(6)Glacial retreat:Glaciers are retreating almost everywherearound the world–including in the Alps,Himalayas,Andes, Rockies,Alaska and Africa.(7)Ocean acidification:Since the beginning of the Industrial Rev-olution,the acidity of surface ocean waters has increased by about30%.The amount of carbon dioxide absorbed by the upper layer of the oceans is increasing by about2billion tons per year.The increasing trend of CO2emissions,Arctic sea Ice,CO2con-centration,sea level and global surface temperature is shown in Figs.1–5respectively.September Arctic ice is now declining at a rate of11.5%per decade.Arctic sea ice reaches its minimum in September.The September2010extent was the third lowest in the satellite record.There are lots of initiatives taken by different countries and organizations like United Nations Framework Convention on Cli-mate Change(UNFCCC),United Nations Environment Programme (UNEP)and Intergovermental Panel on Climate Change(IPCC), in mitigating and adapting to the global climate change.The most important mitigation measures include carbon sequestration, clean development mechanism,joint implementation and most880S.VijayaVenkataRaman et

sources.2.Assessing the impacts of climate changeThe ever-increasing emissions of greenhouse gases from various sources has led to catastrophic climate changes including the well pronounced ‘global warming’.Serge Planton et al.gives an overview of the expected change of climate extremes during this century due to greenhouse gases and aerosol anthropogenic emissions like decreasing number of days of frost,increasing growing season length,trends for drought duration and change of wind-related extremes [1].The dramatic change that the arctic has undergone during the past decade including atmospheric sea-level pressure,wind fields,sea-ice drift,ice cover,length of melt season,change in precipitation patterns,change in hydrology,change in ocean cur-rents and watermass distribution were studied by Macdonald et al.[2].The near-surface thermal regime in permafrost regions could change significantly in response to anthropogenic climate warm-ing [3].A scenario of chain of transitions in the solar convective zone was suggested by Bershadskii,in order to explain the obser-vations of increase in sunspots number and a forecast for globalwarming was also suggested on the basis of this scenario [4].With 15case studies in the catchments of UK,Nigel W.Arnell found that the effects of climate change on average annual runoff depend on the ratio of average annual runoff to average annual rainfall,with the greatest sensitivity in the driest catchments with lowest runoff coefficients [5].Hirst examined the response of the Southern ocean to global warming,for a transient greenhouse gas integra-tion using the Commonwealth Scientific and Industrial Research Organisation (CSIRO)coupled ocean–atmosphere model [6].Global warming caused by enhanced greenhouse effect is likely to have significant effects on the hydrology and water resources of the GBM (Ganges,Brahmaputra,Meghna)basins and might ultimately lead to more serious floods in Bangladesh,India [7].Mohammed Fazlul Karim and Nobuo Mimura used a calibrated numerical hydrody-namic model to stimulate surge wave propagation through the rivers and overland flooding,to describe the impacts of climate change namely the sea surface temperature and sea-level rise on cyclonic storm surge flooding in western Bangladesh,India [8].The Asian Pacific Integrated Model (AIM)is a large-scale model for sce-nario analyses of greenhouse gas emissions and the impacts of global warming in the Asian Pacific region.Yuzuru Matsuoka et al.categorized the scenarios that have been written so far in relation to882S.VijayaVenkataRaman et al./Renewable and Sustainable Energy Reviews16 (2012) 878–897global warming and then,givenfixed inputs,simulates the effects of global warming taking in to account various uncertainties using AIM[9].van Minnen et al.presented a new methodology called the “critical climate change”approach for evaluating the policies for reducing climate change impacts on natural ecosystems[10].2.1.Air,water,plants and animalsThe future evolution of the concentration of near-surface pol-lutants determining air quality at a scale affecting human health and ecosystems is a subject of intense scientific research.Robert Vautard and Didier Hauglustaine,based on this thematic issue, reviewed the current scientific knowledge of the consequences of global climate change on regional air quality and its related impact on the biosphere and on human mortality.The changes in the global atmospheric composition,changes in the regional air quality and the organization of the thematic issue of near-surface pollutants that determines the air quality[11].Mooij et al. hypothesized that climate warming and climate-induced eutroph-ication will increase the dominance of cyanobacteria and climate change will also affect shallow lakes through a changing hydrol-ogy and through climate change-induced eutrophication,using