Buried treasure

ReportageOver the entire 800,000-year record, atmospheric carbon dioxide has never peaked over 300 ppm. For all of human history, it sat around 275 ppm until about 200 years ago, when we began to dig up and burn coal to fuel the Industrial Age. In 1950, it punched through the 300-ppm historic ceiling. In mid-May, as the forests of the Northern Hemisphere dropped their leaves, the planet exhaled atmospheric carbon dioxide at a new daily record of 421 ppm.

Across the Bass Strait

FictionMum was sitting by herself on a bench attached to the wall of the ship under a Perspex roof. We sat next to her holding on to the bottom of the bench. I told Mum that I had been sick and she wiped my forehead and cheek and said, 'I'm sorry. I'm so sorry,' and it looked like she was crying. She said it was just the sea spray and the cold. And it was cold. It was freezing and the wind cut into my back like I had no skin at all. I could hear the water crack against the ship, feel it hit then hear the spray shoot up. Only I couldn't see it. I couldn't see anything past the light cast out on the deck. Out there the world was raging in the blackness.
