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.

If I couldn’t charge at home, or regularly took very long trips, the EV wouldn’t make sense.

Precisely. Until the ease of refuelling becomes more competitive with ICE cars for the average user, EVs are not going to see mass adoption.

I just looked and my EV (a model 3) is 50 pounds heavier than my other car (a Lexus hybird sedan). That’s a pretty negligible difference.

The weight difference between an EV and a HEV/PHEV usually isn't as dramatic as between an EV and an ICE vehicle. Plus you're not comparing like with like (Tesla vs Lexus). A better comparison would be, for example, the Hyundai Kona EV (curb weight 3,803 lb) versus the gasoline Kona (2,855 lbs) - Source. That's nearly 1,000 lbs of extra weight due to the battery pack and hardware.

All that extra weight means more power required for propulsion, which in turn means larger and more expensive battery packs. While this has gotten better over the years compared to previous gen EVs, it still makes EVs costly to buy and potentially repair.

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.
