Exploding Stars Influence Climate of Earth

Technical Rating: star
Dr. Svensmark of the Danish National Space Center shows that a recent experiment confirms that cosmic rays affect the Earth's cloud cover, thereby influencing our climate. The changing solar coronal magnetic field strongly affects the cosmic ray flux entering the Earth's atmosphere.


Technical Rating: star star
Dr. Svensmark shows how cosmic rays seed low clouds, which provides an amplification of the Sun's influence on climate change. He shows the Sun affects Earth's climate on all time scales.

The Persistent Role of the Sun

Technical Rating: star
Henrik Svensmark and Eigel Friis-Christensen, of the Danish National Space Center, reply to Mike Lockwood and Claus Frohlich, concerning the latter's paper that claims the Sun is no longer linked with climate change.

A Critique of the Lockwood/Frohlich paper - Royal Society Proceedings

Technical Rating: star
FoS has prepared this critique of the paper published in the Proceedings of The Royal Society, and presented on BBC. Taking into account of the time delay due to the heat capacity of the oceans, global temperatures are responding to the changing solar output as expected.

Solar Signature in Northern Temperature Since 1600

Technical Rating: star star
N. Scafetta of Duke University, Durham, NC and B.J. West of the US Army Research Office, NC studied the solar impact on 400 years of the Northern Hemisphere temperatures. The Phenomenological approach is used to determine the portion of the warming since 1900 is due to the Sun versus other factors, such as CO2 induced warming. The study compares the variations of Sun proxies to the temperature record and concludes that the Sun has contributed 50% to 69% of the recorded surface warming from 1900 to 2005 depending on the temperature reconstruction and satellite data used. The authors recognized that the surface temperature record is contaminated by the urban heat island effect but did not correct the record for the effect. FOS notes that if the temperature record were corrected for the urban warming effect, the study would show the Sun contributing at least 75% of the warming.
