Solar Cycle Mystery Solved ?
Guest essay by David Archibald In the time before the current period of faith-based science, much good work was done on the role of the Sun in controlling climate. One…
Solar variability and the Earth's climate
Guest essay by Andy May According to Javier and the IPCC, total solar radiation output varies little, less than 0.1%. This is only 0.7 to 1.4 Watts/m2 compared to an…
A TSI-Driven (solar) Climate Model
Guest essay by Jeff Patterson Temperature versus CO2 Greenhouse gas theory predicts a linear relationship between the logarithm of CO2 atmospheric concentration and the resultant temperature anomaly. Figure 1 is…
UK MET Office: Fastest decline in solar activity since the last ice age
h/t Benny Peiser – the UK MET office has published a study which suggests solar activity is currently plummeting, the fastest rate of decline in 9300 years. The study…
Solar Cycle Update
Guest essay by David Archibald Two useful things we would like to know are the length of Solar Cycle 24 and the amplitude of Solar Cycle 25. Figure 1 below…
Paper: Influence of solar cycles on climate change during the Maunder Minimum
Both observational and proxy records of climate change often show quasi periodic variations similar to solar activity cycles over a wide range of time scales. However, the detailed mechanism and…
Recent paper finds 1950-2009 Solar Grand Maximum was a 'rare or even unique event' in 3,000 years
Sun said to be “bi-modal” While many, including the IPCC, suggest the modern Grand Maximum of solar activity from 1950-2009 has nothing to do with the 0.4C global warming measured…
Gavin was for solar forcing of climate before he was against it
Readers may recall when Dr. Gavin Schmidt appeared on a television program with Dr. Roy Spencer, but by Gavin’s cowardly choice, not at the same time. After listing the known…
Study predicts the sun is headed for a Dalton-like solar minimum around 2050
Method uses the Ap geomagnetic index, which has been in a slump since October 2005: The Hockey Schtick tips us to a paper published today in Advances in Space Research…
BBC – Real risk of a Maunder minimum 'Little Ice Age'
From BBC’s Paul Hudson It’s known by climatologists as the ‘Little Ice Age’, a period in the 1600s when harsh winters across the UK and Europe were often severe. The…
A rebuttal to Steven Sherwood and the solar forcing pundits of the IPCC AR5 draft leak
Teaming up with Jo Nova to answer The Team down under: “Professor Sherwood is inverting the scientific method” Guest post by Alec Rawls My leak of the draft IPCC report…
Solar Activity – Past, Present, Future
Essay/paper by Dr. Leif Svalgaard Abstract As our civilization depends increasingly on space-borne assets and on a delicate and vulnerable earth-bound infrastructure, solar activity and its potential impact becomes of…
Paper demonstrates solar activity was at a grand maximum in the late 20th century
Solar activity measured by isotope proxies revealed the end of 20th century was the highest activity in 1200 years A 2010 paper (that I somehow missed) was recently highlighted by…
Solar grand minima linked to cooling period in Europe
This is interesting. A quick cooling in Europe together with an increase in humidity and particularly in windiness was found to coincide with a long-term reduction in solar activity 2800…
Another solar study: this one suggests no significant solar influence
On Saturday I posted about this study from Pierre Gosselin at No Tricks Zone: New Study Shows A Clear Millennial Solar Impact Throughout Holocene Now we have another that suggests…
Omitted variable fraud: vast evidence for solar climate driver rates one oblique sentence in AR5
Guest post by Alec Rawls “Expert review” of the First Order Draft of AR5 closed on the 10th. Here is the first paragraph of my submitted critique: My training is…
New paper suggests sun may be headed for a Maunder minimum
Just published in GRL, a new paper by Lockwood et al that suggests the sun may be headed for a Maunder type minimum.: The persistence of solar activity indicators and…
Study: solar activity lull increases chances of cold UK winters
From the Institute of Physics More than 1 in 10 chance of colder UK winters As the Sun enters a period of low solar activity over the next 50 years,…
Watched solar CME's never boil?
I covered the recent uptick in solar activity earlier this month here and here last month. Now NASA offers this summary of the events, saying Cycle 24 is finally “on”.…
That solar sinking feeling
When I last wrote about the solar activity situation, things were (as Jack Horkheimer used to say) “looking up”. Now, well, the news is a downer. From the Space Weather…
Dalton Minimum Repeat goes mainstream
David Archibald writes in an email to WUWT: The AGU Fall meeting has a session entitled “Aspects and consequences of an unusually deep and long solar minimum”. Two hours of…
