CERN video: Cloudy climate change – How clouds affect Earth’s temperature

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 about aerosols and clouds in order to predict the rise in the Earth’s surface temperature with more precision. The CLOUD experiment at CERN aims to…

Cosmic Rays, Sunspots, and Beryllium

Guest Post by Willis Eschenbach In investigations of the past history of cosmic rays, the deposition rates (flux rates) of the beryllium isotope 10Be are often used as a proxy for the amount of cosmic rays. This is because 10Be is produced, inter alia, by cosmic rays in the atmosphere. Being a congenitally inquisitive type…

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…
