What was the weather like during the Maunder Minimum?
From 1650 to 1710, temperatures across much of the Northern Hemisphere plunged when the Sun entered a quiet phase now called the Maunder Minimum. During this period, very few sunspots appeared on the surface of the Sun, and the overall brightness of the Sun decreased slightly.
What is the Maunder Minimum How did it affect the earth?
Maunder minimum, unexplained period of drastically reduced sunspot activity that occurred between 1645 and 1715. Sunspot activity waxes and wanes with roughly an 11-year cycle. In 1894 the English astronomer Edward Walter Maunder pointed out that very few sunspots had been observed between 1645 and 1715.
What does the Maunder Minimum have to do with climate change?
Temperature decrease during Maunder minimum From 1645 to 1710, the temperatures across much of the Northern Hemisphere of the Earth plunged when the Sun entered a quiet phase now called the Maunder Minimum.
What does the word Maunder Minimum mean?
unusually low sunspot activity
[ môn′dər, män′- ] A period of unusually low sunspot activity lasting from approximately 1645 to 1715, as noted in records kept by contemporary observers.
How long did the Maunder Minimum last?
around 1645 to 1715
The Maunder Minimum, also known as the “prolonged sunspot minimum”, was a period around 1645 to 1715 during which sunspots became exceedingly rare. During a 28-year period (1672–1699) within the minimum, observations revealed fewer than 50 sunspots.
How much colder was the Little Ice Age?
During this epoch, often known as the Little Ice Age, temperatures dropped by as much as two degrees Celsius, or 3.6 degrees Fahrenheit. Compared with the extremes of snowball earth, that might not sound like much, but for people who lived through it the change was intensely dramatic.
How long does a Maunder Minimum last?
During a 28-year period (1672–1699) within the minimum, observations revealed fewer than 50 sunspots. This contrasts with the typical 40,000–50,000 sunspots seen in modern times over a similar timespan….Sunspot observations.
| Solar latitude | Rotation period (days) |
|---|---|
| 40° | 28.0 |
| 75° | 33.0 |
When was the last grand solar minimum?
Solar cycles still occur during these grand solar minimum periods but are at a lower intensity than usual….Solar minimum and maximum events with approximate dates.
| Event | Start | End |
|---|---|---|
| Maunder Minimum | 1645 | 1715 |
| Dalton Minimum | 1790 | 1820 |
| Modern Maximum | 1914 | 2008 |
Did the Maunder Minimum cause the Little Ice Age?
A previous period of low sunspot activity, the Maunder Minimum, lasted 70 years in the late 17th to early 18th century and coincided with part of the ‘Little Ice Age’ – a period of cooling affecting parts of the globe that lasted around 300 years.
Did England used to be colder?
In the Central England Temperature (CET) record extending back to 1659, only the winters of 1683–1684 and 1739–1740 were colder than 1962–1963.
What happens during a solar minimum?
Solar minimum is the regular period of least solar activity in the Sun’s 11-year solar cycle. During solar minimum, sunspot and solar flare activity diminishes, and often does not occur for days at a time.

When the next ice age is predicted?
Researchers used data on Earth’s orbit to find the historical warm interglacial period that looks most like the current one and from this have predicted that the next ice age would usually begin within 1,500 years.
