Tim Lenton, of the University of Exeter, UK, has shown that, in principle, early warning predictions of climate 'tipping points' like dieback of the Amazon rainforest may be possible.

Brendan Fisher and colleagues at the University of East Anglia, UK, have provided an updated estimate of the implementation and opportunity costs of reducing deforestation in Tanzania.


ice web 2nd June 2011 Arctic Openings
Scott Stevenson and colleagues at the University of California have modelled the impacts of climate warming on ice loss, snow fall, permafrost stability and human access to the Arctic.

The UN's Intergovernmental Panel on Climate Change (IPCC) has released a new report forecasting the potential changes in global energy mix over the next four decades.


eggs 16th May 2011 Laden Bin
A report commissioned by the United Nations food agency has revealed that around one third of the world's food is currently wasted - equivalent to 1 billion tonnes every year.


crop 25th April 2011 Biofuel Albedo
Scott Loarie and colleagues at Stanford University, USA, have reported that sugar-cane biofuel expansion into agricultural lands in Brazil can result in a direct net cooling effect.


shags 20th April 2011 Antarctic Warming
Qinghua Ding and colleagues at the University of Washington, US, have shown that the Pacific sector of Antarctica has warmed substantially in the last thirty years.


flood 24th March 2011 Lake Outbursts
Gino Casassa of the Center for Scientific Studies (CECS) in Valdivia, Chile, has warned of the trend of increasingly frequent glacial lake outbursts resulting from climate change.


flame 24th March 2011 Black Rain
Yun Qian and colleagues in Washington have revealed that black carbon and dust deposition are having a greater effect on snow cover in Tibet than warming due to the enhanced greenhouse effect.


ice sheet 17th March 2011 Albedo Drop
Mark Flanner of the University of Michigan, and colleagues, have revealed the extent of additional climate forcing caused by the loss of snow and sea ice cover in the Northern Hemisphere.


UK coast 17th March 2011 Islay Initiative
Scottish Power and the Scottish Government have announced the development of the world's largest tidal power energy scheme. The 10 megawatt project will be in the Sound of Islay.


pc 2nd March 2011 Carbon Counting
Preliminary estimates of the change in global carbon dioxide concentrations in 2010 indicate the increase was the largest since 1998. Average concentrations are now 390ppm.


clouds 21st February 2011 Climate Fingerprinting
Gabi Hegerl of the University of Edinburgh, and colleagues, have confirmed the link between greenhouse gas emissions and increased rainfall in the Northern Hemisphere.


trees 21st February 2011 Shape Shifting
Brian Enquist and colleagues at the University of Arizona have suggested that climate change could reshape the structure of tropical forests and the cycling of carbon within them.


Auracaria tree 6th February 2011 Thirsty Amazon
Simon Lewis and colleagues at the Unversity of Leeds, UK, have warned that droughts in the Amazon, such as that seen in 2010, threaten to weaken the carbon dioxide sink.


leaves 6th February 2011 Green Shoots
The UN Food and Agriculture Organisation has reported that the rate of global forest loss slowed between 2000 and 2010, mainly as a result of more tree planting in Asia.


penguins 21st January 2011 Warmest Years
