... the Laurentide ice sheet. Possibly, the late Holocene cold events after c . 4 ka BP are influenced by the covarying influence of major tropical volcanic eruptions and Grand Solar Minima. Twenty-three temperature and 17 humidity–precipitation time series were collected from open access sources...

... to local cooling in the Northern Hemisphere, especially 8200 years ago in an event that has a global signature. Late Holocene cold events of the past 3000 years seem largely to represent the superimposition upon the orbital decline in insolation of large tropical volcanic eruptions and Grand Solar Minima...

... Lake, Alaska, indicates that solar activity may have directly contributed to varve deposition. A varve thickness sequence is compared to sunspot observations from 1610–1995 CE. Maunder and Dalton minima are clearly expressed in a varve power spectrogram; varve signal amplification beginning ca. 1950s...

... interglacials. Days in the year At the other end of the astronomical spectrum, Whyte (1977), following Creer (1975), argued that minima in days/month or solar days/year occur at c. 445 Ma (late Ordovician) and 235 Ma (end-Permian) and possibly today, and so coincide with, or are pre- ceded by, ice-ages, whereas...

... the fact that seasonal change in temperature over much of the Earth's surface is sinusoidal. This pattern arises because, particularly at non-equatorial latitudes such as that represented by this mollusc (∼ 32° N), variation in incident solar radiation is also largely sinusoidal. An abundance of data...

... activity is also subject to variations on longer timescales. A prominent minimum of solar activity, during which almost no aurora and sunspots were observed, has been reported for the years 1645–1715 A.D., the so-called Maunder minimum ( Eddy 1976 ). Other minima have been identified from 14 C and 10...
