The Earth's climate is changing in a dramatic way, with immense danger for mankind and the natural systems that sustain it. This was the frightening message broadcast to us by environmentalists in the recent past. Here are some of their prophecies.
The facts have emerged, in recent years and months, from research into past ice ages. They imply that the threat of a new ice age must now stand alongside nuclear war as a likely source of wholesale death and misery for mankind.
(Nigel Calder, former editor of New Scientist, in International Wildlife, July 1975)
The cooling has already killed thousands of people in poor nations... If it continues, and no strong measures are taken to deal with it, the cooling will cause world famine, world chaos, and probably world war, and this could all come about by the year 2000. (Lowe Ponte, The Cooling, 1976)
