There is yet another new PAGE21 related publication "Land surface temperature retrieval over circumpolar Arctic using SSM/I–SSMIS and MODIS data" authored by Cyrille André and Catherine Ottlé from CEA together with A. Royerb and F. Maignana from Université de Sherbrooke, Canada.
The paper presents how the researchers combine passive microwave and thermal infrared data to estimate land surface temperature during summer snow-free periods over northern high latitudes.
The paper was published in "Remote Sensing of Environment" and is accessible freely on the RSE journal website until 12 April here.

Printed as a special issue of the IASC yearbook, the publication compiles and analyzes the history and development of IASC and its initiatives and achievements. A collection of historical documents, a film and a brochure presenting a timeline of the most important events in the development of IASC in the last quarter of a century complement the publication.
Printed copies of the publication will be available at the Arctic Science Summit Week (ASSW) 2015 in Toyama, Japan. www.assw2015.org

Nature Geoscience just newly published a PAGE21 related paper called "Net regional methane sink in High Arctic soils of northeast Greenland" authored by Christian Juncher Jørgensen, Katrine Maria Lund Johansen, Andreas Westergaard-Nielsen and Bo Elberling from the University of Copenhagen.
This paper presents measurements of rates of methane consumption in different vegetation types within the Zackenberg Valley in northeast Greenland over a full growing season.
Based on these measurementthe authors conclude that the ice-free area of northeast Greenland acts as a net sink of atmospheric methane, and suggest that this sink will probably be enhanced under future warmer climatic conditions.

Arctic Change 2014 Conference took place last week, 8 – 12 of December in Ottawa, capital city of Canada.
Climate change and Arctic issues, including the health of Northerners, melting sea-ice, intercontinental shipping, resource exploration, and the expansion of national jurisdictions, are moving to the top of national and international agendas.
Circumpolar nations face an increased urgency to expand the observational basis needed to formulate strategies and policies that will minimize the negative impacts and maximize the positive outcomes of the on-going transformation of the Arctic.
Building on the success of its annual scientific meeting, the ArcticNet Network of Centres of Excellence and its national and international partners welcomed the international Arctic research community to Ottawa for the International Arctic Change 2014 Conference.
Coinciding with the pinnacle of Canada's Chairmanship of the Arctic Council, Arctic Change 2014 welcomed the participation of international researchers, students, policy and decision makers, representatives of government and non-government organisations, the private sector, northern stakeholders and media to address the global challenges and opportunities arising from climate change and modernisation in the circum-Arctic.
With over 1000 participants expected to attend, Arctic Change 2014 was one of the largest trans-sectoral international Arctic research conference ever held in Canada.

The Symposium on ´´The evolution of mountain permafrost´´ will take place in Sion, Switzerland 4th – 7th February 2015.
The Symposium acts partly as final symposium of the inter-disciplinary TEMPS-project (The evolution of mountain permafrost in Switzerland) funded by the Swiss National Science Foundation.
The main objective of TEMPS and the above symposium is an improved understanding of the vulnerability of mountain regions to permafrost changes and to assess the current and future impacts on populated mountain regions such as the European Alps.
The 2-day symposium will include invited lectures on mountain permafrost research, the presentation of the main project results, and a specific practitioner's day (German/French) to strengthen the relation between science and practice.
All permafrost-interested practitioners and scientists are cordially invited to join the symposium.
for more information about the Symposium.
