In this study, a regional climate model was used to dynamically downscale 15 future climate projections from three GCMs covering four emission scenarios (SRES B1, A1FI, A1B, A2) based on Coupled Model Intercomparison Project phase 3 (CMIP3) datasets to 6-km horizontal resolution over the whole Peninsular Malaysia. Impacts of climate change in the 21st century on the precipitation, air temperature, and soil water storage were assessed covering ten watersheds and twelve coastal regions. Then, by coupling a physical hydrology model with the regional climate model, the impacts of the climate change on river flows were assessed at the outlets of ten watersheds in Peninsular Malaysia. It was found that the increase in the 30-year mean annual precipitation from 1970–2000 to 2070–2100 will vary from 17.1 to 36.3 percent among the ten watersheds, and from 22.9 to 45.4 percent among twelve coastal regions. The ensemble average of the basin-average annual mean air temperature will increase about 2.52 °C to 2.95 °C from 2010 to 2100. In comparison to the historical period, the change in the 30-year mean basin-average annual mean soil water storage over the ten watersheds will vary from 0.7 to 10.9 percent at the end of 21st century, and that over the twelve coastal regions will vary from −1.7 to 15.8 percent. Ensemble averages of the annual mean flows of the 15 projections show increasing trends for the 10 watersheds, especially in the second half of the 21st century. In comparison to the historical period, the change in the 30-year average annual mean flows will vary from −2.1 to 14.3 percent in the early 21st century, 4.4 to 23.8 percent in the middle 21st century, and 19.1 to 45.8 percent in the end of 21st century.

This paper examined the temperature changes from the COordinated Regional climate Downscaling Experiment (CORDEX) over the Middle East and North Africa (MENA) domain called CORDEX-MENA. The focus is on the Arabian Peninsula in the 21st century, using data from three Coupled Model Intercomparison Project Phase 5 (CMIP5) models downscaled by RegCM4, a regional climate model. The analysis includes surface observations along with RegCM4 simulations and changes in threshold based on extreme temperature at the end of the 21st century relative to the base period (1971–2000). Irrespective of the driving CMIP5 models, the RegCM4 simulations show enhanced future temperature changes for RCP8.5 as compared to RCP4.5. The Arabian Peninsula will warm at a faster rate (0.83°C per decade) as compared to the entire domain (0.79°C per decade) for RCP8.5 during the period 2071–2100. Moreover, the number of hot days (Tmax ≥ 50°C) (cold nights: Tmin ≤ 5°C) will increase (decrease) faster in the Arabian Peninsula as compared to the entire domain. This increase (decrease) of hot days (cold nights) will be more prominent in the far future (2071–2100) as compared to the near future (2021–2050) period. Moreover, the future changes in temperature over the main cities in Saudi Arabia are also projected. The RegCM4-based temperature simulation data from two suitable CMIP5 models are recommended as a useful database for further climate-change-related studies.

Abstract. We modeled the carbon (C) cycle in Mexico with a process-based approach. We used different available products (satellite data, field measurements, models and flux towers) to estimate C stocks and fluxes in the country at three different time frames: present (defined as the period 2000–2005), the past century (1901–2000) and the remainder of this century (2010–2100). Our estimate of the gross primary productivity (GPP) for the country was 2137 ± 1023 TgC yr−1 and a total C stock of 34 506 ± 7483 TgC, with 20 347 ± 4622 TgC in vegetation and 14 159 ± 3861 in the soil.Contrary to other current estimates for recent decades, our results showed that Mexico was a C sink over the period 1990–2009 (+31 TgC yr−1) and that C accumulation over the last century amounted to 1210 ± 1040 TgC. We attributed this sink to the CO2 fertilization effect on GPP, which led to an increase of 3408 ± 1060 TgC, while both climate and land use reduced the country C stocks by −458 ± 1001 and −1740 ± 878 TgC, respectively. Under different future scenarios, the C sink will likely continue over the 21st century, with decreasing C uptake as the climate forcing becomes more extreme. Our work provides valuable insights on relevant driving processes of the C cycle such as the role of drought in drylands (e.g., grasslands and shrublands) and the impact of climate change on the mean residence time of soil C in tropical ecosystems.

