Scientists: It’s The Sun
“The emerging causal effects from SS [solar activity] to GT [global temperatures], especially for recent decades, are overwhelmingly proved” – Huang et al., 2017
“Climate … follows SA [solar activity] fluctuations on multidecadal to centennial time scales” – Moreno et al., 2017
“The solar ‘activity’ increase is the chief driver of the global temperature increase since the LIA [Little Ice Age]” – Page, 2017
“A large proportion of climate variations can be explained by the mechanism of action of TSI [total solar irradiance] and cosmic rays (CRs) on the state of the lower atmosphere and other meteorological parameters” – Biktash, 2017
“The activity level of the Modern Maximum (1940–2000) is a relatively rare event, with the previous similarly high levels of solar activity observed 4 and 8 millennia ago” – Yndestad and Solheim, 2017
“The main driver of the large-scale character of the warm and cold episodes may be changes in the solar activity. Four warm periods – 1626–1637, 1800–1809, 1845– 1859, and 1986–2012 – have been identified to correspond to increased solar activity” – Tejedor et al., 2017
Solar Forcing As Significant Temperature/Climate Driver
Li et al., 2017 It has been widely suggested from both climate modeling and observation data that solar activity plays a key role in driving late Holocene climatic fluctuations by triggering global temperature variability and atmospheric dynamical circulation … The strengthened solar activity could be significantly amplified by the variations in ultraviolet radiation as well as clouds, resulting in the marked variability in global surface temperature. … … [O]verall solar-dominated long-term control.
Huang et al., 2017 (full) Various scientific studies have investigated the causal link between solar activity (SS) and the earth’s temperature (GT). [T]he corresponding CCM [Convergent Cross Mapping] results indicate increasing significance of causal effect from SS [solar activity] to GT [global temperature] since 1880 to recent years, which provide solid evidence that may contribute to explaining the escalating global tendency of warming up recent decades. … The connection between solar activity and global warming has been well established in the scientific literature. For example, see references [1–10]. … Among which, the SSA [Singular Spectrum Analysis] trend extraction is identified as the most reliable method for data preprocessing, while CCM [Convergent Cross Mapping] shows outstanding performance among all causality tests adopted. The emerging causal effects from SS [solar activity] to GT [global temperatures], especially for recent decades, are overwhelmingly proved, which reflects the better understanding of the tendency of global warming.
Blaauw, 2017 This paper demonstrates that global warming can be explained without recourse to the greenhouse theory. This explanation is based on a simple model of the Earth’s climate system consisting of three layers: the surface, a lower and an upper atmospheric layer. The distinction between the atmospheric layers rests on the assumption that the latent heat from the surface is set free in the lower atmospheric layer only. The varying solar irradiation constitutes the sole input driving the changes in the system’s energy transfers.
Wen et al., 2017 A warmer and wetter climate prevailed since ∼4800 a BP and was interrupted by a sharp cold reversal at approximately 3300 a BP that was likely caused by solar irradiance forcing, which resulted in a global cold climatic change and glacier advance.
Xiao et al., 2017 Solar wind and electric-microphysical process is the key mechanism that affects climate … [T]he wintertime Iceland Low in the North Atlantic was very sensitive to solar wind variations and played an important role in the process of solar wind and electric-microphysical effects on climate. Tinsley and Zhou (2015) improved the collision and parameterization scheme that varied with electric quantity in a cloud microphysics process and quantitatively evaluated the effects of high-energetic particle flux on cloud charge. This achievement not only supports the marked association of solar activity with weather and climate change on various time scales, but also but also avails the quantitative accession of solar impacts on climate.
