Looking at the English-language media, one might be led to think that the latest CERN experimental results show that trees alone dominate cloud formation, by supplying the necessary cloud seeding medium. Little reference is made to cosmic rays acting as the cloud formation modulator, initiating the cloud seeding process, as hypothesized by Henrik Svensmark. Lubos […]

Climate change on Mars – is it analogous to that on Earth? By Dr. Dietrich E. Koelle [Translated/edited by P Gosselin] Fig. 1: Structure of the Milky Way (Wikipedia, NASA/JPL-Caltech/R. Hurt) Drawing conclusions on the development of the Earth’s climate from climate change on Mars would be quite difficult because there is no concrete data from […]

Recently I posted a number of reports on the powerful correlation between solar activity cycles and historical climate change. Clearly the sun is a driver. The question that remains is what is the mechanism that drives climate. Recently there have been a number of papers showing Danish physicist Henrik Svensmark is on the right path […]

There’s been lots of disingenuous criticism from the CO2 end-of the world warmists and Armageddonists aimed at Fritz Vahrenholt’s and Sebastian Lüning’s new best selling skeptic book Die kalte Sonne. Much of it attacking Svensmark’s theory of solar amplification via cosmic rays. Again. none have really read the book, they simply repeat the same old […]

Only 8 days to go! A new paper published today in Atmospheric Chemistry and Physics suggests that the relationship proposed by Henrik Svensmark is supported. Svensmark proposes that changes in the sun’s magnetic field modulate the density of Galactic Cosmic Rays (GCRs) which in turn seed cloud formation on Earth, which changes the albedo/reflectivity to affect […]

I’ve gotten into a bit of a squabble at Georg Hoffmann’s blog concerning Henrik Svensmark’s cosmic ray cloud-seeding hypothesis. Hoffmann cites two recent papers that investigate Forbush decreases and their impacts on clouds, and thus climate. The two papers reach different conclusions. The first paper is by Calogovic et al. (Jürg Beers Gruppe) in GRL, which analyses […]

Sun, clouds and climate – a post from an EIKE reader Image: NASA (public domain) Posted by AR Göhring In a conversation with the EIKE editorial team, our reader Garik Müller noted that recent solar storms have promoted cloud formation – which would contradict the Svensmark-Shaviv effect and the Forbush effect. But the Earth’s atmosphere […]

Per a new study, million-year variations in cosmic rays (CR) modulating cloud cover, which, in turn, drives variations in incident solar radiation on short- and long-term timescales, is the dominant cause of million-year climate variations, explaining all 7 Ice Age epochs over the Phanerozoic. In contrast, declining CO2 and rising solar luminosity over the last […]

Solar Influence On Climate Scafetta, 2021 This result implies that the CMIP5 models are missing important climatic mechanisms responsible for a large millennial oscillation that has been found throughout the Holocene and has been linked to a millennial solar oscillation [2,4,17,72,90,105]. The argument can be, therefore, extended to other decadal, multidecadal, and secular solar oscillations […]

“Clouds may be the most important parameter controlling the radiation budget, and, hence the Earth climate.” – Sfîcă et al., 2021 It has become more and more common for scientists to attribute modern radiation budget (climate) changes to variations in cloud cover. This should not be surprising. It’s been pointed out (van Heerwaarden et al., […]

Connection between cosmic rays, clouds and radiation budget is reaffirmed…CO2 role thus has to be much smaller. There have been a flurry of recently published studies on radiative forcing and its variation due to cloud changes. The latest is a new study published in the journal Nature. Climate scientists Dr. Henrik Svensmark and colleagues have found […]

Scientists continue to affirm the critical role of clouds in modulating the Earth’s energy budget, and, hence, the climate. The total net forcing of the entirety of the CO2 influence on climate has been less than 2 W/m² since 1750 (Feldman et al., 2015). Image Source: Feldman et al., 2015 On a per-decade basis, a 22 […]
