This paper identifies a number of “positive tipping points” on climate change that can help counteract the risk of reaching negative tipping points such as glacier melting and methane release. They identify the shift to solar and wind power, electric vehicles, and heat pumps for heating and cooling buildings. These seem very market- and consumer-driven to me. So these are feedback loops that have been gathering some steam, and maybe governments can do relatively small things to reinforce them in the hopes of getting them to a takeoff point where they are self-sustaining and able to counteract the negative feedback loops that are out there. It is somewhat heartening to realize that the renewable energy and electric vehicle revolutions are farther along outside the US than inside, and we are not getting this impression I believe because of effective oil and gas industry propaganda here. Because those companies and their lobbyists understand these positive feedback loops too, and they are evil or at least amoral in the pursuit of short term profit at the long term expense of human civilization on Earth.

From what I understand (outside this article), adoption of heat pumps and building electrification is farther along in the U.S. than elsewhere. This is interesting – how did we manage to move away from heating buildings with coal, oil, and gas directly decades ago if this decreased the profits of the all-powerful fossil fuel industry? Were they just asleep at the switch, or were the economic incentives just that strong? Is it because we made the choice to fund electric infrastructure through a decentralized, regulated electric utility industry? And once we built that infrastructure, the economic incentives became too strong to resist. Whereas we have not built the infrastructure to support the electric vehicle transition, and the fossil fuel/automobile/highway construction industry is successfully fighting that tooth and nail through propaganda and (legalized, by our corrupt Supreme Court) political corruption. (Remember that currently, highway construction has dedicated funding from gas taxes. And auto dealerships make more money from servicing and repairing fossil fuel powered vehicles than they do from selling them.)

Note the oil and gas industry could have been decentralized and regulated too, that is just not the path we went down a century or so ago. It’s too late for this, but economic incentives are going to push in the direction of building the charging infrastructure, because it is just a better, cleaner, and cheaper way to get around overall. So by pushing for this policy, however strongly and effectively the forces of darkness have been pushing against it lately, we are working to reinforce a positive feedback loop that can eventually tip and become irreversible.

I know, a lot of electricity is still generated with fossil fuels at this point. It is still more efficient from what I understand. And slowly but surely, renewables are chipping away. Add modernized nuclear technology to this mix, like the small modular reactors, and keep pushing toward that longer-term dream of fusion power.
