Primary glioblastoma of the cerebellopontine angle in adults
Authors: Wu Bo , Liu Weidong , Zhu Hong , Feng Hailong , Liu Jinping
Published: January 2011

Gliomas are rare entities in the cerebellopontine angle (CPA) in adults. The authors present clinical, neuroradiological, serological, and neuropathological findings in a 60-year-old man with an extraaxial CPA glioblastoma arising from the proximal portion of cranial nerve VIII. The patient presented with progressive left-sided deafness and left-sided facial palsy lasting less than 2 months and progressive dysarthria and dysphagia lasting 2 weeks. Preoperative neuroimaging suggested the diagnosis of CPA meningioma with “dural-tail” sign and involvement of the internal auditory canal. Serological examination showed an increase in the malignant markers of ferritin and neuron-specific enolase, which suggested underlying malignancy. The tumor was subtotally removed, and it was confirmed to be completely separated from the brainstem and cerebellum. Cranial nerves VII and VIII were destroyed and sacrificed. Transient severe bradycardia occurred during surgery due to entrapment of the caudal cranial nerve complex by the tumor in such an infiltrative way. The neuropathological examination revealed a glioblastoma. The patient underwent no further treatment and died of cachexia 2 months postoperatively. To the authors' knowledge, this represents the first case of a primary glioblastoma in the CPA in an adult. A high index of suspicion along with reliance on clinical assessment, radiological findings, and serum detection of specific malignant markers is essential to diagnose such uncommon CPA lesions.
Basal Freezing of Squeezed Water: Its Influence on Glacier Erosion
Authors: Souchez R.A. , Tison J.-L.
Published: January 2011

The basal ice layer of Glacier de Tsidjiore Nouve in the Swiss Alps consists of debris bands and associated clear ice lenses. This layer is due to refreezing of squeezed water at the sale of the glacier, as evidenced by the chemical properties of the ice. Active erosion processes include entrainment of debris in the basal ice layer and abrasion on rock protuberances immediately down-glacier. The formation of the basal ice layer requires that the temperature of the squeezed water, which is determined by the pressure-melting point within the basal ice, should be below the freezing temperature of the pore water in the subglacial debris layer. This would be the case if the pore water were at a pressure lower than the basal ice pressure.
Glacier Erosion and Sedimentation in the Volcanic Regions of Kamchatka
Authors: Vinogradov V.N.
Published: January 2011

The recent topography of Kamchatka was formed by the joint activity of endogenic and exogenic processes among which glacial erosion and sedimentation played the most important role. Glacial erosion is exhibited to different degrees on old and young mountains. Corrie and corrie-valley glaciers are common to the oldest and strongly eroded early Pleistocene volcanoes. The flanks of Holocene volcanoes are only s1ightly affected by exogenic processes. As a result, ice caps and ice belts as well as crater glaciers are developed on them.

During earlier glaciations, the influence of volcanism on glaciers and frozen strata caused the specific conditions for sub-ice eruptions, as a result of which strata of welded tuffs and pumices, and thick strata of fragmented material were formed. Recent and older glaciers in regions of active volcanism are covered by large amounts of pyroclastic material. During intense melting of glacier ice in these regions, thick fields of morainic deposits were formed. Similar conditions are found in Iceland, as describeo by (Thorarinsson 1958, Thorarinsson 1974), among others.
Depositional Landforming Processes at the Snouts of Five Surging Glaciers in Vestspitsbergen (Abstract only)
Authors: Croot D. G.
Published: January 2011

Recent work by Clapperton (1975) proposes that the rapid rates of advance experienced by glaciers which surge may lead to enhanced debris incorporation, increased compressive flow near the glacier snout at the point of maximum extension, and to the upward translation and vertical stacking of debris near the glacier snout and margin. Five glaciers in Spitsbergen (Battyebreen, Holmströmbreen, Lisbetbreen, Vonbreen, Elnabreen) display morphological features which are widely accepted as being diagnostic of surging glaciers.

Results of detailed observations regarding the nature, distribution, melt-out, and reworking of englacial debris at Battyebreen are presented. Basally derived till is brought to the surface of the glacier in narrow lateral and terminal belts, no more than 100 m wide. Within this zone, (i.e. up-valley from the snout and towards the valley centre) the ice is debris-free with the exception of small amounts of en-glacial debris which form the core of lobate medial moraines. Differential ablation of debris-free and debris-rich ice leads to the production of a topographic basin within which melt-out and reworking processes occupy restricted locations, as follows. Immediately inside the encircling melt-out till, a zone of flow tills is found. Melt streams are located at the foot of, the flow till-mantled slope, producing narrow (150 m wide) outwash trains, which merge into deltas. The central area of the topographic basin is occupied by a supraglacial lake.

