Guest essay by David Archibald
It used to be that ocean acidification was the last refuge of the global warming scoundrel. When all else fails – lack of actual warming etc., the global warmers claim that increased carbon dioxide will make the seas acid and dissolve the shells off all the little sea creatures.
The Economist magazine has just gone one further and predicted that it will also cause blight. Hundreds of ludicrous claims have been made about the effect of higher atmospheric CO2 levels on this and that but when The Economist feels the need to join the clamour of idiotic voices then that means something. So, they adopt ‘ludicrous mode‘.

The photo The Economist used to illustrate their article seemingly shows London police wrestling with agitated loons from Extinction Rebellion.
The Economist “tugs at the insecurities and ambitions of the status-seeking reader” who wears “aspirations of wordliness”. In short The Economist instructs its readership of what the proper view on a subject is. What the article means is that the long retreat from global warming alarmism has begun. The magazine’s readership may crave acceptance and be highly susceptible to suggestion but not all would be completely stupid. Thus some would notice colder winters and the fact that the world has hardly warmed at all. And some would be aware that higher atmospheric CO2 levels are beneficial to crop production. And then start thinking that higher atmospheric CO2 levels are all good with no downside. So The Economist comes up with a vague notion about something that might go wrong at an unspecifed time. In effect The Economist is conducting a fighting retreat in the death of the global warming meme.
The truth of the matter is that the plants that most of our diet is derived from, the grasses, evolved when CO2 levels were five times what they are today. The following figure is a screenshot from a presentation by Patrick Moore:
Figure 2: Projected CO2 Level in the Absence of Human Emissions
The Earth’s atmosphere started off at 200,000 ppm CO2. The first plants came along three billion years ago and by 120 million years ago the atmospheric concentration of CO2 was down to one hundredth of its intial level. And then kept falling. If it had kept on that trajectory all life above sea level would have died off from lack of CO2 about five million years from now. Humans evolved just in time to save Creation. That is the inspiring story that should be told, not that there might be blight.
