Mark Steyn, writing in the Australian, remarks:
One day, the world will marvel at the environmental hysteria of our time, and the deeply damaging corruption of science in the cause of an alarmist cult. The best thing this week’s conference could do is inculcate a certain modesty, not least in Senator Ian Campbell, about an issue that is almost entirely speculative. We don’t know how or why climate changes. We do know it’s changed dramatically throughout the planet’s history, including the so-called “little Ice Age” beginning in 600, when I was still driving a Ford Oxcart, and that, by comparison, the industrial age has been a time of relative climate stability. But, of course, as with that “hockey stick”, it depends how you draw the graph.
Question: Why do most global warming advocates begin their scare statistics with “since 1970”?
As in, “since 1970” there’s been global surface warming of half a degree or so.
Because from 1940 to 1970, temperatures fell.
