Fossil carbon extraction needs to be halted. Worldwide. Close the coal mines, shut down the oil rigs.
Everything else is just rearranging the deck chairs on the Titanic. It's very, very simple: at the beginning of the Paleozoic era, atmospheric carbon was 20x higher than today, a level that the current biosphere cannot survive in. Gradually, over the next few hundred million years, that carbon was sequestered into the ground. We are now digging it back up and burning it, thus returning it to the atmosphere, within a span of decades. You can talk about LED lightbulbs and carbon credits till the cows come home, but the only thing that can halt this is preventing people from burning carbon that came from the ground - and the only way to stop that is to ban its extraction.
"But what will we do for energy?" Lots of things. We have options. Personally I'm a fan of the magic green rocks that give energy forever.
"But how will we power things that need high energy density / make plastics / lubricate my e-bike chain etc" - Oil. We can make it from anything carbon based. It's not even hard. We just have to stop digging it up and burning it.
If you really want to make changes it seems to me that the best place to put effort would be pro nuclear rather than cutting industry to the ground. Serious investment in thorium seems a good place to start.
Understandably, people don't want to give up their existing comforts and habits.
Understandably, people that don't have these comforts feel its only fair that they too get access to them.
Understandably, people don't want to see wind or solar parks or other intrusive installations in their backyard.
Understandably, complex and less that 100% certain science tackling long-term effects and phenomena will be questioned by people with limited trust to institutions of tarnished authority.
People just want the magic tree of energy driven consumption to go on as this is the dominant model of a "fulfilling" life.
What is brewing is a toxic cocktail of denial, blame shifting, panic, snake oil salesmen, speculators etc.
We certainly haven't seen the end of history.
