WhatIsClimateChange?

Theplanet'sclimateisconstantlychanging.Theglobalaveragetemperatureiscurrentlyintheregionof15℃.Geologicalandotherevidencesuggeststhat,inthepast,thisaveragemayhavebeenashighas27℃andaslowas7℃.

Butscientistsareconcernedthatthenaturalfluctuation(波動)hasbeenovertakenbyarapidhuman-inducedwarmingthathasseriousimplicationsforthestabilityoftheclimateonwhichmuchlifeontheplanetdepends.

WhatIsthe"GreenhouseEffect"?

ThemajorityofclimatescientistsacceptthetheorythatanincreaseinthesegaseswillcauseariseintheEarth'stemperature.

WhatIstheEvidenceofWarming?
