— middle-aged people alive today experienced a 35% increase in ambient atmospheric carbon dioxide concentration within their lifetimes[0], and we continue as if it’s not really a cause of concern.
— ambient atmospheric carbon dioxide concentration today has apparently never been this high since Miocene[1] (15 megayears ago). It surpassed the last relative peak, from around 300 kiloyears ago, around World War I and Russian Revolution[2] and is skyrocketing since then;
