How do you do that without completely messing up the supply chains that keep us fed and alive for the next 6 months? The wealthiest people (who also happen to be ones that are a bit more sheltered from the climatic crisis) will still be able to afford food. Billions of poor people would just starve without petrochemical fertilizers and the diesel required for industrial farming and transportation of food. We could've had a smooth transition a few decades ago. Now it's super late and the choice is short term catastrophe vs long term catastrophe. Do you know how much fossil fuels it takes to build and maintain a wind farm or an electric truck? How much petroleum coke is burnt making the cement to build the towers that make walkable cities possible?

The alternative to fossil fuels and the climate crisis is basically an incredibly deadly and uncomfortable step out of the industrialized world. No one is making that decision. It's a fancy trolley problem where the amount of people on the tracks has 10 figures on both sides and blurry timelines.

Just the increase of gas prices due to the iran war is going to cause some fucked up harvests in africa, south america and asia. The poorest farmers aren't able to afford fertilizers. I have a coworker who has ties in Guinea-bissau. The farmers there are basically getting spitroasted by the combination of climate changed caused droughts messing up their cash crops followed by increased oil prices due to wars they have nothing to do with increasing the price of their agricultural inputs. Your simplistic view on fossil fuels will not keep them alive long enough to see the even worst effects of climate change that are coming. If it was easy to stop emitting greenhouse gases we would've managed to do it 25+ years ago.
