Maunder minimum

n.
A period of unusually low sunspot activity lasting from approximately 1645 to 1715, corresponding roughly to the middle and coldest portion of the Little Ice Age.

[After Edward Walter Maunder (1851-1928), British astronomer who identified it in records of sunspot activity from the time.]

Professor Zharkova's work on sun spots and the Maunder minimum may well explain why people were able to skate on the Thames in the 1650s but, as she says herself, the "research cannot be used as proof that there will be a mini ice age this time around, not least because of global warming".
Professor Zharkova's work on sun spots and the Maunder minimum may well explain why people were able to skate on the Thames in the 1650s, but as she has says herself the 'research cannot be used as proof that there will be a mini ice age this time around, not least because of global warming' and goes on to warn 'any downward impact on global warming will last only until the Sun's two magnetic waves become active again in the 2050s.
But some reconstructions indicate that the Maunder Minimum followed several periods of decreasing activity.
The stellar dynamo is caused by the interaction between the a star's magnetic fields, its convection and its rotation, but given what we know about the solar cycle - such as the Maunder Minimum in the 17th century, when solar spots were almost nonexistent for about 50 years - our knowledge is clearly far from complete.
One example is the so-called Maunder Minimum, a period in the 17th century, where spots almost disappeared from the surface of the Sun for a period of over 50 years.
During the 70-year period that followed, known as the Maunder Minimum, sunspots appeared only rarely on the surface of the Sun--though our star did continue its 11-year cycle of activity during this time.
I found this very interesting to work scientifically, internationally in a European project, and my part was to work on the Maunder Minimum climate and to reconstruct climate during the period around 1700.
Because Earth receives less solar radiation during lulls in sunspot activity, the Northern Hemisphere was cooler during the Maunder Minimum than in the time periods before or after.
The researchers estimate that hurricane frequency was one-fourth the long-term average in 1645 to 1715--a period known as the Maunder Minimum, when the sun dimmed to its lowest recorded brightness.
Inspiriert durch die Arbeiten John Eddys zum Maunder Minimum (1), hat Parker auch den Klimawandel in die Diskussion zuruckgeholt.
London, Jan 19 ( ANI ): Scientists have warned that the recent lack of activity in sun could lead to a new mini ice age, just like 17th century's Maunder Minimum, in European countries.
There is a precedent; sunspots disappeared almost completely from 1645 to 1715, an event called the Maunder Minimum.
