Solar activity has a cyclic nature with the≈ 11-year Schwabe cycle dominating its variability
on the interannual timescale. However, solar cycles are significantly modulated in length …

Presented here is a review of present knowledge of the long-term behavior of solar activity
on a multi-millennial timescale, as reconstructed using the indirect proxy method. The …

Aims. The 11-year solar cycle (Schwabe cycle) is the dominant pattern of solar magnetic
activity reflecting the oscillatory dynamo mechanism in the Sun's convection zone. Solar …

Aims. Cosmogenic isotopes provide the only quantitative proxy for analyzing the long-term
solar variability over a centennial timescale. While essential progress has been achieved in …

Wide-field high-precision photometric surveys such as Kepler have produced reams of data
suitable for investigating stellar magnetic activity of cooler stars. Starspot activity produces …

New consistent and precise computations of the production of five cosmogenic
radioisotopes, 7Be, 10Be, 14C, 22Na, and 36Cl, in the Earth's atmosphere by cosmic rays …

Aims. The solar activity in the past millennia can only be reconstructed from cosmogenic
radionuclide proxy records in terrestrial archives. However, because of the diversity of the …

As we are heading toward the next solar cycle, presumably with a relatively small amplitude,
it is of significant interest to reconstruct and describe the past secular minima on the basis of …

In addition to the regular Schwabe cycles of approximately 11 y,“prolonged solar activity
minima” have been identified through the direct observation of sunspots and aurorae, as …

This book is an unorthodox ground-breaking scientific study on natural climate change and
its contribution to ongoing multi-centennial global warming. The book critically reviews the …
