WCRP newsletter available featuring Grand Challenge Report and Polar CORDEX activity

The December 2013 issue of WCRP E-zine, n. 27, is now available, Click here to download the pdf version. This issue features the report of the workshop convened by WCRP/CliC in October 2013 to further develop the strategy to address the WCRP Cryosphere in a Changing Climate Grand Challenge. The report serves to frame the outcomes and future actions to move forwards like the Polar CORDEX activity.

Video lecture by Peter Lemke: Polar regions under climate change

CliC Scientific Steering Group member Peter Lemke talks about how climate change is impacting the cryosphere, and his experiences and new findings from a recent expedition to the Antarctic.
View the public lecture, third in a joint series by IIASA and the Austrian Academy of Sciences, on YouTube or in the CliC Media Gallery.

Abstract Deadline Extended for DUE Permafrost Workshop

The Abstract Submission Deadline for the CliC GTN-P ESA DUE Permafrost Workshop has been extended to 20 December.

The workshop objective is to bring together the scientific permafrost communities and the producers of satellite data. The 4th DUE Permafrost User Workshop will be held at ESA ESRIN, Frascati, Italy the 11-13 February 2014. It is sponsored by the Climate and Cryosphere Project (CliC) and Global Terrestrial Network for Permafrost of the International Permafrost Association (GTN-P/IPA) and the European Space Agency (ESA).

Important Dates:
DEADLINE FOR ABSTRACTS IS 20 DEC 2013 ** Extended**
DEADLINE FOR REGISTRATION IS 15 JAN 2013

The deadline for applications for funding support has past. Decisions are still pending. Applicants will hopefully be informed of decisions before the holidays.

This CliC GTNP ESA DUE Permafrost workshop

• will bring together a multidisciplinary community working on permafrost-related remote sensing, field monitoring and permafrost-related modelling and climate modeling.
• will collect and discuss the up-to-date User requirements, validation approaches and the broadening range of applications.
• will contribute to the update of the IGOS Cryosphere Theme Report (2007) for permafrost.
• will feed into current efforts of GTN-P to build a permafrost observing component into the Sustaining Arctic Observing Network (SAON).

This meeting is open to all who are interested in attending. There will be no registration fee. Participants are invited to submit an abstract for an oral presentation or a poster.

The workshop is jointly organized by CliC, ESA, and members of the former DUE permafrost team, Birgit Heim (AWI, DE), Annett Bartsch (APRI,AT & LMU, DE), Claude Duguay (UW, CA) Jenny Baseman (CliC), Vladimir Romanovsky (IPA/GTN-P) and Frank-Martin Seifert (ESA).

Circumpolar Assessment of Permafrost Carbon Quality Publication Available

A new publication from the CliC sponsored Permafrost Carbon Research Network is available.

Schädel, C., Schuur, E. A. G., Bracho, R., Elberling, B., Knoblauch, C., Lee, H., Luo, Y., Shaver, G. R. and Turetsky, M. R. (2013), Circumpolar assessment of permafrost C quality and its vulnerability over time using long-term incubation data. Global Change Biology. doi: 10.1111/gcb.12417

High-latitude ecosystems store approximately 1700 Pg of soil carbon (C), which is twice as much C as is currently contained in the atmosphere. Permafrost thaw and subsequent microbial decomposition of permafrost organic matter could add large amounts of C to the atmosphere, thereby influencing the global C cycle. The rates at which C is being released from the permafrost zone at different soil depths and across different physiographic regions are poorly understood but crucial in understanding future changes in permafrost C storage with climate change. We assessed the inherent decomposability of C from the permafrost zone by assembling a database of long-term (>1 year) aerobic soil incubations from 121 individual samples from 23 high-latitude ecosystems located across the northern circumpolar permafrost zone. Using a three-pool (i.e., fast, slow and passive) decomposition model, we estimated pool sizes for C fractions with different turnover times and their inherent decomposition rates using a reference temperature of 5 °C. Fast cycling C accounted for less than 5% of all C in both organic and mineral soils whereas the pool size of slow cycling C increased with C : N. Turnover time at 5 °C of fast cycling C typically was below 1 year, between 5 and 15 years for slow turning over C, and more than 500 years for passive C. We project that between 20 and 90% of the organic C could potentially be mineralized to CO2 within 50 incubation years at a constant temperature of 5 °C, with vulnerability to loss increasing in soils with higher C : N. These results demonstrate the variation in the vulnerability of C stored in permafrost soils based on inherent differences in organic matter decomposability, and point toward C : N as an index of decomposability that has the potential to be used to scale permafrost C loss across landscapes.

Final report of the Future Earth Transition Team Published

- CliC is a core project affiliated with Future Earth

Future Earth has just published the final report of the Transition Team, the group of experts that led the initial design of the research initiative on global sustainability.
 
The team comprised seventeen members from a wide range of disciplines and countries, and also included ex-officio members representing the main partners of the Science and Technology Alliance for Global Sustainability.
 
Co-chaired by Johan Rockström and Diana Liverman, the team proposed a vision for integrated and solutions-oriented research that can support a transformation towards global sustainability over the coming decade. The report sets out the initial design of Future Earth, comprising a research framework and governance structure, preliminary reflections on communication and engagement, capacity-building and education strategies, and implementation guidelines.
 
Structuring the research agenda around three central themes – dynamic planet; global development; transformations towards sustainability – the report details the key research questions that will be addressed in each area. At its core lies a new partnership between science and society to co-design research priorities and co-produce knowledge.
