Actually, the book by Dr. Raskin IS my answer, and I’m writing a book myself on the topic, which is very complex. But you’re right, and I’ll try to answer you as succinctly as I can.
All (social, political, economic, legal, etc.) human actions/scenarios undertaken going forward may be altered, or neutralized, even totally short-circuited by sudden, catastrophic, runaway global warming. This could occur once certain positive feedback atmospheric tipping points are reached. The timeframes/extents of such events are currently unpredictable and unknown, but increasing evidence points to some past climate shifts being sudden, and caused by high atmospheric CO2 and methane — not meteorites or volcanoes.
Atmospheric tipping points are a total wild card.
Many researchers believe that certain tipping points have already been breached. There is a common trend in climate research where the more an aspect of climate change is studied, the worse the situation turns out to be, and the shorter the timeframe for positive action.
My own background and research as a biologist/environmental scientist/psychologist has convinced me that dealing with our current challenges will require addressing (at least) the economic, social, and environmental aspects together. Ignoring any one of these would lead to partial, dysfunctional solutions which would fail to create a humane, sustainable world.
This multi-pronged approach is a complex, but appropriate, strategy for “wicked” problems (as defined by Thomas Homer-Dixon). It generates a diverse range of possible future scenarios (with over 450 studies done so far). Dr. Raskin identifies common elements and reduces the number to roughly a dozen, and explains each one with its pros and cons. There is no “one size fits all” solution. Dr. Raskin has been working on these issues for about 40 years. He is very clear and thorough, and his work has been peer reviewed as the best of the 450. I urge you to to read his book.
But in the final analysis, the unpredictable tipping point situation may make all our best efforts and scenarios, yes — moot. Bottom line is that our survival as a civilization or as a species doesn’t matter to Earth. But in the meantime, each one of us has to do the best we can to create the future we want — regardless — however we define that. For me, I choose humane, beautiful and sustainable.
And then there’s AI — another total wild card…
Well, that’s not a few words, but hope I’ve cleared up my take… ;)
