Zbigniew Jaworowski was born on 17 October 1927. He graduated from the Medical Academy in Kraków with an MD in 1952. He earned his PhD in natural sciences in 1963 and his DSc in natural sciences in 1967.
Jaworowski's works on ice cores were published in Jaworowski (1994, 1992) and in reports Jaworowski (1990, 1992). Jaworowski suggested that the long-term CO2 record is an artifact caused by the structural changes of the ice with depth and by postcoring processes.
Increases in CO2 and CH4 concentrations in the Vostok core are similar for the last two glacial-interglacial transitions, even though only the most recent transition is located in the brittle zone. Such evidence argues that the atmospheric trace-gas signal is not strongly affected by the presence of the brittle zone.[6] Similarly Hans Oeschger states that "...Some of (Jaworowski's) statements are drastically wrong from the physical point of view".[7]
Stephen Schneider said of him that "Jaworowski is perhaps even more contrarian than most, claiming that he can prove the climate is going to get colder through his work excavating glaciers on six different continents, which he says indicates what we should really be worrying about is 'The approaching new Ice Age...'."[8] Jaworowski wrote "The current sunspot cycle is weaker than the preceding cycles, and the next two cycles will be even weaker. Bashkirtsev and Mishnich (2003) expect that the minimum of the secular cycle of solar activity will occur between 2021 and 2026, which will result in the minimum global temperature of the surface air. The shift from warm to cool climate might have already started."[9]
When approached to see if he would bet on future cooling, Jaworowski denied making any prediction, stating "I do not make my own detailed projections. In my paper I referred the reader to B&M paper, and that is all."[10]
Jaworowski wrote that the movement to remove lead from gasoline was based on a "stupid and fraudulent myth," and that lead levels in the human bloodstream are not significantly affected by the use of leaded gasoline.[16]
Jaworowski disputed that ionizing radiation from the Chernobyl disaster was a major catastrophe for human health. After Ukrainian environment minister Yuriy Shcherbak published an article in Scientific American raising concerns about the long-term effects on children in high-radiation areas, Jaworowski pushed back, arguing that increased rates of thyroid cancer could have had other causes and questioning why rates of other types of cancer had not increased.[17] In 1999, he argued that radiation exposure from fallout was "grossly exaggerated". He received criticism from his peers for this perspective in Physics Today and defended his position in 2000.[18] In an interview with the BBC, he referred to the concept of a nuclear winter destroying the biosphere following a nuclear war as "old mythology". Jaworowski also rejected the linear no-threshold model (LNT) for what he considered its poor scientific basis and the "dubious moral aspect of its applications". He argued for dropping LNT from radiation protection regulations and thought that radiophobia was the result of decades of anti-nuclear and anti-radiation propaganda.[4]
