DR. CHREE in his reply (NATURE, September 8, p. 361) to my communication on solar activity and atmospheric electricity (NATURE, August 11, p. 203) first makes reference to the status of the question as to the effect of sun-spot activity on the secular change of the earth's magnetism....

The paper demonstrates the close relationships between the polar cap magnetic activity, which is characterized by PC index [Troshichev et al., 1988; Troshichev et al., 2006] and some at-mospheric phenomena typical of the winter Antarctica, such as enhancement of cloudiness, sudden warmings of...
specialized literature. For an introduction see e.g.Parker (1963),Sandström (1965),Dorman (1974),Longair (1992). More specific information can be found in proceedings of topical conferences, see e.g.Kunow (1992),Moraal (1993). However, some selected heliospheric phenomena are summarized in...
During the PETM recovery phase, increased wildfire activity transformed “short-term carbon sinks” of the biological-atmospheric carbon cycle into “long-term carbon sinks” through the burial of BC. This process of carbon sink conversion may have acted as a negative feedback mechanism, ...
atmospheric, hydrospheric, and, possibly, some aspects of geospheric phenomena are, or have been, powered by energy issuing from the sun – either now or in the past, the long-term behavior of such phenomena is ultimately quot;connectedquot; to long-term changes occurring in the sun itself...
For instance, solar-surface magnetic variability, eruption phenomena, coronal activity, radiation of the sun as a star or even interplanetary transients and geomagnetic disturbances can be related to the concept of solar activity. A variety of indices quantifying solar activity have been proposed in ...
