Guest post by John Tillman Disulfur Dioxide, the Solar Cycle and Cosmic Rays in the Venusian Atmosphere In 1928, Yerkes Observatory astronomer and physicist Frank Ross published a journal paper, “Photographs of Venus”. It reported finding in the Venusian atmosphere a strong absorption between 320 and 400 nm, ie in the near-UV, just overlapping light…
Revealing the impact of cosmic rays on the Earth’s climate Kobe University New evidence suggests that high-energy particles from space known as galactic cosmic rays affect the Earth’s climate by increasing cloud cover, causing an “umbrella effect”. When galactic cosmic rays increased during the Earth’s last geomagnetic reversal transition 780,000 years ago, the umbrella effect…
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 by the solar wind M Voiculescu et al 2013 Environ. Res. Lett. 8 045032 doi:10.1088/1748-9326/8/4/045032 Abstract In this letter we investigate possible relationships between the cloud…
Note: I’m going to leave this as a sticky “top post” for a day or so. new stories appear below. Nigel Calder asks us to republish this post for maximum exposure. He writes: Today the Royal Astronomical Society in London publishes (online) Henrik Svensmark’s latest paper entitled “Evidence of nearby supernovae affecting life on Earth”.…
Reblogged from Calder’s Updates In the climax to the Danes’ experiments, cloud seeds flout the theories Near to the end of the story that starts with stars exploding in the Galaxy and ends with extra clouds gathering, a small but important paragraph was missing till now. From experiments in Copenhagen reported in 2006 and reconfirmed…
This new paper shows what appears to be a link between Forbush descreases and terrestrial temperature change shortly afterwards. It is a short time scale demonstration of what Svensmark is positing happens on a longer climate appropriate time scale as the solar magnetic field changes with long periods. I’ve covered the topic of Forbush decreases…
Guest post by Alec Rawls Andrew Orlowski at the UK Register has an anecdotal account of Downing College’s skeptics-vs-believers mash-up. Ace of Spades pulled the juiciest bit: In short, the day lined up Phil Jones, oceanographer Andrew Watson, and physicist Mike Lockwood, the latter to argue that the sun couldn’t possibly have caused recent warming.…
Above: (artist conception) Astronomers have discovered the biggest black hole orbiting a star 1.8 million light-years from Earth in the constellation Cassiopeia, with a record-setting mass of 24 to 33 times that of our Sun. Henrik Svensmark is probably pleased to know where there source of cosmic rays is. Knowing that may help him hone his theory…
“All Quiet Alert” – That sounds like an oxymoron, and maybe it is, but the sun is extremely quiet right now, so much in fact that the Solar Influences Data Center in Belgium has issued an “All quiet alert” on October 5th. Since then, the sunspot number has remained at zero. Here is what the…
