Dry period in semi-arid central Australia.
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.
Forests and other land-based carbon stores held onto more carbon during colder historical climates.
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.

Since 1999, Australia has swung between drought and deluge with surprising speed, because El Niño has fallen into sync with similar patterns in the Indian and Southern Oceans.
The warming global climate is causing fundamental changes to the carbon cycle in northern parts of the world.
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.

Plans to store more carbon in French soil could have a massive impact on the country's emissions – if they can pull it off.
Dr Mike Raupach died earlier this week after a brief illness. He passed away peacefully at home with his family in Canberra, Australia. He was 64. Mike was a brilliant and outstanding scientist. He was…
We were doing just fine before the oceans got involved.

It’s well known that carbon in the atmosphere is causing global warming. What is less well known, outside of scientific circles at least, is the role oceans have to play in this. Our seas contain 60 times…
Lush rainforest above ground… spare a thought for what’s happening in the soil.
It’s no exaggeration to say the tropics drive our planet’s carbon cycle – the constant transfer of carbon back and forth, on a global scale, between living things and the environment. Understanding the…

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…
Coal is still driving the world’s carbon emissions up.
Growth in global carbon emissions is slowing, but is still more than enough to increase global temperatures by more than…
