CERN's CLOUD experiment results suggests industrial revolution reduced cloud cover, cosmic rays have an impact too

From CERN Our planet’s pre-industrial climate may have been cloudier than presently thought, shows CERN’s CLOUD experiment in two papers published in Nature. CERN experiment points to a cloudier pre-industrial…

Using cosmic rays to reveal Earth's thunderstorm processes

From the University of Groningen: Exploding stars help to understand thunderclouds on Earth How is lightning initiated in thunderclouds? This is difficult to answer – how do you measure electric…

Link between Cosmic Ray Flux and Global Temperature found

From the paper in PNAS:(h/t to Dr. Leif Svalgaard) Our results suggest weak to moderate coupling between CR and year-to-year changes of GT,” they write. “However, we find that the…

This is the second video in the TEDed / CERN series created for the TEDxCERN event held on 25 September 2014. Jasper Kirkby explains why scientists need to understand more…

Paper: Influence of solar cycles on climate change during the Maunder Minimum

Both observational and proxy records of climate change often show quasi periodic variations similar to solar activity cycles over a wide range of time scales. However, the detailed mechanism and…