Abstract. We used the General Ensemble biogeochemical Modeling System (GEMS) to simulate responses of natural and managed ecosystems to changes in land use, management, and climate for a forest/savanna transitional zone in central Ghana. Model results show that deforestation for crop production during the last century resulted in a substantial reduction in ecosystem carbon (C) stock from 135.4 Mg C ha−1 in 1900 to 77.0 Mg C ha−1 in 2000, and in soil organic C stock within the top 20 cm of soil from 26.6 Mg C ha−1 to 21.2 Mg C ha−1. If no land use change takes place from 2000 through 2100, low and high climate change scenarios (increase in temperature and decrease in precipitation over time) will result in losses of soil organic C stock by 19% and 25%, respectively. A low nitrogen (N) fertilization rate is the principal constraint on current crop production. An increase in N fertilization under the low climate change scenario would increase crop yield by 14% with 30 kg N ha−1 and by 38% with 60 kg N ha−1, leading to an increase in the average soil C stock by 12% and 29%, respectively, in all cropland by 2100. The results suggest that the climate changes in the future from current climate conditions will not necessarily become a determinant control on ecosystem C fluxes and crop production, while a reasonable N fertilization rate is critical to achieve food security and agricultural sustainability in the study area through the 21st century, and current cropping systems could be optimized to make full use of the rainfall resource.

Abstract. We used the General Ensemble biogeochemical Modeling System (GEMS) to simulate responses of natural and managed ecosystems to changes in land use and land cover, management, and climate for a forest/savanna transitional zone in central Ghana. Model results show that deforestation for crop production during the 20th century resulted in a substantial reduction in ecosystem carbon (C) stock from 135.4 Mg C ha−1 in 1900 to 77.0 Mg C ha−1 in 2000, and in soil organic C stock within the top 20 cm of soil from 26.6 Mg C ha−1 to 21.2 Mg C ha−1. If no land use change takes place from 2000 through 2100, low and high climate change scenarios (increase in temperature and decrease in precipitation over time) will result in losses of soil organic C stock by 16% and 20%, respectively. A low nitrogen (N) fertilization rate is the principal constraint on current crop production. An increase in N fertilization under the low climate change scenario would lead to an increase in the average crop yield by 21% with 30 kg N ha−1 and by 42% with 60 kg N ha−1 (varying with crop species), accordingly, the average soil C stock would decrease by 2% and increase by 17%, in all cropping systems by 2100. The results suggest that a reasonable N fertilization rate is critical to achieve food security and agricultural sustainability in the study area through the 21st century. Adaptation strategies for climate change in this study area require national plans to support policies and practices that provide adequate N fertilizers to sustain soil C and crop yields and to consider high temperature tolerant crop species if these temperature projections are exceeded.

Abstract. In order to provide probabilistic projections of the future evolution of the Atlantic Meridional Overturning Circulation (AMOC), we calibrated a simple Stommel-type box model to emulate the output of fully coupled three-dimensional atmosphere-ocean general circulation models (AOGCMs) of the Coupled Model Intercomparison Project (CMIP). Based on this calibration to idealised global warming scenarios with and without interactive atmosphere-ocean fluxes and freshwater perturbation simulations, we project the future evolution of the AMOC within the covered calibration range for the lower two Representative Concentration Pathways (RCPs) until 2100 obtained from MAGICC6. For RCP3-PD with a global mean temperature median below 1.0 °C warming relative to the year 2000, we project an ensemble median weakening of up to 11% compared to 22% under RCP4.5 with a warming median up to 1.9 °C over the 21st century. Additional Greenland melt water of 10 and 20 cm of global sea-level rise equivalent further weakens the AMOC by about 4.5 and 10%, respectively. By combining our outcome with a multi-model sea-level rise study we project a dynamic sea-level rise along the New York City coastline of 4 cm for the RCP3-PD and of 8 cm for the RCP4.5 scenario over the 21st century. We estimate the total steric and dynamic sea-level rise for New York City to be about 24 cm till 2100 for the RCP3-PD scenario, which can hold as a lower bound for sea-level rise projections in this region.

