12th July 2012 Medieval Warming
Jan Esper and colleagues at Johannes Gutenberg University, Germany, have found new evidence that suggests that temperatures in the Medieval period have been underestimated.

 

13th June 2012 Oceanic Fingerprint
Peter Glecker, of the Lawrence Livermore National Laboraory, USA, and colleagues have strengthened the evidence for attribution of recent oceanic warming to human activities.

 

13th June 2012 Climate Feedback

13th June 2012 Carbon Sponge
Martin Schroder at Nottingham University, UK, and colleagues have developed a novel material that is able to soak up carbon dioxide under pressure and then retain it at low pressures.

 

22nd May 2012 Energy Bill
The UK Government has announced its draft Energy Bill. Included is big financial support for nuclear and renewable energy, but there is no firm commitment to phase out fossil fuels by 2030.

 

14th May 2012 Food For Thought
Dave Reay, of Edinburgh University and GHGonline, and colleagues in Europe and the US have estimated the large greenhouse gas emissions cuts made possible by reducing food waste.

 

25th April 2012 Corn and Climate Change
Noah Diffenbaugh and colleagues at Stanford University have found that corn prices in the US are made even more sensitive to climate change impacts by binding biofuel targets.

 

25th April 2012 Cut and Thrust
The Brazilian Chamber of Deputies has delayed a crucial vote on legislation to determine the proportion of forested land that must be preserved as agricultural land use expands.

 

28th March 2012 Climate Smart Food
Sir John Beddington and colleagues have called for an increase in 'Climate Smart Agriculture' to help provide food security and reduce greenhouse gas emissions in the coming decades.

 

28th March 2012 Pushing the Envelope
Myles Allen, of Oxford University, UK, and colleagues have released findings from recent climate simulations that suggest global temperatures could rise by 3 degrees C by 2050.

 

28th March 2012 Cooler Costas
Fredrik Boberg and Jens Christensen, of the Danish Met Institute, have reported that some regional climate change model projections overestimate the extent of warming.

 

2nd March 2012 Nordhaus Responds
William Nordhaus, an economist at Yale Univiersity, US, has responded to climate change skeptics on six key issues - including the economic impacts - that are frequently raised by them.

 

2nd March 2012 Waste Water Power
Bruce Logan and colleagues at Pennsylvania State University have constructed a device that can generate electricity from waste water. It is hoped the device will provide clean water and power.

 

2nd March 2012 More Midges
Matthew Bayliss and colleagues at the University of Liverpool, UK, have predicted that climate change in the UK risks increasing the spread of vector-borne diseases.

 

22nd February 2012 Altered Amazon
Ahead of the Rio plus 20 meeting in June, Eric Davidson and colleagues at the Woods Hole Research Center, USA, assess the changing carbon fluxes in the Amazon basin.

 

14th February 2012 Sky's the Limit
The Chinese authorities have barred all airlines from joining the European Union Emissions Trading Scheme. China claims the scheme would cost its airlines almost £80 million each year.

 

14th February 2012 Algal Alterations
Stephanie Hinder and colleagues at Swansea University, UK, have reported that algal community composition has altered due to increasing sea temperatures and windier summer weather.

 

26th January 2012 Hotter Summers
The UK's Department of Environment and Rural Affairs (Defra) has released its first full assessment of the risks and opportunities of climate change in the UK during the 21st century.

 

26th January 2012 Sow and Reap
Julia Pongratz and colleagues at Stanford University in the US have suggested that geoengineering of the climate using solar radiation management may result in increased crop yields.
