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

ThemajorityofclimatescientistsacceptthetheorythatanincreaseinthesegaseswillcauseariseintheEarth'stemperature.
