Sunspots and Norwegian Child Mortality

Guest Post by Willis Eschenbach In January there was a study published by The Royal Society entitled “Solar activity at birth predicted infant survival and women’s fertility in historical Norway”, available here. It claimed that in Norway in the 1700s and 1800s the solar activity at birth affected a child’s survival chances. As you might imagine, this…

The CERES Calculated Surface Datasets

Guest Post by Willis Eschenbach The CERES dataset is satellite data that is based on radiation measurements made from low earth orbit. The CERES data has two parts. The first part is observational data, measurements of downwelling and upwelling solar radiation and of upwelling longwave radiation. It is usually referred as the CERES “top-of-atmosphere” data.…

TAO And TAO Again

Guest Post by Willis Eschenbach Impelled by my restless curiosity, I’ve returned to the TAO buoy dataset to investigate a claim by Dr. Ramanathan of a “super-greenhouse” effect. The TAO buoys are a number of moored buoys located across the Pacific. The TAO data is available here. Figure 1. Locations of all of the sites…

Volcanoes and Sunspots

Guest Post by Willis Eschenbach I keep reading how sunspots are supposed to affect volcanoes. In the comments to my last post, Tides, Earthquakes, and Volcanoes, someone approvingly quoted a volcano researcher who had looked at eleven eruptions of a particular type and stated: …. Nine of the 11 events occurred during the solar inactive phase…

Tides, Earthquakes, and Volcanoes

Guest Post by Willis Eschenbach [Graphs updated to include error bars] Inspired by the paper by the charmingly-named Maya Tolstoy discussed here on WUWT, I decided to see if tidal forces affect the timing of earthquakes and volcanoes. Dr. Tolstoy’s hypothesis is that tidal forces affect the timing of the subterranean eruptions … but she has…

Something Fishy about Mercury

Guest Post by Willis Eschenbach There’s a new study out called Increase in mercury in Pacific yellowfin tuna by Paul E. Drevnick, Carl H. Lamborg, and Martin J. Horgan. It claims that: By compiling and re-analyzing published reports on yellowfin tuna (Thunnus albacares) caught near Hawaii (USA) over the past half century, the authors found…