Observations of the remaining four locations confirm that other glaciers in the vicinity, which display similar characteristics associated with surging, are developing a stagnant-ice zone of identical appearance. The pattern of processes observed at Battyebreen is thus repeated at each site.

A simple model of depositional landscape development is proposed for surging valley glaciers in a sub-polar environment.
Seasonal Variation of Solute Concentration in Melt Waters Draining from an Alpine Glacier
Authors: Collins D.N.
Published: January 2011

Electrical conductivity of melt waters draining from the portal of Gornergletscher, Switzerland, was recorded continuously for extended periods during the 1978‐79 hydrological year. Conductivity was used as a surrogate measure of the total dissolved solids concentration in melt water to describe the seasonal variation of solute, and its relation to discharge, in an attempt to use melt-water hydrochemistry as an indicator of the nature of subglacial processes within an alpine glacier. In winter, conductivity was 2 to 10 times higher than during the summer ablation season. and also showed considerable diurnal and annual variations independent of discharge. The transition from winter to summer discharge regime was preceded by falling solute concentration. A distribution shaped as a “triangle-with-spike” describes the complex relationship between discharge and electrical conductivity for the annual cycle of run-off. Almost all the solute load from beneath Gornergletscher is evacuated during summer. Melt-water hydrochemistry provides some insight into the nature of sub-glacial chemical processes, but, since melt waters do not appear to have access to all areas of the glacier bed, it probably under-estimates total chemical activity.
Distinguishing characteristics of Diamictons at the Margin of the Matanuska Glacier, Alaska
Authors: Lawson Daniel E.
Published: January 2011

The origins of diamictons deposited at the Matanuska Glacier are identified in stratigraphic sequences mainly by the presence or absence of a pebble fabric, internal structure, and variation in gravel-size clast distribution. These properties correlate with major differences in depositional mechanisms and source material. Melt-out till mostly inherits fabric, internal structure, and grain-size distribution from its debris-laden basal ice source. Sediment flow deposits and ice-slope colluvium (deposited by ablational slope processes) have properties developed by resedimentation mechanisms. Melt-out till ranges from structureless to stratified with interspersed lenses and discontinuous laminae, and generally possesses a well-defined pebble fabric. Sediment flow deposits show various combinations of six sedimentologic units with distinct sedimentary features and clast dispersion. Pebble fabric is absent or poorly defined, depending upon the unit's origin. Ice-slope colluvium is usually featureless, except for randomly-dispersed laminated lenses and irregularly-shaped gravelly zones in an otherwise disarrayed assemblage of particles, and is without a pebble fabric.
Observations on Debris in the Basal Transport Zone of Mýrdalsjökull, Iceland
Authors: Humlum Ole
Published: January 2011

Mýrdalsjökull is a temperate ice cap with an area of 596 km2, covering the volcanic Katlamassif in southern Iceland. Since 1900, extensive areas of ground moraine have been exposed during glacier retreat along the northern margin of the ice cap. The ground moraine surface is characteristically covered by a coarse layer of rock particles 10 to 150 mm in size. At the present glacier front, particles of corresponding size can be seen melting out from the lowermost glacier ice. Samples of ice and debris were collected from the basal transport zone. here generally 20 to 50 mm thick. and the volume, grain size, shape, and surface texture were determined. The orientation of rock particles in the englacial position. in the basal transport zone, and in the under lying lodgement till were analysed. The rock particles that dominate the debris content in the basal transport zone and constitute the coarse surface layer beyond the glacier margin are interpreted as a residual, which has escaped subglacial frictional deposition.
Glacial Abrasion and Sliding: their Dependence on the Debris Concentration in Basal Ice
Authors: Hallet Bernard
Published: January 2011

