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.
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.
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.
New satellite data show in unprecedented detail the flow of carbon dioxide into the atmosphere. We might soon have signatures of individual power stations.
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.
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.
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.
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.
