Burying The Lede

It tends to amuse me when the media promote social causes by using stories which “bury the lede,” that is, which ignore points within the story which utterly refute the point which they are trying to make.

“This is the worst drought in 200 years.” To suggest that it is caused by current human activity raising CO2 levels ignores that the worse drought 200 years ago was not caused by current human activity and happened when CO2 levels were lower. Why do we suppose that, not having caused that drought, we did cause this one? The planet has been having droughts for many centuries.

The Anazazi people, who built amazing cities in the cliffs of the Southwest, disappeared somewhere around the 14th century. According to Britannica, “The Great Drought (1276–99) probably caused massive crop failure; rainfall continued to be sparse and unpredictable until approximately 1450,” which contributed to their disappearance. Did the Anazazi people cause that drought, too?

The most recent is the appearance of “Hunger Stones” in the rivers of Europe. These stones have been exposed by river levels dropping to the lowest levels that they have been in centuries. Back then, people carved notes on the stones recording the severe conditions prevailing when the rivers became that dry. One stone dates from the year 1616 and others from the 19th century.

We were probably burning some fossil fuels in the 19th century, but not a hell of a lot. How much fossil fuel were we burning in the year 1616? And yet when the rivers drop to the same level that they did when we were not burning fossil fuel, we blame the drop on the fact that we are burning fossil fuel.

The rivers dry up when the CO2 level is 280ppm, and when they dry up now we claim that they did so because the CO2 level is 420ppm.

To bemoan that something is “the worst it has been since…” is an admission that it has happened before now, that the condition is not unique. It says that the condition existed when your purported cause did not yet exist. For statement of actual systemic disaster attributable to your purported cause one needs, “this is the worst it has ever been,” which we virtually never see.

  1. Each extreme weather event is not by itself evidence for anthropogenic global warming, although they are consistent with AGW. Are you interested in the evidence upon which AGW actually rests?
