Fertilizing the air with carbon dioxide to promote plant growth
ONE of the principal constituents making up the body of a plant is carbon, representing about one-half of its organic substance. The opinion that this carbon is derived from the soil has long been abandoned, modern investigation having shown atmospheric carbonic acid to be absorbed by means of the chlorophyll or green matter of the leaves and decomposed into its elements, the carbon, in conjunction with the root sap and atmospheric moisture, being worked into organic compounds.
Whereas atmospheric air at present is relatively poor in carbonic acid, of which it contains only about .03 per cent, at an early period in the development of our planet, when this was covered with the luxuriant forests our coal deposits are derived from, it comprised incomparably greater quantities of this gas. This fact suggested the idea of heightening the fertility of the soil by increasing its carbonic acid content and thus producing conditions resembling those of antediluvian ages.
Now they say -
Climate change's negative effects on plants will likely outweigh any gains from elevated atmospheric carbon dioxide levelsIn the 1920 article, they provide tens of millions of years of empirical evidence - luxuriant forests growing at much higher CO2 levels, but now they completely disregard the scientific method, throw all evidence out the window, and make nonsensical speculations based on climate models.

In the past 5 years and particularly in the past year since the madness this once proud magazine had been totally corrupted into a woke fear-mongering pile of shit. I'm keeping the latest issues in spite of my sheer disgust simply for historical reference.
All of these wokester/CIA editors were in place in the majority of English technical and medical journals before the covid madness was sprung.
The planning for this must have been decades in the making.
