Solar Periodicity

Guest Post by Willis Eschenbach I was pointed to a 2010 post by Dr. Roy Spencer over at his always interesting blog. In it, he says that he can show a relationship between total solar irradiance (TSI) and the HadCRUT3 global … Continue reading

Historical and present Total Solar Irradiance has been tinkered with again

One of the big problems of climate science is uncertainty. Some things that always seem to be in flux are historical datasets, partly because, well, they have so much inherent uncertainty built in. Such is the case of the Historical … Continue reading

January solar cycle 24 numbers, a new high for one, continued slumps for others

The NOAA Space Weather Prediction Center released their January 2014 solar data, and it has one small surprise, the 10.7 radio flux is the highest ever in cycle 24, the other metrics, not so much. SSN has been about where … Continue reading

New study claims low solar activity caused “the pause” in global temperature – but AGW will return!

This is on a tip from Dr. Leif Svalgaard, WUWT’s resident solar expert. It was just published in the journal Atmospheric and Climate Sciences, and is open access. I found this study’s conclusion a bit amusing, because there are numerous … Continue reading

The Solar storm has arrived – initial impact weaker than expected

From NASA: Spaceweather: As expected, a CME hit Earth’s magnetic field on Jan. 9th (around 20:00 UTC or 3 p.m. EST). Although the initial impact was weaker than expected, geomagnetic storms could still develop as Earth passes through the CME’s … Continue reading

Upwelling Solar, Upwelling Longwave

Guest Post by Willis Eschenbach The CERES dataset contains three main parts—downwelling solar radiation, upwelling solar radiation, and upwelling longwave radiation. With the exception of leap-year variations, the solar dataset does not change from year to year over a few … Continue reading

X class solar flare ejection may hit Earth with solar storm

From the WUWT Solar Reference page, an X 1.2 event has occurred: From NASA Spaceweather: Giant sunspot AR1944 erupted on Jan 7th at approximately 1832 UT, producing a powerful X1-class solar flare. First-look coronagraph images from the STEREO-Ahead spacecraft appear … Continue reading

On The Stability and Symmetry Of The Climate System

Guest Post by Willis Eschenbach The CERES data has its problems, because the three datasets (incoming solar, outgoing longwave, and reflected shortwave) don’t add up to anything near zero. So the keepers of the keys adjusted them to an artificial … Continue reading

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

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 causes for climate change aka global warming, Gavin Schmidt said: … Continue reading
