The sun today is cue-ball blank, a perfect unmarred sphere: The sun has just passed an entire calendar month with no sunspots. The last time this happened, in August 2008,…

Study: A Solar Signature in Many Climate Indices
Abstract Jean‐Louis Le MouëlFernand LopesVincent Courtillot We first apply singular spectrum analysis (SSA) to the international sunspot number (ISSN; 1849‐2015) and the count of polar faculae (PF; 1906‐2006). The SSA…
More support for Svensmark's cosmic ray modulation of Earth's climate hypothesis
There is a new paper in Environmental Research Letters that give additional support to Henrik Svensmark’s cosmic ray hypothesis of climate change on Earth. The idea is basically this: the…
New paper: Clouds blown by the solar wind
This paper suggests a terrestrial impact on cloud cover from the interplanetary electric field (IEF) via the global electric circuit. A primer video on the GEC is below. Clouds blown…
Claim: Solar, AMO, & PDO cycles combined reproduce the global climate of the past
Guest essay by H. Luedecke and C.O.Weiss We reported recently about our publication [1] which shows that during the last centuries all climate changes were caused by periodic ( i.e.…
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…
New paper says 'No evidence of planetary influence on solar activity'
“Barycentric” influence of the planets on the sun is just statistically insignificant, and a previous paper that claims to find a signal in isotopic records is proven to be nothing…
The sun is about to have a flipping magnetic field reversal
We’ve been watching the progress on the WUWT solar reference page in this plot from Dr. Leif Svalgaard: Solar Polar Fields – Mt. Wilson and Wilcox Combined -1966 to Present…
Solar cycle update – sun's magnetic activity still in a slump
Despite some small upticks on sunspot and 10.7cm radio activity, the magentic activity of the sun is still bumping along the bottom. A slight uptick was seen in sunspot count.…
Russian Scientists say period of global cooling ahead due to changes in the sun
From Radio Voice of Russia: Russia’s Pulkovo Observatory: “we could be in for a cooling period that lasts 200-250 years” Scientists at Russia’s famous Pulkovo Observatory are convinced that the…
Current solar cycle data seems to be past the peak
The NOAA Space Weather Prediction Center has updated their monthly graph set and it appears as if the slow downside from what looks like the solar max for cycle 24.…
A Comparison Of The Earth's Climate Sensitivity To Changes In The Nature Of The Initial Forcing
Guest post by Bob Irvine ABSTRACT The Earth’s feedback response to warming is independent of the nature of the forcing that caused that warming. The question I intend to examine…
How long to the 24/25 solar minimum?
Guest post by David Archibald Climate has real world consequences, and those operating in fields that will be affected by changing climate bring a different perspective to the problem of…
It's the Sun stupid – The minor significance of CO2
Guest post by Dr. Norman Page 1 The IPCC’s Core Problem The IPCC – Al Gore based Anthropogenic Global Warming scare has driven global Governments’ Climate and Energy Policies since the turn…
UV shift in the leaked IPCC report: more inversion of the scientific method
Guest post by Alec Rawls A Fox News story on the leaked draft of AR5 got big attention through the Drudge Report the other week. Fox reporter Maxim Lott begins…
Commitment studies belie "consensus" claim that a persistent high level of temperature forcing cannot cause continued warming
Guest post by Alec Rawls They say it all the time: even if there were some substantial mechanism of enhanced solar forcing it couldn’t be responsible for late 20th century…
NASA on the sun: '…tiny variations can have a significant effect on terrestrial climate."
Researchers have considered the possibility that the sun plays a role in global warming. From NASA GSFC: Solar Variability and Terrestrial Climate In the galactic scheme of things, the Sun…
The potential impact of volcanic overprinting of the Eddy Minimum
Guest post by David Archibald There were five named solar minima in the last millennium – the Oort, Wolf, Spörer, Maunder and Dalton minima. At least the last four were…
New paper demonstrates that climate responds to short and long-term changes in solar activity
(Via the Hockey Schtick) A new peer reviewed paper published in The Holocene finds a significant link between solar activity and climate over the past 1000 years. According to the…
Dana Nuccitelli's holiday trick for sobering up quick: put a little less rum in your egg nog
Guest post by Alec Rawls When he argues that a reduction in forcing will cause cooling Dana Nuccitelli is not actually talking about drinking. He is talking about the solar forcing…
IPCC Chapter 11 – Bankruptcy Protection
Guest post by David M. Hoffer IPCC reports AR1 through 4 were published in relative obscurity. ClimateGate and the emergence of the blogosphere as the primary forum for debate of…
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…
Isaac Held's 2-box model: another failed ocean-equilibration excuse for dismissing solar warming
Guest post by Alec Rawls Dr. Isaac Held, who models fluid dynamics at NOAA, dismisses a solar explanation for late 20th century warming by invoking a 2-box model of ocean…
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…
