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.

I just want a robust cycling and public transportation infrastructure.

I want zoning reform for the higher density necessary to make those things viable.

(It also would vastly reduce the amount of concrete needed per capita, reducing CO~2~ emissions from its manufacture, and would also reduce HVAC energy use because multifamily buildings with shared walls are more efficient than single-family homes with all 6 sides exposed to the environment.)

(Frankly, it's amazing how many initially seemingly unrelated problems really boil down to bad zoning, once you follow the line of causation.)

I agree on the zoning reform. Never really paid much attention to it, or cared about it, until I started hanging around people pushing for bike infrastructure projects.

Are you saying you don't also want the 6 things they talk about on the article? The point is there's is broad public support for a range of good policies, so let's try to aggressively do those things. We can also work on other, harder things.

I'm a bike commuter and a strong towns type too, but despite this basket of policies being beneficial to everyone, it's like a prisoners dilemma of inaction. The chicken and egg game of removing parking and building transit is just exhausting and unfortunately doesn't poll well because most people can't think long term (or even medium term).

As bike commuter who's been run over and knows numerous people hit/killed by drivers, I stand by what I said. It's not that I don't want the other things, this is just something I'm deeply passionate about.

[–] spidermanchild@sh.itjust.works 3 points 5 months ago (1 children)

I respect that (and am also very passionate about this topic too). I was nearly hooked just yesterday while in our new "protected bike lane" by some asswipe in an SUV and fortunately braked hard early because of a weird feeling I had about them when I glanced over. I was just loosely trying to stay on topic here. Stay safe friend.

I feel like at the very least public transportation should be brought up in the conversations. I get why it doesn't poll well as a lot of people just associate it with criminals and homeless people, or at least what people have expressed to me about it. But definitely stay safe on the road!

That's exactly what they're doing. It's a common strategy reflect redirect and misdirect. What's the easiest way to stop climate positive initiatives? Cause disunity and fragmentation among those that support climate initiatives.
