In summary, the author of this article believes that the European climate deteriorated after about the year 1000 due to a lack of sun spots.

Since the publication of Ladourie's Histoire de climat depuis
l'an mil in 1967, historians have generally accepted that the
European climate deteriorated after about the year 1000. They
have seen this deterioration as a cause of the Great Famine of
1315-1317, a factor the Black Death of 1347, and contributing to
the depression of the fifteenth century. There has been little
demand for a more precise chronology, and even less for a cause.
Since it was noted that there were few sun spots during the
period, and since someone coined the term, "The Era of the Quiet
Sun," historians have been more or less content to accept a lack
of solar storms somehow caused the deterioration of the medieval
European climate.

Is this an accurate work ?

Not really but the "best-before.." date of articles like this is only to the refuting discovery. However, in the abstact we see already a problem:

Since it was noted that there were few sun spots during the
period, and since someone coined the term, "The Era of the Quiet
Sun,"

The reason why nobody noticed sunspots was because they were not really discovered/registered, apart from some haphazard observations:

The first one to observe the sun in a continuous way was the Dutch J.Fabricius. His book " de Maculis in Sole" (1611) is the first ever published on observation of sunspots.

The known period, practivally without sunspots, is know as the maunder minimum (1645 and 1715) with clear climatal clues:

The latest paper with a reconstruction of sunspot counts and climatal response is here:

Thanks Andre, you really are a mine of information, Ken Dodd would be proud :biggrin:

Kenn Dodd? Am I that ..em..tattifilarious? :tongue:

I am sure he would have welcomed you to his jam buttie mines in knotty Ash
any time. :biggrin:
The study of history and climate change seem to go hand in hand, the more one
reads the more it seems a natural variation, i wonder how many think that our
sun is not thermostaticaly controlled ?
 

1. What is the Aurora of 1192 and why is it significant in medieval Europe?

The Aurora of 1192 refers to a prolonged and intense display of the Northern Lights that occurred in Europe in the year 1192. This event is significant because it was one of the earliest recorded instances of the Northern Lights in medieval Europe, and it has been linked to a significant climate change event.

2. How do scientists study climate change in medieval Europe?

Scientists study climate change in medieval Europe by examining historical records, such as written chronicles, diaries, and artwork, as well as natural proxies like tree rings and ice cores. These sources provide valuable information about past climate conditions and changes.

3. What evidence suggests that the Aurora of 1192 was caused by a climate change event?

The intense and prolonged display of the Northern Lights in 1192 was recorded by multiple sources, including Chinese and European chroniclers. Additionally, studies of tree rings and ice cores from the same time period show evidence of a significant climate anomaly, indicating that the Aurora was likely caused by a change in Earth's climate.

4. How did the climate change event of 1192 impact medieval Europe?

The climate change event of 1192 is believed to have led to colder and wetter conditions in Europe, resulting in crop failures, famine, and social unrest. It also had a significant impact on trade and travel, as harsh weather conditions made it difficult for ships to navigate and roads to be traversed.

5. What can we learn from studying the Aurora of 1192 and medieval Europe's climate change?

Studying the Aurora of 1192 and medieval Europe's climate change can provide valuable insights into the Earth's past climate and how it has changed over time. This information can also help us better understand the potential impacts of future climate change and how societies can adapt and mitigate its effects.
