Science, the Sun, and El Niño

The science is settled? If anything, there is overwhelming evidence that science stands in stark contradiction to the simplistic global warming story peddled by politicians and the media. The basic driver and long-term determinant of climate change is the sun—plus many other factors among which human emissions are negligible—, with shorter term variations in temperatures generated by El Niño events—again with human emissions playing an insignificant role.
Introduction: Several recent studies of solar–geomagnetic effects on climate have been examined on both global as well as on regional scales.  The Sun’s long-term magnetic variability is the primary driver of climatic changes. The magnetic variability (mostly short-term components) is due to the disturbances in Earth’s magnetic fields caused by the solar activity, which is usually indicated by indices of geomagnetic activity. The Sun’s magnetic variability modulates the magnetic and particulate fluxes in the heliosphere. This determines the interplanetary conditions and imposes significant electromagnetic forces and effects upon planetary atmospheres. All these effects are due to the changing solar-magnetic fields which are relevant for planetary climates, including the climate of the Earth. The Sun–Earth relationship varies on different time scales of days to years bringing a drastic influence on the climatic patterns. The ultimate cause of solar variability, at time scales from decadal to cen tennial to millennial or even longer scales, has its origin in the solar dynamo mechanism. During the solar maxima, huge amounts of solar energy particles are released, thereby causing the geomagnetic disturbances. … The 11 years solar cycle acts an important driving force for variations in the space weather, ultimately giving rise to climatic changes. Therefore, it is very important to understand the origin of space climate by analyzing the different proxies of solar magnetic variability.”
The another most important climate variation is El Niño–Southern Oscillation (ENSO) events, which impact the global oceanic and atmospheric circulations which thereby produce droughts, floods and intense rainfall in certain regions. The strong coupling and interactions between the Tropical Ocean and atmosphere play a major role in the development of global climatic system. The El Niño events generally recur approximately every 3–5 years with large events spaced around 3–7 years apart. The El Niño–Southern Oscillation (ENSO) phenomena has shown huge impact on the Asian monsoon (Cole et al., 1993), Indian monsoon (Chowdary et al., 2006, 2014) as well as globally (Horel and Wallance, 1981; Barnett, 1989; Yasunari, 1985; Nicholson, 1997). In particular, the El Niño, solar, geomagnetic activities are the major affecting forces on the decadal and interdecadal temperature variability on global and regional scales in a direct/indirect way.”
