Determinants of Access and Utilization of Climate Services Among Vulnerable Communities

Changes in climate have caused impacts on natural and human systems. These impacts affect poor people's lives through impacts on livelihoods and the destruction of homes. In Delta State, Nigeria, the impacts of climate change are real. Adaptation has been identified as the key to reducing the impacts of climate change. However, successful adaptation depends on use of climate services. While climate services are essential to adaptation, the services do not always reach the users who need it most. This chapter analyzes factors influencing access and utilization of climate services in Delta State. The chapter utilizes the survey research while data were analyzed using both descriptive and inferential statistics. Findings show a low utilization of climate service. The determinants of access and utilization of climate services include income, educational attainments, access to ICT facilities, extension agents, and the level of local climate variability. The chapter calls for awareness creation on the importance of climate services.

GLOBAL WARMING – PHYSICS AND GEOPOLITICS (Review). 4. Climate service in energy

Introduction. Reducing the negative impact of global warming on the economy and adapting to its devastating effects remains an important global challenge. Its solution is actively taken care of by politicians, the world's leading scientific organizations and the expert community. Problems. Economic, innovative and social approaches and measures to reduce and / or neutralize climate change, as well as adaptation to warming are considered. A new direction has been formed - climate service of world energy. Goal. Assess the state of the problem, present measures and tools for their implementation to reduce greenhouse gas emissions and / or adapt to their negative impact, in particular, in the field of energy using the GFCS approaches. Materials and methods. Authoritative recent literature sources with analysis of approaches, measures and tools to reduce greenhouse gas emissions have been used. Results. The experience on development and use of innovative technologies of climatic service in power on the basis of GFCS is resulted. Conclusions. Undoubtedly, the physics and geopolitics of global warming have become one of the most pressing transdisciplinary problems in the realities of the modern world. It is necessary to develop and deepen the scientific basis for the adaptation of life and economy to possible climate change and its consequences. It is important to change the behavior of society in an adequate attitude to the comfortable living conditions, in particular to its energy supply, and in general to a careful attitude to world resources, for example, on the basis of consistent implementation of the principles of sustainable development

Global Climate Services: A Typology of Global Decisions Influenced by Climate Risk

Climate services are ideally co-developed by scientists and stakeholders working together to identify decisions and user needs. Yet, while climate services have been developed at regional to local scales, relatively little attention has been paid to the global scale. Global climate services involve decisions that rely on climate information from many locations in different world regions, and are increasingly salient. Increasing interconnections in the global financial system and supply chains expose private companies and financial institutions to climate risk in multiple locations in different world regions. Further, multilateral decisions on greenhouse gas emission reduction targets, disaster risk finance or international migration should make use of global scale climate risk assessments. In order to advance global climate service development, we present a typology of decisions relying on global (i.e., non-local) climate risk information. We illustrate each decision type through examples of current practice from the coastal domain drawn from the literature and stakeholder interviews. We identify 8 types of decisions making use of global climate information. At a top-level, we distinguish between “multilateral climate policy decisions,” and “portfolio decisions involving multiple locations.” Multilateral climate policy decisions regard either “mitigation targets” or “multilateral adaptation” decisions. Portfolio decisions regard either “choice of location” or “choice of financial asset” decisions. Choice of location decisions can be further distinguished as to whether they involve “direct climate risks,” “supply chain risks” or “financial network risks.” Our survey of examples shows that global climate service development is more advanced for portfolio decisions taken by companies with experience in climate risk assessment, i.e., (re-)insurers, whereas many multilateral climate policy decisions are at an earlier stage of decision-making. Our typology thus provides an entry-point for global climate service development by pointing to promising research directions for supporting global (non-local) decisions that account for climate risks.

Verification and Bias Adjustment of ECMWF SEAS5 Seasonal Forecasts over Europe for Climate Service Applications

This work discusses the ability of a bias-adjustment method using empirical quantile mapping to improve the skills of seasonal forecasts over Europe for three key climate variables, i.e., temperature, precipitation and wind speed. In particular, the suitability of the approach to be integrated in climate services and to provide tailored predictions for local applications was evaluated. The workflow was defined in order to allow a flexible implementation and applicability while providing accurate results. The scheme adjusted monthly quantities from the seasonal forecasting system SEAS5 of the European Centre for Medium-Range Forecasts (ECMWF) by using ERA5 reanalysis as reference. Raw and adjusted forecasts were verified through several metrics analyzing different aspects of forecast skills. The applied method reduced model biases for all variables and seasons even though more limited improvements were obtained for precipitation. In order to further assess the benefits and limitations of the procedure, the results were compared with those obtained by the ADAMONT method, which calibrates daily quantities by empirical quantile mapping conditioned by weather regimes. The comparable performances demonstrated the overall suitability of the proposed method to provide end users with calibrated predictions of monthly and seasonal quantities.

C3S Energy: an operational service to deliver power demand and supply for different electricity sources, time and spatial scales over Europe

The EU Copernicus Climate Change Service (C3S) has produced an operational climate service, called C3S Energy, designed to enable the energy industry and policy makers to assess the impacts of climate variability and climate change on the energy sector in Europe. The C3S Energy service covers different time horizons, for the past forty years and the future. It provides time series of electricity demand and supply from wind, solar photovoltaic and hydro power, and can be used for recent trends analysis, seasonal outlooks or the assessment of climate change impacts on energy mixes in the long-term.This paper introduces this dataset, with a focus on the design and validation of the energy conversion models, based on ENTSO-E energy data and the ERA5 climate reanalysis. Flexibility and coherence across all countries have been privileged upon models’ accuracy. However, the comparison with ENTSO-E data shows that the models provide plausible energy indicators and, in particular, allow to compare climate variability effects on power demand and generation in an homogenous approach all over Europe.
