Climate Change and the Quiet Sun

The Global Warming Policy Foundation has just released a report "Climate Change and the Quiet Sun" (link).  This blog has previously used the attached graph  that illustrates the increased solar activity associated with both the Medieval Warm Period and the 20th century warming.  This figure also illustrates the reduced solar activity of the Maunder Minimum from 1645 to 1715 that was associated with the coldest temperatures of the Little Ice Age.

GWPF's new paper:
In 1700 the sun was just coming out of the longest period of sunspot inactivity known. It is called the Maunder Minimum. The Dalton Minimum followed closely on its heels. It lasted for two solar cycles in the early 1800s.

That was followed by the Modern Maximum that peaked the middle of last century. That maximum is among the highest periods of solar activity of the last 11,500 years going back to the last ice age.
Solar activity has been on the decline ever since.

Now solar physicists tell us to expect another minimum lasting more than one cycle.

The Maunder and Dalton minimums share something in common. Both are associated with cold periods in Earth’s climate history. The time of the Maunder Minimum is often referred to as the “Little Ice Age“.
