Laboratory in the US have reported initial success in using microbial

18th July 2011 Tipping
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.

released a new report forecasting the potential changes in global
energy mix over the next four decades.

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.
25th April 2011 Biofuel
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.
20th April 2011 Antarctic
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.
24th March 2011 Lake
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.
24th March 2011 Black
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.
17th March 2011 Albedo
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.
17th March 2011 Islay
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.

threaten to weaken the carbon dioxide sink.
6th February 2011 Green
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.
