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.

Plug in hybrids make a lot of sense during this transitional period of rapidly advancing battery technology and incomplete deployment of charging infrastructure.

Building a small, relatively cheap factory for manufacturing a small number of super expensive, pavement princess trucks is less risky than making a large investment in a megafactory capable of producing a meaningful number of affordable cars. That big car factory would need the market to demand its products for a long time for the investment to pay off. For example, if there's a big leap in battery tech in the near future, the car manufacturer would take a loss - either they continue to offer outdated EVs and sell fewer than projected (only utilizing a fraction of the factory's maximum output, while still paying taxes and maintenance on a larger facility), or they throw away their expensive, brand new factory tools and build expensive new ones for manufacturing cars with the new batteries.

Meanwhile, charging an EV at home still isn't possible for a lot of people, and quick charger stations aren't available yet in a lot of areas. However, a plug in hybrid can be adequately charged overnight by a standard home electrical outlet, letting it act like an EV for quick trips around town. Meanwhile, longer trips into not-yet-electrified areas are still possible thanks to the ICE, and the range can be quickly topped up at a gas station. More plug in hybrids on the roads also generates demand for building charging infrastructure - if someone just has $5 to spend on gas, they could get more miles by spending it on electricity at a quick charger.

Honestly plug in hybrids are the worst of both worlds.

There was a study recently from Europe that found the vast majority of people with plug in hybrids hardly every plugged them in, and drove them like normal cars. That defeats the entire point of a plug in hybrid, and now you are carrying a heavy battery everywhere that you are not fully using. Which makes the car less efficient than a normal hybrid!

Not necessarily. In our case, we have a hybrid SUV that we’ve used on several road trips, however most of the driving is within the 40 mile range. At the time, there was no plug in hybrid option, but if there was, it would have been perfect. Battery for most daily driving, but no range anxiety for any road trips.
