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.

Am I wrong, or does Japan not have at least one car per household (obviously less in the cities, but the same is true with New York). I know this is less than the average American, but I'd suggest the reason for this has more to do with economics and space than public transportation options. In New York City, I can take the bus (why THE FUCK would I?) The rickety subway (which is quite good, despite its obvious age and lack of maintenance) The Railroads, or peddle down a hot, or frozen street on a Citibike. When all else fails, I can walk, which most for most places (in Manhattan at least) is a great option.....

.......Yet, traffic in New York City is still horrendous, and I still have a car -- Because I need a car to get to places those other options can't reach, and I'll bet that's true for a lot of people. I don't have TWO cars like those in rural areas because of the expense, the difficulty of parking, and I have a decent public transit system.

The second point being you can't get rid of cars. They're required for too many people to live and work. That's true for NYC. That's true for Japan and I'll bet it's even true for everyone's Darling Finland, which it doesn't take much googling to discover is true. The best you can hope for is 1 car per household ... unless we're going to start raising cities and completely redesigning them and even then I'm skeptical.

Indeed, it's not a question of cars vs. no cars. It's about the extent of car dependence. We will always have some cars, even Tokyo and Amsterdam has cars, but right now, in the US and Canada, we are often forced to travel by car because we have no other options.

It's also not just about whether one owns a car, but how much we use cars. The fact that most Japanese or Finnish families own one car doesn't mean much on its own. A lot of those families only use their car a few times a month. Most commute by train or bus, or just walk to the grocery store. As bad as New York city traffic is, it would be much worse if you didn't have options like subways and good sidewalks. It's a spectrum, not black and white. But, right now, we are FAR on the car-centric extreme.

I will say that for most trips into Manhattan I'll use public transportation (Train or Subway) just because it's easier and less subject to traffic jams. It's also just nice to read a book while traveling to work. Overall it's a less stressful experience. Almost anything in the outer boroughs I need a car to get to (Parts of Brooklyn might as well be on the moon) However Manhattan is very different then anywhere in San Francisco, whose public transportation I found mind numbingly slow and less frequent.

One place that could use some major improvement is cross-country train travel. My wife and I took a train to Montreal about five years ago and I swore never to do this again. It was painful how slow and shitty that experience was. It really wouldn't take a whole lot to improve this, the bar is that low. I would have paid more money! High speed rail will never get you to the West Coast as fast as an airplane, but if the experience and ease is worth it you can get more customers. However it doesn't seem like Amtrak gives a single good God damn. They might as well be carrying freight.

You can build all the infrastructure you want but none of that matters if people won't take public transport. I don't do it because only the sketchiest, creepiest people take public transport in the US. You can't get on a train/bus/subway/whatever in this country without fear of getting stabbed.

Until that problem is addressed, cars aren't going away.

I know what you mean, but that turns out to be empirically untrue. Good transportation infrastructure encourages use in measurable ways (economists and urban planners call this "induced demand"). When you build out a train of bus network so that it's actually useful, people start using it.

When it comes to safety and public transportation, I think the causality works the other way. In places with excellent public transportation, like New York and Toronto, everyone, including the middle class, uses public transportation. Not coincidentally, these places also have very low crime: New York is in the bottom 20% of US cities for crime severity, and Toronto is the safest city in North America. Under investing in the well-being of poor people, including public infrastructure, causes crime.

I've used the public transportation in several large US cities, and have never felt threatened by or fearful of the other passengers.
