Ozone hole - conviction unsafe

Nature has reported that there is now strong evidence that the current understanding of how the hole in the ozone layer comes into being is wrong.

Markus Rex, an atmosphere scientist at the Alfred Wegener Institute of Polar and Marine Research in Potsdam, Germany, did a double-take when he saw new data for the break-down rate of a crucial molecule, dichlorine peroxide (Cl2O2). The rate of photolysis (light-activated splitting) of this molecule reported by chemists at NASA's Jet Propulsion Laboratory in Pasadena, California, was extremely low in the wavelengths available in the stratosphere — almost an order of magnitude lower than the currently accepted rate. "This must have far-reaching consequences," Rex says. "If the measurements are correct we can basically no longer say we understand how ozone holes come into being."

Dodgy thing, scientific consensus, wouldn't you say?

Don't worry.

The data will probably be ‘adjusted’ with a ‘correction’ factor worked out on the difference between what the ‘consensus’ theory suggests and the actual figures quickly enough that you won't have to worry about it for long...