Abstract. The CHASE-PL (Climate change impact assessment for selected sectors in Poland) Climate Projections – Gridded Daily Precipitation and Temperature dataset 5 km (CPLCP-GDPT5) consists of projected daily minimum and maximum air temperatures and precipitation totals of nine EURO-CORDEX regional climate model outputs bias corrected and downscaled to a 5 km × 5 km grid. Simulations of one historical period (1971–2000) and two future horizons (2021–2050 and 2071–2100) assuming two representative concentration pathways (RCP4.5 and RCP8.5) were produced. We used the quantile mapping method and corrected any systematic seasonal bias in these simulations before assessing the changes in annual and seasonal means of precipitation and temperature over Poland. Projected changes estimated from the multi-model ensemble mean showed that annual means of temperature are expected to increase steadily by 1 °C until 2021–2050 and by 2 °C until 2071–2100 assuming the RCP4.5 emission scenario. Assuming the RCP8.5 emission scenario, this can reach up to almost 4 °C by 2071–2100. Similarly to temperature, projected changes in regional annual means of precipitation are expected to increase by 6 to 10 % and by 8 to 16 % for the two future horizons and RCPs, respectively. Similarly, individual model simulations also exhibited warmer and wetter conditions on an annual scale, showing an intensification of the magnitude of the change at the end of the 21st century. The same applied for projected changes in seasonal means of temperature showing a higher winter warming rate by up to 0.5 °C compared to the other seasons. However, projected changes in seasonal means of precipitation by the individual models largely differ and are sometimes inconsistent, exhibiting spatial variations which depend on the selected season, location, future horizon, and RCP. The overall range of the 90 % confidence interval predicted by the ensemble of multi-model simulations was found to likely vary between −7 % (projected for summer assuming the RCP4.5 emission scenario) and +40 % (projected for winter assuming the RCP8.5 emission scenario) by the end of the 21st century. Finally, this high-resolution bias-corrected product can serve as a basis for climate change impact and adaptation studies for many sectors over Poland. The CPLCP-GDPT5 dataset is publicly available at http://dx.doi.org/10.4121/uuid:e940ec1a-71a0-449e-bbe3-29217f2ba31d.

The aim of this study was to assess soil erosion changes in the mountainous catchment of the Portaikos torrent (Central Greece) under climate change. To this end, precipitation and temperature data were derived from a high-resolution (25 × 25 km) RegCM3 regional climate model for the baseline period 1974–2000 and future period 2074–2100. Additionally, three GIS layers were generated regarding land cover, geology, and slopes in the study area, whereas erosion state was recognized after field observations. Subsequently, the erosion potential model (EPM) was applied to quantify the effects of precipitation and temperature changes on soil erosion. The results showed a decrease (−21.2%) in annual precipitation (mm) and increase (+3.6 °C) in mean annual temperature until the end of the 21st century, and the above changes are likely to lead to a small decrease (−4.9%) in soil erosion potential.

Abstract The education system of the province of Ontario, Canada ranks among the best in the world and has been touted as a model of excellence for other countries seeking to improve their education system. In a system-wide reform, leaders used a political and professional perspective to improve student performance on basic academic skills. The school system rose to renown after this reform which moved Ontario from a “good” system in 2000 to a “great” one between 2003 and 2010 (Mourshed M, Chijioke C, Barber M. How the world’s most improved school systems keep getting better, a report McKinsey & Company. Retrieved from https://www.mckinsey.com/industries/social-sector/our-insights/how-the-worlds-most-improved-school-systems-keep-getting-better, (2010)). Premier Dalton McGuinty arrived in office in 2003 with education as his priority and was dubbed the “Education Premier” because of this mandate. His plan for reform had two primary goals: to improve student literacy and numeracy, and to increase secondary school graduation rates. McGuinty also wanted to rebuild public trust that had been damaged under the previous administration. The essential element of Ontario’s approach to education reform was allowing educators to develop their own plans for improvement. Giving responsibility and freedom to educators was critical in improving professional norms and accountability among teachers (Mourshed M, Chijioke C, Barber M. How the world’s most improved school systems keep getting better, a report McKinsey & Company. Retrieved from https://www.mckinsey.com/industries/social-sector/our-insights/how-the-worlds-most-improved-school-systems-keep-getting-better, (2010)) and the sustained political leadership throughout the entire reform concluding in 2013 provided an extended trajectory for implementing and adjusting learning initiatives. The Ministry of Education’s Student Achievement Division, which was responsible for designing and implementing strategies for student success, took a flexible “learning as we go” attitude in which the reform strategy adapted and improved over time (Directions Evidence and Policy Research Group. The Ontario student achievement division student success strategy evidence of improvement study. Retrieved from http://www.edu.gov.on.ca/eng/research/EvidenceOfImprovementStudy.pdf, (2014)). This chapter will discuss influences on the reform design and key components of strategies to support student and teacher development and build a relationship of accountability and trust among teachers, the government and the public. The successes and shortcomings of this reform will be discussed in the context of their role in creating a foundation for the province’s next steps towards fostering twenty-first century competencies in classrooms.

