John Birks – At the frontiers of palaeoecology

This week, the University of Bergen is holding a seminar in honour of John Birks and his academic career so far. He retired earlier this year, at least from teaching and administration duties. Several well known palaeo/ecologists who have either … Continue reading

The Sun’s apparent orbit is not an icosikaitetragon

The Sun appears to go around the Earth. Round that is, like a circle, not jumping every hour from one side to the next of a 24-sided polygon. Despite this, it is convenient to represent the Sun’s position in climate models as if … Continue reading

I’ve been searching for robust evidence of the influence of solar variability on Earth’s climate. Zhao & Wang (2014) promise it in a paper I found at the Club du Soleil. They are looking for a correlation between annual sunspot number and the … Continue reading

Happy Perihelion

When better than perihelion to think about orbital forcing? I’ve wanted extract some insolation data for the late Quaternary to compare with some proxies as part of a rebuttal of some nonsense written elsewhere. Two insolation datasets are available from the Paleoclimatology … Continue reading

Tibetan tree-rings and the sun

Via Maarten Blaauw’s Club du Soleil, I’ve found another paper reporting evidence of solar variability in tree-rings from Tibet. The evidence in the first was dubious, is Duan and Zhang (2014) any better? Readers familiar with this series critically evaluating … Continue reading
