The IPCC has three working groups that assess different aspects of climate change. Working Group I assesses the physical scientific basis of climate change. Working Group II assesses the impacts of climate change on human and natural systems, as well as vulnerabilities and adaptation options. Working Group III assesses options for mitigating climate change through limiting greenhouse gas emissions. Each working group is led by co-chairs and contributes to the IPCC's comprehensive assessment reports on understanding climate change, its impacts and responses.

INTRODUCTION OF IPCC
I.INTRODUCTION:
The IPCCjointlyestablishedby WorldMeteorological Society/Oraganization(WMO) andthe
UnitedNationEnvironmentProgramme(UNEP) in1988,the IntergovernmentalPanel onClimate
Change’s(IPPCC) mandate/objective is“toprovide the worldwithaclearscientificview onthe current
state of knowledgeinclimate change anditspotential environmentalandsocio-economicimpacts”.
The IPPCCis an organizationof governmentsthatare membersof the UnitedNationsorWMO. The
IPPCCcurrentlyhas195 members.
The unique powerof thisUN climate bodylies inthe breadthanddepthof itsclimate

2. DISCUSSION:
What is IntergovernmentalPanel onClimateChange orIPPCC?
IntergovernmentalPanel onClimateChange(IPCC)- isthe unitedNationbodyforassessingthe
science relatedtoclimate change.
The IPCC jointlyestablishedbyWorldMeteorological Society/Oraganization(WMO)
and the UnitedNationEnvironmentProgramme(UNEP) in1988,the IntergovernmentalPanel on
Climate Change’s(IPPCC)mandate/objective is“toprovide the worldwithaclearscientificview

economicimpacts”.
The IPPCCis an organizationof governmentsthatare membersof the UnitedNationsorWMO.

What is the role of IPCC?
 To assesson a comprehensive, objective, openandtransparentbasisthe scientific,
technical andsocio-economicinformationrelevanttounderstandingthe scientificbasis
of riskof human-inducedclimate change,itspotentialimpactsandoptionsforadaptation
and mitigation.
“IPPCCreportsshouldbe neutral withrespecttopolicy, althoughtheymayneedtodeal
objectively withscientific,technical andsocio-economicfactorsrelevanttothe applicationof
particularpolicies.”
REFLECTION:
The IPCC isveryhelpful tous,theyare the one whoassessthe science relatedto
climate change.Throughitsassessments,the IPCCdeterminesthe state of knowledge onclimate
change.Maybe we can helptoslowthe rapidnessof global warmingby reducingourgarbage
and separate them a bio-degradable andnon-biodegradablematerials.

4. THE THREE WORKING GROUPS OF IPCC
I. Introduction:
The IPCCworkis sharedamongthree WorkingGroups,a Task Force and a Task
Group. The activitiesof eachWorkingGroupand of The Task Force are coordinatedbya
Technical SupportUnit(TSU).
The IPCCWorkingGroup I(WGI) aimsat assessingthe physical scientificbasisof
the climate change.
The IPCCWorkingGroup II(WGII) assessesthe vulnerabilityof soci-economicand
natural systemstoclimate change.
The IPCCWorkingGroup IIIassesses optionsformitigatingclimate change
throughlimitingorpreventinggreenhousegasemissions.
II. Discussion:
WorkingGroup I dealingwith the Physical science basisof climate change.
Scientistsall overthe worldregularlyassessthe richbodyof scientificliterature,contributing
to an ever-strengtheningunderstandingof how the climate systemworks,andhow itis
changinginresponse tohumanactivity.
The scientifictopicsassessedbyWGIinclude:greenhouse gasesandaerosolsinthe
atmosphere;temperature changesinthe air,landandocean;the hydrological cycle and
changingprecipitation(rainandsnow) patterns;extreme weather;glaciersandice sheets;
oceansand sealevel;biogeochemistryandthe carboncycle;and climate sensitivity.The WGI
assessmentcombinesobservations,palaeoclimate,processstudies,theoryandmodellinginto
a complete picture of the climate systemandhow itischanging,includingthe attribution(or
causes) of change.
The WGI assessmentprovidesscientificinformationrelevantforthe global communityto
meetthe challenge of climate change.Aswell asthe global scale,WGIlooksat variabilityand
changeshappeningata regional level,whichiscloselytiedtohow impactsandrisksto human
and natural systemsare changingovertime.Thisis,inturn,relatestothe assessmentof WGII
and the needtodesigneffective climate change adaptationpolicies.Otherimportantpolicy
dimensionsof WGIare the assessmentof the amountof carbon emissionscompatible with
climate andenergytargets;interactionsbetweenlandandthe climate;andlinksbetween
climate andair quality.All of these aspectsare closelyconnectedwiththe assessmentof
WGIII andstrategiestomitigate againstthe impactsof climate change.

5. Workinggroup II dealingwithImpacts, adaptation and vulnerability.
The IPCC WorkingGroupII (WGII) assessesthe impactsof climate change,fromaworld-widetoa
regional viewof ecosystemsandbiodiversity,andof humansandtheirdiverse societies,culturesand
settlements.Itconsiderstheirvulnerabilitiesandthe capacitiesandlimitsof thesenatural andhuman
systemstoadapt to climate change andtherebyreduce climate-associatedriskstogetherwithoptions
for creatinga sustainable futureforall throughanequitable andintegratedapproachtomitigationand
adaptationeffortsatall scales.
WorkingGroup IIis ledbytwo Co-ChairsandeightVice-Chairswhichformthe WGIIBureau.WGII is
supportedbya Technical SupportUnit(TSU) locatedinBremen,Germany,andDurban,SouthAfrica.
WorkingGroup III dealingwiththe mitigationof climate change. Climate change mitigationis
achievedbylimitingorpreventinggreenhousegasemissionsandbyenhancingactivitiesthatremove
these gasesfromthe atmosphere.Greenhousegasescancome froma range of sourcesandclimate
mitigationcanbe appliedacrossall sectorsandactivities.These includeenergy,transport,buildings,
industry,waste management,agriculture,forestry,and otherformsof landmanagement.
WorkingGroup IIIsupportsthe IPCC’ssolution-orientedapproachbutdoesnotadvocate anyspecific
mitigationoptions.Ittakesbotha near-termperspective relevanttodecision-makersingovernment
and the private sectoranda long-termperspective thathelpsidentifyhow high-level climate policy
goalsmightbe met.WorkingGroup IIIaddressesall aspectsof mitigationincludingtechnical feasibility,
cost and the enablingenvironmentsthatwouldallow measurestobe taken up.Enablingenvironments

6. III.REFLECTION:
If we can’t dosomethingtoour motherearth,ourfuture generationwill be miserable.
That’s whythese three workinggroups determine the physical sciencebasis,the impacts,adaptation
and vulnerabilityandmitigationof climate change.The IPCCcreate these groupstolearnthe climate

efficientmodels.we cancounterbalance ourannual carbondioxideemissionsbyinvestingin
commercial servicesthatdrawdownanequal amountof carbon out of the atmosphere,suchas
