Cosmic Rays, Sunspots, and Beryllium

Guest Post by Willis Eschenbach In investigations of the past history of cosmic rays, the deposition rates (flux rates) of the beryllium isotope 10Be are often used as a proxy for the amount of cosmic rays. This is because 10Be … Continue reading

More support for Svensmark’s cosmic ray modulation of Earth’s climate hypothesis

There is a new paper in Environmental Research Letters that give additional support to  Henrik Svensmark’s cosmic ray hypothesis of climate change on Earth. The idea is basically this: the suns changing magnetic field has an influence on galactic cosmic … Continue reading

Svensmark’s cosmic ray theory of clouds and global warming looks to be confirmed

Note: Between flaccid climate sensitivity, ENSO driving “the pause”, and now this, it looks like the upcoming IPCC AR5 report will be obsolete the day it is released. From a Technical University of Denmark press release comes what looks to … Continue reading

Study says global warming caused by CFCs interacting with cosmic rays, not carbon dioxide

From the University of Waterloo, an extraordinary claim. While plausible, due to the fact that CFC’s have very high GWP numbers, their atmospheric concentrations compared to CO2 are quite low, and the radiative forcings they add are small by comparison … Continue reading

Another amplification mechanism discovered by which the Sun affects Earth’s climate

From The Hockey Schtick A paper published Tuesday in the Journal of Climate finds tiny variations in solar activity over 11-year solar cycles have greatly amplified effects upon climate via changes in the Arctic Oscillation, North Pacific sea surface temperatures … Continue reading

Another solar to climate amplification mechanism found?

From the Hockey Schtick: Paper finds another amplification mechanism by which the Sun controls climate (video follows) A lecture by professor Hiroko Miyahara of the University of Tokyo provides additional support to the Svensmark theory of cosmoclimatology, finding that both … Continue reading

Commitment studies belie “consensus” claim that a persistent high level of temperature forcing cannot cause continued warming

Guest post by Alec Rawls They say it all the time: even if there were some substantial mechanism of enhanced solar forcing it couldn’t be responsible for late 20th century warming because solar activity was roughly constant from 1950 to … Continue reading

Dana Nuccitelli’s holiday trick for sobering up quick: put a little less rum in your egg nog

Guest post by Alec Rawls When he argues that a reduction in forcing will cause cooling Dana Nuccitelli is not actually talking about drinking. He is talking about the solar forcing of global temperature, but the drinking analogy is a handy … Continue reading

Haigh Anxiety: a psycho-comedy of errors

Guest post by Alec Rawls In an interview with NewScientist magazine, Imperial College professor of atmospheric physics Joanna Haigh scoffs at the idea that late 20th century warming could have been caused by the sun: Haigh points out that the … Continue reading

Claim: Five climate-forcing mechanisms govern 20,000 years of climate change

FOREWORD: I don’t agree with many of the claims made in this paper, particularly the retrograde tri-synodic Jupiter/Saturn cycle claims. This is not a peer reviewed paper. That said, I’m willing to allow discussion of it, so be skeptical of these … Continue reading

Some confirmation of Spencer’s cloud hypothesis – it is getting less cloudy and warmer at the same time

A new paper just published in the Journal of Climate finds that global cloudiness has decreased over the past 39 years from between 0.9 to 2.8% by continent as shown in the figure below: The period of the study is … Continue reading
