focus on the challenges posed by water in a warming world. Happy
Christmas to all and here's to a great 2013.
21st December 2012 Closing
Joeri Rogelj and colleagues at the Institute for Atmospheric and
Climate Science have shown the emissions reduction needed by 2020
to avoid 2 degrees C of warming.
22nd November 2012 Growing
The World Meteorological Office has confirmed that concentrations
of carbon dioxide, methane and nitrous oxide all rose to new highs
in 2011. Carbon dioxide concentrations reached 391ppm.
22nd November 2012 European
The European Environment Agency has assessed the past and projected
impacts of climate change in Europe, warning that impacts will
become more severe with the costs of damage rising.
22nd November 2012 Emissions
The UN Environment Programme has highlighted the large gap between
actual greenhouse gas emissions and the level required to avoid
post-industrial global warming of 2 degrees C.
29th October 2012 Rice
Kees Jan van Groeningen of Trinity College Dublin and colleagues
in the US, have projected an increase in methane emissions from
rice cultivation in response to future climate change.
22nd September 2012 Low
The US National Snow and Ice Research Center has reported that
the extent of Arctic sea ice has reached a record low. In September
the extent dropped to 50% of the 1979-2000 average.
17th August 2012 People
Nature Climate Change has highlighted the barriers to successful
action on climate change arising from a paucity of information
on individual and societal responses.
17th August 2012 Drought
Aiguo Dai of the National Center for Atmospheric Research in Colorado,
USA, has shown that trends in drought since 1950 support projections
of widespread drought in the 21st century.
12th July 2012 Medieval
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
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
Michelle van Vliet of Wagningen University, and colleagues, have
revealed the risk climate change poses to power generation from
thermal power plants in the US and Europe.
13th June 2012 Carbon
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
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
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
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
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
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
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
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
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
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
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 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
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
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
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.
26th January 2012 Bog
Dong Liu and colleagues at Zhejiang University in China have estimated
that the use of constructed wetlands to grow biofuels could replace
6.7 percent of national gasoline consumption.
7th January 2012 Carbon
Global carbon dioxide concentrations rose by just over 2ppm in
2011, while global temperatures were around 0.5 degrees C higher
than the 1951-1980 global average.
7th January 2012 Happy
Wishing everyone a very happy New Year and here's to a great 2012.
This year sees the landmark Rio+20 conference, plus real potential
for progress on a global climate agreement.
