Food supplies around the world face collapse if the use of nitrogen fertilizer is severely restricted under Net Zero requirements.
It is claimed that the
fertilizer is warming the Earth and causing the climate to break
down, as the by-product nitrous oxide is released into the
atmosphere.
Political discontent is growing, and there are already fears for the supply of agricultural products since the Netherlands is the second largest food exporter in the world.
Nitrogen is a vital component of plant metabolism which is obtained from the soil. Alas, there is not enough nitrogen in the soil to grow plants at the scale needed to feed global populations.
Before the arrival of commercial nitrogen fertilizers, famine was a frequent feature of the unreliable food supply across parts of the world.
Virtue-signaling green delusions about 'rewilding', bug diets and organic farming will not feed the world, probably not even a quarter of it.
A recent theoretical physics paper from four distinguished scientists said there was evidence that the amount of N2O in the atmosphere, a gas with warming properties, had never been constant over time.
There have been large changes in atmospheric concentrations in inter-glacial periods like the current one. Nitrous oxide is a more powerful 'greenhouse' gas than carbon dioxide, but it accounts for only 0.34 parts per million (ppm), growing at only 0.00085 ppm per year.
Currently CO2 is at 420 ppm, and the molecules are increasing 3,000 times faster in the atmosphere than N2O.
Like all greenhouse gases, its ability to trap heat within narrow bands of the infrared spectrum diminishes after a certain level as the gas becomes 'saturated'.
This helps explain,
After a certain point, any increased warming becomes logarithmic, according to the physicists, meaning it rises ever more slowly in response to additional greenhouse gases, which again provides a plausible explanation as to why temperatures have stayed within a relatively small band across the paleo-record.
Every day seems to bring fresh concerns about the destruction likely to be wrought by the collectivist Net Zero project.
As we have seen in recent articles,
In the view of U.K. FIRES leader Professor Julian Allwood,
The four physicists note that few citizens realize that the effects of N2O on the atmosphere are "negligible".
The proposed burdensome regulations on farming, ranching and dairying,
It is noted that one of the major factors behind the world's "unprecedented" abundance of food in recent years has been the use of mineral nitrogen fertilizer.
One of the authors of the recent report, Professor William Happer of Princeton, recently teamed up with Professor Richard Lindzen of MIT to make clear what a disaster the world faced.
Billions of people around the world faced starvation if the production of nitrogen fertilizer was banned. It would create "worldwide starvation" once half the world does not have enough to eat.
To back up their claims, the authors published the above graph.
This shows clearly the "remarkable" increase in crop yields after the widespread use of nitrogen fertilizer began around 1950.
In his theoretical paper, Happer also notes some of the disasters that have occurred in the past when,
In the Soviet Union, a war on farmers in the 1930s led to millions dying of starvation.
Folk memories of the Golodomor (Holodomor - hunger-murder), when millions of Ukrainians also died at the same time,
Mandates to restrict animal numbers and fertilizer use will dramatically slash agricultural yields.
To continue feeding the world, agricultural areas will have to increase and encroach on native habitats, which could have remained untouched with sensible use of fertilizer.
When even the projected benefit is so negligible, this is a policy with nothing to commend it.
