Why renting, rather than buying, carbon might help mitigate climate change
To mitigate climate change we might have to re-examine the rules which define carbon credit-worthy sequestration actions – that might include renting, rather than buying.
The upside of blackwater river flows
There’s an upside to the carbon-rich, black water that sometimes flows off the floodplains and into the rivers of the Murray–Darling Basin.
Carbon central to a new wave of climate modelling
Simulating the Earth’s myriad physical, chemical and biological processes is a big ask. But it must be done if we are to work out how what we do today will change the future climate. Thanks to this Australian ‘earth system model’, we’re getting a clearer picture of what’s ahead.
Satellites are giving us a commanding view of Earth’s carbon cycle
New satellite data show in unprecedented detail the flow of carbon dioxide into the atmosphere. We might soon have signatures of individual power stations.
Rising carbon dioxide is making the world’s plants more water-wise
The globe is greening as plants grow faster in response to rising carbon dioxide. But a new analysis shows they aren't using more water to do it - a rare piece of good news for our changing planet.
The kings of carbon capture
Trees are good at sequestering carbon but fire can quickly undo all the good. One place where plants can sequester carbon without fear of fire is under water.
Forty years of measuring the world’s cleanest air reveals human fingerprints on the atmosphere
This year marks the 40th anniversary of Cape Grim, one of only three World Meteorological Organization global super-stations for measuring carbon dioxide - it started in 1976 with an ex-NASA caravan.
A new spin on ocean eddies and marine primary production
Our understanding of the ocean’s biological pump, and the capacity of the ocean to sequester carbon dioxide, has been enhanced by a new study examining ocean eddies.
