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

Spencer’s posited 1-2% cloud cover variation found

In a nutshell, with a −1.6%per decade change in cloud cover during 1954–2005, it becomes a climate forcing. While China is not the world, it bears consideration. The Hockey Schtick reports: New paper finds significant, natural decrease in cloudiness over … Continue reading
