Here’s a story for the dwindling number (I hope) of climate change skeptics who still look forward to business-as-usual, or more-of-the-same as a blueprint for the rest of the 21st century. A HuffPost report in November reveals that, way back in 1956, the coal industry accepted the reality of global warming and did not feel threatened by it (the problem lay one generation in the future!). The same is true for the oil industry, according to a spate of lawsuits brought against it by various groups and several US States. In December 2019, Exxon won a major climate change lawsuit brought against it by the state of New York, but there are many more on the way.
The remarkable thing here is that the science of impending climate change was uncontested as long as the threat to the profits of fossil fuel corporations lay decades in the future. Here is the paradox at the heart of the debate about climate change. In the early days of global climate modelling, in the 1970s, the models were relatively unrefined and scientists themselves did not stake strong positions based on the results of their own models. Additionally, the majority of scientists subscribed to the myth that science has to be neutral in order to serve as an impartial referee that floated above the discussion, distributing facts where necessary. In reality, the discussions on the ground were becoming messy. The science began to be disputed as the soon as the deadline for meaningful action neared. Powerful polluters, mining companies, oil corporations, muddied the waters (both literally and intellectually) with arguments that played on statistical uncertainty to kick the decision a few decades down the road.
Meanwhile scientists sat back and redoubled their efforts, striving for ever greater accuracy in their models. They reasoned, logically, that once their results achieved greater accuracy, people would come round to their point of view. But that is not the way the world works. It has little place for logic and reason. So they toiled on, with ever more dense reports of double- and triple-checked facts and innumerable citations. Meanwhile the world went on guzzling gas and emitting CO2, methane, and worse. This is the point when the world drowns in despair or A MESSIAH APPEARS. Lo and behold! We have our unlikely messiah. Hundreds of thousands of school children, young people. Their face is that of Greta Thunberg whose single-minded focus has made her the global symbol of the movement.
If we look at simple facts, solutions to the problem are much more doable than we think. Elon Musk is mocked for saying that 10,000 sq. miles of the Nevada desert covered in solar panels could produce all the energy requirements of the United States. He’s right of course, but this is only intended as an example of scale. It wouldn’t be safe or desirable to have the entire nation’s energy needs produced at a single source. The following is a better example. An engineer acquaintance, Klaus Turek, calculates that in the case of a temperate country like Austria, just 0.391% of its surface covered with solar panels is sufficient to meet its electricity requirements. That works out to about 328 sq. km. for the whole country. The area covered by buildings is 2.4%, however (2,013 sq km approximately). Therefore, just 16% of the currently available roof space would be sufficient to cover all of Austria’s current electricity needs, with plenty left over for expansion.