A model of bedrock abrasion by a temperate glacier is developed that takes into account the significant impeding effect of scattered rock fragments at the ice-rock interface on glacier sliding. An increase in the debris concentration above a relatively low value can reduce the abrasion rate by decreasing both the flux of rock fragments and the effective forces which press fragments against the bed. Abrasion of a simple wavy bed is shown to be most rapid for a relatively low debris concentration above which the abrasion varies inversely with the debris content. A similar concentration dependence of abrasion is expected for beds of arbitrary geometry but low roughness. Sliding glaciers will tend to abrade until the basal ice is nearly stagnant at which point rocks of all sizes start to lodge against the bed.
Comparative Study of Immune-Diagnostic Tools with Polymerase Chain Reaction in Sub-Clinical Leishmaniasis Isolates
Authors: Abdalla Nazar M
Published: January 2011

Objective: This study aimed to identify cases of leishmaniasis in the Nuba Mountain area, which is situated in a unique geographical site located in the centre of Sudanese leishmania belt. Wide range of investigations are available for detection of leishmania cases, but still the most reliable and easy test used as screening and epidemiological tool in field studies needs to be evaluated. The most commonly used conventional diagnostic methods direct microscopy and culture have some drawbacks in diagnosing subclinical cases of leishmaniasis. Materials and methods: In this study, comparative properties of various immune-diagnostic tools with Polymerase Chain Reaction used in sub-clinical leishmaniasis isolates were explored. The immune-diagnostic tools involved in this study include- Leishmanin Skin Test (LST), Enzyme Linked Immunosorbent Assay (ELISA) and Direct Agglutination Test (DAT). The study was conducted in the Green Valley village (Rashad Province, South Kordofan State) with a population of 332. Most of the villagers presented with sub-clinical form of leishmaniasis with minor symptoms and signs without the features found in clinical form of visceral leishmaniasis such as fever, diarrhoea, epistaxis, enlarged lymph nodes, spleen and liver. In this study we collected demographic, clinical and epidemiological data using special questionnaire. Leishmanin skin test (LST), ELISA, DAT and PCR for parasite DNA detection were used. Result: The final positive cases detected by PCR were 32 out of 332 belong to L. donovani species. The final positive cases detected by LST were 51.2% of the total population under study, while 11 out of the 37 tested samples were positive by ELISA. All of the 332 villagers showed negative readings by DAT with exception of three individuals who were positive with very high titers. Conclusion: DNA etxtraction and amplification with primers can be a good screening tool in subclinical leishmaniasis isolates.

Published: January 2011

Patients with nephrotic syndrome presents a high risk of arterial and venous thrombosis, mainly deep vein thrombosis and renal vein thrombosis (RVT). We describe two cases of patients with diagnosis of membranous nephropathy and RVT. The first patient was 32 years, male, and admitted with nephrotic syndrome. Laboratory tests showed urea 16mg/dL, creatinine 0.9mg/dL; proteinuria 17g/day. Abdominal ultrasound evidenced obstruction of right and left renal veins and left inferior vena cava. Renal biopsy was compatible with membranous nephropathy. The second patient, a 27 years old male was admitted with nephritic syndrome. Laboratory tests at admission showed urea 25mg/dL; creatinine 1.1mg/dL; 24h proteinuria 3.86g, abdominal ultrasound showed endoluminal obstruction of left renal vein and increased size left kidney. Renal biopsy showed membranous nephropathy. RVT is not common in patients with nephrotic syndrome, and it is more frequent in membranous nephropathy. Treatment includes intravenous anticoagulant followed by oral drugs. Prophylaxis in nephritic patients is controversial.

Conçu suivant les normes propres aux écoles d'Alexandrie sous la forme d'une praxis (leçon ou cours), répartie entre une théôria (exposé théorique) et une lexis (explication du texte), le commentaire de Stéphanos réunit des éléments rigoureusement dissociés par Galien : une pragmateia (traité technique), destinée aux médecins praticiens, et l'hypomnèma (commentaire-explication du texte), composé à l'intention du public cultivé épris de l'Antiquité. Poussant plus loin encore ses préoccupations didactiques, Stéphanos transforme d'une part (surtout dans son commentaire du Prognostikon) ses théôriai en de véritables petits traités techniques, pour ménager une transition entre la science contemporaine et, les doctrines d'Hippocrate ; il propose d'autre part toute une série de règles exégétiques (en grande partie empruntées à Galien), qui permettent à ses jeunes étudiants d'accéder aux textes anciens, souvent ambigus.

