The phony ‘consensus’ on climate change

The end is near …

… that is, for the myth that scientists have reached “consensus” on global warming and climate change caused by humans.

The theory (more accurately called a religion for the redistribution of wealth) has taken a number of body blows in recent times — although the climate-change lobby is still straining to impose its view on the world. For example, Time magazine issued a screed headlined “Who’s Bankrolling the Climate-Change Deniers?” The piece wonders why any doubts linger. Time says, “an overwhelming scientific consensus that says it does.” (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…)

The Cloud Mystery

by Gordon Fulks

I finally had a chance to watch the movie about Svensmark’s work on “The Cloud Mystery” and found it fascinating.  Both Svensmark from Denmark and Nir Shaviv from Hebrew University in Israel make a strong case for a galactic cosmic ray origin for climate change over periods as short as a decade to as long as 150 million years:

The short term variations in the galactic cosmic rays and therefore the cloud cover are caused by variations in the solar magnetic field frozen into the solar wind.  This large spiral magnetic field is carried out to about 100 AU in roughly a year by the supersonic solar wind traveling at 400 km/sec.  It modulates incoming galactic cosmic rays by convecting them out of the solar system as they attempt to diffuse inward.  Sunspots are the visual manifestation of the Sun’s magnetic activity.  We have records of them going back to Galileo in 1610.

Very long term variations in the cosmic rays reaching the earth are caused by the solar system’s orbit about the center of our Milky Way galaxy.  When we enter one of the major spiral arms of the galaxy, the galactic cosmic ray intensity increases which increases our cloud cover and cools the earth.  The data show periodic cooling of the earth over periods of 150 million years corresponding to entry into the spiral arms.