two models namely the full ecosystem model PCLake and a min-imal dynamic model of lake phosphorus dynamics[12].Delpla et al.explained the climate change impacts on water quality by reviewing the most recent interdisciplinary literature and con-cluded that a degradation trend of drinking water quality in the context of climate change leads to an increase of at risk situa-tions related to potential health impact[13].Wright et ed the MAGIC model to evaluate the relative sensitivity of several pos-sible climate-induced effects on the recovery of soil and surface water from acidification and suggests that the future modeling of recovery from acidification should take in to account possible cli-mate changes and focus especially on the climate-induced changes in organic acids and nitrogen retention[14].A simple methodol-ogy for assessing the salination risk for any water management situation and under global warming conditions was presented by Angel Utset and Matilde Borroto,where the physically based SWAP (Soil–Water–Atmosphere–Plant environment)model was used to predict future water table depths after irrigation begins and under global warming conditions[15].Estimating the impacts of climate change on ground water represents one of the most difficult chal-lenges faced by the water resource specialists.Pascal Goderniaux et al.provided an improved methodology for the estimation of the impacts of climate change on groundwater reserves,where a phys-ically based surface–subsurfaceflow is combined with advanced climate change scenarios for the Geer basin,Belgium usingfinite element model‘HydroGeoSphere’[16].The change in climate is likely to have a profound effect on hydrological cycle viz.precip-itation,evapotranspiration and soil moisture,evapotranspiration (ET)being the major component of hydrological cycle will affect crop water requirement and future planning and management of water resources.An attempt has been made by Goyal to study the sensitivity of ET to global warming for arid regions of Rajasthan, India.Weekly reference evapotranspiration was calculated using the Penman–Monteith method and the study revealed that even as small as1%increase in temperature from base data could result in an increase in evapotranspiration by15mm,which means an addi-tional water requirement of34.275mcm for Jodhpur district alone and313.12mcm for whole arid zone of Rajasthan.The increased evapotranspiration demand due to global warming can put tremen-dous pressure on existing overstressed water resources of this region and since this region is devoid of any perennial river system, any increase in water demand requires careful planning for future water resource development in this region.The study provided a contemporary view on future water requirement of this region in context of global warming[17].With the global climate change data provided by the IPCC from thefirst version of the Canadian Global Coupled Model(CGCMI),GIS based EPIC is run by Guoxin Tan and Ryosuke Shibasaki,for scenarios of future climate in the year of2010,2020,2030,2040and2050to predict the effects of global warming on main crop yields and the results showed that the global warming will be harmful for most of the countries and an efficient adaptation to alternative climates tends to reduce the damages[18].Goudie outlined that future global warming has a number of implications for‘fluvial geomorphology’because of changes in such phenomena as rates of evapotranspiration,precip-itation characteristics,plant distributions,plant stomatal closure, sea levels,glacier and permafrost melting and human responses [19].Saving tropical forests as a global warming counter–mea-sure has become one of the environment’s most divisive issues, according to Fearnside[20].The impacts of GHG emissions on for-est ecosystems have been traditionally treated separately for air pollution and climate change.Andrzej Bytnerowicz et al.reviewed the links between air pollution and climate change and their inter-active effects on northern hemisphere forests[21].Range limits of many plant species are expected to shift dramatically if climate warming,driven by the release of GHG,occurs in the next century. Simulation models are presented by Dyer,which incorporate two factors,land-use pattern and means of dispersal,to assess poten-tial responses of forest species to climate warming[22].Wildlife managers face the daunting task of managing wildlife in light of uncertainty about the nature and extent of future climate change and variability and its potential adverse impacts on wildlife.Tony Prato developed a conceptual framework to manage wildlife under such uncertainty,which uses a fuzzy logic to test hypotheses about the extent of the wildlife impacts of past climate change and vari-ability and fuzzy multiple attribute evaluation to determine best compensatory management actions for adaptively managing the potential adverse impacts of future climate change and variability on wildlife[23].2.2.EconomyThe impacts of GHG emissions