Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.
As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades:
How much each change to the atmosphere has warmed the world:
Recommended actions to cut greenhouse gas emissions in the near future:
Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
From this report
I'll note that California is a bit unusual, having imposed energy efficiency standards on buildings decades ago (much of the US didn't) and having actively taken steps to substitute solar, wind, and storage for fossil-fuel based electric generation
25% of all vehicles sold, and 4% of vehicles on the road in 2022. Considering the continued growth it’s likely higher by now. That’s not a huge number but it’s starting to be enough to bring emissions down, especially in combination with the decarbonization of the electric grid.
However, I agree that the best and easiest solution is to move away from the private automobile as the main mode of transit.
Sure, but there are likely 4% more cars on the road now than there were in 2019. One graph I see shows about a 1% YoY growth of the car population in the US. EVs might have saved us from a 4% increase in car emissions, but car emissions are still increasing. I am really not convinced that EVs are the solution to the US's massive car emissions. Ban production of all gas cars in 2024 and then maybe there's a solution in sight.
