The Sun-Climate Effect: The Winter Gatekeeper Hypothesis (Parts I & II)

The scientific consensus about an important sun-climate effect went from being against, prior to 1850, to being in favor between 1860s–1920s, negative from the 1920s–1960s, positive again in the 1960s–1970s, and then negative since the 1980s. It only demonstrates that scientific consensus has no place in science. Scientist’s opinions are not science. Only evidence constitutes science. Even though evidence can be dismissed or ignored, it remains, waiting for the time when it will be properly reappraised.

The fall of the sun-climate subfield during the early 1980s discouraged further research into how solar variability affects climate. The strengthening of the politically supported CO2 hypothesis of climate change turned the subfield into a scientific dead zone. Only a handful of researchers decided to pay the steep reputational and career price of pursuing this research interest.

Over the following five parts in this series of articles we will explain the recently proposed Winter Gatekeeper hypothesis of sun-climate effect (Vinós 2022). It involves some very complex climate phenomena, which explains why it escaped discovery for 220 years.
