We see maximum cloudiness at solar maximum. Just the opposite of the Svensmark hypothesis

The Sun in June 2023
When the PDO finally turns negative it will hyper-accelerate the solar-driven cooling evident from 2016.
Secrets of Sunspots and Solar Magnetic Fields Investigated in NASA Supercomputing Simulations
New results based on simulations out of NASA’s Advanced Supercomputing facility at NASA’s Ames Research Center in California’s Silicon Valley are painting a more complete picture of one of the…
New sunspot catalogue to improve space weather predictions
Monitoring sunspots is therefore crucial for predicting dangerous space weather events and their effects on air travelers, astronauts, and the equipment and infrastructure — both on Earth, in orbit, and…
Scientists use AI to predict sunspot cycles
For the first time, scientists have used artificial intelligence not only to predict sunspots but also to correct the incomplete record of past sunspot activity.
A new look at sunspots
NASA’s extensive fleet of spacecraft allows scientists to study the Sun extremely close-up – one of the agency’s spacecraft is even on its way to fly through the Sun’s outer…
A New Cold Record set at International Falls: Should we be surprised?
News has come from the Duluth office of the National Weather Service that both International Falls & Hibbing broke their records for low temperatures on the morning of September 17.…
The Carrington Event: September 1st, 1859
In fact, it was this same time of year back in 1859 when a super solar storm – now known as the “Carrington Event” – took place during another weak…
Plasma flow near sun’s surface explains sunspots, other solar phenomena
University of Washington For 400 years people have tracked sunspots, the dark patches that appear for weeks at a time on the sun’s surface. They have observed but been unable…
Sharpening a Cyclical Shovel
Guest Post by Willis Eschenbach There are a number of lovely folks in this world who know how to use a shovel, but who have never sharpened a shovel. I’m…
CEEMD and Sunspots
Guest Post by Willis Eschenbach I’ve been investigating the use of the “complete ensemble empirical mode decomposition” (CEEMD) analysis method, which I discussed in a previous post entitled Noise-Assisted Data…
Noise Assisted Data Analysis
Guest Post by Willis Eschenbach Once again, Dr. Curry’s “Week in Review-Science and Technology” doesn’t disappoint. I find the following: Evidence of a decadal solar signal in the Amazon River:…
Is The Climate Chaotic?
Guest Post by Willis Eschenbach After I’d published my previous post on the Hurst Exponent entitled A Way To Calculate Effective N, I got an email from Dan Hughes which…
The Missing ~ 11-Year Signal
Guest Post by Willis Eschenbach Dr. Nir Shaviv and others strongly believe that there is an ~ 11-year solar signal visible in the sea level height data. I don’t think…
My Thanks, Apologies, and Reply to Dr. Nir Shaviv
Guest Post by Willis Eschenbach Dr. Nir Shaviv has kindly replied in the comments to my previous post. There, he says: Nir Shaviv August 15, 2015 at 2:51 pm There…
The New Sunspot Data … and Satellite Sea Levels
Guest Post by Willis Eschenbach [UPDATE: Upon reading Dr. Shaviv’s reply to this post, I have withdrawn any mention of “deceptive” from this post. This term was over the top, as…
Sunspots and Norwegian Child Mortality
Guest Post by Willis Eschenbach In January there was a study published by The Royal Society entitled “Solar activity at birth predicted infant survival and women’s fertility in historical Norway”, available…
Splicing Clouds
Guest Post by Willis Eschenbach So once again, I have donned my Don Quixote armor and continued my quest for a ~11-year sunspot-related solar signal in some surface weather dataset.…
Maunder and Dalton Sunspot Minima
Guest Post by Willis Eschenbach In a recent interchange over at Joanne Nova’s always interesting blog, I’d said that the slow changes in the sun have little effect on temperature.…
Sunspots and Sea Surface Temperature
Guest Post by Willis Eschenbach I thought I was done with sunspots … but as the well-known climate scientist Michael Corleone once remarked, “Just when I thought I was out…
Well, Color Me Gobsmacked!
Guest Post by Willis Eschenbach I’ve developed a curious kind of algorithm that I’ve humorously called “slow Fourier analysis”, but which might be better described as a method for direct…
The Effect of Gleissberg's "Secular Smoothing"
Guest Post by Willis Eschenbach ABSTRACT: Slow Fourier Transform (SFT) periodograms reveal the strength of the cycles in the full sunspot dataset (n=314), in the sunspot cycle maxima data alone…
The Tip of the Gleissberg
Guest Post by Willis Eschenbach A look at Gleissberg’s famous solar cycle reveals that it is constructed from some dubious signal analysis methods. This purported 80-year “Gleissberg cycle” in the…
Cosmic Rays, Sunspots, and Beryllium
Guest Post by Willis Eschenbach In investigations of the past history of cosmic rays, the deposition rates (flux rates) of the beryllium isotope 10Be are often used as a proxy…
