4 Comment on Science and Media The article you read from Science argued that because a study failed to be replicated that fraud was involved. Replication and rejecting hypotheses is part of the scientific process. You have to distinguish a scientific dispute from misconduct. (Grief & Merz, 2007)

5 Science & Policy: Air Pollution In early December of 1952, a cold fog descended upon London. Because of the cold, Londoners began to burn more coal than usual. At the same time, the final conversion of London's electric trams to diesel buses was completed. The resulting air pollution was trapped by the heavy layer of cold air, and the concentration of pollutants built up dramatically. The smog was so thick that it would sometimes make driving impossible. It entered indoors easily, and concerts and screenings of films were cancelled as the audience could not see the stage or screen. Medical services compiled statistics and found that the fog had killed 4,000 people—most of whom were very young or elderly, or had pre-existing respiratory problems. Another 8,000 died in the weeks and months that followed. (Grief & Merz, 2007) Killer Smog in London Dec 4-9, 1952 http://www.martinfrost.ws/htmlfiles/smog2.jpg

New regulations were put in place restricting the use of dirty fuels in industry and banning black smoke [particulates]. These included the Clean Air Acts of 1956 and of 1968, and the City of London (Various Powers) Act of 1954 Killer Smog, Dec 4-9, 1952 Central Press/Hulton Archive/Getty Images
