Man who discovered Ozone ‘hole’ dies
UK: The British Antarctic Survey scientist Joe Farman, who helped
identify the “hole” in the ozone layer over the southern pole, has died.
Dr Farman published the discovery with Brian Gardiner and Jon
Shanklin in the journal Nature in 1985.
The research prompted the Montreal Protocol, an international
agreement that controls chlorofluorocarbon (CFC) production across the
globe.
Dr Farman, who received many awards, passed away on Saturday aged 82.
Prof Alan Rodger, interim director of the British Antarctic Survey
(BAS), said: “Joe was an excellent physicist and his work changed the
way that we view the natural world.
“After making the discovery of the ozone hole he became an energetic
ambassador for our planet.”
Speaking to BBC News on the 25th anniversary of the reporting of the
hole, Dr Farman said the environment was still being damaged in many
ways.
He criticised politicians for failing to lead on issues like climate
change and said it was “damned stupid” to keep increasing emissions of
CO2 when it was known to be a warming gas.
But he also criticised some of the ways in which climate science was
being conducted. After graduating from Cambridge University, Dr Farman
was appointed as a scientific officer at the Falkland Islands Dependency
Survey, the predecessor of BAS, in 1956.
He became head of the Falkland Islands Dependencies Survey Physics
Unit at the University of Edinburgh in 1969 and returned to BAS in
Cambridge as head of the physics section in 1976.
It was then that he turned his attention to Antarctic ozone
monitoring.
Dr Farman received many awards in recognition of his discovery,
including the Society of Chemical Industry (SCI) Environment Medal, the
Chree Medal and Prize, membership of the Global 500 Roll of Honour, an
OBE in 1988 and a CBE in the New Year Honours 2000.
His last research trip to Antarctica was in 1990, just before he
retired. Farman, Gardiner and Shanklin published their seminal Nature
paper on May 16, 1985. The men described balloon measurements of ozone
in the stratosphere, above 22km in altitude, which showed a precipitous
decline in the concentration of ozone in the Antarctic spring.
Their journal paper also recorded the ever increasing load of
chlorofluorocarbons in the high atmosphere, confirming theoretical
concern that the man-made chemicals could be depleting ozone.CFCs were
routinely used at the time as refrigerants, spray-can propellants and as
solvents..
