PALSEA 2013 Workshop: Estimating rates and sources of sea-level change during past warm periods

The workshop will take place on October 21-24 (25) 2013 at the Istituto Nazionale di Geofisica e Vulcanologia (INGV), in Rome, Italy, and is sponsored by the WCRP Climate and Cryosphere (CliC) Project Office, Past Global Changes (PAGES) and International Union for Quaternary Research (INQUA).

The aim of this workshop is to explore, discuss, and debate what the paleo record can say about rates, sources, and processes of sea-level change across a range of magnitudes and timescales during past warm periods such as the Holocene, the last interglacial period, other interglacial periods such as marine isotope stage 11, and the Pliocene optimum. We encourage diverse contributions such as evidence from geologic records, geochronological controls, and models of climate, ice sheets and glacial isostatic effects. For meeting flyer go to: http://people.oregonstate.edu/~carlsand/PALSEA2/PALSEA_2013_Meeting_files/PALSEA2_2013_circular.pdf

The deadline for submitting abstracts will be 15 June 2013 to , workshop homepage at: http://people.oregonstate.edu/~carlsand/PALSEA2/PALSEA_2013_Meeting.html

Nature Article on Ice-sheet Mass Balance and Climate Change

Since the 2007 Intergovernmental Panel on Climate Change Fourth Assessment Report, new observations of ice-sheet mass balance and improved computer simulations of ice-sheet response to continuing climate change have been published. Whereas Greenland is losing ice mass at an increasing pace, current Antarctic ice loss is likely to be less than some recently published estimates. It remains unclear whether East Antarctica has been gaining or losing ice mass over the past 20 years, and uncertainties in ice-mass change for West Antarctica and the Antarctic Peninsula remain large. We discuss the past six years of progress and examine the key problems that remain. Download the article.

The work presented here is based on the Ice-Sheet Mass Balance and Sea Level (ISMASS) workshop that was held in Portland, Oregon, USA, on 14 July 2012. This workshop was jointly organized by the Scientific Committee on Antarctic Research (SCAR), the International Arctic Science Committee (IASC) and the Word Climate Research Programme (WCRP), and was co-sponsored by the International Council for Science (ICSU), SCAR, IASC, WCRP, the International Glaciological Society (IGS) and the International Association of Cryospheric Sciences (IACS), with support fromClimate and Cryosphere (CliC) and the Association of Polar Early Career Scientists (APECS).

WCRP Special Workshop on Climatic Effects of Ozone Depletion in the Southern Hemisphere Report Available

Contributed by Marilyn Raphael, UCLA

A WCRP Special Workshop on the ‘Climatic Effects of Ozone Depletion in the Southern Hemisphere: Assessing the evidence and identifying gaps in the current knowledge’, was convened at the Pontificia Universidad Católica Argentina, Buenos Aires, Argentina, from 25 February to 1 March, 2013.

The WCRP Special Workshop was held to examine our understanding of the links between stratospheric ozone depletion and recovery and the climate of the Southern Hemisphere including the Southern Ocean. Our understanding of the influence of increasing greenhouse gas concentration was also examined. Of immediate relevance to the CliC community is the discussion of the links between observed changes in the atmospheric circulation due to stratospheric ozone depletion and contemporary Antarctic surface temperature and sea ice trends.  While the links to surface temperature changes in regions such as the Peninsula are clear, those to sea ice changes are not. The discrepancy between the modeled and observed sea ice trends was highlighted as an area for future research with specific reference to the need for a better understanding of sea ice formation processes and the interaction with the ocean and atmosphere.

Permafrost Carbon Network May 2013 Meeting Report Available

The Permafrost Carbon Network held its fifth workshop on Captiva Island, Florida on 16- 17 May, 2013. This workshop included members of the steering committee as well as leads and co-leads of each working group. The purpose of this meeting was to present and discuss progress on synthesis activities, link findings of products from individual working groups into cross-group synthesis activities and to discuss network related items such as data organization or authorship. The CliC project provided travel support for several key international participants to this workshop. Presentations from the workshop are also available on the workshop webpage. Download the Report

The overall objective of the Vulnerability of Permafrost Carbon Research Coordination Network (RCN) (http://www.permafrostcarbon.org/) is to link biological carbon (C) cycle research with well-developed networks in the physical sciences focused on the thermal state of permafrost. This interconnection is being used to produce new knowledge through research synthesis that can be used to quantify the role of permafrost C in driving climate change in the 21st century and beyond. This is achieved by synthesizing information in a format that can be assimilated by biospheric and climate models, and that will be contributed to future assessments of the Intergovernmental Panel on Climate Change (IPCC). Our ongoing activities to reach this goal are: 1) organization of an interrelated sequence of meetings and working groups designed to synthesize existing permafrost C research, and 2) formation of a consortium of interconnected researchers to disseminate synthesis results about permafrost C to other scientific networks and activities. These two research coordination activities are aimed at developing and disseminating algorithms that encapsulate the new process knowledge and datasets in support of model development.

