Sun spotless for 33 days straight – airline travelers getting dosed with up to 70 times more radiation [than at sea level]

Are we in a solar grand minimum? We’ve seen this before, but now predictions are for an extremely weak solar cycle ahead. Today is the summer solstice in the northern…

Scientists tackle a burning question: When will our quiet sun turn violent?

From Science Mag A violent, active sun, as seen in ultraviolet light in October 2014—near solar maximum in its 11-year solar cycle. As the sun approaches solar minimum, scientists are…

Monster solar storm that hit Earth discovered in the past

Something this big today would surely fry electrical grids, GPS, and communications. It may be bigger than the Carrington Solar event of 1859. Scientists have found evidence of a huge…

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…

MSM finally gets that the sun's magnetic field has flipped

While we’ve known about this for quite some time at WUWT, going back to August 2013, the story is now starting to make the rounds in the MSM. And, NASA…

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…

Sunspot group AR1890 takes direct aim at earth

May produce a dangerous X-class flare that could directly impact Earth Steve Davidson writes: Right now, today, one of the largest sunspot groups of Cycle 24 – AR1890 – is…

September doldrums – solar slump continues

While many science related government agencies are shut down (NASA GISS is deemed ‘non-essential’ for example) some remain open due to statements like this: Due to the Federal Government shutdown,…

Like 'the pause' in surface temperatures, 'the slump' in solar activity continues

The NOAA Space Weather Prediction Center has updated their monthly graph set and it is becoming even more clear that we are past solar max, and that solar max has…

The Climate-Grain Production Relationship Quantified

Guest essay by David Archibald There is now consensus that the Sun has now entered a quiet period. The first paper from the solar physics community predicting the current quiet…

Solar cycle 24 continues the slump

Sunspot count is virtually unchanged from last month : It seems possible that we’ve seen the double peak, and it will be downhill after this.

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…

Newsbytes: Sun's Bizarre Activity May Trigger Another Little Ice Age (Or Not)

From the GWPF and Dr. Benny Peiser “Weakest Solar Cycle In Almost 200 Years” The sun is acting bizarrely and scientists have no idea why. Solar activity is in gradual…

The solar cycle is still slumping

It is looking more and more like a double sunspot peak for solar cycle 24. Sunspot count is down again:  A similar drop occurred in radio flux.

CET cooling in line with solar model prediction

Yesterday, WUWT carried the headline: Coldest Spring In England Since 1891.  This essay offers what could be an explanation for it. Judge for yourself. – Anthony Guest essay by David…

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.…

Sunspot Cycle and the Global Temperature Change Anomaly

UPDATE: The author writes: Thank you for posting my story on Sunspots and The Global Temperature Anomaly. I was pleasantly surprised when I saw it and the amount of constructive…

February solar data shows the Sun to still be slumping – but NASA says 'twin peaks' may happen

The data from SWPC is in, and it is lethargic at best. Sunspot numbers took a hit, down to about 42,  a delta of ~50 lower compared to the red…

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…

Update on Solar Cycle 24 – Hathaway's latest predictions show smallest sunspot cycle since 1906

The sun is currently showing two significant spots, though activity is generally quiet. Current SSN is 30, and Sunspot AR1667 (on the left) is in decay, and it is no…

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…

Neutrons and the 1970s cooling period

Note: the original title Solar Neutrons and the 1970s cooling period was unintentionally misleading as Dr. Svalgaard points out in comments: What produces Solar Neutrons? the title of the post…

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…

The sun – still slumping

The latest solar cycle update graphs have been released by the NOAA SWPC today, and the anemic cycle 24 continues: The current count isn’t keeping up with the prediction line…
