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.

It's not a typo: plug-in hybrids are used, in real word cases, with ICE much more than anticipated.

In the EU, fuel consumption monitoring devices are required on new cars. They studied over 10% of all cars sold in 2021 and turns out they use way more fuel, and generate way more CO2, than anybody thought.

The gap means that CO2 emissions reduction objectives from transport will be more difficult to reach.

Thruth is, we need less cars, not "better" cars.

When the average car price is greater than $48,000 in the US now, one doesn't have the luxury of choosing something for eco aspirations. Many US states are huge sprawling affairs, and many people have to drive large distances with frequency for work, life, errands.

Example: I can't even make it to my state's border in the longest-range currently-available electric car, and would end up in the middle of nowhere with no services, no charging stations, no infrastructure. In winter, it would be half that distance or less.

I am also probably the perfect demographic for a plug-in hybrid, and could utilize the plug-in aspect for shorter trips frequently. However, there's no reason to replace a perfectly functional vehicle in good mechanical shape with an expensive fiscal debt as well as the carbon debt that new vehicle would also create.

If one does not understand the scale and size of places, one can't comprehend how range anxiety (more like range reality) truly fits in.

However, if America was truly forward-thinking, they'd nationalize the railroads and put a focus on rebuilding the old rail infrastructure that existed over a century ago to entirely eliminate the necessity of long-distance personal vehicles.

Bro, I love in the middle of nowhere. My boss drives 2 hours a day to get to our work. So do a handful of other people with all electric vehicles.

It's an emotional response, not a logical one.

Try figuring out to drive 120 miles vs 700. Try an 8 hour drive-day. Try being in a situation when your family has a problem and you have 1,700 miles to drive. Do you spend almost fifty grand on an electric car and plotting charge points that may or may not exist, or a vehicle that can let you cross multiple states without stopping? I hate gas. I would love a Toyota Mirai. Leaving home to get one US state over is a larger distance than the entire width of Germany. It's a reality response, not emotional.
