How to keep cool or warm in your home by design, either in Summer or Winter, whilst reducing costs to you and the Earth..

David Archibald Religious cults promise a wonderful future if only people would believe. The promise the global warming cult made is that we would see the end of snow, no…

This long set of observations shows that the number of clouds grows increasingly following a peak in the solar cycle – where the Sun’s level of activity rhythmically rises and falls over an 11-year period.

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 hemisphere. The sun has been without a single observable...

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 trying to predict the timing and strength...

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 blast of radiation from the Sun that...

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)...

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 has created a cool visualization of the event. Video follows. …...

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 predicts that if the current lull in solar activity “endures...

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 pointing nearly strait at Earth...

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, NOAA.gov and...

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 been a dud...

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 period was Schatten and Tobiska’s 2003 paper...

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. A similar status quo in radio flux – little change from last month....

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 Leif Svalgaard – Click the pic to view...
