Australia’s ‘great green boom’ of 2010-11 has been undone by drought

Extreme wet years are getting wetter and more common. This means Australia's terrestrial ecosystems will play a larger role in the global carbon cycle.

Land carbon storage swelled in the Little Ice Age, which bodes ill for the future

When temperatures dipped between 1500 and 1750, the world's landscapes responded by storing more carbon. Now, with temperatures climbing, it's possible they will do the opposite and release even more.

Will the Arctic shift from a carbon sink to a carbon source?

Global warming is changing the movement of carbon within northern ecosystems to the point where the Arctic could become a net source, rather than sink, of greenhouse gas emissions.

Record rains made Australia a giant green global carbon sink

Record-breaking rains triggered so much new growth across Australia that the continent turned into a giant green carbon sink to rival tropical rainforests including the Amazon, our new research shows…

Missing part in carbon budget discovered

While it was previously thought that charcoal remained in the soil where it was formed, a new discovery has been made that…

Bacteria versus virus in oceanic war

The most abundant bacteria on record are also the hosts of the most abundant viruses, a result found by researchers from…

Diamonds show depth of carbon cycle

Diamonds from 700 kilometres below the earth’s surface show the carbon cycle extends deep into the planet’s interior. The…
