful hours in her garden room, keeping her company, watching the nuthatches, woodpeckers, goldfinches and siskins at her bird table during these recent years of illness patiently borne. She died in the last minutes of the old year, at the age of 88. A woodland burial was arranged at Boduan Sanctuary. Waxy-white clumps of snowdrops reflected in the hearse’s paintwork as she left her home for the last time.

At the sanctuary wood’s car park we lifted her into a sturdy rustic cart with iron-rimmed wheels. On the narrow path into the wood, one of these ran over my foot. I imagined the quip this lively, humorous woman would have lanced my way, and changed position to push from the back. We held straps to lower her into the grave, and as we did so the sun’s barred rays threaded through the trees, traversed her wicker coffin, and illuminated the moss and the pale trunks of the silver birches.