Global competition and environmental factors make it increasingly necessary in many countries to establish a strategic plan for various national food and bioenergy chains. Neves (2007) developed a simple method (CHAINPLAN) to help in the process of developing a strategic plan for a food chain, which has been applied to chains in various countries. The objective of this paper is to report the results of a new application of (part of) this method: to the sugarcane chain in Brazil. As this chain has an important trade association (UNICA – Brazilian Sugarcane Industry Association) for coordination of collective actions, the paper focuses on two specific steps: the mapping and quantification of the chain; and the elaboration of the strategic plan. The chain mapping and quantification procedure, which is the second step of the method, quantifies an industry's contribution to the country's GDP, as well as to job creation, tax generation, and the distribution of economic activities. In relation to the sugarcane chain in Brazil, it was found that the sugar-energy sector GDP in 2008 was US$ 28.15 billion, equivalent to 2% of the total Brazilian GDP. The estimated total value of sales of the various links that comprise the sugarcane chain reached US$ 86.8 billion. Completion of step 2 of the CHAINPLAN method allows the chain's agents to conduct a macro-environmental and internal analysis of the chain to identify strategic projects (collective actions) to improve the chain's competitiveness. This step was also carried out on the Brazilian sugarcane chain.
Coopetition: insights from the agri-food supply chain
Authors: Walley Keith , Custance Paul
Published: January 2011

Organisations that simultaneously cooperate and compete are engaged in what has become known as 'coopetition'. The agri-food sector is one of the oldest and most established supply chains. It contains numerous examples of coopetition and this paper uses six cases drawn from the sector to investigate the concept and operation of coopetition. Observation of the cases leads to a number of lessons that may be of value to management practitioners interested in adopting coopetative strategies as well as to individuals responsible for developing policy within the agri-food supply chain, and academic researchers undertaking further inquiry into the concept of coopetition.

This paper provides a comparison of the vascular exotic flora of Sardinia and that of the Balearic Islands, both territories belonging to the Western Mediterranean biogeographic subregion. The study has recorded 531 exotic taxa in Sardinia (18.8% of the total flora) while 360 (19%) in the Balearic Islands; 10 are new to Sardinia (3 of which for Italy) and 29 to the Balearic Islands. The alien flora of Sardinia is included in 99 families; Fabaceae is the richest (49 taxa), followed by Poaceae (33) and Asteraceae (31) while in the Balearic Islands in 90 families, with a predominance of Fabaceae (32), Asteraceae (31) and Poaceae (27). The comparison of the biological spectra reveals that in Sardinia phanerophytes are the most represented in Sardinia and therophytes in the Balearic Islands. A detailed analysis shows that most of the exotic taxa (246) are shared by both territories with a clear dominance of neophytes rather than archaeophytes. A study of the geographical origin shows supremacy of the American element over the Mediterranean. The majority of introduced exotic taxa are a result of intentional human introductions (76% SA, 77% BL), mainly for ornamental use (43% SA, 45% BL). The most occupied habitats are the semi-natural, agricultural and synanthropic for both territories, but attending to invasive plants, coastal habitats in Sardinia and wetlands in the Balearic Islands are the most sensitive. A part of the work deals with the causes of fragility and low resilience of the different habitats.
Botanical novelties from Sierra de Maigualida, southern Venezuela. I
Authors: Nozawa Shingo , Grande José R. , Huber Otto
Published: January 2011

The almost unexplored Sierra de Maigualida is the largest and highest non sedimentary, granitic mountain system in the Guayana Shield. Because of its particular geological constitution, a surprisingly large number of new plant taxa has been found in its high mountain ecosystems. In this first installment, two new species, Sauvagesia cryptothallis (Ochnaceae) and Aegiphila uasadiana (Lamiaceae) are described and illustrated. Sauvagesia cryptothallis belongs to Sauvagesia sect. Imthurnianae and is closely related to S. imthurniana, differing mainly in the axis of the inflorescence being densely covered by 5-8 tightly overlapping bracts, hiding the entire axis, and with the principal and secondary leaf veins almost flat, not salient on the lower surface, and poorly differentiated from tertiary veins. Aegiphila uasadiana is a very distinctive species somewhat similar to A. luschnathii, from Brazil. It can be distinguished by its leaves that are coriaceous, conspicuously revolute, entire, shiny, gla brescent, conspicuously bullate, and foveate adaxially; the inflorescences that are relatively compact and crowned at the apex of the twigs; the calices that are adpressed-pubescent, densely so at the base, progressively glabrescent towards the apex, truncate apex, 4-apiculate, each apiculi of ca. 0.4 mm long, and stamens that are largely exserted from the corolla.
Anatomy and fruit development in Schinopsis balansae (Anacardiaceae)
Authors: González Ana María , Vesprini José Luis
Published: January 2011

