Grand Solar Minimum Symptoms

There are several lessons learned from studying earlier cycles, and particularly good data on very early global cooling events in Europe. See also specific examples, throughout previous cycles in History.

[IAF Note: I've decorated with some tag links to simplify finding related/recent news corresponding to each of the following:

Onset of these conditions can be very abrupt and very severe.

Food Shortages

A decline in food production for many reasons, including the following.

See also the IAF GSM Crop Loss Map, tracking crop losses related to the new minimum.

Crop Losses

Feed/Grain Shortages for Livestock

  • Lack of feed for livestock (#gsmFood)
  • Parasites (i.e. fusarium nivale), which thrived under snow cover, devastated crops. (#gsmFood)
  • Grain storage in cool damp conditions produced fungus (Ergot Blight). Contaminated grains when consumed caused an illness (St. Anthony’s Fire) producing convulsions, hallucinations, gangrenous rotting of extremities. (#gsmWet)

These lead to major and minor famines.

Geophysical

  • Glacier advance swallowed up entire alpine villages. (#gsmGlacier)
  • Ruptured glacial ice dams produced deadly floods. (#gsmFlood)

Seismic/Volcanic

  • Drastic increase in seismic activity (earthquakes) (#gsmEQ, and
  • Dramatic increase in volcanic activity #gsmVolcano)

Highly Charged Atmosphere

  • Hugely increased atmospheric electric charge (fatal lightning strikes, positive lightning, sprites, noctilucent clouds, northern lights) (#gsmElec)

Wildfires

Wind

  1. Violent, damaging wind events (#gsmWind)

Human/Animal Health: Epidemics

Malnutrition lead to weakened immune system. Environmental conditions from previous plagues recreated. Hence:

  • Influenza epidemics. (#gsmSick)
  • Reoccurrence of plagues such as the Black Plague. (#gsmSick)
  • Flooding created swamplands that became mosquito breeding grounds and introduced tropical diseases such as malaria throughout Europe. (#gsmWet)

I've now done a video on this, I'll add it to GsmSick.

Hail/Storms

  • Extreme atmospheric thermal differentials produced killer hailstorms (hailstones that could kill a cow). (#gsmHail)
  • Higher frequency of powerful storms produced major devastations. (#gsmStorm)

Torrential Rain/Flooding, Droughts

Increase in Cloud Cover

  • Dramatic increase in days with overcast skies. (#gsmDark)
  • Decline in the intensity of sunlight. (#gsmDark)

Cold

  • Decline by several degrees in global temperature (#gsmCold)
