“From 1956 onwards he published a series of papers on the topic, partly based on advanced calculations of the absorption of infrared radiation, and he made use of early electronic computers. Plass predicted that a doubling of CO2 would warm the planet by 3.6 °C, that CO2 levels in 2000 would be 30% higher than in 1900 and that the planet would be about 1 °C warmer in 2000 than in 1900. In 2007 the IPCC Fourth Assessment Reportestimated a climate sensitivity of 2 to 4.5 °C for CO2 doubling, a CO2 rise of 37% since pre-industrial times and a 1900-2000 warm-up of around 0.7 °C.”
I read Plass’s paper “Carbon Dioxide and Climate”, published in 1959, Scientific American, while at McGill University in 1970, for a class I was taking in marine geology.
Later, I read the MIT group’s Club of Rome Report “Limits to Growth” in 1972.
Greenpeace was founded just before that report, in 1971.
From Plass to “Limits” - almost exactly 60 and 50 years ago respectively.
And yet here we are - still in denial.
Of course we have excuses, reasons even - galore, for our failure to act.
When the denial ends, if it ends, will the religious bent and herd mentality of the human being collapse the stock market ??
And if it does - the emergency would move from “long” to short, now wouldn’t it ??