<em>Abstract</em>.—How paddlefish <em>Polyodon spathula </em>early-life history dynamics affect recruitment is relatively unknown. We quantified factors affecting age-0 paddlefish abundance, hatch time, growth, and survival in an unimpounded reach of the Mississippi River during 2000–2008. We trawled several habitats, collecting 2,074 age-0 paddlefish from 10 to 170 mm total length. Paddlefish hatch timing varied across years (30–60 d), generally commencing in the middle of April and ending in June when a threshold water temperature was reached and river stage variability increased. Correspondingly, an analysis of covariance revealed a strong interaction between year and habitat for catch per unit effort in the small (10–50 mm) (<em>P </em>= 0.025) and medium (51–100 mm) (<em>P </em>= 0.040) size-classes, indicating that habitat preferences were likely influenced by year. However, no relations between these variables in the large size-class (>100 mm) existed (<em>P </em>= 0.88). Age-0 paddlefish growth rates differed among years (i.e., 1.87–3.31 mm/d) and were positively related to water temperature (<em>r </em>= 0.64; <em>P </em>= 0.083). Mortality rates varied by year (range = –0.26 to –0.57) and were positively correlated with the number of days water temperature was below 28°C during April 15 through July 15 (<em>r </em>= 0.67, <em>P </em>= 0.070). Water temperature and river stage variability may regulate early-life dynamics of paddlefish. Early-life history dynamics are likely interrelated with habitat conditions present in the river. The highest catch rates of young paddlefish were on the main channel side and side channel of islands, suggesting that these habitats are important to paddlefish. Within these habitats, paddlefish frequently occupied moderate velocities (i.e., 0.4–0.6 m/s), moderate depths (i.e., 3–5 m), and sand substrate.

The cryosphere refers to the Earth’s frozen realm. As such, it includes the 10 percent of the terrestrial surface covered by ice sheets and glaciers, an additional 14 percent characterized by permafrost and/or periglacial processes, and those regions affected by ephemeral and permanent snow cover and sea ice. Although glaciers and permafrost are confined to high latitudes or altitudes, areas seasonally affected by snow cover and sea ice occupy a large portion of Earth’s surface area and have strong spatiotemporal characteristics. Considerable scientific attention has focused on the cryosphere in the past decade. Results from 2 ×CO2 General Circulation Models (GCMs) consistently predict enhanced warming at high latitudes, especially over land (Fitzharris 1996). Since a large volume of ground and surface ice is currently within several degrees of its melting temperature, the cryospheric system is particularly vulnerable to the effects of regional warming. The Third Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) states that there is strong evidence of Arctic air temperature warming over land by as much as 5 °C during the past century (Anisimov et al. 2001). Further, sea-ice extent and thickness has recently decreased, permafrost has generally warmed, spring snow extent over Eurasia has been reduced, and there has been a general warming trend in the Antarctic (e.g. Serreze et al. 2000). Most climate models project a sustained warming and increase in precipitation in these regions over the twenty-first century. Projected impacts include melting of ice sheets and glaciers with consequent increase in sea level, possible collapse of the Antarctic ice shelves, substantial loss of Arctic Ocean sea ice, and thawing of permafrost terrain. Such rapid responses would likely have a substantial impact on marine and terrestrial biota, with attendant disruption of indigenous human communities and infrastructure. Further, such changes can trigger positive feedback effects that influence global climate. For example, melting of organic-rich permafrost and widespread decomposition of peatlands might enhance CO2 and CH4 efflux to the atmosphere. Cryospheric researchers are therefore involved in monitoring and documenting changes in an effort to separate the natural variability from that induced or enhanced by human activity.

