The Arctic Sea Ice Outlook has just been updated for July. It”s based on a synthesis of 16 estimates which utilise a range of different projection methods. They note that there is “no indication that a return to historical levels will occur”.
The full range of estimates range from 4.0-5.2 million square kilometers, the record low in 2007 was around 4.3 million square kilometres (2008 was 4.7). Most estimates therefore fall between the record lows in 2007 and 2008, although they do note that:
There appears to be about a 20% chance of reaching a new minimum in 2009.
Arctic Sea Ice Outlook (July)
On the flip-side, based on their estimates there is a 40% chance of sea-ice coverage being greater than 2008 levels. Even more interestingly, depending on which method you select, the chance of 2009 levels setting a new record is between 5-36%...
To quote from the summary:
The two lowest estimates, 4.0 and 4.2 million square kilometers, would represent a new record minimum. All estimates are well online casino below the 1979–2007 September climatological mean value of 6.7 million square kilometers. The uncertainty / error values, from those groups that provided them, are about 0.4 million square kilometers, thus many of the values essentially overlap.
Although the majority of the responses indicate either persistent conditions or a slight increase over the 2008 sea ice extent, there appears to be about a 20% chance of reaching a new minimum in 2009. The September 2009 extent, as we track it for the rest of the summer, will depend on several factors, including the dynamics of the relatively high levels of thin, first year ice; temperature and wind conditions; and sea level pressure.
The report confirms the importance of first-year ice (FYI):
Multi-year sea ice has been reduced to such low levels that the overall September sea ice extent is largely tied to the fate of the first-year sea ice, which appears thin or with low concentrations away from the central Arctic. Depending on August conditions, much of this first-year sea ice could either melt out by September or survive the summer as a vast expanse of thin sea ice.
Accounting for their low 4 million square kilometre estimate, Rignor et al commented that:
In comparison to 2007 and 2008, there is much more first year (FY) ice in the Beaufort and Chukchi Seas in 2009, which we expect to precondition thisarea for a more extensive retreat than in 2007 and 2008.

For thirty years CAT has been at the forefront of understanding environmental issues. Decades before there was an appreciation of the environmental challenges we now face, CAT was educating and informing about their inevitability, carrying our pioneering work into sustainability issues, and formulating practical solutions which are now finding enthusiastic adopters throughout government and business around the world.
Zero Carbon Britain found its inspiration in the 1977 CAT Alternative Energy Strategy – it is a testament to the prescience and integrity of CAT that it was undertaking work in a similar vein to Zero Carbon Britain thirty years ago, and has continued to do so since.
Zero Carbon Britain clearly demonstrates how Britain can escape its current reliance on fossil fuels by adopting key policy frameworks and utilising a carefully balanced spread of renewable technologies. PIRC Development Manager Tim Helweg-Larsen and CAT Development Director Paul Allen coordinated the Zero Carbon Britain research project, leading a team of researchers from CAT’s Graduate School of the Environment, and working closely with key thinkers like Aubrey Meyer and the late David Fleming to include their groundbreaking work in the report.
With enormous input from many different people, and funding from a variety of sources, PIRC’s policy-oriented expertise complemented CAT’s strong research skills. We worked on bridging the divide between climate science, policy and technology, and on integrating, producing and publishing the final
Zero Carbon Britain clearly demonstrates that in an emergency scenario, the reduction of Britain’s current fossil fuel consumption to zero within two decades is an achievable goal. Guided by Contraction and Convergence, the global framework for managing climate change, and using a electronic carbon allowance system, TEQs, to evenly distribute Britain’s carbon budget, the report describes powering down fossil fuel energy and waste, and powering up renewable energy generation. Sector by sector it explores the practical implications of this move towards a climate-safe future: outlining the transport systems we’ll be using, the homes we’ll live in and how industry, food and other sectors will operate.
Zero Carbon Britain has been published at a time when there is a need for clearly mapped out solutions.
Zero Carbon Britain has been published at a time when there is a need for clearly mapped out solutions. By presenting these in a realistic and achievable scenario, CAT and PIRC are at the cutting-edge of focused climate change policy generation, creating groundbreaking research and developing it into effective tools for change.
We are giving a Zero Carbon Britain presentation to the Annual Conference of the Claverton Energy Group, an independent think-tank of renewable energy professionals considering policy and technology solutions for Britain and Europe.
The Sheila McKechnie Foundation has opened applications for its 2008 awards, inspired by the legacy of Dame Sheila McKechnie.

The ESRC”s Research Group on Lifestyles, Values and Environment (RESOLVE) has just published an important initial analysis of the UK”s carbon footprint based on final consumption. From our research on CAT”s Zero Carbon Britain project we”re very aware that further research in this field is casino online sorely needed.
The UK Climate Change Bill proposes to establish legally binding targets for a 60% reduction in carbon dioxide emissions by 2050. This paper discusses the challenges posed by measuring progress towards this target. It takes as a premise that the conventional production-based accounting framework, enshrined in the UNFCCC emissions accounting guidelines, is inappropriate for this task because it fails to account for the carbon
