You can acknowledge that there are problems to solve but that doesn't mean that we are doomed as some would have you believe. Even challenging the worst case models is OK as that's how these things work. There's just so many variables that blindly listening to the worst case people without considering other things is foolish.
There is literally nothing you can express to change the mind of a person unwilling to change their beliefs in direct presence of evidence, let alone challenge them when the evidence is indirect, more abstract, or existing in the broader environment beyond themselves.
Frankly speaking, if all the droughts and floods of the past few years in Europe, US, China, etc didn't cause people to wake up, nothing will and they will eventually ponder how we got where we have.
> drastic action that will upend numerous livelihoods and quality of life because we will be able to engineer things to limit effects of warming and probably limit it.
With all due respect, that is absolute bogus. Even the most optimistic scenarios of changing our behaviour tomorrow disagree. We could have done things since the 90s to improve the situation, and it wouldn't have reached the current state.
Whether we "succeed" is not a boolean value conditioned on the average global temp increase < 2.0C. What climate scientists express is that along the way to 2.0C, we will observe many irreversible tipping points, e.g. Ice-sheet of Greenland, change of oceanic currents, yada, issues with polar vortex e.g. increased splitting which causes heat-domes and people suffer and die from heat and so on.
Frankly, I don't expect that anything will change and I have made peace with it.
> "Their excellent climate modelling was at least comparable in performance to one of the most influential and well-regarded climate scientists of modern history," Prof Supran said, comparing ExxonMobil's work to Nasa's James Hansen who sounded the alarm on climate in 1988.
Unwillingness to build nuclear power, which could possibly solve the problem, is a driver of suspicion, which is a driver of denial.
Politicization of social sciences and campus activities, severely damages credibility, which drives denial.
Corruption of global institutions (such as the WHO, in light of COVID origins) and the understandable yet also uncomfortable 'Don't Look Here' approach to NIH, Lancet relationship with Wuhan Biolab Research (it's complicated) generates deep suspicion, and fosters denial.
Big Pharma + McKinsey designed scheme to addict millions with opioids without real consequences, and subsequent embracing of Big Pharma during COVID on totally unquestionable terms aka 'Trust The Science!', although rational from a policy perspective (it's a national emergency), is again, a huge driver of suspicion and therefore denial.
Political voices basically have no credibility in most situations and won't be able to convince anyone remotely skeptical.
I think things like 'Housing Insurance' frankly is one of the better means of social interdiction, it hits people right in the pocket book, and I would hope insurance companies just send out the letter with the graph saying 'well, this is where the weather is going, this is the expected damage, so this is your rate'. That's not political logic.
