King Arthur controlled the climate by decree, similar to the Paris Climate Accord. He must have had very tight control of atmospheric CO2 levels.
The crown has made it clear.
The climate must be perfect all the year.
A law was made a distant moon ago here:
July and August cannot be too hot.
And there’s a legal limit to the snow here
In Camelot.
The winter is forbidden till December
And exits March the second on the dot.
By order, summer lingers through September
In Camelot.
