Lets go back to the 70's shall we? Gerald Ford is president, Saigon falls, Hoffa disappears, and in climate science, evidence points to catastrophic cooling and a new ice age. Such fears had been building for many years. In the first Earth Day in 1970, UC Davis's Kenneth Watt said, "If present trends continue, the world will be about four degrees colder in 1990, but eleven degrees colder by the year 2000. This is about twice what it would take to put us in an ice age." International Wildlife warned "a new ice age must now stand alongside nuclear war" as a threat to mankind. Science Digest said "we must prepare for the next ice age." The Christian Science Monitor noted that armadillos had moved out of Nebraska because it was too cold, glaciers had begun to advance, and growing seasons had shortened around the world. Newsweek reported "ominous signs" of a "fundamental change in the world's weather."
But in fact, every one of these statements was wrong. Fears of an ice age had vanished within five years, to be replaced by fears of global warming. These fears were heightened because population was exploding. By 1995, it was 5.7 billion, up 10% in the last five years. But in reality, in the 70, manufacturing and industry was not at all environmentally aware and did nothing to reduce their "impact" on the environment. Yet, still the temperatures dropped. There were tons of cars, gas guzzling muscle cars. Nower days industry takes precautions to lessen their impact and we have hybrids, and yet the temp is somehow rising? Is it so far fetched to say this is all a natural phenomena the plant does on its own?
