“How many of you think the world is cooling?” That’s what Steve Schneider asked the studio audience of the Tonight Show with Johnny Carson in September 1977. And when the majority put their hands up, he explained that the recent cooling trend had only been short-term. Though the unscripted poll meant Steve wasn’t invited back to the programme, through the summer of that year he had brought climate science to US national TV. The appearances typified Steve’s efforts to bring climate change to the world’s notice – efforts that would later draw attention of a less desirable sort.
Building on his earlier high profile research, Steve had just published ‘The Genesis Strategy: Climate and Global Survival’, predicting ‘demonstrable climate change’ by the end of the century. Whether human pollution would cause warming or cooling, he argued governments should copy the biblical story where Joseph told Pharoah to prepare for lean years ahead. In a decade already torn by rocketing food and oil prices, the advice resonated with many who wanted to head off any further crises.
Some scientists criticised Steve and those like him for speaking straight to the public. In particular, climate science uncertainties were so great that they feared confusion – like that over whether temperatures were rising or falling – was inevitable. That dispute grew from a basic question about science’s place in society. Should researchers concentrate on questions they can comfortably answer using their existing methods? Or should they tackle questions the world needs answered, even if the results that follow are less definite?
At a meeting to discuss climate and modelling research within the Global Atmospheric Research Programme (GARP) in 1974 near Stockholm, Sweden, Steve pushed for the second approach. Given the food problems the world was struggling with at the time, it seemed obvious that climate change impacts like droughts, floods and extreme temperatures would bring famines. “I stood alone in arguing that we had to consider the implications of what we were researching,” Steve later wrote. While some attacked him angrily, saying they weren’t ready to address these problems, conference organiser Bert Bolin agreed that socially important questions must be answered.
The suggestion was also controversial because it meant blurring the lines between climate science and other subjects, such as agriculture, ecology and even economics. The director at the US National Center for Atmospheric Research (NCAR) in Boulder, Colorado, where Steve worked, warned that crossing subject boundaries might cost him promotion. But he responded with characteristic wilfulness, founding a journal doing exactly what he was warned not to. Read the rest of this entry »
