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.

Agreee, and a third thing. Gas usage for cooking is so small, it's really a non-issue.

Gas usage for heating is the big one we need to curtail. Having a culture war on cooking ranges is a distraction.

It's not a distraction so much as it's the bait. Gas cooking gets the utility serviced to the building, which enables the gas furnace vs electric heat pump conversation. Gas furnace is cheaper up front, so that's what goes into suburbia.

Builders and developers will always do the absolutely cheapest thing possible to stay competitive, and will only do better when they're either legislated to or consumers demand it. Home builders associations lobby to keep minimum requirements ... minimal, and most consumers just see pretty showers and big kitchen islands, so this is why we still build houses like it's 1980.

Always amuses me how many people care about gas mileage on a $50k car but couldn't give two shits if their $2m home is efficient.

Then you are living in an area that is running a bit behind.

Once you electrify heating, no one is going to pay for a gas line in new construction.

We (Netherlands) had these conversations go down like this 5 years ago. Now, no new home construction is running a gas line.

[–] chrizzowski@lemmy.ca 2 points 1 year ago

Canada, and yeah when it comes to how we build we are definitely behind. Oil and gas is so entrenched in the economy, especially western provinces, that any going against that is blasphemy to a significant chunk of the population. It will get better though. We can already do better, the incentive just isn't there.

I'm a certified passive house designer and I'm always jealous of all the products and materials available in Europe!

Do you guys all have fireplaces and generators?

[–] alvvayson@lemmy.world 3 points 1 year ago (1 children)

No, our electric grid has been extremely reliable.

[–] NoIWontPickaName@kbin.social 0 points 1 year ago (2 children)

I couldn’t trust that, and it only gets to like -11F around here.

[–] alvvayson@lemmy.world 2 points 1 year ago (1 children)

If you don't have reliable electricity, then get a generator or wood stove.

That's what rural folk do all around the world.

[–] NoIWontPickaName@kbin.social 1 points 1 year ago

That’s why I led with that

Wood stove as backup is pretty common in some parts of the US anyways. Heat pump + wood stove = not much physical labor + cheap to operate + backup heat for ice storms

[–] DroneRights@lemm.ee 4 points 1 year ago

However, gas stoves will still kill you. They won't kill the environment as bad as they kill you, true, but you're still dead.

[–] set_secret@lemmy.world 1 points 1 year ago

the issue about it being literally poisonous for humans is kind of a big deal, regardless of how much gas you use. Domestic range hoods do FA.

If you want to keep your gas stove despite the very real health implications, that is a poor choice.
