The Chilling Stars - I think that is the explanation that bothers warmers the most.
That is because the astrophysicists and the geologists they are working with have actually backed up the theory with measurable evidence and created experiments to test key parts of the theory (cosmic ray cloud seeding) that have worked. Warmers hate real science, not enough doom and gloom to take control of an industrial base if it comes down to the Earth being protected by the Sun from space radiation coming from the Milky Way. Heck, how can you regulate cow farts and SUVs if it is a cosmic problem and not man made?
