In an open access paper published in the journal Science (link is external) today, CERN’s CLOUD experiment has shown that biogenic vapours emitted by trees and oxidised in the atmosphere have a significant impact on the formation of clouds, thus helping to cool the planet. These biogenic aerosols are what give forests seen from afar their characteristic blue haze. The CLOUD study shows that the oxidised biogenic vapours bind with sulphuric acid to form embryonic particles which can then grow to become the seeds on which cloud droplets can form. This result follows previous measurements from CLOUD showing that sulphuric acid alone could not form new particles in the atmosphere as had been previously assumed.
When government gains the power to control the use of private property, it becomes possible for the politically dominant to profit by high commodity prices using government regulation to constrain supply. One merely drives competitors out of business by manipulating the perception of risk to a land use preferred by a democratic majority.
