Pterostichus Melanarius

At present, climate change significantly affects living organisms on the planet, leading to transformations in their niches, ranges and abundance. The aim of our work was to forecast the range of the representative of the large family Carabidae, famous for its indicative characters, richness and importance in soil communities. We used 19 bioclimatic variables of Bioclim according to our own data and the data of GBIF with the help of the MaxEnt program. We used 550 coordinates of ground beetle Pterostichus melanarius (Illiger, 1798) records. We distinguished the potential range the species studied and drew prognostic maps of the species’ distribution related to climate change according to four scenarios. Mean annual temperatures and the mean temperature in the warmest and the coldest quarters of the year were the major factors affecting spatial distribution of P. melanarius. Visualization of potential range according to RCP 2.6, RCP 4.5 and RCP 6.0 scenarios predicted range reduction by 2050 but its recovery by 2070. According to RCP 8.5 scenario, the range of the species studied will be significantly transformed: by 2070 the range will shift towards the north-west in the continental European states but to the northeast – in the coastal states. By 2070 almost all southern territories of Europe will become unsuitable for P. melanarius survival. The most visible changes will be the shift in range to the north in the eastern part of the European plain. The comfort conditions for P. melanarius decrease in mountain regions including the Alps, Carpathians, Caucasus and Urals. By 2070, the cenotic optimum significantly decreases on the Balkan Peninsula. Thus, a sharp reduction in Southern European and Mediterranean populations is predicted.

14C Age

In many parts of the world, freshwater crisis is largely due to increasing water consumption and pollution by rapidly growing population and aspirations for economic development, but, ascribed usually to the climate. However, limited understanding and knowledge gaps in the factors controlling climate and uncertainties in the climate models are unable to assess the probable impacts on water availability in tropical regions. In this context, review of ensemble models on δ18O and δD in rainfall and groundwater, 3H- and 14C- ages of groundwater and 14C- age of lakes sediments helped to reconstruct palaeoclimate and long-term recharge in the North-west India; and predict future groundwater challenge. The annual mean temperature trend indicates both warming/cooling in different parts of India in the past and during 1901–2010. Neither the GCMs (Global Climate Models) nor the observational record indicates any significant change/increase in temperature and rainfall over the last century, and climate change during the last 1200 yrs BP. In much of the North-West region, deep groundwater renewal occurred from past humid climate, and shallow groundwater renewal from limited modern recharge over the past decades. To make water management to be more responsive to climate change, the gaps in the science of climate change need to be bridged.

Zero Sum

This paper examines China’s policy and position in relation to the evolving climate change negotiations in order to explain how China is dealing with the dilemma of meeting its growing development needs while reducing ghg emissions. It argues that global climate governance requires steering and leadership to deal with the interlocked political process; that the developing countries (dcs) right to develop is challenged by the need for ecosystemic standards especially as climate change is seen as a zero-sum game as the more one country emits the less another one can. This is especially problematic as Industrialized countries (ics) appear to be both unwilling and unable to increase growth without increasing emissions. This explains China’s policy of insisting on its right to develop, of demanding that ics reduce their emissions and that they fulfil their obligations under the fccc, while expressing its willingness to take on a voluntary target. The paper argues that China’s state-led transition has eight unique characteristics that may allow it to lead as it moves beyond a no-regrets policy to a circular and green economy, cooperating with other dcs and mobilizing conscious green values in citizens. The question remains—will the initial success and scale of state-led transition lead the global green transition to a sustainable world?

Evaluation Approach

AbstractSoil erosion and contamination are two main desertification indices or land degradation agents in agricultural areas. Global climate change consequence is a priority to predict global environmental change impacts on these degradation risks. This agro-ecological approach can be especially useful when formulating soil specific agricultural practices based on the spatial variability of soils and related resources to reverse environmental degradation. Raizal and Pantanal models within the new MicroLEIS framework, the Ero&Con package, are database/expert system evaluation approach for assessing limitations to land use, or vulnerability of the land to specified agricultural degradation risks. This study was performed in Souma area with approximately 4100 ha extension in the North-West of Iran (west Azarbaijan). Based on 35 sampling soils, Typic Xerofluvents, Typic Calcixerepts, Fluventic Haploxerepts and Fluventic Endaquepts were classified as main subgroups. Climatological data, referred to temperature and precipitation of more than 36 consecutive years were collected from Urmieh station reports and stored in monthly Climate Database CDBm, as a major component of MicroLEIS DSS (CDBm) program. Climate data for a hypothetical future scenario were collected from the Intergovernmental Panel on Climate Change (IPCC) reports for the 2080s period. The evaluation approach predicts that attainable water erosion vulnerability classes were none (V1) very low (V2) and moderately low (V4) in the total of 72%, 13% and 15% of the Souma area, respectively and they will not affected by climate change. On contrary, attainable wind erosion vulnerability classes will increase. Also, phosphorous and heavy metal contamination vulnerability risks will not differ in two compared scenarios while nitrogen and pesticides vulnerability classes will be improved.

Farming can be shown to have spread very rapidly across the British Isles and southern Scandinavia around 6000 years ago, following a long period of stasis when the agricultural ‘frontier’ lay further south on the North European Plain between northern France and northern Poland. The reasons for the delay in the adoption of agriculture on the north-west fringe of Europe have been debated by archaeologists for decades. Here, we present fresh evidence that this renewed phase of agricultural expansion was triggered by a significant change in climate. This finding may also have implications for understanding the timing of the expansion of farming into some upland areas of southern and mid-latitude Europe.

Over the past decade the governance of global climate change has evolved into a complex, multi-level process involving actors and initiatives at multiple levels of social organization from the global to the local in both the public and private spheres. This article analyzes the North American Commission for Environmental Cooperation (CEC) as one component of this multilevel governance system. Specifically, it evaluates the CEC as a site of regional climate governance based on three potential advantages of governance through regional organizations: a small number of actors, opportunities for issue linkage, and linkage between national and global governance systems. On each count I find that the benefits of a CEC-based climate governance system are limited and argue for greater consideration of how such a system would interact with other forms of climate governance in North America.

The Mississippian Derbyshire and North Wales carbonate platforms were formed in similar tectonic settings within the Pennine and East Irish Sea Basin, respectively. The Derbyshire Platform was surrounded by sub-basins to the north, west, and south whilst the North Wales Platform, 130 km west, had a simpler land-attached geometry. Comparison of these age-equivalent platforms allows the controls on sedimentation, at an important juncture in Earth history, to be evaluated. Both platforms are dominated by moderate-to-high-energy, laterally discontinuous facies, with weak evidence for facies cyclicity, suggesting multiple controls on deposition. Influx of siliciclastic mud on the North Wales Platform led to perturbations in carbonate accumulation; along with abundant palaeosols and coal beds this implies a more humid climate, or shallower water depths compared to the Derbyshire Platform. On both platforms, exposure surfaces can rarely be correlated over >500 metres except for a regionally correlative palaeokarstic surface at the Asbian-Brigantian boundary. This exposure event appears to coincide with a significant regional facies change. Given the lack of evidence for ordering and cyclicity within the strata, the Asbian-Brigantian boundary may mark a significant event that could reflect onset of a transitional climate, prior to the second glaciation event in the Late Palaeozoic Ice Age.
