This post has been translated to German by Christian Freuer here. By Javier Vinós Fourteen years ago, a new climate myth was born. A grand solar minimum (GSM) was in the making that would not only reverse global warming but plunge the planet into a new Little Ice Age, surprising the warming alarmists and causingContinue reading “It is Time to Bury the Grand Solar Minimum Myth”

The Sun-Climate Effect: The Winter Gatekeeper Hypothesis (II). Solar activity unexplained/ignored effects on climate
by Javier Vinós & Andy May “The complicated pattern of sun-weather relationships undoubtedly needs much further clarification, but progress in this field will be hindered if the view prevails that such relationships should not be taken seriously simply because the mechanisms involved in explaining them are not yet identified.” Joe W. King (1975) For thoseContinue reading “The Sun-Climate Effect: The Winter Gatekeeper Hypothesis (II). Solar activity unexplained/ignored effects on climate“

The Sun-Climate Effect: The Winter Gatekeeper Hypothesis (I). The search for a solar signal
by Javier Vinós & Andy May “Probably no subfield of meteorology has had as much effort devoted to it as the effects of solar variability on weather and climate. And none has had as little to show for the research labor.” Helmut E. Landsberg (1982) For those that prefer it, Christian Freuer has translated thisContinue reading “The Sun-Climate Effect: The Winter Gatekeeper Hypothesis (I). The search for a solar signal”

Can we predict long-term solar variability?
By Andy May This post is a result of an online conversation with Dr. Leif Svalgaard, a research physicist at Stanford University. Leif knows a great deal about the Sun and solar variability and can explain it clearly. Our disagreement is over whether long-term solar variations could be large enough to affect Earth’s climate moreContinue reading “Can we predict long-term solar variability?”

IPCC Politics and Solar Variability
By Andy May This post is about an important new paper by Nicola Scafetta, Richard Willson, Jae Lee and Dong Wu (Scafetta, Willson and Lee, et al. 2019) on the ACRIM versus PMOD total solar irradiance (TSI) composite debate that has been raging for over 20 years. ACRIM stands for Active Cavity Radiometer Irradiance Monitor,Continue reading “IPCC Politics and Solar Variability”

It’s the gradient, stupid!
How does the Sun drive climate change? Guest Post by Javier The dispute between scholars that favor a periodical interpretation of climate changes, mostly based on astronomical causes, and those that prefer non-periodical Earth-based explanations has a long tradition that can be traced to the catastrophism-uniformitarianism dispute and how the theory of ice ages (nowContinue reading “It’s the gradient, stupid!”

How constant is the “solar constant?”
The IPCC lowered their estimate of the impact of solar variability on the Earth’s climate from the already low value of 0.12 W/m2 (Watts per square-meter) given in their fourth report (AR4), to a still lower value of 0.05 W/m2 in the 2013 fifth report (AR5), the new value is illustrated in Figure 1. TheseContinue reading “How constant is the “solar constant?””

Climate Change, due to Solar Variability or Greenhouse Gases? Part B.
By Andy May In a previous post, Part A here, we discussed the role of oceans, the Earth’s orbit, and human greenhouse gas emissions on climate change. In this post we discuss the impact of solar variability.