and the resulting climate change have a serious impact on the global economy.The Futures of Global Interdependence(FUGI)global modeling system has been developed as a scientific policy simulation tool of providing global information to the human society andfinding out possibilities of policy coordination among countries in order to achieve sustain-able development of the global economy under the constraints of rapidly changing global environment.The FUGI global model M200classifies the world into200countries/regions where each national/regional model is globally interdependent through oil prices,energy requirements,international trade,export/import prices,financialflows,ODA,private foreign direct investment, exchange rates,stock market prices and global policy coordination, etc.Akira Onishi studied the futures of global economy under the constraints of energy requirements and CO2emissions up to2020 as well as strategy for sustainable development of the interdepen-dent global economy.In order to cut back global CO2emissions,it is necessary to confront dilemma of sustainable development of the global economy.A surprising proposal made by limits to growth (1972)is zero growth of the global economy.If the global economy will confront with zero growth,it seems likely to induce global crises such as Great Depression in1930s.Zero growth may cutback CO2emissions but could not solve trade-off between environment issues and desirable development of the global economy.Alternative simulation by FGMS(FUGI global modeling system) revealed that cutbacks of global CO2emissions should be pre-requisite against global warming.In order to cutback global CO2 emissions,it should be needed for international co-operation andS.VijayaVenkataRaman et al./Renewable and Sustainable Energy Reviews16 (2012) 878–897883co-ordination of development strategy.Even if EU and Japan will co-operate and co-ordinate the policies toward cut back of CO2 emissions by technology innovations for developing alternative energy and energy savings,it could not achieve the global targets without co-operation with the major CO2emission nations such as US,China,Russian Federation.In order to decrease global CO2emis-sions,the developing countries should join as a group and should promote official development assistance(ODA),in particular,tech-nical co-operation to the developing countries.Technology transfer from the advanced to developing countries are pre-requisite for achieving the target of cut back global CO2emissions.Advanced economies should make utmost efforts to increase R&D as well as investments for alternative energy and energy savings.The FUGI global model simulations affirmed that not only increased R&D together with investments will increase rates of development of global economy but also decrease global CO2emissions[24].Evi-dence of the impacts of anthropogenic climate change on marine ecosystems is accumulating,but must be evaluated in the context of the“normal”climate cycles and variability which have caused fluctuations infisheries throughout human history.The impacts onfisheries are due to a variety of direct and indirect effects of a number of physical and chemical factors,which include tem-perature,winds,vertical mixing,salinity,oxygen,pH and others. The direct effects act on the physiology,development rates,repro-duction,behavior and survival of individuals.Indirect effects act via ecosystem processes and changes in the production of food or abundance of competitors,predators and pathogens.Keith Bran-der reviewed the recent studies of the effects of climate on primary production and evaluated the consequences forfisheries produc-tion through regional examples namely North Atlantic,Tropical Pacific Antartic and Lake Tanganyika.Regional examples namely North Sea,Baltic and North Atlantic are also used to show changes in distribution and phenology of plankton andfish,which are attributed to climate.The role of discontinuous and extreme events (regime shifts,exceptional warm periods)was also discussed[25]. Harle et al.made a study on the implications of climate change on the Australian wool industry,principally through on forage and water resources,land carrying capacity and sustainability,animal health and competition with other sectors,particularly cropping [26].Maria Berrittella et al.studied the economic implications of climate change-induced variations in tourism demand,using a world Computable General Equilibrium(CGE)model.The model wasfirst re-calibrated at some future years,obtaining hypotheti-cal benchmark equilibria,which were subsequently perturbed by shocks,simulating the effects of climate change.The impact of cli-mate change on tourism was portrayed in this study by means of two sets of shocks,occurring simultaneously.Thefirst set of shocks translates predicted variations in touristflows into changes of consumption preferences for domestically produced goods.The second set reallocate income across world regions,simulating the effect of higher or lower