Schinopsis balansae Engl. is a dioecious tree; reproduction is by woody samaras containing a single seed. Fruit set is high, even in isolated trees, empty fruits are frequent and account for a high proportion of the total fruit production. To describe the anatomy and the ontogeny of seeded and seedless fruits, flowers and fruits at different development stages from bagged and pollen exposed flowers were studied. The development and the anatomy of the pericarp in seeded and parthenocarpic fruits did not differ. It consisted in an exocarp formed sensu lato from the external epidermis of the ovary and some layers of the underlying parenchyma. The mature mesocarp was constituted by a sclerified tissue and lysigenous channels. The fruit is of Anacardium type: the endocarp presented three sclerenchymatic and a crystalliferous layer. The endocarp development was also sensu lato because it was formed from the epidermis and the hypodermis of the carpel. This organization agrees with the only species described in the genus: S. haenkeana Engl. Schinopsis balansae is able to produce parthenocarpic fruits in the absence of pollination. Empty fruits from free exposed flowers presented embryos arrested at different stages, although total absence of an embryo was the most common condition. Parthenocarpy seems to be a plesiomorphic trait within the Anacardiaceae, but regardless of its origin, the maintenance of empty fruit production in a wind-dispersed samara is difficult to explain. Whether parthenocarpy has an adaptive value, or is an evolutionary constraint remains unclear in Schinopsis.

The 4-H Youth Development program prohibits all forms of discrimination which includes disability. 4- H Extension professionals provide the essential interface between Extension and the local community to create an inclusive environment for all youth, including those with disabilities, that is welcoming and accessible. Attitudes and self-efficacy for working with youth who have disabilities impacts how well 4- H delivers positive youth development programs. The purpose of this study was to determine state-wide 4-H Extension professionals’ attitudes, self-efficacy, and perceptions of inclusion toward youth with disabilities. In addition, the researchers sought to examine their use of a training program to better serve youth with disabilities. All 4-H Extension professionals in Ohio were surveyed (N = 135) with 71 responding (response rate of 53%). Results indicated the attitudes of Extension professionals for accepting of and feeling comfortable around youth with disabilities was overwhelmingly positive. They also perceived that youth with disabilities felt that they were included in 4-H activities. For self-efficacy, 4-H professionals reported they could effectively provide inclusive opportunities for youth with disabilities and adapt their level of instruction, take extra time, and pay attention to the needs of youth with disabilities. However, about a third of the respondents somewhat or strongly agreed that their workload would increase by having youth with disabilities in their organization. The disability training program was used by over three-fourths of the 4-H professionals and helped them to engage with parents to learn more about their children with disabilities. The program also improved accommodations and creating a more inclusive 4-H environment.

In this case study, we explored an innovative Professional Development (PD) approach where teachers were positioned as experts and drivers of change. Simplified as Participatory PD, Michigan State University Agriculture, Food, and Natural Resources (AFNR) Education faculty constructed an experience for Michigan AFNR Educators following the characteristics of effective PD. We then employed a case study design to explore AFNR Educators’ perceptions of the Participatory PD experience. Seventeen AFNR Educators engaged in the participatory PD. During the PD, educators were tasked with creating a state-wide AFNR Education curriculum resource. Data collection included focus group interviews with teacher-participants, a facilitator interview, researcher observations, and researcher reflections. Data were transcribed verbatim and analyzed using a multi-stage process based on the constant comparative method of analysis. Four themes emerged from the data: (a) Professional Development, (b) Learning, (c) Perspective, and (d) SBAE Change. Conclusions from the case study include a discussion of the outcomes reached by teacher-participants who engaged in the participatory PD, the essential role of collective teacher expertise in achieving those outcomes, and teacher preference for the participator PD approach. Recommendations include the need for additional research on participatory PD alongside recommendations for leaders in AFNR Education to implement participatory PD.