With the third millennium a new and attractive scenario has opened up, giving voice to an old face of culture: knowledge. Its “new” identity—holistic, multidimensional, and ecosystemic—was highlighted by the European Union in 2000 at the Lisbon conference. In the 21st century there is a star carrying out on its tail these words: welcome to the knowledge society. Knowledge is an immaterial good needed by any nation, because it’s like a bank account that any complex and changing society needs to have. It’s a capital with three faces: economic, social and human (Frabboni, 2006). a. As an economic resource, knowledge promotes a mass-school, a school for everybody: the competitiveness and reliability of a productive system are based on schooling and on the “well-made heads” of younger generations, b. As a social resource it promotes democracy, because knowledge provides all citizens with the necessary alphabets to create a widespread social cohesion; therefore education must be spread during all the seasons of life, from childhood to old age, c. As a human resource it helps the person-subject to move away from the devastating mass-subject. A school of knowledge and of values (i.e., of mind and heart) will have to invest on a person that is nonduplicable, noneasily influenced, and nonuseful; with his or her eyes open on dreams, utopias, and enchantment. School has the task of forming a plural mind and an ethic of solidarity.

While the opportunities offered by technology to people were very limited in the period before 2000, information technology, which is used as a universal means of progress today, has become an indispensable element of the globalizing world by making it easier to access scientific information. With the increasing level of digitalization, there has been a rapid transformation in technology and it has become extremely difficult to keep up with this transformation. In the 21st century, which is accepted as the digital age, the developments in technology have made human life easier on the one hand, and on the other hand have caused the society to become dependent on technology. In the century we have been living in, international economic organizations have rapidly adapted to the developments in technology and the transformation process and have effectively used the advantages provided by technology to themselves. It is seen that international organizations, especially after the Second World War, have taken on extremely important tasks in terms of shaping international markets. Especially in meeting the funding needs of the international market, international economic organizations play an important role. Along with globalization, some international financial institutions such as the World Bank and the International Monetary Fund (IMF) have been significantly affected by recent rapid technological developments. In this context, thanks to the developments in technology, international financial institutions have had the opportunity to transfer the financial resources under their control to the countries or unions in need easily and quickly. Due to this importance, developments in technology are closely monitored by international economic organizations. With this study, it is aimed to examine the development of international economic organizations in the digitalization process and to evaluate the impact of digitalization on the success of international economic organizations by clarifying both positive and negative aspects by data analysis method

The IAEA General Conference in 2000 has invited “all interested Member States to combine their efforts under the aegis of the Agency in considering the issues of the nuclear fuel cycle, in particular by examining innovative and proliferation-resistant nuclear technology”. In response to this invitation, the IAEA initiated an “International Project on Innovative Nuclear Reactors and Fuel Cycles” (INPRO). The overall objectives of INPRO are to help to ensure that nuclear energy is available to contribute in fulfilling in a sustainable manner energy needs in the 21st century, and to bring together all interested Member States, both technology holders and technology users, to consider jointly the international and national actions required to achieve desired innovations in nuclear reactors and fuel cycles that use sound and economically competitive technology. In the first phase of the project the report “Guidance for the evaluation of innovative nuclear reactors and fuel cycles” has been published. (June 2003, IAEA tecdoc 1362, Report of Phase 1A) In the following phase member states are contributing by case studies to validate the methodology for assessment and to evaluate the application of the basic principles, requirements and criteria. The paper will shortly summarize the main findings of the published report in the following fields (a) Prospects and Potentials of Nuclear Power, (b) Economics; (c) Sustainability and Environment, (d) Safety of Nuclear Installations, (e) Waste Management, (f) Proliferation Resistance, (g) Crosscutting issues and (h) the Methodology for Assessment. Further on the paper will deal with the actual phase of INPRO and the ongoing activities.
