The following is an encore presentation of Everything Everywhere Daily.

In the year 1816, the world experienced something that it had never seen before.

All over the Northern Hemisphere in Europe, Asia, and North America,

Summer never came.

Or at least it didn't in any way which it had before.

It caused chaos and misery all over the world.

Learn more about 1816, the year without a summer,

on this episode of Everything Everywhere Daily. Book your ticket to happiness with Sun Express Airlines. When I say the year 1816 had no summer in the Northern Hemisphere, it obviously was summer as far as the tilt of the Earth and the length of the day goes.

So if the Earth was doing its normal thing, of the earth and the length of the day goes.

So if the earth was doing its normal thing, why was this particular season in this particular

year so different?

It had to do with two unfortunate coincidences which happened to occur at the same time.

One of them was major and one was minor.

The minor event was known as the Dalton Solar Minimum.

I've talked before about Milankovic cycles and how the orbit and tilt of the Earth have several different cycles that it goes through.

The other thing which has cycles is the sun. It goes through periods of solar activity called solar maximums and solar minimums.

During a solar maximum period, which we are just leaving as I'm recording this,

there are more solar flares and sunspots.

During a solar minimum, there's very little solar activity.

These periods tend to go in 11-year cycles

and can influence the Earth's climate,

higher temperatures during solar maximums
