Corn is the latest grocery item to reportedly suffer from a “coronavirus-related shortage” — and serving as anecdotal evidence of the bare supermarket shelves, a number of chains in both Portugal and the UK haven’t had any stocked for months.
The paper goes on to reference both the Maunder and Dalton Minimums, and the human struggles witnessed then. It also mentions Svensmark et al., 2017’s proposition that “increased ionization produced by cosmic rays (during low solar activity) leads to growth aerosols into cloud condensation nuclei. This mechanism suggests increased cloud cover as the sun enters a grand solar minimum” — I see this as being one of the main drivers of the cooling and also the observed increase in localized precipitation.
