**Introduction**
Globalwarminghasbecomeoneofthemostpressingissuesfacinghumanitytoday.Asindustrializationacceleratesandhumanactivitiesexpand,theEarth'sclimatesystemisundergoingunprecedentedchanges.Theincreaseingreenhousegasemissions,deforestation,andunsustainableresourceexploitationhaveledtoasteadyriseinglobaltemperatures,triggeringextremeweatherevents,risingsealevels,andecologicalimbalances.Thisphenomenonisnotmerelyanenvironmentalproblembutaglobalcrisisthatdemandsimmediateattentionandcollectiveaction.

Theprimarycauseofglobalwarmingliesintheexcessiveemissionofgreenhousegases,particularlycarbondioxideandmethane,intotheatmosphere.Theburningoffossilfuelsforenergyproduction,transportation,andmanufacturinghassignificantlyincreasedcarbondioxidelevels,trappingheatanddisruptingtheEarth'snaturaltemperatureregulation.Additionally,thelarge-scaledeforestationforagriculturalexpansionandurbandevelopmenthasreducedtheplanet'scapacitytoabsorbcarbondioxide,exacerbatingtheproblem.AccordingtotheIntergovernmentalPanelonClimateChange(IPCC),humanactivitiesaccountforover90%oftheobservedwarmingsincethemid-20thcentury.Thesefactsunderscoretheurgentneedtoaddresstherootcausesofclimatechange.
