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: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world. About 1C of total warming. Second chart: about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability. Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases. About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

The details on this are not promising:

Nearly 23% of new vehicles sold in California in 2025 were considered zero-emission vehicles, though EV sales were down in the state and across the U.S. compared to the year prior.

...

In the fourth quarter of 2025, only 18% of new cars sold in the state were zero-emission.

It needs to be 100% in the not-very-distant future, and that's going to be really tough without a sharp reduction in prices, which isn't likely to happen due to tariffs pushing prices up.

We're rat-holing a bit here. Yes, tech can always be better, but those attributes aren't what's slowing down EV sales. The Model 3 became the best selling car in the USA despite those characteristics.

Sales are declining for other reasons. My suggestion here is that one of the most obvious reasons sales may be declining is that it's a lot more expensive to "fuel" an EV than it was just a few years ago. Utility prices and NEM policies have driven op costs a ton.
