Can they really prove this? Of course: In a 1975 paper in Science, she asserted that aerosols caused "heating of the atmosphere near the poles... published in the Journal of Applied Meteorology in 1979. It focused on albedo, or the measure of how well a surface reflects sunlight. Their second paper, published in the Journal of Geophysical Research in 1981, explored "increases in the concentration of atmospheric carbon dioxide." Or perhaps you prefer: Before arriving at Ford, Plass had published a series of eye-grabbing pieces on the climate, including a 1956 article in the magazine American Scientist titled "Carbon Dioxide and the Climate" and a 1956 paper in the journal Tellus titled "The Carbon Dioxide Theory of Climatic Change." And so on. In case you should think that these papers were ignored - and therefore the auto-makers, who, errm, sponsored them before they employed these people, errrm, had some kind of inside track, E&E helpfully destroys its own case by noting that Plass' findings reached the highest levels of the U.S. scientific community.
Yup, you read that right: their evidence was that they published public research papers. In other words, the "GM, Ford knew", with its implication (actually, more than an implication: E&E lies directly: More than two decades after GM and Ford privately confirmed the dangers of climate change...) of sekrit knowledge, is utter drivel: whatever they knew was public. This is the fruit of a months long investigation?
All of this stuff is stupid. It is done by idiots trying to plump up their public profile, and with a future eye on lawsuits, which judging by Alsup will fall over horribly because they will learn nothing from that case. The idea that people really knew with any confidence about GW in the 1960s is obvious drivel; see previous posts; at best, you could claim that the first IPCC report in 1990 is a good date, but even that is doubtful, if you've ever read the thing. The idea that the oil companies, or anyone else, knew anything sekrit is also drivel: #everyoneknew.
* More drivel, this time a Twat from Alexandria Ocasio-Cortez: I’m willing to hold you accountable for lying about climate change for 30 years when you secretly knew the entire time that fossil fuels emissions would destroy our planet. Fuckwit.