WCRP Data Advisory Council Meeting Report Available

The WDAC 2 report summarizes the discussions and outcomes of the second session of the WCRP Data Advisory Council (WDAC) held the 4-5 March 2013, in Darmstadt, Germany. The meeting made progress on a number of core topics at the heart of WDAC’s mandate, namely Essential Climate Variable (ECV) inventories, data archives, data set quality assessments, data assimilation and reanalysis. Walter Meier briefed the Council on CliC and related polar science activities including: workshops, working groups, polar initiatives, the revived Ice Sheet Mass Balance and Sea Level initiative (ISMASS), observational data assessments and coordination of observations with models including among others obs4MIPs, CORDEX, establishment of a “Sea Ice and Climate Modeling Forum” and a “Permafrost Modeling Forum” and creation of the new targeted activities: (1) Antarctic ice-shelf and ocean coupled modeling, (2) Understanding linkages between cryosphere elements,(3) Coordination of cryosphere observations for model evaluation and initialization, and (4) Arctic freshwater synthesis. CliC will play a role in coordinating these activities to maximize outcomes and will provide input and feedback – in close cooperation with WDAC.

CliC SSG 9 Meeting Report and New Priorities Published

The 9th Session of the CliC Scientific Steering Group was held from 4-7 February at the Alfred Wegener Institute in Potsdam, hosted by the International Arctic Science Committee. The meeting began with a critical look at that state of the CliC project and where new foci may be necessary. Several new CliC Targeted Activities were approved. These activities are meant to be ~2 years in duration and produce tangible results. Longer term efforts such as working groups and forums on various topics were also discussed. For a complete report of the meeting and details on new priorities within the CliC Project, download the report.

CliC Participation in CLIVAR Steering Committee Meeting

CliC Director, Jenny Baeseman, attended the CLIVAR Scientific Steering Committee meeting in Kiel, Germany 6-9 May 2013. This created a great opportunity for developing stronger connections between the two WCRP core projects. CLIVAR has managed the CLIVAR/CliC/SCAR Southern Ocean Panel for many years, and hopefully discussions resulting from this meeting will develop stronger participation from CliC. In addition, CLIVAR is managing the WCRP Grand Challenge on Sea Level Rise, which CliC is to contribute expertise on the cryosphere contribution to sea level rise. To help CLIVAR understand the current status of CliC, our new targeted activities, and some of the recent successes of the project were presented. Dr. Baeseman's presentation covered some of the developments of the office, which is now staffed again after several years of hiatus, and some recent developments such as the new agreements with the Norwegian Polar institute, SCAR and IASC, a new SSG Chair and several new SSG members, new website and online tools, highlights from various international workshops, plans for upcoming meetings, the development of a cryosphere projects catalog and specialists directory and the new targeted activities for CliC. Highlights of particular interest to CLIVAR were discussed: In June, the CliC Sea Ice Modeling and Observing Workshop will concentrate on the observational needs for sea ice models; the new Ice Watch project from Jenny Hutchings and Alice Orlich (UAF); the West Antarctic Glacier-Ocean Modelling led by David Holland; the Arctic Freshwater System Synthesis led by Terry Prowse, Arvid Bring and Johanna Karlsson; and CliC will join as co-sponsor of the SCAR/IASC Ice Sheet Mass Balance and Sea Level group (ISMASS). In addition, CLIVAR was encouraged to participate in the WCRP Cryosphere in a Changing Climate Grand Challenge workshop to be held in Tromsø in October. This workshop will help to plan the activities needed to address the grand challenge's science foci: Predictions and Projections of Polar Climate, Cryosphere Model Biases and Shortcoming, Ice Sheet Models, dynamics and sea level rise, Permafrost and Carbon for Earth System Models.
