Josef, thank you for taking the time to express your thoughts and concerns regarding this truly complex issue. I’m not a climate scientist myself and agree 100% with the statement that earths climate is way to complex to pinpoint it to one variable. I would also agree with the incentive structure in current academia to be disincentivizing open ended research.
However I can’t ignore that my personal choices and actions have consequences. Consequences that may be more or less harmful to my fellow citizens of the earth and the environment around me. I personally try to optimize my lifestyle to avoid as much harm as possible. Others might not share these values or might refuse to be aware of the consequences of their actions, but that’s not of my business. I might argue that people who live in a harmful way towards their fellow citizens and environment are violating the NAP (non aggression principle) but usually even that is causing resentment because everyone thinks they are doing their best already. We’re not. There is room to grow, always.
