Extractions: Mario Molina In 1973 Mario Molina was a postdoctoral researcher working in the laboratory of F. Sherwood Rowland at the University of California at Irvine, just south of Los Angeles, when he made an unsettling discovery. He had been investigating a class of compounds called chlorofluorocarbons , or CFCs. CFCs were used as refrigerants , aerosol sprays, and in making plastic foams. Molina wondered what happened to them once they were released into the atmosphere. This was a hypothetical study, but his results showed disturbingly that CFCs could, in theory, destroy a compound called ozone under the conditions that exist in the upper atmosphere. Far above the earth's surface, a thin layer of ozone floats, protecting us from the sun's ultraviolet radiation . Molina, just a young scientist at the time, was nervous about showing Rowland his theory of how CFCs might destroy ozone . But if CFCs really could wipe out ozone, the whole world would be in trouble. Rowland took his protog seriously. Over the next two decades he and Molina became voices crying in the wilderness, alerting the world to the danger of CFCs and ozone depletion. They weren't always heeded. Bans on CFCs in aerosol sprays went into effect first in the United States in 1978, and later in Canada, Norway, and Sweden. CFC use for other purposes only increased. Scientists, activists, politicians, and CFC-producing companies would argue for years over the merit of Molina's theories. Mario Molina was born in Mexico City, where Marioâs father was a successful lawyer and a diplomat. As a child, Mario was fascinated with chemistry and converted one of the bathrooms in his family's house to a chemistry laboratory for himself. His aunt, Esther Molina, was a chemist, and she encouraged and mentored the boy by helping him carry out more advanced experiments than normally possible with a child's chemistry set. Recognizing his passion for science, Marioâs parents sent him to a boarding school in Europe, where they thought his fascination with science would be nurtured.

Extractions: Dr. F. Sherwood Rowland agreed to accept the 1997 Nevada Medal on September 11, 1995, and exactly a month later, was notified of his Nobel Prize in Chemistry. Both the Nevada Medal and Nobel Prize recognize his atmospheric studies which led to an understanding of how the ozone layer forms and decomposes. The Royal Swedish Academy of Sciences said Rowland's research has "contributed to our salvation from a global environmental problem that could have catastrophic consequences." In 1974, Rowland was the world's first scientist to point out the mechanisms by which chlorofluorocarbons (CFCs) could destroy the ozone layer, which protects life on Earth from harmful ultraviolet solar radiation. Rowland's theoretical insights and predictions have been verified by scientists throughout the world, and have done much to strengthen international efforts for the preservation of stratospheric ozone. The research of Rowland and his colleague, Dr. Mario Molina, eventually led to legislation in the United States and other countries regulating the manufacture and use of CFCs, and to the Montreal Protocol, the first international agreement for controlling and healing environmental damage to the global atmosphere. Rowland's recent studies of the impact of methane gas on the atmosphere have shown atmospheric concentrations have been steadily increasing at about one percent per year since 1978. The excess release of methane is contributing to the "greenhouse effect," the gradual warming of the earth's surface.

Extractions: Chlorofluorocarbon (CFC) compounds were first synthesized about 70 years ago, entering commercial use soon afterwards, first in a refrigerant gas and then in aerosol propellants. Yearly production rose exponentially from the 1950s, reaching 100,000 tonnes per year in the mid-1960s. Concentrations in the atmosphere rose steadily, but stayed well below the levels at which they could be detected using the instruments of the time. So their increase went unnoticed until British scientist Jim Lovelock first found CFC-11 in Irish air at a level of approximately 50 parts per trillion by volume with an electron capture detector - an extremely sensitive instrument of his own invention. He then made extensive measurements on board ship from England to Antarctica, and determined that it was clearly detectable everywhere in the surface atmosphere. In late 1973, intrigued by the presence of a new component of the Earth's atmosphere, Mario Molina and I began investigating the eventual atmospheric fate of CFCs. Most molecules released to the atmosphere are removed within hours to weeks by one of three general processes: by absorption of sunlight (photolysis), by dissolution in water (rainout), or by reaction with hydroxyl radical, HO, or ozone, O3 (oxidation). However, CFCs are transparent, insoluble and unreactive to atmospheric oxidizing agents; so none of these processes affects them and they can last a long time in the lower atmosphere.

Extractions: When US President George W. Bush wanted to know the truth about climate change he put 13 specific questions to the National Academy of Sciences. A team of experts provided the answers, confirming that global warming was a real problem. A few weeks later the US government withdrew from the Kyoto protocol. Program Transcript Terry Lane: Professor Sherwood Rowland is Professor of Chemistry and Earth Systems Science at the University of California, Irvine, and hes been in Australia this past week as a guest of the Australian Academy of Science. Professor Rowland shared the Nobel Prize in Chemistry in 1995 for the work he did in atmospheric chemistry and in particular, as I said, on the formation and decomposition of ozone. Well in 2001, the Bush administration commissioned the National Academy of Sciences to quickly answer some questions about global warming, and Professor Rowland was one of the scientists who was involved in answering the Presidents questions. Now I recorded this conversation with Sherwood Rowland on Thursday, just before he left to return to the United States, and I asked him if it was a fact that the Bush White House was generally sceptical about global warming. F. Sherwood Rowland: At that time, the White House apparently had two factions that were in disagreement about this, and one of the factions believed that global warming was important and that something should be done about it. And they were running an educational program in the White House, with people coming in every week to talk about it, and they were talking with the National Research Council about who the appropriate people were to be participating in that. The question that was coming up was also the Inter-governmental Panel on Climate Change, the IPCC, which had a report that was just coming out about climate change and about the various aspects of that.

Extractions: Your Majesties, Your Royal Highnesses, Ladies and Gentlemen. My friends, Paul J. Crutzen and Mario Molina, and I are most grateful for the honours bestowed upon us today, for the Nobel Prize is the ultimate in recognition in the scientific world. It is immensely satisfying to us that our efforts to understand the chemistry of ozone in the atmosphere have been judged worthy of this honour. The atmosphere and its manifold changes have held fascination for men and women ever since human beings have trod this Earth. Its study played an integral role in the evolution of natural philosophy from which all of our present sciences have sprung. The scientific and technological developments of the past several decades, not available to our predecessors in past millennia, have provided the theories and tools which have now permitted us to develop a significant understanding of several atmospheric processes which affect the concentration of ozone in our stratosphere.

Extractions: DURHAM The University of New Hampshire College of Engineering and Physical Sciences will host Nobel-prize winning atmospheric chemist F. Sherwood Rowland in October as the 2003 Harold A. Iddles lecturer. Rowland shared the 1995 Nobel Prize for chemistry for being among the first to warn that pollutants called chlorofluorocarbons, or CFCs, were eating a hole in the earths stratospheric ozone layer, which protects against harmful ultraviolet radiation. Subsequent research on CFCs led to several countries banning their use in the 1970s and, in 1987, to the Montreal Protocol, the international accord to sharply reduce CFC emissions. Currently the Donald Bren Research Professor of Chemistry and Earth System Science at the University of California, Irvine, Rowland is now investigating the effects of hydrocarbon and halocarbon composition of the atmosphere, with particular emphasis on the greenhouse effect. His lectures will cover both past and present research.
