The time for debate was 60 years ago. The time for action was 40 years ago. We are just beginning to feel the consequences of our inaction.
While we crow about how cheap solar has become for the developed world, impoverished nations will continue to use dirty power because we didn't give a shit when we were informed about the consequences and they'll go by our example.
I'm fine being called a doomer, that just seems to be the last ad hominem of desparation for those that want to squint hard enough to imagine hope. It doesn't change the reality, our nature, and our lengthy track record of hurting the many long term to enrich the few short term. We can't even agree that those people need to be stopped, lest we damage our beloved ~~society~~ economy. The only difference from what humanity has always inflicted upon humanity out of unrestrained selfishness is the scale of that damage that technology affords.
Show me humanity has the will to confiscate the wealth of even a single petrochemical billionaire who is rich off earth's climate destabilization and use their funds in their entirety to mitigate further damage to the climate. Show me how our civilization is going to sharply switch from an unsustainable growth/metastasis seeking economic model to one that grows slowly by design and seeks homeostasis/equilibrium with our only habitat. Then maybe we're getting serious. Any minute now....
As it is, trying to sell solving the man made climate apocalypse as a job for market capitalism is about as morbidly hilarious as it gets. You might as well put your faith in the Republican Governor's Association to restore national abortion rights. Maybe make Jeffrey Dahmer a posthumous ambassador for the sanctity of human life while you're at it.
This is how a capitalists "solve" climate change: https://www.scientificamerican.com/article/exxon-knew-about-climate-change-almost-40-years-ago/
The way we live today in these numbers is incompatible with having a stable planet hospitable to human life. We've clearly chosen the former over the latter.
