Below is a 700.000-year temperaturerecord prepared by marine geologistCesare Emihani of the University ofMiami. The ratio of the two oxygen iso-topes in seashells has been found tovary with water temperature and thismade it possible for Emiliam to calcu- late ancient water temperatures fromfossils in the sediment layers In theCaribbean The chart shows a regularsuccession of maior ice ages at inter-vals of about 100.000 years Withinthese cycles, spells of relative coolnessand warmth alternate at roughly 20.000-year intervals The calculations indicatethat the 6.000 years of civilizationhave coincided with the warmest tem-peratures m nearly 100 000 years In- T ©mpor aturo through gaofogical Hint) \y-vk^\NW^-JKJ^ ; 700,000 600,000 500,000 400.000 300.000 200.000 100.000 FORTUNE ftnjtry I97< 01 CRS-173
