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 climate In two papers1,2 published today in the journal Nature, new results from the CLOUD3experiment at CERN4 imply the baseline pristine pre-industrial climate may have…

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 realized effect is modest at best, and only recoverable when the secular trend in GT is removed.” This “secular trend” is the warming widely believed…

Cosmic Rays and Climate – to be or not to be?

From the “science is still settling” department, the question still seems up in the air to me. On one hand we have Dr. Jasper Kirkby, Head of the CLOUD Experiment, CERN Geneva giving a thorough review showing strong correlations between cosmic rays, solar cycles and earth’s climate. He projects a possible mini ice age by…
