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 average modern person, by one calculation, spends more than 1,600 hours a year to pay for their cars, their insurance, fuel and repairs. We go to jobs partly to pay for the cars, and we need the cars mostly to get to jobs. We spend four of our sixteen waking hours on the road or gathering the resources for the car.

Since the average modern American, by one estimate, travels 7,500 miles a year, and put in 1,600 hours a year to do that, they are travelling five miles per hour. Before people had cars, however, people managed to do the same – by walking.

By contrast, a person on a bicycle can go three or four times faster than a pedestrian, but uses five times less energy in the process.

Electric catrs still pollute massively. Mainly tire and break dust (more than ICE cats because they are heavier). Nevermind that cars dependency is terrible and unsustainable (both economically and environmentally). Make cities for people not cars.

Plus show me one example of where car dependency has worked. It's always "just add more lanes". Yeah just ask Texas how their 26 lane highway is going.

Plus we don't need to be paving over airable farmland for people cosplaying as rural folk. We have about 5 parking spots for every single car in the United States. Seems like a great use of land.

Yeah, as I explain elsewhere, I wasn’t pushing EVs over bikes. I was just saying the framing of “pro-pedal power” in this article is the exact type of shit right wingers latch onto and never shut up about. I can hear them now: “LIBRUL ANARCHIST COMMUNISTS’ ideal world is one where you eat crickets, can never travel more than 15 minutes from your house, can’t eat hamburgers, never get a vacation, never have children, and you have to pedal-power your home appliances!”

They will always find a way to make a stupid argument like that, of course. The 15 minute cities thing is a great example. How much did they shout about how “you’ll never get to see your sweet old grandmother! The LEFT wants your grandma to die alone!” in regards to the concept of 15 minute cities? But regardless, we as the pro-not-boiling-alive group need to be smarter about the type of solutions we pose. They will take this type of sloppy idealism and talk about how you’ll be powering your tv with pedals or whatever.

The way we present the solution matters. It’s literally the biggest hurdle we face, because we need support. Wistfully discussing the glory of pedal power for everything just serves up the propaganda on a silver platter.

That was my point. Not that everyone should drive.
