Celebrated Physicist Calls IPCC Summary ‘Deeply Unscientific’

Former CERN official says 65 prominent IPCC authors have abandoned “scientific rigour.”

Among the documents recently submitted to a UK Parliamentary committee, a live grenade nestles in the straw.

It was written by a scientific luminary, Pierre Darriulat. For nearly 50 years, his professional life has been devoted to particle physics, nuclear physics, condensed matter physics, and astrophysics. For seven years, he was Director of Research at CERN – one of the world’s largest, most famous, and respected laboratories.

The biography included with his submission tells us that Darriulat was spokesperson for one of the two experiments that simultaneously discovered the weak bosons and gave evidence for quarks and gluons being produced in the form of hadronic jets. (more…)

The Other Climate Theory

Al Gore won’t hear it, but heavenly bodies might be driving long-term weather trends.

By ANNE JOLIS

In April 1990, Al Gore published an open letter in the New York Times “To Skeptics on Global Warming” in which he compared them to medieval flat-Earthers. He soon became vice president and his conviction that climate change was dominated by man-made emissions went mainstream. Western governments embarked on a new era of anti-emission regulation and poured billions into research that might justify it. As far as the average Western politician was concerned, the debate was over.

But a few physicists weren’t worrying about Al Gore in the 1990s. They were theorizing about another possible factor in climate change: charged subatomic particles from outer space, or “cosmic rays,” whose atmospheric levels appear to rise and fall with the weakness or strength of solar winds that deflect them from the earth. These shifts might significantly impact the type and quantity of clouds covering the earth, providing a clue to one of the least-understood but most important questions about climate. Heavenly bodies might be driving long-term weather trends. (more…)

CERN Finds “Significant” Cosmic Ray Cloud Effect

Best known for its studies of the fundamental constituents of matter, the CERN particle-physics laboratory in Geneva is now also being used to study the climate. Researchers in the CLOUD collaboration have released the first results from their experiment designed to mimic conditions in the Earth’s atmosphere. By firing beams of particles from the lab’s Proton Synchrotron accelerator into a gas-filled chamber, they have discovered that cosmic rays could have a role to play in climate by enhancing the production of potentially cloud-seeding aerosols. –Physics World, 24 August 2011

If Henrik Svensmark is right, then we are going down the wrong path of taking all these expensive measures to cut carbon emissions; if he is right, we could carry on with carbon emissions as normal.–Terry Sloan, BBC News 3 April 2008 (more…)
