Chemistry World can't bring itself to mention Svensmark either.
Nor the Guardian.
Hooray for the Institute of Physics.
Henrik Svensmark of the National Space Institute in Copenhagen and colleagues hypothesize that the ions that are formed as (charged) cosmic rays pass through the atmosphere act as a kind of glue that makes it easier for molecules to stick together and form aerosols. This hypothesis has proved controversial because it suggests a role for solar variation, as well as human emissions of greenhouse gases, in climate change – the idea being that the stronger the Sun's magnetic field, the more cosmic rays are deflected away from the Earth, resulting in the formation of fewer clouds and so a warmer Earth, with a weaker solar magnetism having the opposite effect.
Reuters' coverage is disgraceful
* Study does not prove cosmic rays drive climate change
* Academics see cosmic ray effect as only very small
