Svensmark’s Cosmic Theory and Cloud Cover Depictions in Little Ice Age Art.

Guest essay by Dr. Tim Ball Correlation between sunspot numbers and global temperature was known for decades, but with no proven mechanism it was correctly set aside. That changed when Henrik Svensmark proposed his Cosmic Rays hypothesis. Figures 1 and 2 … Continue reading

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

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
