New Study Finds Cosmic Rays-Climate Link

A breakthrough in the understanding of how cosmic rays from supernovae can influence Earth´s cloud cover and thereby climate is published today in the journal Nature Communications. Technical University of Denmark, 19 December 2017

We have finally found the last piece of the puzzle of why cosmic rays make clouds. It was to prove that ions do in fact produce cloud condensation nuclei that are needed for making clouds. After four years of intense work we have cracked the problem and found the underlying mechanism. Henrik Svensmark, GWPF Observatory, 19 December 2017

The impact of changes in solar activity on Earth’s climate was up to seven times greater than climate models suggested according to new research published today in Nature Communications. Researchers have claimed a breakthrough in understanding how cosmic rays from supernovas react with the sun to form clouds, which impact the climate on Earth. The findings have been described as the “missing link” to help resolve a decades-long controversy that has big implications for climate science. —Graham Lloyd, The Australian, 19 December 2017

Scientists at the Technical University of Denmark have discovered what they call a game-changing result in understanding how cosmic rays from supernovae – exploding stars – can influence Earth’s cloud cover and thereby climate by being mediated by the Sun. If confirmed, it could alter the equation of climate change with more attention being placed on solar influences which had been dismissed as minor. –David Whitehouse, GWPF Observatory, 19 December 2017

Due to a drop in the number of sunspots and the resulting decrease in total solar radiance (TSI) values, NASA launched a new sensor to study the dimming sun. It is already visible that as the magnetic activity of the sun decreases, influx of Galactic Cosmic Rays (GCR’s) increase. This has been observed by Helium balloon measurements over California. —International Business Times, 17 December 2017
