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.

You might notice I said we should “move away from cars” which obviously includes building alternatives not just abandoning cars.

If you’re responding in good faith and genuinely wanting to learn about this topic, you might try looking into how other countries (I presume you’re American or Canadian?) manage with fewer cars. For example, other cold countries like Finland and northern Japan walk, bike, and use public transportation all year round, even in -20 weather. Check out this video. Totally possible. Obviously, the US and Canada had big cities before the invention of cars, so I’m not sure why you think there are no possible alternatives to cars.

Finland and northern Japan are microscopic compared to Canada (or the USA). The reason it's feasible there does not make it feasible here.

I hear this argument a lot but it doesn’t make any sense. The size of the country doesn’t matter for your daily commute.

It’s also nonsensical because living without cars was feasible in Canada and the US 100 years ago, and remains feasible in many small towns and big cities. Winnipeg, Calgary, Minneapolis, Los Angeles, Kansas City… they all had efficient and extensive tram and bus systems in the pre-war era. The walkable neighborhoods made before cars remain some of the most valuable and sought after real estate in North America.

Maybe in the cities. However in the 20s, for rural areas, Horse and carts were still in use. Automobiles replaced them.

A lot of rural areas built walkable town centres which still exist today. But sure, some areas will always need cars. That said, over 80% of the population of US and Canada today lives in urban areas, so let's at least work on that 80%. It doesn't have to be all or nothing.
