The following special issues are scheduled for publication in CP:
Paleoclimate Modelling Intercomparison Project phase 4 (PMIP4) (CP/GMD inter-journal SI)
10 Jan 2017–31 Dec 2018 | Guest editors: M. Kageyama, P. Braconnot, S. Harrison, J. H. Jungclaus, B. L. Otto-Bliesner, and M. F. Loutre | Information
The Paleoclimate Modelling Intercomparison Project (PMIP) has been set up to provide a mechanism for coordinating paleoclimate modelling and model evaluation activities, to understand the mechanisms of climate change and the role of climate feedbacks in these changes. PMIP is now in its fourth phase: PMIP4. Five PMIP4 experiments have been proposed within the framework of the CMIP6 exercise. Other periods and sensitivity experiments are also planned to assess climate sensitivity, changes in hydrology, long-term trends and interannual to millennium variability. This special issue is devoted to the description of the design of the PMIP4 experiments, of data syntheses to which model results can be compared, and to papers analysing single or multi-model results from PMIP4 and CMIP6 experiments. Papers can either be submitted to GMD (model and simulation descriptions, data syntheses in support of the experimental design or of model-data comparisons) or CP (in-depth analyses, multi-model analyses, model-data comparisons).
The 10th International Carbon Dioxide Conference (ICDC10 ) and the 19th WMO/IAEA Meeting on Carbon Dioxide, other Greenhouse Gases and Related Measurement Techniques (GGMT-2017) (ACP/AMT/CP/ESD inter-journal SI)
01 Oct 2017–30 Sep 2018 | Guest editors: H. Fischer, N. Gruber, M. Leuenberger, C. LeQuere, J. Pongratz, C. Prentice, J. Randerson, M. Steinbacher, and C. Zellweger | Information
The International Carbon Dioxide Conference (ICDC) is the single largest conference organized by the global research community every four years to present the latest scientific findings on the science of the carbon cycle and its perturbation by human activities. The ICDC10 in 2017 is the 10th anniversary conference. It covers fundamental science advancement and discovery, the generation of policy relevant information, and observational and modeling approaches. ICDC10 brings together scientists from different disciplines to work towards an integrated view on the global cycle of carbon in the Earth system.
The main themes of the conference are as follows:
GGMT-2017 is a key conference on measurement techniques for accurate observation of long- lived greenhouse and related gases, their isotopic composition in the atmosphere relevant for climate change, and global warming research findings. The biannual meeting, known as the WMO/IAEA Meeting of Experts on Carbon Dioxide, Other Greenhouse Gases and Related Tracer Measurement Techniques, is to be held for the 19th time in 2017.
The special issue is open for papers that emerged from ICDC10 and GGMT -2017 conference contributions.
Climate of the past 2000 years: global and regional syntheses
01 Jul 2016–28 Feb 2017 | Guest editors: H. McGregor, P. Francus, N. Abram, M. Evans, H. Goosse, L. von Gunten, D. Kaufman, H. Linderholm, M.-F. Loutre, R. Neukom, and C. Turney | Information
The 2013 PAGES 2k consortium reconstructions have shown clear regional expressions of temperature variability at the multi-decadal to century scale, whereas a long-term cooling trend prior to the 20th century is evident globally. These findings pointed to the necessity of understanding regional differences for a truly global view. This special issue intends to assemble papers proceeding from the coordinated efforts of the PAGES 2k network to refine temperature reconstructions and create a history of regional precipitation changes. To achieve this goal, it will gather a series of synthesis papers from each PAGES regional group, i.e Australasia, Arctic, Antarctic, South and Central America, North America, Europe, Asia and from the Oceans, as well as transregional comparisons. This special issue will include reconstructions from not only various types of archives, e.g. documents, tree rings, sediments and ice, but also model-proxy comparisons, analyses of modes of variability and assessments of dating uncertainties.
Southern perspectives on climate and the environment from the Last Glacial Maximum through the Holocene: the Southern Hemisphere Assessment of PalaeoEnvironments (SHAPE) project
01 Dec 2015–30 Jun 2017 | Guest editors: S. Phipps, A. Lorrey, M. Rojas, H. Bostock, and N. Abram | Information
The Southern Hemisphere Assessment of PalaeoEnvironments (SHAPE) is an INQUA-supported project focused on environmental and climate variability and change covering the last 60,000 years. This special issue of Climate of the Past is a contribution of SHAPE toward understanding atmosphere and ocean circulation, hydroclimate change, and cryosphere responses from the global Last Glacial Maximum through the Holocene. Many of the studies combine emerging dating and age-modeling techniques, interpretations of physical proxy records of the environment, quantitative climate reconstructions, and climate simulations to investigate this key interval. The collective work will enrich our knowledge about the dynamics, interconnectivity, and timing of changes in the late Quaternary for the Southern Hemisphere.
Climate–carbon–cryosphere interactions in the East Siberian Arctic Ocean: past, present and future (TC/BG/CP/OS Inter-Journal SI)
01 Oct 2015–31 Mar 2017 | Guest editors: M. Jakobsson, C. Barbante, and T. Cronin | Information
This special issue, spanning different Copernicus journals, tallies the current understanding of the cryosphere–carbon–climate (CCC) interactions in the East Siberian Arctic Ocean (ESAO) and related areas.
The ESAO is the largest shelf sea system of the World Ocean. It is perennially ice-covered, receives inflow from large rivers, hosts most of the Arctic subsea permafrost and shallow gas hydrates, and is one of the areas that have been experiencing the largest warming in recent decades. Despite its importance to a wide range of geoscience issues, this system has historically been only sparsely investigated. There has however been a number of major expeditions to the region in recent years, including the 90-day icebreaker-based SWERUS-C3 expedition in summer 2014. The current interest in the past, present and future functioning of this system makes it ripe for a major special issue.
Carbon/methane from this area may be remobilized and interact with large-scale biogeochemical cycles and the climate. The history of the ESAO cryosphere also includes the question of Pleistocene ice sheet extents, and the region has experienced one of the largest summer sea ice reductions in the Arctic Ocean during the last decades, with implications for ocean and atmospheric circulation, air–sea interactions and marine life, as well as erosional release of coastal permafrost carbon and sediment dynamics. Stimulated by recent field campaigns such as SWERUS-C3, submissions will be encouraged from all known programmes, spanning from deep geology, via permafrost carbon release and land–shelf–basin interactions, to palaeoglaciology, as well as a wide range of ocean and atmosphere processes. The aim of the special issues is to provide a well-contained collection of improved understanding of the ESAO-CCC interactions from geological timescales to contemporary processes to projections of future trajectories.
The special issue is open for all submissions within its scope (contingent on the chief editor's decision).
PlioMIP Phase 2: experimental design, implementation and scientific results
01 Aug 2015–31 Dec 2018 | Guest editors: Alan Haywood, Aisling Dolan, and Wing-Le Chan | Information
The Pliocene Model Intercomparison Project (PlioMIP) Phase 2 is a strategic international climate modelling initiative that compares model predictions and uses climate models and geological proxy data together to better understand climate and environments of the late Pliocene. PlioMIP2 is also exploring the relevance of the Pliocene in the context of future climate change. We welcome submissions from registered participants that document the results of climate model simulations for the Pliocene using the PlioMIP2 protocols. These simulations will facilitate analyses of the dynamics of Pliocene climate and compare climate model results with each other. In addition comparisons of climate model results with proxy data will be presented.
