To clarify the article. This isn't peak CO2. It isn't even peak pollution. It's peak first derivative of pollution ex. greenhouse gases. We'll get to peak CO2 when emissions of CO2 are net zero, so in a few decades at best. Until then atmospheric carbon and average temperatures will keep rising.
IIRC I had to do some of that calculus stuff before cutting loose on writing upwards and downwards magnetic field continuations for geophysical exploration software suites, so, yep, cheers for that.
That aside, fifty years ago was when the dangers of increasing atmospheric insulation was raised as a serious potential issue in the UN, and fifty years ago was when the think tank ecology surrounding fossil fuel producers started churning articles on ice ages, Climate, who really knows?, killing public transport initiatives, etc.
Hindsight is famously 20|20 but it serves us well to remember past playbooks; it wasn't just pure stupidty, there were people who knew better actively promoting larger cars and greater per capita consumption rather than looking to lower total emissions.
Speaking of pure stupidity, I definately sometimes am.
That said, even when there's evidently plenty of malice around, I'm keeping my fingers crossed that enough cooperators can figure out how to coordinate despite all the damned defectors!
