Hey, I Tried to Warn You About Climate Change 30 Years Ago!

Even the Pentagon is worried about climate change, and warned it could exacerbate the threat of terrorism, we learned in a report this week. And in the hot Florida governor's race, the increase in flooding in some areas has become a campaign issue -- and in Kentucky and other states, as well.

Jon Stewart had some fun last night with "Fan-gate" in the Florida governor's race but maybe eveyrone there will need 24-hour fanning any year now.

I've never thought of myself of a pioneer in warning about climate change, but maybe, just a little.

Back in 1984, Viking published a book I wrote with Pascal J. Imperato, titled Acceptable Risks, which examined how regulators, and individuals, choose to ignore certain hazards -- such as smoking or living in earthquake-prone California -- while taking action against others, often in a highly irrational way. The penultimate chapter, actually written in 1982, explored a just-emerging danger we called "The Ultimate Risk: The Greenhouse Effect."

This is what it was called before it was referred to as "global warming," and then more accurately and broadly, "climate change." Back in the good old days we figured we still had plenty of time to address it. In that period, nuclear threat was the prime concern.

Recently I decided to check back on that chapter, which I penned myself in 1983, for the first time in a few years. What I found: There's not much new under the ever-hotter sun. The "inconvenient truth" of global warming has been told for decades -- Dr. James Hansen was featured in our chapter -- to little avail. Ironically, I had interviewed the young congressman, Al Gore, for my previous book on whistleblowers, related to toxic dump sites.

In fact, the chapter in Accepable Risks opens with a warning about the Antarctic ice sheet melting, and a rising of the sea level likely to "submerge" coastal cities. The paragraph that followed could have come directly from the famous Al Gore film (without the slide show) 20 years on:

"There have been warming trends before, but never one so rapid as this -- virtually overnight on the geological clock. Rather than having several hundreds years to cope with the changes it may bring, humankind will have to adjust in little more than half a century."

Of course, we are now 30 years into that half-century.

"More than a severe disruption of the world economy is at stake," I wrote. "The very survival of Earth's highest forms of life may be on the line." But, I advised, "Something can be done to prevent -- or at least mitigate -- this threat. On a global basis, humankind can cut down its burning of fossil fuels, stabilizing the excessive accumulation of carbon dioxide in the earth?s atmosphere that creates the hazard known as the Greenhouse Effect."

"There is no sign, however, that we have the slightest interest in doing this."

Back then, scientists felt sure the warming would soon come -- they accurately projected a one degree global rise in 20 years -- but that normal temperature cycles were probably masking the trend, and "the lack of clear-cut evidence for a major warming effect may have terrible consequences, for it has already undermined efforts at getting governments of the world's nationals to deal with the threat of such an effect."

So what was our own Congress doing about it then? About as much as it is now. But there was sort of an excuse. Climate change, as noted, was still somewhat speculative. One top scientist told me, "To really KNOW anything you?ll have to wait another thirty years, so we won't be able to convince Congress of anything until 2010."

As it turned out, we came to know a lot long before thirty years passed. As Leonard Cohen once put it, "We asked for signs/and signs were sent." But about that 2010 deadline...