tourists’expenditure.The analysis high-lights that variations in touristflows will affect regional economies in a way that is directly related to the sign and magnitude of flow variations.At a global scale,climate change will ultimately lead to a welfare loss,unevenly spread across regions.Despite the crude resolution of the analysis made,which hides many climate change-induced shifts in tourist destination choices,it was found that climate change may affect GDP by−0.3–0.5%in2050.Eco-nomic impact estimates of climate change are generally in the order of−1–2%of GDP for a warming associated with a dou-bling of the atmospheric concentration of carbon dioxide,which is typically put at a later date than2050.As these studies exclude tourism,this implies that regional economic impacts may have been underestimated by more than20%.The study indicates that the global economic impact of a climate change-induced change in tourism is quite small,and approximately zero in2010,but in2050,climate change will ultimately lead to a non-negligible global loss [27].Susanne Becken analyzed the adaptation to climate change by tourist resorts in Fiji,as well as their potential to reduce climate change through reductions in CO2emissions[28].Koetse and Piet Rietveld presented a survey of empirical literature on the effects of climate change on the transport sector and the net impact on generalized costs and economy of various transport modes are dis-cussed[29].Radu Zmeureanu and Guillaume Renaud presented a method for the estimation of climate change on the economy of the heating energy use of existing houses[30].2.3.AgricultureRobert Mendelsohn examined the likely impact on agriculture of the climate change which has already taken place between1960 and2000,when the global temperature rise was0.25◦C,causing the precipitation patterns to shift and the cross-sectional and crop simulation evidence,temperature,precipitation and CO2response functions are used to calculate the impacts on agriculture[31]. The implications for agriculture of mitigating GHG emissions and by when and by how much are the impacts reduced was inves-tigated by Tubielloa and Gunther Fischera and it was found that mitigation could positively impact agriculture[32].Bernard Tin-ker et al.addressed the questions of to what extent slash and burn of agriculture is responsible and how land conversion of this type will affect the climate system,including its impact on local and regional hydrology[33].Rivington et al.argued that an Integrated Assessment(IA)approach,combining simulation mod-eling with deliberative process involving decision makers and other stakeholders,has the potential to generate credible and relevant assessments of climate change impacts on farming systems[34]. Chakraborty et al.found that,despite the significance of weather on plant diseases,comprehensive analysis of how climate change will influence plant diseases that impact primary production in agricul-tural systems is presently unavailable and improvements to assess disease impacts is mandatory[35].Trudie Dockerty et al.explored the possibility of interpreting climate change impacts information of agricultural landscape in Norfolk through GIS based visualiza-tions[36].Gunther et al.investigated the potential changes in global and regional agricultural water demand within a new socio-economic scenario,A2r,developed at the International Institute for Applied System Analysis(IIAS)with and without climate change, with and without mitigation of GHG emissions[37].Despite the importance of livestock to poor people and the magnitude of the changes that are likely to befall livestock systems,the intersec-tion of climate change and livestock in developing countries is a relatively neglected research area.Little is known about the interac-tions of climate and increasing climate variability with other drivers of change in livestock systems and in broader development trends. In many places in the tropics and subtropics,livestock systems are changing rapidly,and the spatial heterogeneity of household response to change may be very large.Thornton et al.briefly reviewed the literature on climate change impacts on livestock and livestock systems in developing countries.The impact of climate change on livestock in terms of quantity and quality of feeds,heat stress,water,livestock diseases and vectors,biodiversity and sys-tems and livelihoods were studied.For instance,while the response of livestock to known increases in temperature is predictable,in terms of increased demand for water,attempts to quantify the impacts of climate change on water resources in the land-based livestock systems in developing countries are fraught with uncer-tainty,particularly in situations where groundwater accounts for a substantial portion of the supply of water to livestock,which is the case in many grazing systems.In addition to the direct impacts of a changing climate on many aspects of livestock and livestock systems,there are various indirect impacts that can be expected to。