An important fingerprint of wildfires on the European aerosol load
Authors: Barnaba F. , Angelini F. , Curci G. , Gobbi G. P.
Published: January 2011

Abstract. Wildland fires represent the major source of accumulation mode aerosol (i.e., atmospheric particles with diameters <1 μm). The largest part of these fires occurs in Africa, Asia and South America, but a not negligible fraction also occurs in Eastern Europe and former USSR countries, particularly in the Russian Federation, Ukraine and Kazakhstan. Apart for exceptional cases as the Russian fires of summer 2010, routine agricultural fires in Eastern Europe and Russia have been recently shown to play a crucial role in the composition of the Arctic atmosphere. However, an evaluation of the impact of these fires over Europe is currently not available. The assessment of the relative contribution of fires to the European aerosol burden is hampered by the complex mixing of natural and anthropogenic particle types over the continent. In this study we use long term (2002–2007) satellite-based fires and aerosol data coupled to atmospheric transport modelling to attempt unravelling the wildfires contribution to the European aerosol optical thickness (AOT). Based on this dataset, we provide evidence that fires-related aerosol emissions play a major role in shaping the AOT yearly cycle at the continental scale. In general, the regions most impacted by wildfires emissions and/or transport are Eastern and Central Europe as well as Scandinavia. Conversely, a minor impact is found in Western Europe and Western Mediterranean. We estimate that in spring 5 to 35% of the European fine fraction AOT (FFAOT, i.e., the AOT due to accumulation mode particles) is attributable to wildland fires. The calculated impact maximizes in April (20–35%) in Eastern and Central Europe as well as in Scandinavia and in the Central Mediterranean. An important contribution of wildfires to FFAOT is also found in summer over most of the continent, particularly in August over Eastern Europe (28%) and the Mediterranean regions, from Turkey (34%) to the Western Mediterranean (25%). This unveiled, fires-related, continent-wide haze is expected to play a not negligible role on the European radiation budget, and possibly, on the European air quality, therefore representing a clear target for mitigation.
Thermospheric vorticity at high geomagnetic latitudes from CHAMP data and its IMF dependence
Authors: Förster M. , Haaland S. E. , Doornbos E.
Published: January 2011

Abstract. Neutral thermospheric wind pattern at high latitudes obtained from cross-track acceleration measurements of the CHAMP satellite above both polar regions are used to deduce statistical neutral wind vorticity distributions and were analyzed in their dependence on the Interplanetary Magnetic Field (IMF). The average pattern confirms the large duskside anticyclonic vortex seen in the average wind pattern and reveals a cyclonic vorticity on the dawnside, which is almost equal in magnitude to the duskside minimum. The outer shape of the vorticity pattern agrees approximately with the outer boundary of region-1 currents in the well-known average current distributions of Iijima and Potemra (1976) The IMF dependence of the vorticity pattern resembles the characteristic FAC and ionospheric plasma drift pattern known from various statistical studies obtained under the same sorting conditions.
Adaptive method of lines for multi-component aerosol condensational growth and CCN activation
Authors: Arabas S. , Pawlowska H.
Published: January 2011

Abstract. The process of formation of cloud droplets on an ensemble of aerosol particles is modelled by numerous investigators using the method of lines (MOL). The method involves discretisation of the aerosol size spectrum into bins whose positions evolve with time. One of the drawbacks of the method is its poor representation of the aerosol spectrum shape in the region between the unactivated aerosol mode and the activated droplet mode. An adaptive grid refinement procedure is introduced. The procedure splits any overly wide bins into several narrower ones during integration. The number of new bins added is a function of particle concentration in the bin being split. Application of the grid refinement procedure results in suppression of the sensitivity of the computed cloud droplet spectrum characteristics such as droplet number concentration or effective radius to the initial grid choice. A model of droplet formation on multi-component aerosol is formulated for the purpose of the study. Model formulation includes explicit treatment of the droplet temperature evolution. Several examples of the model set-up are used to demonstrate model capabilities. Model results are compared to those without adaptivity. A C++ implementation of the model is available as an electronic supplement of the paper.

Abstract. Simulations of climate over the Last Millennium (850–1850 CE) have been incorporated into the third phase of the Paleoclimate Modelling Intercomparison Project (PMIP3). The drivers of climate over this period are chiefly orbital, solar, volcanic, changes in land use/land cover and some variation in greenhouse gas levels. While some of these effects can be easily defined, the reconstructions of solar, volcanic and land use-related forcing are more uncertain. We describe here the approach taken in defining the scenarios used in PMIP3, document the forcing reconstructions and discuss likely implications.
