Towards a new view of sustainable development: human well-being and environmental stress — Last modified July 21, 2014 10:48
The finding that emissions are decoupled from increased well-being is not only of scientific interest, it could also inform policy discussions, say Thomas Dietz and Andrew K Jorgenson.
Why we can halve fertilizer use — Last modified July 21, 2014 09:15
When it comes to fertilizing crops, many farmers take the attitude that too much fertilizer is better than too little. But unfortunately this excess fertilizer has negative consequences for the environment, impacting water quality, air quality, climate and ecosystem health. A new study reveals that fertilizer use could be halved without any loss in global food production. Meanwhile, food production could be increased by around one third if the excess fertilizer was redistributed and applied to nitrogen-poor soils.
Smithsonian scientists find that vines choke a forest's ability to capture carbon — Last modified June 11, 2014 09:16
Tropical forests are a sometimes underappreciated asset in the battle against climate change. They cover 7% of land surface yet hold more than 30% of Earth's terrestrial carbon. As abandoned agricultural land in the tropics is taken over by forests, scientists expect these new forests to mop up industrial quantities of atmospheric carbon. New research by Smithsonian scientists shows increasingly abundant vines could hamper this potential and may even cause tropical forests to lose carbon.
New research shows humans have more impact on tropical nitrogen levels — Last modified May 30, 2014 07:56
A new paper co-written by four University of Montana researchers finds that humans have more than doubled tropical nitrogen inputs.
How did Australian drylands cause record land carbon sink in 2011? — Last modified May 30, 2014 07:53
Each year, scientists assess how much carbon the ocean, land and atmosphere absorbed. In 2011 land took up the largest amount of carbon since measurements began in 1958 – 4.1 Petagrammes (Pg) compared with the decadal average of 2.6 Pg. Now an international team has discovered that the bulk of this uptake was due to plant growth in dry regions of the southern hemisphere, particularly Australia.

Scientists unmask the climate uncertainty monster — Last modified April 14, 2014 08:56
Increasing uncertainty in the climate system compels a greater urgency for climate change mitigation, according to new research from the University of Bristol.
Amazon inhales more carbon than it emits — Last modified March 25, 2014 15:30
A new study led by NASA and the University of Leeds has confirmed that natural forests in the Amazon remove more carbon dioxide from the atmosphere than they emit.
