Full Quote: For the past 25 to 30 years the Earth has been getting progressively cooler again. Around 1960 the cooling was particularly sharp. And there is by now widespread evidence of a corresponding reverse in the ranges of birds and fish and the success of crops and forest trees near the poleward and altitudinal limits. ~ The United Nations Educational, Scientific and Cultural Organization Courier
